ATM 72LC Hillside Mower

Slope Mower by Harper

A safer solution to mowing slopes, the ATM 72LC keeps the operator and the engine upright on hills up to 34 degrees. The two halves of the 72 inch deck float independent for a quality cut in ditches and rough terrain. This superior technology balances greater comfort and control, decreasing rollover risk.
