ABSTRACT:
A plurality of grain drills are coupled together in end-to-end relation for towing behind a tractor for operation and alternately in an endwise direction for transport. Each drill is supported in field operation by a forward caster wheel and a plurality of side-by-side gangs of press wheels disposed along the rear of the drill. The drills are coupled to the tractor for operation by duplex (or triplex) hitch structure. For endwise transport an endmost drill is provided with a hitch swingable to a transport position for coupling to the tractor. A single transport wheel is mounted on the rear of this drill for movement to a position providing endwise transport. A press wheel gang lock mechanism is arranged for movement to a position locking the gangs against downward movement in response to swinging the endwise hitch to its transport position. This leading drill is thus supported in transport by the front caster wheel, the transport wheel, and the tractor through the endwise hitch.
The second and subsequent drills are each provided with two transport wheels at the rear of the drill arranged for movement to a lowered transport position wherein the drill is supported for transport by these transport wheels and the front-mounted caster wheel. A press wheel gang lock mechanism is arranged on each of these drills for movement to a position locking the gangs against downward movement in response to moving the transport wheels to their lowered transport positions.
