So I finally got a chance to use my new post hole digger with my old Yanmar 1500 tractor. I checked that the PTO turned and turned the gearbox and auger after I installed it so I thought I was good to go. However, when I started the first post hole, as soon as it barely made contact with the ground, the auger bit stopped turning. The tractor throttle was all the way high. I tried this in PTO speed 1 and 2, with same results. I would have tried the 3rd speed but I have never been able to get it in speed 3.
Any ideas as to why it does this? Is the PTO shot? I changed out the transmission/hydraulic fluid (with new filter) so the hydraulics should be good!
