Tractor-Mounted Pto-Driven Trencher

Tractor-Mounted Pto-Driven Trencher TILING MACHINES Tiling Machines 19-5-23 "To our knowledge, there's no chain trencher on the market designed to fit on farm tractors," says Roger Giasson, who operates a welding and repair shop in Saskatoon, Sask., and has started building and selling a heavy-duty tractor-mounted ptodriven chain trencher. Designed to mount on any Cat I or II 3-pt. hitch, the heavy-built trencher digs down to a depth of 45 in. The heavy digging chain will pull out rocks up to 10 in. in size but is shear bolt protected in case it hits anything larger. Giasson built it for his own use and then started doing custom work with it. "Customers were so pleased with the aggressive digging ability of the machine that we decided to build them for sale. They'd be ideal for any farmer who wanted to do custom work on the side, or for small towns, contractors, and anyone else who already has a tractor and needs a high-capacity digger," says Giasson. He drives the unit with a 9-in. Ford automotive rear end that was narrowed up on both sides. A #80 sprocket mounts on one end. A drive chain runs from the sprocket to a 9-tooth sprocket down below - made from wear resistant plate - that drives the digging chain. A 16-in. dia. auger on this main drive shaft carries dirt away from the sides of the trench as it's dug. The digger is pivoted up and down by a 4-in. dia. hydraulic cylinder controlled from the tractor seat. Bolt tighteners are used the tighten the chain as it wears. "It's built as heavy as even the most ex-pensive trenchers on the market," says Giasson, noting that production machines are fitted with heavy duty gearboxes. Sells for $8,995 (Canadian).
