The deck is adjustable in six increments for cutting heights between 25 mm (1 in.) and 90 mm (3.5 in).

The Honda GXV340 K1 is general-purpose air-cooled single-cylinder four-stroke gasoline engine with vertical PTO shaft. It has an 82.0 mm (3.23 in) of the cylinder bore and 64.0 mm (2.5 in) of the piston stroke. Compression ratio rating is 7.7:1. The Honda GXV340 K1 engine produces 11.0 HP (8.2 kW) at 3,600 rpm of maximum horsepower and 23.0 Nm (2.3 kg·m, 17.0 ft·lb) at 2,500 rpm of peak torque.

The Honda H1011 is available with two transmissions:

  • The gear type transmission uses parallel shaft, constant mesh and sliding key. It five forward gears with travel speed from 2.4 km/h to 7.3 km/h (1.5 mph to 4.5 mph), neutral gear and single reverse gear 3.7 km/h (2.3 mph).
  • The hydrostatic transmission uses sealed hydrostatic motor and pump. This transmissiom has three approximate ground speeds: “Reverse” from 0 to 3.4 km/h (0-2.1 mph), “Mowing” from 0 to 5.2 km/h (0-3.2 mph) and “Transport” from 5.2 to 6.6 km/h (3.2-4.1 mph).
