Your Guide to Skid Steers: Uses, Parts, Attachments & More

What Is a Skid Steer?

A skid steer is a compact, highly maneuverable loader that uses independently controlled wheels on its left and right sides to move and turn. Instead of steering by turning its wheels left or right like a car, a skid steer changes the speed or direction of the wheels on each side. This allows the tires to skid across the ground as the machine turns, which is where the name “skid steer” comes from.

Most skid steers have four wheels, a cab between two loader arms and a quick coupler at the front for connecting a bucket or another attachment. Change the attachment and the same machine can load dirt, move pallets, drill holes, clear brush, remove snow, dig trenches and handle many other jobs.

Is a Skid Steer the Same as a Skid Loader?

Generally, yes. Skid steer, skid steer loader and skid loader are commonly used to describe the same general type of machine. “Skid steer loader” is the more complete term. “Skid steer” is the common shortened version, while “skid loader” is another name you may hear on jobsites or see while researching equipment.

The important distinction is between a skid steer loader and a compact track loader. They can look very similar, but a skid steer runs on wheels while a compact track loader runs on tracks (we cover this difference in more detail below.)

How Does a Skid Steer Work?

A skid steer’s steering system is one of the features that makes it unique. The wheels on the left side operate together, and the wheels on the right side operate together. The two sides can be driven at different speeds or in different directions.

If both sides move forward at the same speed, the machine travels straight ahead. If one side moves faster than the other, the skid steer turns. For a very tight turn, the two sides can move in opposite directions. As that happens, the tires slip or “skid” across the ground while the machine pivots.

That ability gives skid steers a very small turning radius and makes them useful where there is not much room to maneuver.

What Happens During a Turn?

Imagine looking down at the machine from above. To turn left, the wheels on the right can travel faster than those on the left. For an even tighter turn, the right wheels can travel forward while the left wheels travel backward. The machine then rotates instead of following the wider curved path you would expect from a vehicle with conventional steering. The tradeoff is that the tires must slide across the surface during tight turns, which can disturb loose soil, grass and other sensitive surfaces.

How Do the Loader Arms Work?

The loader arms run alongside the cab and support the attachment at the front of the machine. Hydraulic cylinders raise and lower the arms, while another part of the hydraulic system controls the angle of the bucket or other attachment.

Different skid steers use different lift-linkage designs. Some follow a radial lift path, while others use a vertical lift design. The difference affects how the attachment moves as the arms are raised.

What Does the Hydraulic System Do?

The machine’s engine powers hydraulic systems that operate the loader arms and attachment functions. Auxiliary hydraulic connections can also send hydraulic power to compatible attachments, which is what makes powered work tools such as hydraulic hammers, augers, trenchers, brush cutters and brooms possible.

The Main Parts of a Skid Steer

1. Cab and Operator Area

The cab, or operator station, sits near the center of the machine between the loader arms. This is where the operator controls travel, steering, loader-arm movement and attachments. Depending on the machine and configuration, controls may include joysticks, pedals, switches and an electronic display. Protective structures around the operator area are also an important part of the machine. Current Cat skid steer specifications, for example, include rollover protective structures and falling object protective structures as part of the cab configuration.

2. Loader Arms

The loader arms connect the machine to the front attachment and allow it to be raised and lowered. When loading a truck, for example, the arms lift the bucket above the truck body. During grading or digging, they position the bucket closer to the ground.

3. Bucket or Other Work Tool

A general-purpose bucket may be the attachment people most closely associate with a skid steer, but it is only one option. Depending on the job, the front of the machine can be equipped with forks, grapples, augers, trenchers, brooms, hammers and many other work tools.

4. Attachment Coupler

The coupler is the connection point between the loader and its attachment. Its purpose is to make it practical to change compatible work tools without treating the attachment as a permanent part of the machine. This ability to switch tools is a major reason skid steers can handle so many different jobs.

5. Hydraulic System

Several parts work together to create and control hydraulic power.

