blade to be lowered a larger distance from the neutral position before the blade is pitched forward the dump auto settings may be set in the same manner outlined above in the operation described above a bulldozer is able to be used to push material to a dump site according to another operational task a bulldozer may be required to operate on a downwardly or upwardly inclined slope fig9 10 11 12 13 14 and 15 show how a bulldozer with a bucket according to the first preferred embodiment may be operated so as to control the orientation of the bucket as the bulldozer moves forward thus as shown in fig9 the bulldozer 70 with a bucket 71 is operated so that the onboard processor uses the auto pitch feature to follow the contour of the ground surface thus in fig1 the blade 71 is pitched tilted forwardly using tilting pistons 72 after a slight lifting of the blade 71 by operation of arms 73 and lifting pistons 74 in fig1 the bulldozer 70 moves forward and the blade moves downwardly first under operation of pistons 74 and 72 and arms 73 as a result the blade 71 has an initial forward pitch as the dozer starts to dig and after the dozer follows the blade into the inclined area as shown in fig1 the blade is returned to its neutral position again by operation of pistons 72 to 74 and arms 73 after the dozer is following the incline downwardly the blade 71 is loaded with material and the.
