RE: tractor
A hand tractor can move back and forth at a certain speed because the rotation of the drive motor shaft is supplied to the wheels. There are three types of wheels used on hand tractors, namely: tire wheels, iron wheels, float wheels (wheel cage / cage wheell). The tire wheel works for transportation. and cultivate dry land. The surface shape of the tire wheel is grooved slightly to prevent slippage. Tire wheels can reduce vibration, so as not to damage the road. Iron wheels are used for piracy on dry land. The fins on the iron wheels will stick to the ground, thus reducing the occurrence of slippage when pulling heavy loads. In this hand tractor uses Floating Wheel because it is used during the processing of wet soil. These floating wheels have a wide, there is also a large diameter, so it can withstand the load of the tractor so as not to drown in the mud. Wheel size adjusted to tractor specifications. The size of the wheel will affect the speed of the tractor.
