SCAG STHM 3-Wheel Hydro-Rider Mower

A proven efficiency leader, the durable out front cutter deck design of the Scag STHM, delivers maximum stability, outstanding manoeuvrability, and superior trimming performance, providing excellent mowing access under and around trees and shrubs.

The STHM's reliable hydrostatic drive system is more powerful, runs smoother and lasts longer than any commercial hydrostatic transaxle drive on the market today. Controlled by a single foot pedal, two high-powered cast-iron wheel motors work in conjunction with a high-efficiency pump to evenly distribute power to both drive wheels.

This mower features an ultra-low centre of gravity that gives it incredible hillside stability with outstanding reach. Available as 61" or 72" cutter decks with 23hp engine, the STHM is a serious mowing machine.
