Trying to find a pdf copy of the l5450 owners/operators manual free if possible to understand the correct operation of the draft control. Familiar with other brands first Kubota rebuild. Have the service and parts manual however the tractor wasn't going prior to rebuilding and an not sure how the system is designed to operate. The valve body and all linkages had to be removed from the 3pt linkage cover, the raise and lower control works correctly, moving the draft control lever has little effect. Suspect incorrect assembly, prior to removing the 3pt linkage unit, the service manual describes adjustments to the draft linkages has anyone found that these could make that much difference?
