When using my Hydraulic Earth Drill, the auger turns fine in one direction, but does not turn or turns very slowly in the other direction. When I touch the auger to the ground it stops. What’s wrong?
Most likely your valve control linkage is bent. This is the small rod that connects the control to the valve spool. Straighten it out, and then make sure that the flat part of the lever (the part you pull or push with your fingers) does not touch the handlebar at any time.
