Tracked Skid Steer 2k
The ST31 matches the compact size of a medium frame with lift capacity of larger loaders. The vertical lift arm, 125 inch lift height and 74hp regeneration free engine, make the ST31 an accomplished material handler, perfect for use in a wide range of applications, from moving palletized material around a construction site to truck loading. The wide, double-steel reinforced tracks provide stability and reduced total cost of ownership.
Controls for Every Operator
- Mechanical hand-foot controls allow the user to operate boom and bucket controls via foot pedals and machine steering via hand levers. Selectable EH joystick controls: Control patterns can be toggled between ISO and H-Pattern via a switch in the cab. Sensitivity can be adjusted to the operator’s preferences. With adjustable sensitivity and control patterns, the loader is designed to fit the control preferences of nearly any user.
- Different types of controls ensure that operators with different backgrounds and experience can operate efficiently.
- Choose between mechanical hand-foot controls and selectable EH Joystick Controls with ISO and H patterns.
Two-speed transmission
- Two speed transmission provides increased travel speeds to reduce work cycle times and increase productivity.
5.7-inch Color Display
- The full color deluxe display allows for customizable machine settings and operating parameters, as well as, error codes and maintenance reminders.
- Pair with the optional rearview camera to enhance visibility and jobsite awareness
Maximum Visibility
- Low mounted tilt cylinders, expansive door, sloped rear engine compartment and large side windows maximize operator visibility in every direction.
Forward Tipping Cab
- Whether the lift arm is fully raised or on the boom stops, a forward tipping cab provides ample access to hydraulic pumps and motors.

Features
Maintenance
Maintenance and Filter Free After-treatment
- Maintenance, and regeneration free aftertreatment eliminates extreme heat and reduced performance during regeneration.
- Equipped with a passive Diesel Oxidation Catalyst (DOC) and Exhaust Gas Recirculation requiring no maintenance, reducing Total Cost of Ownership (TCO).
Expansive Maintenance Access
- Things break, and repairs are required, it’s fact of life. The forward tilting cab and simple arrangement of internal components limit downtime when things go wrong.
- A spacious engine bay, coupled with a swing up cooling package, provide convenient access to hydraulics and the engine.
4 year / 4000 hour Engine Warranty
- Kohler KDI engines come with industry-leading 4 year, 4,000 hour warranty, so both first and second life owners can be assured that their engine will be operating smoothly for years to come.
Performance
Variable Speed Fan
- Runs on an as-needed basis to help reach optimal operating temperature faster and then maintain it to improve performance and efficiency.
- Reduced fan speed greatly decreases fan noise to the operator and the surrounding environment.
Efficiency
High Hinge Pin Height
- Maximizes loading and unloading capabilities for any industry and on any jobsite.
Comfortable, Spacious Cab
- The loader comes with a spacious extended cab, that maximizes room and comfort for the operator to move inside the cab.
Ergonomic cab design
- From switch location and layout to an angled foot rest in the floor board, the cab was purposefully designed to reduce operator fatigue.
- Ergonomically located handles, a wide door and step make entry and exit easy for any operator.
- Joysticks, armrests, and seat are all connected and move as one unit making it more comfortable and easier to operate in rough environments.
