The Honda H3011 is a riding lawn mower with small vertical general-purpose Honda GXV340K1 engine (337 cc, 20.6 cu-in) and 760 mm (30 in.) deck with belt drive that is adjustable in six increments for cutting heights between 25 mm (1 in.) and 90 mm (3.5 in).
The Honda GXV340K1 motor is an air-cooled single-cylinder four-stroke gasoline engine with vertical PTO shaft. An 82.0 mm (3.23 in) cylinder bore and 64.0 mm (2.5 in) piston stroke give the engine a total of 337 cc (20.6 cu-in) of displacement. Compression ratio rating is 7.7:1. The motor produces 11 HP (8.2 kW) at 3,600 rpm and 23.0 Nm (2.3 kg·m, 17.0 ft·lb) of torque at 2,500 rpm.
The Honda H3011 is available in two versions:
- H3011/H3011SA – model with Mechanical Auto-clutch Transmission (MAT);
- H3011H/H3011HSA – model with Hydrostatic Transmission (HST);
The gear type transmission uses parallel shaft, constant mesh and sliding key. The gear transmission has five forward gears from 2.4 km/h to 7.9 km/h (1.5 mph to 4.9 mph) and one reverse gear 2.8 km/h (1.7 mph).
The hydrostatic transmission. The transmissiom has three approximate ground speeds: Reverse from 0 to 2.7 km/h (0-1.7 mph), Mowing from 0 to 5.3 km/h (0-3.3 mph) and Transport from 5.3 to 7.2 km/h (3.2-5.3 mph)

I’ve had a Hydro 3011 since the early 90’s. Frankly this is one of the best machines ever made and produced at the peak of Japanese quality. The xmission is right up there with the same era Civic cars. It has literally been a lifesaving machine for decades and other than the gas tank has yet to drip a drop of fluid.
