<p>An earth working vehicle such as a backhoe having an earth working bucket to form an excavation in the ground at the rear end of the vehicle and the operator must visually observe the excavation being done, a tiltable seat assembly including a seat support frame, an operator's seat secured to said frame, a resilient support for supporting said seat on said frame, a pivot support for pivotally connecting the support frame about a transverse horizontal axis to the vehicle to permit the support frame, the seat and the resilient support to tilt as a unit about the transverse axis and consequently tilt an operator in the seat for better visibility of the area being excavated. A vehicle seat assembly including a seat having a front edge and a seat pan for supporting the seat, a seat rake adjustment located beneath the pan and the front edge for vertically adjusting the latter relative to the rest of the seat; the adjustment means comprises a bracket secured to the underside of said pan and having a plurality of notches therein, a generally vertically extending hook latch having a hook at its lower end for swingably mounting said latch on the seat assembly, the latch having an upper end selectively engageable in the notches, an operator handle having an upper end and a lower end and pivotally mounted intermediate its length on the assembly, the handle upper end being secured to the seat front edge for manipulation by the operator to adjust the height of the seat edge, the lower end of said handle being engageable with the latch to shift the latch out of engagement with the notches when the operator pushes downwardly on the front edge of the seat.</p> |
