Abstract: A lever assembly includes a lever pivotally coupled to a housing for movement in a fore-and-aft direction and in a transverse direction. A guide plate is fixed to an end of the housing and has a guide slot which receives the lever. The guide slot has a fore-and-aft extending main slot. The guide slot also has first, second and third fore-and-aft extending sub-slots spaced apart from the main slot. Each of the sub-slots is connected with the main slot by a transverse extending connecting slot. A sector member is pivotally mounted between the housing and the lever. A first magnet is mounted on the lever. A second magnet is mounted on the sector member. Hall effect sensors are mounted on the housing. The sector member, the magnets and the Hall effect sensors cooperate so that signals are generated representing the position of the lever within the guide slot. A lever return spring is biased to urge the lever towards an aft end of the main slot.

Abstract: A collar shift type transmission is arranged to provide an increased number of speed changes from a reduced number of gears and shafts. The transmission has a main shaft, an output shaft and two intermediate shafts with a plurality of intermeshing gear sets located about each shaft. Collar shift elements for engaging different gears to provide a multiplicity of speed and range changes are provided only on the main shaft and one intermediate shaft. Arrangement of the gears of each set in pairs maximizes the number of gear changes while minimizing the required number of gears, collar shift elements and control mechanisms. The main shaft preferably is provided with synchronizer clutches and close coupled to the driven portion of a main clutch to minimize the momentum transfer through the synchronizers. A sectional housing for the transmission supports an eccentrically mounted hydraulic pump which can be rotated to a plurality of positions.

Abstract: A seat suspension system, which includes a height adjustment valve for positioning a seat at a desired height in response to manual positioning of a height adjustment lever by controlling the amount of hydraulic fluid supplied to a cylinder having a piston therein coupled to the seat, provides damping of vertical motion of the seat by an accumulator coupled to the cylinder via a conduit so as to receive the hydraulic fluid from the cylinder and two different valves disposed in the conduit. A manually adjustable flow control valve has an adjustable orifice within the conduit for providing the seat with a nominal amount of damping.

Abstract: A compactor device for large round bales is disclosed comprising a horizontally disposed cylindrical housing containing a plunger, a double toggle mechanism connected to the plunger, a hydraulic cylinder connected to the double toggle mechanism for driving the plunger, and a stabilizer linkage connected to the plunger and the double toggle mechanism for maintaining the plunger in a vertical position during compaction of a bale.
