Incorrect Backcutting
Incorrect Backcutting
The OSHA standard requires that the backcut be made above the notch when the face cut is horizontal.  This will create a ledge to keep the log from sliding back across the stump.
Kinds of Incorrect Back Cuts:
Back cut at the same level as a notch
samelevel1
Highly increases the possibility of the tree butt kicking-back off the stump and decreases elasticity of the hinge.
Back cut too deep
toodeep1
The hinge will break almost immediately resulting in inaccurate felling, and damage to the bar or saw.
Back cut too high above the notch
toohigh1
Highly increases the necessity of pushing or pulling the tree to make it fall; produces low quality butt and also decreases the effectiveness of the notch.
Back cut below the notch
below1
Highly increases the possibility of the tree sitting back on the stump; produces a low quality butt and also may require pushing.
Sloping back cut
sloping1
Lessens the chance of meeting the notch or leaves an inaccurate hinge, producing a low quality butt and wasted material.
Angle back cut with inadequate notch
angle1
Decreased possibility of meeting the notch produces a poor-quality hinge, loss of felling control and a low quality butt.
