Agricultural tractor with tracked rear wheel pairs - has additional three point linkages mounted at front and sides (NL 11.4.78)

摘要

The agricultural tractor has front rear and centre power operated three point implement lifts. The centre lift is located to the rear of the front wheels and consists of two three point side lifts arranged symmetrically to the vertical longitudinal centre plane of the tractor. The rear wheel sets on each side of the tractor are coupled by an endless track (13). The endless track serves as a support which can be raised when so required by hydraulically operated parallelogram arms (49, 50). The support wheel or track diameter is greater than that of the road wheels (3).
