ATM 162 Hillside Mower

Slope Mower by Harper

The leader in all-terrain mowing technology, the 162 provides a level of safety and comfort unmatched by a traditional tractor and batwing mower. The Poclain TwinLock wheel function offers an anti-slip solution, especially when turning on an incline. The fiberglass hood easily flips forward for engine maintenance. While the 162’s climate-controlled cab shelters the operator from the elements, it also pivots forward to access the hydraulic and electrical systems. This 162 offers the most power, protection and control in a slope mower.
