- 620 John Deere, (1) 318 JD, 425 AWS JD, 4500 JD
I have a 620 John Deere with a Bush Hog 3pt hitch log splitter. The splitter works generally well until I get into some big oak. Then the hydraulic squeals on the tractor and I have to knock the wood off the splitter wedge. I've been told the cylinder is big enough but the pressure relief valve on the tractor is releasing. Has anyone ever shimmed up the pressure relief valve on a '58-59 620 John Deere? I have a repair manual but was hoping someone had done it before.
