Design Change Improves Performance Of Tree Shear WOODLOT EQUIPMENT Miscellaneous 28-3-35 One problem with hydraulic tree shears is that as soon as you start cutting into the tree, you have to keep applying forward pressure to keep the blades from slipping back off the tree. To solve that problem, Sidney Mfg. modified its Timberline Tree Shear by adding teeth to the stationary side of the shear.
"Cutting a 14-in. dia. tree in one cut is like trying to cut a dowel with a pair of scissors," says Mike Blackburn, sales manager for Sidney Manufacturing, who points out that having to apply continuous forward pressure also saps power from the machine.
The teeth added to the Sidney shear dig into the trunk as the blade begins to close, preventing slippage.
The shear rotates 90 degrees for vertical splitting so the teeth also help hold felled trees for further cutting or moving them.
Sidney's modified tree shear sells for $5,288.
