## What is Tree Felling Cut Calculator?

About to drop a leaning tree and need to know your notch depth, hinge thickness, and whether the lean angle makes it too dangerous? This calculator gives you the numbers before you start the saw.

Enter tree DBH, height, lean angle, lean direction, desired fell direction, and wood type. Get precise felling parameters and a safety risk assessment instantly.

WHAT YOU GET:
- Notch depth range (min and max)
- Hinge thickness and width
- Back cut height guidance
- Lean correction angle
- Felling radius
- Safety risk level (low, moderate, high)
- Two escape routes based on fell direction

COMPASS ANALYSIS:
Compares lean direction against desired fell direction to calculate correction angle and risk level. Flags high-risk situations where lean opposes the fell.

WOOD TYPES:
Softwood and hardwood, each affecting hinge behavior.

Works completely offline. No account required. Built for loggers, arborists, and forestry workers who need safe, accurate felling parameters before every cut.
