Build fences, install posts, plant trees, and tackle demanding property projects with the AGKNX Model 1500 Heavy-Duty 3-Point Post Hole Digger. Designed for Category 1 and Category 2 tractors, this PTO-driven implement is rated for tractors up to 75 HP and built for dependable digging in demanding farm, ranch, and land-maintenance applications.

Its four-position adjustment system helps improve tractor fitment and digging alignment, while the 2-inch output shaft provides a secure connection for compatible heavy-duty augers.
