Track shoe type follows the ground: single-grouser shoes grip soft soil, double-grouser shoes stabilize loader work, and flat shoes or street pads protect hard surfaces. Match the shoe to the application and the machine class, and confirm the approved sizes and bolt patterns before ordering. The shoe is the interface between the machine and the ground, so the choice is an application decision, not a preference.

The Job of a Track Shoe: Traction, Flotation, and Surface
The track shoe is the part that meets the ground, and it decides traction, flotation, and surface damage. Grouser height, width, and pattern are chosen for the work the machine does, and every design trades one benefit for another.
In Saskatchewan, machines switch between field work, gravel yards, and municipal sites. The shoe type that protects a lawn will spin on soft soil, and the shoe that grips mud will mark a finished lot — the type has to match the dominant work.
Single Grouser: Traction and Common Use
Single-grouser shoes have one raised bar and provide strong traction in soft soil and general excavation. They are the most common shoe for excavators and many dozers because the single bar bites deep and sheds material cleanly.
The single bar bites into soft ground and sheds material as the track rolls. It is a good all-round choice for machines that work in dirt, and it remains the default when a machine does a little of everything.
Double Grouser: Stability and Loader Work
Double-grouser shoes have two bars and spread the load more evenly, which suits loader work and firmer ground. The extra bar reduces sink and provides stable support under load, at a small cost in soft-soil bite.
For compact track loaders and machines that work on gravel or semi-firm ground, double-grouser shoes balance traction with stability. The pattern is the middle choice that most mixed-use machines settle on.
Flat Shoes and Street Pads for Hard Surfaces
Flat shoes and street pads are designed for concrete, asphalt, and finished surfaces. They protect the ground and ride smoothly, at the cost of traction in soft soil and reduced bite on slopes.
Municipal and landscaping machines often run flat shoes or bolt-on rubber pads to protect the surfaces they are paid to maintain. On a finished lot, the surface damage a steel shoe causes can exceed the cost of the shoe set many times over.
Matching Shoe Type to Application
Match the shoe to the dominant application: single grouser for soft soil, double grouser for loaders and firm ground, flat or padded for finished surfaces. Rental fleets usually standardize on a middle choice so one set covers most jobs.
The dominant application rule keeps the decision simple: list the machine's main jobs, count the hours on each surface, and pick the type that covers the majority. Mixed fleets can keep a second set for the seasonal job that changes the ground.
Shoe Type and Rental Machines: The Middle-Choice Standard
Rental machines cannot follow the renter's ground, so fleets standardize on the type that covers the most jobs without a change-out. Double-grouser shoes are the usual middle choice, with a padded set kept for the surface-sensitive contracts.
The rental standard is a business decision, not a technical one: one shoe type that rarely needs changing beats a perfect shoe that is wrong for half the rentals. When a rental contract includes a surface clause, the padded set travels with the machine.
Sizing Shoes to Machine Class
Shoe width and bolt pattern must match the machine class and chain. Confirm the approved shoe sizes and the part numbers for your model before ordering, because the type is only half the fit.
The approved range comes from the parts book for the serial number, and the bolt pattern settles the mounting. A shoe with the right grouser pattern and the wrong bolt pattern is still the wrong shoe.
Confirm the hardware with the shoe order, because a type change also changes the mounting set in some configurations. One order with the shoes and the hardware confirmed is one delivery and one job.
Shoe Types at a Glance: A Decision Table
When the application is clear, the type choice narrows quickly. The table below summarizes the three families and the conditions that suit each one.
| Shoe type | Best conditions | Watch out for |
|---|---|---|
| Single grouser | Soft soil, general excavation | Marking finished surfaces |
| Double grouser | Loader work, gravel, firm ground | Less bite than single in deep mud |
| Flat or street pad | Concrete, asphalt, finished lots | Poor traction in soft soil |
Changing Shoe Type on a Machine: What to Check First
Changing shoe type is allowed within the approved sizes for the machine class, but the bolt pattern and part numbers must be confirmed first. A type change also changes ground pressure and surface disturbance, which matters on jobs with site limits.
Check the parts book for the approved options, confirm the bolt pattern, and order the matching hardware. On a Saskatchewan machine that crosses between field and municipal work, a seasonal shoe change can protect both the crop and the contract.
The change is also a chance to inspect the chain seat and the hardware: a shoe change exposes the link faces and bolt holes that the old shoe covered. Confirming the seat condition before the new set goes on prevents the new shoes from inheriting an old problem.
Shoe Types and the Parts Book: Where the Options Live
The parts book for the serial number lists the approved shoe types and their part numbers, and the list is the boundary for every choice on this page. The type, width, and bolt pattern all come from the same page, and they are confirmed together.
When the machine's history is unknown, the old shoe's part number is the starting point and the parts book is the confirmation. The two together settle the type faster than a model-name search.
Conclusion
Track shoe type follows the ground: single grouser for soft soil, double grouser for loader work, flat or padded for finished surfaces. Match the type to the application and the size to the machine class.
Key Takeaways for Canadian Operators
- Use single-grouser shoes for soft soil and general excavation.
- Use double-grouser shoes for loader work and firm ground.
- Use flat shoes or pads for concrete, asphalt, and finished lots.
- Confirm shoe width and part numbers against the machine class.

Frequently Asked Questions
What is the difference between single and double grouser shoes?
Single-grouser shoes have one bar for traction in soft soil; double-grouser shoes have two bars for more even load support on firmer ground.
When should I use flat track shoes?
Use flat shoes on concrete, asphalt, and finished surfaces where protecting the ground matters more than traction in soft soil.
Can I change track shoe types?
Yes, within the approved sizes for the machine class. Confirm the bolt pattern and part numbers before changing.
