Loader-Mounted Tree Shear

Loader-Mounted Tree Shear TRACTORS Loaders “I used the legs off an old 2-ton feed bin to make a boom that’s fitted with a 20-in blade off an old walk-behind brush saw It lets me prune tree limbs up to 20 ft off the ground ” says 83-year-old Linus Schraner of Derby Ind     Schraner mounts the tree shear on his Allis Chalmers WD tractor Hoses run from an 11 1/2 gpm hydraulic pump mounted on the tractor’s pto up to a hydraulic motor located near the top of the boom The motor belt-drives a mandrel that Schraner fashioned from the rear axle off an old car     The boom clamps onto a steel frame that attaches to the loader arms and fits over a bale spear A big hydraulic cylinder is used to tilt the boom up or down     Schraner bolted the two 8-ft long feed bin legs together one turned over on top of the other He added another 2-ft section from another leg for added length “By pulling a pin from the bracket on the cylinder I can quickly remove the boom and use the bale spear to haul bales ” says Schraner     He mounted a valve on the tractor’s right fender to operate the tree shear     The saw’s V-belt pulleys provide extra speed with an 11-in pulley connected to the motor driving a 4-in pulley on the saw mandrel “I don’t have to run the tractor’s engine very fast in order to get a lot of speed on the saw ” he says     Schraner used the saw for the first time last summer to cut overhanging branches along the edges of a field and says it worked better than he expected “It works fast enough that I was able to make a mess pretty quickly cutting limbs off I was able to cut up to 6-in dia limbs in a single cut I have a good view and I can work in the comfort and safety of a tractor seat instead of having to climb up a ladder or stand in a loader bucket to reach overhanging branches     “The WD tractor is equipped with a hand clutch which works great with the saw because I can disengage the clutch and the pto will continue to operate which makes the saw easy to control ”     Schraner mounted a plexiglass shield in front of the steering wheel to keep wood chips from flying back on him The shield is clamped to a pair of thinwall metal pipes that slip over smaller 10-in long pipes that bolt onto the tractor’s frame             Contact: FARM SHOW Followup Linus D Schraner 11150 Urban Road Derby Ind 47525 ph 812 719-9721
