Sierra Post Hole Borer with Hydraulic downforce (No Auger)


Got Post holes to dig?  trees to plant?A Sierra PTO Post Hole borer with Downforce will help you dig holes with your tractor in the harder ground, making big jobs that much easier. It is designed to meet the applications of landscapers, lifestyle block owners, nurseries, and farmers.



-Shearbolt-protected 50 HP gearbox, with 2" output shaft gives you the wider choice of many auger manufacturers who use this almost industry standard 50mm size.

-Sierra has used a reinforced 100mm square steel tube boom.

-With Cat 1 and Cat 2 lower linkage holes, this machine will fit 18-100HP tractors.

-However, it does require a CAT 2 (25mm) top link pin to mount on the tractor.

-It comes with Category 2 lower pins supplied. 

-Sierra Post hole augers have replaceable hardened steel cutting tips, the most common replaceable tips available.

-A PTO shaft with a shear bolt yoke is included. When digging holes you know your tractor drive line is protected if you hit an unexpected obstacle.

- Your tractor requires 1 double-acting hydraulic circuit to control the hydraulic up and down of the post-hole digger. The 3-point linkage hydraulics must be in the float position and the auxiliary control used to lift the post-hole digger up and down to operate.
