摘要： A mower with a hitch system allows large lateral offsets in both directions of the mower relative to a towing vehicle. The mower hitch system includes first and second swing arms spaced apart across the mower. First and second pivot shafts mount the respective first and second swing arms on the mower for pivotal movement of the arms about respective upright axes spaced apart across the mower. The swing arms extend towards a front end of the mower for connecting to lift arms of a three point hitch on the towing vehicle. A lug extends from the first pivot shaft such that the first swing arm and the lug form a bell crank. A hydraulic cylinder mounted on the front end of the mower connects to the lug such that extension and contraction of the cylinder pivots the first swing arm laterally over the cylinder and across the mower. The towing vehicle also includes a power take off for connecting to a telescoping drive shaft assembly with universal joints on the mower. The mower includes a primary gearbox with an input connected to the drive shaft assembly and two secondary drive shafts positioned on opposite lateral sides of the primary gearbox for driving respective mower blades. Two secondary drive shafts connect the primary gearbox to the respective secondary gearboxes. The primary gearbox is mounted rearwards of the secondary gearboxes.

摘要： An agricultural implement has a working position extending laterally behind a towing tractor and a transport position in which it is towed endwise behind the tractor. The implement has ground wheels that support the implement in both working and transport positions. These are rotatably mounted on the implement frame and are coupled to the hitch pole and the instrument by a steering linkage so that as the hitch pole moves between its working and transport positions, the wheels are steered between their respective working and transport positions.
