Base equipment side-slicer knives or optional smooth-cut knives available
Side-slicer knives
Base equipment side-slicer knives are good all-purpose knives. They provide aggressive cutting action in tough conditions.
The side-slicer knife characteristics are as follows:
- Knives are made of heat-treated alloy steel for durability.
- Individual knife weight, along with the centrifugal force created, provides an aggressive cutting action.
- Edges are ground to provide a sharp cutting surface and reduced horsepower requirements.
Rotor
Smooth-cut knives can be ordered as an option:
- Smooth-cut knives utilize the same mountings as the side-slicer knives.
- These optional knives are good for grassy, weedy conditions and are self-cleaning.
- Knives can also be resharpened for added wear life.
