专利汇可以提供Wheel suspension means for agricultural machine专利检索,专利查询,专利分析的服务。并且A tractor drawn and powered agricultural machine, such as mowerconditioner for hay-like crops, comprises a main frame having a pair of spaced apart side walls between which a sickle mower, a tine reel, a pair of conditioning rolls, a crop gathering hood and windrowing means, and a pair of transport wheel assemblies are mounted. A hitch pole or tongue is pivotably connected by a non-binding vertical hinge to the main frame outboard of one of the side walls and is laterally movable to selected positions wherein it is releasably engaged by a remotely operable pin. Operating power from the tractor is supplied through a rotatable power take-off shaft to a transmission unit on the main frame outboard of one side wall. The transmission unit is connected to and drives the conditioning rolls and the sickle mower. The tine reel, which is adjustably mounted on the side walls, is chain driven from the upper conditioning roll. The two transport wheel assemblies, each of which includes an independently sprung torsion-bar supported wheel, are mounted on a rockshaft which is rotatably adjustable by means of a remotely controlled hydraulic actuator to change the height of the main frame above ground. Adjustable skid shoes beneath the main frame determine the minimum height of the main frame above ground. The rockshaft is adjustably movable laterally to change the angle between its axis and the sickle-bar mower to account for differences in drag offered by various crops and ground conditions. A float lock system is provided to assist the torsion bars (i.e., suspension springs) when the hydraulic actuator is extended to raise the implement to transport height.,下面是Wheel suspension means for agricultural machine专利的具体信息内容。
