It features a two-wheel drive system and utilizes a mechanical idler pulley clutch for engaging the independent mid-PTO, providing the operator with manual control over the cutting attachment.

The machine features an open operator station designed for visibility. Steering is managed via a manual system, while stopping power is provided by disc brakes. The tractor rides on lawn/turf tires, with 13x5.00-6 in the front and 18x9.50-8 in the rear to minimize soil compaction and maximize traction on grass surfaces.
