Abstract: A vehicle having an engine speed regulator, an operator's platform, a bulkhead forward of the platform, and a speed regulator including a positionable hand lever and spaced apart foot pedals operable to override the speed determined by the hand lever without affecting movement of the hand lever. The hand lever, the spaced apart foot pedals and the linkage structure interconnecting the various controls are disposed entirely above the platform and behind the bulkhead.

Abstract: A valve control mechanism for operating a plurality of valves in a bank of valves which can be selectively operated by interchangeable lever arrangements one of which has a separate lever for each valve and another of which has a single lever for a pair of valves. The bank of valves and the lever arrangements are detachably removable independently of each other to permit easy servicing and selecting of the desired lever arrangement or to change the sequence of valve operation.

Abstract: A mobile planter of the pneumatic type which has a rotating drum with seed receiving apertures arranged so that seed is deposited at an upper peripheral surface of the drum to be received in the seed receiving apertures. The exterior of the drum is maintained at a higher pressure than the interior of the drum so that the resultant pressure differential holds seeds in the apertures until they are released from the drum at the lowest point in the path of travel of the drum surface from which the seeds are conveyed by tubes utilizing the pressure at the exterior of the drum for deposit in the ground.

Abstract: A control system for a tractor vehicle having an operators station resiliently mounted relative to the chassis in which the control system passes through a wall of the operators station and incorporates mounting means acting to support the control system to accommodate relative movement between the operators station and chassis and also to act as a seal to prevent passage of dust and dirt to the operators station and in addition, to act as a suspension supporting the control system in a manner for dampening vibration and noise which otherwise would be transmitted through the control system to the operators station.

Abstract: An exhaust system for off the road vehicles of the type incorporating a roll-over protection structure for protecting the operator's station on the vehicle in which the exhaust system is incorporated within a housing forming a part of the protection structure.

Abstract: A single lever control for actuating a pair of adjacent mechanisms such as valves spools in which a pair of actuating arms are supported for pivotal movement about intersecting axes and in which a control lever is supported for universal movement about the intersection of the axes for transmitting movement to both or to a selected one of the actuating arms.

Abstract: Stabilizing apparatus for vehicles supporting load handling equipment such as tractors mounted with backhoes in which the stabilizing apparatus is movable vertically from a transport position to a ground engaging position and also may be moved horizontally to vary the angular disposition of the stabilizers relative to the vehicle to engage the ground at longitudinally spaced positions.

Abstract: Stabilizer apparatus for use with a vehicle such as a tractor supporting load handling equipment such as a backhoe in which foot members disposed at opposite sides of a vehicle are engageable with the ground to stabilize the vehicle and are movable to an elevated position for transport by the vehicle. In the ground engaging position the foot members are positioned with their outer extremities projecting beyond some maximum predetermined width of the vehicle and in their transport position occupy a position in which the outer extremities are disposed within the confines of the maximum predetermined width of the vehicle.

Abstract: A seat for mobile material handling equipment which is movable between two different seating positions about a horizontal, transverse axis and is provided with a lock mechanism which securely holds the seat in either of its two positions.

Abstract: An automatic height control for the header of a combine in which the elevation of the header relative to the ground is varied by hydraulic means under the control of the system using the presence or absence of light to lower or raise the header, the light being regulated by feeler members engageable with the ground and being responsive to changes in ground contour.

Abstract: Backhoe swing apparatus including a backhoe swing bracket for supporting a backhoe for side-to-side swinging movement. A pair of hydraulic actuators are connected with the swing bracket for actuating the swing bracket in opposite directions. The hydraulic actuators are of the piston and cylinder type, and are controlled by a hydraulic system including a pair of hydraulic lines for conducting hydraulic fluid to and from each of the hydraulic actuators. A normally open pressure reducing valve in one of the hydraulic lines is operable to control pressure to one of the actuators to actuate the swing bracket in one direction and to thereby limit the pressure of fluid flowing to the actuator. Simultaneously, flow from the other actuator through the other hydraulic line is controlled by a first normally closed metering valve, which opens a permit such flow only when a predetermined minimum pressure exists in the other hydraulic line.

Abstract: A seed planting device wherein seeds are carried at high velocities from a central selecting and dispensing unit to individual row units, each row unit has a rotating device that positively decelerates the seeds sufficiently to avoid bouncing of the seeds when they engage the ground and at the same time avoids materially changing the spaced relation between the seeds.

Abstract: This specification describes a mechanism for clamping an air filter in a vehicle by a floating lever which is actuated by a cranked rod, spring mounted on the vehicle. The spring exerts a clamping force against filter and floating lever ensures force is evenly applied.

Abstract: This specification discloses a transmission clutch brake for use in a torque delivery gear system. A rotatable clutch disc driven by an input shaft and selectively engageable by a pressure plate carries a pair of plates. The plates embrace a brake plate carrying friction material on opposite faces thereof. Upon disengagement of the pressure disc from the clutch plate one of said plates of said pair is moved axially relative to the other thereof in a clamping manner to grip the brake plate against rotation. The latter brake plate is connected to a stationary splined hub utilizing a snap ring. The ring acts as a torsion spring and permits limited slight rotation of the brake plate and clutch disc clamped thereto as well as the input shaft to facilitate meshing of gears of the transmission.

Abstract: This specification describes a multiple throw selector apparatus for use in change speed gearing which includes speed ratio shift rails to engage synchronized clutches and a range lever which engages an unsynchronized clutch. The range shift rail is moved between its various operative positions directly by a selector member. The ratio shift rails are actuated by the selector member through a pivoted link thereby increasing mechanism advantage between control lever and ratio shift rails.

Abstract: A movable seat assembly which is supported relative to a vehicle by means of a support which permits the seat to be faced in opposite directions and in which the seat is pivotally mounted relative to the support to be disposed in selected positions of adjustment in either of its two facing directions and including a latch mechanism which securely locks the seat in either of its two facing directions or in its selected positions in a manner resisting loads placed on the seat and tending to cause pivotal movement of the seat or its support.

Abstract: Two transmission shift levers are pivotally movable, one universally and the other about a single axis, by respective control members operative thereon through concentric shafts, the shaft associated with the universally pivotable lever being axially slidable relative to the shaft associated with the other lever in response to translational movement of its control member.
