Abstract: A seal (16) has a body (38), a leg (40) and first and second sealing areas (42,44). The seal (16) is used in a seal assembly (10) having first and second members (12,14), such as, for example, a frame portion (20) and steering knuckle (27) of a work vehicle. Apparatus (28) such as bearing (30) supports the knuckle (27) in rotation relative to a king pin (24) of the frame portion (20). Foreign matter can enter between the frame portion (20) and steering knuckle (27) and interfere with vehicle steering. In the assemly (10), the sealing surfaces (42,44) contact substantially perpendicular surfaces (32,34) of the frame portion (20) to block passage of foreign matter to the bearing (30). A second end portion (54) of the seal leg (40) can be controllably deflectable in order to permit overfill of lubricant to pass from the bearing cavity between the frame portion (20) and steering knuckle (27).

Abstract: A combined control system for simultaneously control-line a vehicle throttle and transmission from a single pedal wherein the control pedal is mounted for fore and aft rocking movement with transmission linkage means connected thereto for movement therewith for controlling forward and reverse of the transmission. Linkage means for the throttle includes a pair of bell cranks mounted fore and aft of the pivot axis of the control pedal whereby one bell crank is engaged by the pedal when rocked in one direction and the other bell crank is engaged by the pedal when rocked in the opposite direction with the bell cranks connected together and to the throttle linkage means so that either direction of rocking of the control pedal imparts a movement in the same direction through one or the other of the bell cranks to the throttle control linkage.