  • Hydraulic pumps create the flow needed to operate hydraulic functions.
  • Hydraulic lines and hoses carry hydraulic fluid through the system.
  • Hydraulic cylinders convert hydraulic pressure into movement, such as raising the loader arms or tilting a bucket.
  • Auxiliary hydraulics provide hydraulic power to compatible powered attachments.

6. Engine

The engine supplies the power needed to move the machine and operate its hydraulic systems. Horsepower matters, but it should not be considered by itself when comparing skid steers. Machine weight, rated operating capacity, hydraulic performance, lift geometry and attachment requirements can be just as important for a job.

7. Wheels and Tires

Traditional skid steer loaders use four wheels, with two on each side. The tires support the machine, transfer power to the ground and play a direct role in steering. Tire selection can also affect traction, ride characteristics and performance on different surfaces.

8. Drivetrain

The drivetrain transfers power so the wheels on each side of the machine can be controlled. Independent control of the two sides is what makes skid steering possible. For someone comparing machines, the key point is not the internal mechanical detail. It is that a skid steer does not depend on conventional front-wheel steering to change direction.

9. Lift Cylinders, Tilt Cylinders and Linkage

The loader arms do not work alone. Lift cylinders raise and lower the loader mechanism. Tilt cylinders control the angle of the attachment. The linkage connects these components so the operator can position the attachment throughout its working range.

10. Rear Structure and Machine Balance

A skid steer has to remain stable while carrying material in front of the machine. Machine design, weight distribution, attachment weight and load all affect that balance. Some models offer counterweight configurations that change rated operating capacity, which is one reason operators should use the capacity specifications for their exact machine rather than relying on a general skid steer number.

Each of the above parts play a different role, but they all work together to make a skid steer the compact, maneuverable and versatile machine it is.

Here’s a quick reference table that brings these points together:

Topic  What to Know
What it is A compact loader with independently controlled left and right wheels
How it steers By varying the speed or direction of the wheels on each side
Typical uses Loading, grading, digging, material handling, landscaping, snow removal and cleanup
Weight Varies substantially by model and configuration
Main components Cab, engine, drivetrain, wheels, loader arms, hydraulic system, coupler and attachment
Common attachments Buckets, forks, grapples, augers, trenchers, brooms, hammers and snow tools
Ground contact Four tires rather than a tracked undercarriage
Key capacity measurement Rated operating capacity, or ROC

What Is a Skid Steer Used For?

One of the biggest advantages of a skid steer is its versatility. While the machine itself provides the power, mobility and lifting capability, the attachment on the front largely determines the work it can perform. By switching between buckets, forks, grapples, augers and other work tools, the same skid steer can take on a wide range of jobs.

Loading and Moving Material

Loading and moving material is one of the most common uses for a skid steer. With a bucket, operators can scoop, carry and load dirt, gravel, mulch and other loose materials. That makes skid steers useful for everything from cleaning up a jobsite to moving material around a property or loading it into a truck.

Grading and Site Preparation

Skid steers are also commonly used to spread, level and grade material. Buckets, grading attachments and rakes can help prepare areas for landscaping, construction and other projects. Their compact size and tight turning ability are especially useful when working in areas where maneuvering a larger loader would be difficult.

Material Handling

Switching from a bucket to pallet forks turns a skid steer into a compact material-handling machine. Forks can be used to lift and transport pallets, building materials and other loads around a jobsite, as long as the load and attachment are within the machine’s rated capacity.

Digging and Trenching

For basic digging, a bucket can be used to remove soil and prepare smaller areas. More specialized attachments, such as trenchers and augers, allow skid steers to handle tasks like cutting trenches or drilling holes. A skid steer won’t replace an excavator for every digging application, but its attachment options make it useful for many smaller excavation and site-preparation projects.

Landscaping and Land Clearing

The combination of compact size and attachment versatility makes skid steers well suited for many landscaping and land-clearing jobs. They can move soil and mulch, grade areas, remove brush and clean up properties. Grapples, rakes, brush cutters and other attachments can expand the types of vegetation and debris the machine can handle.

