Introduction
LS MT122 Sub-Compact Utility Tractor
The LS MT122 is a sub-compact utility tractor produced by LS since 2016. Designed for property maintenance, landscaping, and light agricultural tasks, this model serves as a versatile platform for residential and semi-professional operators requiring a balance of power and maneuverability.
Engine and Powertrain
The tractor is powered by a Yanmar 3TNV76F three-cylinder diesel engine. This liquid-cooled unit provides a gross power output of 21.5 hp (16.0 kW) at a rated speed of 3000 RPM. It utilizes indirect injection and meets Tier IV emissions standards. The powertrain is managed by a hydrostatic transmission, offering infinite forward and reverse speeds across two operational ranges, facilitating smooth direction changes without the need for manual clutching.
Hydraulics and PTO
The hydraulic system features a total flow capacity of 6.7 gpm (25.4 lpm), with 4.6 gpm dedicated to implement operation and 2.1 gpm reserved for the power steering system. Versatility is supported by an independent rear PTO (540 RPM) and an independent mid-mount PTO (2500 RPM), allowing the operation of various attachments such as mowers or rear-mounted implements.
Mechanical Configuration
Built on a 56-inch wheelbase, the MT122 utilizes a four-wheel-drive system for enhanced traction. Operator safety is addressed through a two-post folding Roll-Over Protective Structure (ROPS) and wet disc brakes. The machine weighs 1433 lbs, providing sufficient stability for its size class while remaining agile for work in confined spaces.
Hitch and Capacity
The rear of the tractor is equipped with a Category I three-point hitch. The system features position control to manage implement depth accurately. It offers a lift capacity of 728 lbs (330 kg) when measured at 24 inches behind the lift points, with a maximum capacity of 970 lbs (439 kg) at the link ends.
Conclusion
The LS MT122 is designed for users seeking a compact, reliable machine for routine maintenance and light-duty tasks. Its combination of hydrostatic transmission, independent PTOs, and standard four-wheel drive makes it a capable solution for landscaping and small-scale property management.
