Add powerful hydraulic down-pressure to your BEFCO Mole digging setup for greater performance in hard soils.
The Hydraulic Down-Force Kit for the BEFCO Mole 300 & Mole 400 post-hole diggers is a rugged add-on designed to significantly boost digging power — especially in tough, compacted or rocky soil. By harnessing your tractor’s hydraulic system, it applies an extra downward force to help drive the auger deeper and more effectively, reducing strain on the drivetrain and improving hole consistency.
This kit is ideal for anyone using a Mole 300-512 or 400-512 model on projects like setting fence posts, planting trees, installing poles, or other jobs requiring deep, clean holes in challenging ground. It’s especially useful if you frequently encounter clay, heavy soil, or terrain where standard auger pressure isn’t enough.
Installation is straightforward: the kit mounts to the digger’s boom and yoke using supplied brackets and pins, integrating with your tractor’s hydraulics so you get extra digging force — between roughly 300 and 500 lb of added down-pressure depending on mounting configuration.
Enhanced Digging Force
The kit uses a hydraulic cylinder to add 300–500 lb of downward pressure — giving your auger extra drive to penetrate hard or compact soil with less effort on the tractor’s PTO or gearbox.
Easy Tractor Integration
Designed to attach directly to the digger’s boom and yoke, the kit integrates with the tractor’s hydraulic system for seamless operation — no complex modifications needed.
Improved Efficiency in Tough Soil
With added down-pressure, the auger reaches full depth faster and with more consistency, reducing time and fuel used per hole — especially valuable in rocky, clay-rich, or compacted ground.
Compatibility & Reliability
Specifically designed for Mole 300-512 and 400-512 models, this kit works with their reinforced boom and heavy-duty gearbox — ensuring robust, long-term performance even under heavy loads.