Demolition and Cleanup

On demolition and cleanup projects, the compact dimensions of a skid steer can be an advantage in areas with limited working space. Buckets and grapples can collect and move debris, while hydraulic hammers and other specialized attachments can be used for certain demolition tasks.

Agriculture

Skid steers are commonly used for a variety of jobs around farms and agricultural properties. Depending on the attachment, they can move feed or bedding, clean barns, handle pallets, move material and take care of other everyday chores.

Roadwork and Property Maintenance

Skid steers can also handle a range of general maintenance tasks. With the right attachment, they can sweep paved surfaces, move material, grade roads or lots, clear debris and perform other work needed to maintain jobsites, roads and properties.

How Much Does a Skid Steer Weigh?

Skid steers commonly weigh several thousand pounds, but there is no single standard skid steer weight. Machine size, engine, cab configuration, tires, bucket, counterweights and other equipment can all affect operating weight.

To give you an idea of how broad that range can be, here’s an example of different Cat loaders:

Example Machine Published Operating Weight Rated Operating Capacity
Cat 226D3 5,849 lb 1,550 lb
Cat 236D3 6,567 lb 1,800 lb
Cat 242D3 7,138 lb 2,200 lb
Cat 250 7,829 lb 2,689 lb
Cat 260 8,523 lb 3,160 lb
Cat 270 10,441 lb 3,557 lb

What Does Operating Weight Mean?

Operating weight is intended to represent the machine in a working configuration rather than simply the weight of an empty machine. The exact conditions used to calculate it matter. Published Cat specifications may account for items such as fluids, an operator, tires, a bucket, cab configuration and coupler.  That’s why it’s important to read the notes accompanying a specification instead of assuming every manufacturer or model is being measured in exactly the same configuration.

Why Weight Matters

Weight is particularly important when transporting a skid steer. The machine itself is only part of the load. You also need to account for the bucket or other work tools being transported, along with the trailer and any additional equipment or material. Knowing the actual machine and attachment weights helps with trailer selection, towing and hauling planning, loading and jobsite access.

Common Skid Steer Attachments

Attachments are one of the biggest reasons skid steers can perform so many different jobs. The table below breaks down some of the most common options. 

Attachment Typical Purpose
General-purpose bucket Digging, loading and moving loose material
Grapple Handling brush, debris and irregular material
Pallet forks Moving palletized loads
Auger Drilling holes for posts, footings and similar work
Trencher Cutting narrow trenches
Hydraulic hammer Breaking concrete, rock and other hard material
Brush cutter Cutting grass, brush and vegetation
Broom Sweeping pavement and jobsites
Snow blade Pushing snow
Snow blower Collecting and throwing snow
Rake Landscaping and surface preparation
Stump grinder Grinding tree stumps
Compactor Compacting certain materials

Fabick Cat offers attachments and work tools for skid steer and compact track loaders, including tools designed for jobs ranging from drilling to material movement and sweeping.

Understanding Skid Steer Sizes

Skid steer sizes are different from machine to machine. That’s why, when comparing models, it’s important to consider how the machine’s size, power and capacity fit the work you need to do. Here’s some things to consider: 

  • Operating weight: How much the configured machine weighs.
  • Rated operating capacity: A practical measure of how much load the machine is rated to handle under specified conditions.
  • Horsepower: An indication of engine output, but not a complete measure of machine capability.
  • Lift height and reach: Important when loading trucks or placing material.
  • Overall dimensions: Width, height and length can determine whether a machine can access a particular work area.
  • Hydraulic capacity: Especially important if the machine will operate powered attachments.

Just remember that bigger and more powerful does not always mean better. A smaller skid steer with the right capacity and attachments may be a better fit for tight spaces and lighter work. For jobs that involve heavier lifting or demanding hydraulic attachments, a larger machine with greater hydraulic performance may be the better fit

What Is Rated Operating Capacity?

