Enhanced Productivity
ST37XEnhanced Productivity
Designed for jobsite versatility, the ST37X is the ideal machine for creating footings on residential or commercial properties, installing drainage pipe and other trenching and landscape tasks.
Heavy-duty chain with 50,000-lb tension creates a cleaner, more consistently deep and wide trench than an excavator can, and in less time.
Standard auto-throttle—incorporated into the LCD display—reduces engine throttle when there is no load on the engine for more efficient operations.
The machine’s compact package increases productivity on tight jobsites.

Comfortable Operator Platform
ST37XComfortable Operator Platform
Designed with operator comfort in mind, the machine is equipped with a best-in-class, 332-in2 (843-cm2) operator platform for outstanding comfort, stability and productivity during long working hours.
The spring-supported platform is larger and provides more ground clearance than the competition’s.
Standard dual-lever ground drive controls allow the operator to control each machine track independently for improved mobility on difficult jobsite conditions.
An advanced LCD display is mounted in the dash to provide direct visibility into engine diagnostics.

Best-in-Class Power
ST37XBest-in-Class Power
Powered by a Tier 4 Yanmar® diesel engine, the 37-hp (27.6-kW) machine provides best-in-class power for all machine functions.
Maximum 4.7-mph (7.6-km/h) ground drive speed, in both forward and reverse, enhances jobsite efficiency.
With a dedicated, integrated digging system, the machine allows for more power and increased productivity on footings and landscape jobs.
An auxiliary control foot pedal helps you maintain hydraulic flow to the trencher, freeing operator hands to control depth and ground speed.

Innovative, Construction-Grade Design
ST37XInnovative, Construction-Grade Design
Built for heavy-duty operation, the ST37X is designed for overall machine longevity and contractor ROI.
Designed for creating footings on residential and commercial properties, installing drainage pipe and other trenching and landscape duties, the machine trenches up to 16 in (41 cm) wide and up to 36 in (91 cm) deep.
A multi-position trencher—centerline to offset digging—allows operators to trench directly next to the backer board.
With 43 in (109 cm) of track on the ground, the machine has the stability to effectively cross-trench for added jobsite versatility.
The machine has no daily maintenance points and no grease zerks, improving ease of maintenance and reducing total cost of ownership.
