Self-Propelled Post Pounder
 ✖  |
Friesen's post pounder/drill is built on the frame of a Timber Toter log skidder. It's powered by the skidder's original 453 cu. in. GM diesel engine but Friesen converted it to hydrostatic drive for greater maneuverability. He used 10,000 Series Charlyn hydrostatic motors mounted in place of the differential to chain drive the machine's axles, wheels and planetary gears. He completely rebuilt the frame of the machine to accommodate a 5-ft. wide by 10-ft. long steel deck on front for carrying posts. The main frame is built out of 10-in. dia. pipe, which doubles as a 50-gal. reservoir for water to use when drilling through rock or hard ground.
A pounder and drill mount at the back of the machine on a 12-ft. high mast that Friesen made out of 1/4-in. plate.
The pounder is housed in a steel housing measuring 13 in. wide by 10 in. deep by 32 in. high. It has three hammers at different heights timed by hydraulic gears on the top and bottom and driven by a hydraulic motor. They're all synchronized to swing together at the same time. Each hammer shaft is fitted with a 40-lb. steel weight.
The drill is custom-built from 9 ft. of 12-in. dia. commercial flighting and is direct driven by a 10,000 Series Charlyn hydraulic motor mounted inside the mast.
The pounder and drill are powered by a two-section, 60 gpm hydraulic pump mounted on back of the diesel engine. An-other pump mounted on the engine operates backward, forward and sideways tilt, as well as horizontal adjustment up to 5 ft. left or right.
"I built the machine six years ago and have put in 25,000 game fence posts measuring 5 to 8 in. in dia. and up to 16 ft. tall with it," Friesen says. "I've put in as many as 360 posts in a six hour day."
