About this product
Heavy-Duty Post Hole Digger for Tractors (18–50 HP)
Dependable digging power for fences, trees, and posts — built to tackle heavy-duty soil work with ease.
The BEFCO Mole 300-512 Post Hole Digger is a rugged, tractor-mounted auger system designed to simplify hole digging for posts, fences, tree installations, and other landscaping or agricultural projects. It’s built for tractors with 18–50 HP and supports Cat. 1 & 2 3-point hitch systems, making it a versatile choice for small to mid-sized tractors.
Thanks to its reinforced boom, heavy-duty yoke, and dependable gearbox operating at 540 rpm, this post hole digger delivers consistent torque for smooth, efficient digging — even in tough or compacted ground.
With a wide range of auger sizes (from 6″ up to 30″ diameter) and auger lengths of 36″ or 48″, this unit can handle everything from small fence-post holes to the large holes needed for trees or bigger posts. Augers feature fully welded flighting and replaceable knives and point for long-lasting performance.
