Heavy Duty Post Hole Digger
The pto-driven digger is designed for 3-pt. mounting on a 60 hp or larger tractor and uses the weight of the tractor to apply up to 5,000 lbs. of downpressure for high speed drilling.
"It has a simple, clean design with no unnecessary components and sells for only about half as much as other drill-throughrock post hole diggers," says Harleman. "It can drill about 2 in. per minute in solid rock and will go as deep as 3 1/2 ft. A telescoping 18-in. extension can be used to drill a hole up to 5 ft. deep. By pulling a pin the gearbox and auger can be removed and a clevis pin installed on the frame, allowing it to be used as a hydraulic boom to posts."
A hydraulic-driven model equipped with two cylinders sells for $3,450. A single-cylinder, pto-driven model for small tractors sells for $1,575. Augers are available in 9 to 30-in. diameters. A 12-in. dia. auger sells for $910.
