- The hydraulic down pressure kit allows for additional digging force in hard soil
conditions. The kit consists of a cylinder that attaches to the PHD-300 & 400 post hole diggers by the use
of mounting plates. It operates using the tractor hydraulic system and it provides
between 300 and 500 lb. of additional down pressure depending on mounting
configuration.

Chris Fallin –
Make sure your tractor hydraulics has a “float” position before you consider buying this downforce kit. My Deere 4052M has a Summit hydraulics rear remote with standard double-acting electronic solenoid valves. These solenoids are strictly “on/off” and therefore do not allow you to raise the post hole digger when the hydraulic cylinder is extended. The fix for me was to build a bypass circuit and plumb a simple, manual turn-valve across the “A” and “B” lines. Now when I raise the post hole digger I open the manual valve so the oil can flow between the cylinder lines.