Rated operating capacity, commonly abbreviated ROC, tells you how much load a skid steer is rated to handle under defined operating conditions.  It should not be confused with operating weight. Operating weight describes the weight of the machine itself in a specified configuration. Rated operating capacity describes a working load capacity. For example, the Cat 250 has a published operating weight of 7,829 pounds and a rated operating capacity of 2,689 pounds. Those numbers describe two completely different things.

Understanding Radial Lift vs. Vertical Lift

One important difference between types of skid steers is the path the lift arms follow. Most use either a radial lift or vertical lift design. 

Radial Lift

A radial-lift design moves the attachment outward along an arcing path as the arms rise. This design can provide useful reach around the middle of the lift cycle and is commonly associated with applications where much of the work happens closer to ground or mid-lift height. For example, the Cat 236D3’s radial lift design provides mid-lift reach which is great for digging performance.

Vertical Lift

A vertical-lift design is intended to keep the attachment moving more vertically as it rises, providing additional reach at higher lift positions. This can be useful for jobs such as loading trucks or handling material at height. Current Cat 250 and 260 skid steers use vertical lift designs and which gives them extended reach and lift height for truck loading.

Comparing Skid Steers vs. Compact Track Loaders

Skid steer loaders and compact track loaders can look almost identical from the cab upward. The obvious difference is underneath the machine. A skid steer uses wheels and tires, while a compact track loader uses a tracked undercarriage.

The table below breaks down the differences in more detail.

Skid Steer Loader Compact Track Loader
Runs on tires Runs on tracks
Skid-steers using left and right wheel movement Uses similar differential steering principles through tracks
Well suited to many firm surfaces Offers a larger ground-contact area
Often highly maneuverable on hard surfaces Often selected where flotation and traction are priorities
Tire wear and maintenance are key considerations Undercarriage wear and maintenance become important considerations

Main Advantages of Skid Steers

Compact Dimensions

Their size allows them to work in places where larger loaders may have difficulty maneuvering.

Tight Turning

Independent left and right drive allows extremely tight turns.

Attachment Versatility

Changing work tools can turn the same carrier into a loader, material handler, auger, trencher, sweeper, snow-removal machine and more.

Transportability

Although skid steers can still weigh several tons, their compact dimensions can make them easier to move between jobs than many larger machines. Proper towing equipment and weight calculations are still essential.

Broad Range of Applications

Construction, landscaping, agriculture, maintenance and material handling can all make use of the same basic machine.

Limitations and Considerations to Know

Ground Disturbance

The same skidding action that allows tight turns can disturb turf, loose soil and other sensitive surfaces.

Ground Conditions

A wheeled skid steer may not provide the same flotation or traction as a compact track loader in some soft or challenging conditions.

Capacity

Every machine has limits. Rated operating capacity, attachment weight and lift requirements should be matched to the job.

Hydraulic Requirements

Powered attachments may require particular hydraulic flow and pressure capabilities.

Attachment Compatibility

Not every attachment is appropriate for every skid steer, even if the machines and tools look similar.

Lift Requirements

Jobs involving high-sided trucks or placement at height may place more emphasis on lift height, reach and lift-path design.

How to Tell Which Type of Skid Steer is Best for You

When choosing a skid steer, start with the work rather than the machine.  Ask yourself these questions:

  1. What jobs will the skid steer perform most often? Loading dirt creates different requirements than operating a hydraulic brush cutter or placing pallets.
  2. How much does the material weigh? Use that information when evaluating rated operating capacity.
  3. Which attachments will you need? Check both physical compatibility and hydraulic requirements.
  4. How much room is available? Machine width, height, length and turning clearance can matter on confined sites.
  5. How high do you need to lift? Consider lift height, reach and radial versus vertical lift geometry.
  6. What are the ground conditions? This can help determine whether a wheeled skid steer or tracked machine is more appropriate.
  7. How will the machine be transported? Use the actual operating weight and attachment weights when planning transportation.
  8. Will you buy or rent? A frequently used machine may justify ownership, while rental can make sense for temporary needs or specialized projects.

If you only need a skid steer for a single project, Fabick Cat offers rental options that include skid steer loaders and work tools.
