Abstract: A grain drill adapted to be towed in a forward direction during a planting operation and supported by a forwardly disposed caster wheel and rearwardly disposed non-caster wheels. A pair of transport units is attached to the frame of the drill rearwardly of the non-caster wheels. Each unit includes a pair of transport wheel assemblies interconnected by a hydraulic power unit for swinging transport wheels between raised and ground-engaging positions. In the ground-engaging position the non-caster wheels are supported off the ground and the drill is supported for transport in either forward or endwise directions.
