Tiller Trolley which is a tractor with one axle, self-powered and self-propelled, which can pull and power various farm implements such as a trailer, cultivator or harrow, a plough, or various seeders and harvesters. The operator usually walks behind it or rides the implement being towed. A further distinction is seen in the two-wheeled tractor’s ability to operate disparate types of agricultural equipment, while rotary tillers are smaller and specialize in soil tillage.
