"Jack Hammer" Post Pounder
 ✖  |
Fencing contractor Floyd Yoder of St. Ignatius, Mont., found a way to speed up his work by converting a hydraulic-operated, jack hammer-type concrete breaker into a skid loader-mounted post pounder that works like a rapid fire pile driver. He’s now manufacturing units for sale.
The post pounder weighs about one ton and is driven by a hydraulic motor that operates off the skids loader’s hydraulics. A steel cup on the bottom fits over the top of the post so it can’t move or deflect sideways. Yoder uses his Gehl 7810, 100 hp skid loader to operate the unit.
“It’s designed and made by a fencer for the serious fencer,” says Yoder. “I can drive two posts per minute in a perfectly straight line, and with perfect safety to the operator. I have a local post mill sharpen the posts to a pencil point and then round off the corners so the post won’t split. The driver applies 1,000 ft. lbs. of down pressure on the post.
“Another advantage is that it’s much easier to put on or take off than conventional skid loader-mounted units. All I do is release the quick-tach and a pair of hoses. That way I can use the same skid loader for other jobs such as pulling out old fence posts, mowing brush, and so on.”
Yoder bought the concrete breaker, which was originally designed to mount on an excavator and came with a chisel point, from a local equipment dealer. A machinist cut off the chisel point and replaced it with the big cup. He also made a 3/4-in. thick steel, quick-tach mounting plate that supports the unit from both sides instead of the top, allowing it to be raised up to 10 ft. high.
“The increased height lets me pound 12-ft. tall posts into the ground,” says Yoder. “I’ve also used it to drive steel pipe posts, but most of the time I use it on treated wood posts up to 8 in. in diameter.
“My Gehl 7810 is 8 ft. wide so it’s really stable on steep ground. I made it even more stable by mounting big 46-in. high, 16-in. wide wheels – originally designed for semi tractors – on the skid loader with a lot more clearance over stumps and rocks.”
A chain hanging from the post driver helps him keep posts plumb. “The chain also serves as a depth gauge, because as soon as the chain hits the ground I know all the posts are at same depth. I can also use the chain to pull out the post if it breaks or won’t go down into the ground.”
Yoder offers the post pounder in 3 different sizes, which apply 500, 750, and 1,000 ft. lbs. of down pressure. Prices start at $10,500. Yoder is looking for dealers.
