“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.
