The Back Cut » The Humbolt Back Cut The back cut disconnects almost all of the tree from the stump leaving a hinge that helps to control the tree's fall.
This is because in Humboldt cutting, as opposed to the conventional method, the notch is made into the stump rather than the log, which reduces the loss of useable wood.
Humboldt Notch
Using full throttle and entering horizontally, cut inwards to approximately 25% of the diameter of the tree. Next, create your Humboldt cut by cutting upwards at a 45-degree angle until you meet the uppercut. Make sure you don't overcut or go too deep, they should line up perfectly.
Open-face notch, aiming with top cut. This is the cut we recommend for most trees on flat or slightly sloping terrain. It's safe and the easiest method to get right. The large opening angle (60-80°), ensures that the hinge remains intact until just before the tree hits the ground.
An undercut must be made in each tree being felled. The undercut must be of a size so the tree will not split and will fall in the intended direction.
Dutchman. The seat that interferes with the smooth closing of the notch. Caused when one of the notch cuts is made too deep and extends beyond the endpoint of the other notch cut, known as "Bypass".
When cutting up a felled tree, avoid touching the ground with the chain because even a brief encounter will severely dull the cutting teeth on your chain saw. If possible, cut partially through the tree and then rotate it to cut the rest of the way through.
Why Put a Notch into a Tree? Notches are used to help a tree fall in your chosen direction. By removing a small notch out of the trunk and creating a hinge, you prevent the tree from falling in any direction, and instead, force it to land where you want it to. Think of it this way.
They are the conventional notch, Humboldt notch, and the open-face notch. Each has distinct advantages, disadvantages, and uses, and in this article we will cover all three as well as our recommendation for the best style.
6 The depth of the notch should be 1/3 of the tree diameter. The face opening of a notch “A” should be equal to the depth of “B”. An open face notch is safest and requires an opening of 70% or more to prevent premature closing of the notch.
A barber chair occurs when a tree being felled delaminates vertically before the hinge is cut thin enough to bend. The term refers to the sliding action of the old style barber chair that positioned patrons in a head down, feet up position so the barber could more easily shave with the straight razor.
The remaining trees will carry on growing and produce a good quality timber crop. Thinning also lets more light in to the forest floor, which increases the diversity of plants in our woodlands and encourages more wildlife.
Best done about a month before buds open, which for apples and pears is right about now.
Do Trees Grow Back After Being Cut Down. Yes, they can. That's why it's essential to be knowledgeable about tree growth when you need to remove one permanently. When this survival mechanism is triggered, single, or multiple sprouts may appear.
According to The International Society of Arboriculture, the most common reason given for topping is to reduce the size of a tree, either because it has become too large for the property or a perception that it may pose a hazard.
Making the Cuts » Special Techniques for Felling Difficult Trees. A large tree may be felled against its natural lean by inserting one or more wedges in the back cut. As the back cut is sawn, the wedges are driven in with an axe.
What is a tree crown lift? A crown lift is the pruning technique of removing lower branches on a mature tree which lifts the canopy or crown of the tree.
Bucking a tree
A sawbuck is useful for safely cutting wood to length. The process of cutting a tree into usable lengths is called bucking. Bucking often occurs as a tree is being limbed, such as when the limbs of the crown are to be used as firewood.
Kickback – the rapid upward motion ofh te guide bar that can occur when the saw chain, near the nose (tip) of the top area of the guide bar, contacts an object such as a log or branch (rotational kickback), or the backwardm otion that can occur when the wood closes in and pinches hte saw chain in the cut (pinch ...
