3-point hitch on 360 Flail Mower
3-point hitch on 370 and 390 Flail Mowers
All machines have a Category 2/1 3-point hitch. Bushings or reversible pins are included for Category 2/1 compatibility.
The 360, 370, and 390 Mowers with centrally mounted hitches are suited for normal cutting conditions:
- 360 Mower is compatible with quick-coupler Category 1 only.
-
370 and 390 Mowers are compatible with quick-coupler Category 1 and 2.
The 390 Mower with a 30.5-cm or 66-cm (12-in. or 26-in.) hitch offset to the right is ideal for trimming along walls, buildings, trees with low-lying branches, fences, or orchards.
Heavy-duty hood and end plates
Heavy-duty hood and end plates
The hood and end plates are designed for heavy-duty applications:
- Hood is made of 0.48-cm (0.188-in.) thick steel to resist denting and wear.
- End plates are made of 0.64-cm (0.250-in.) thick steel to provide structural support and resistance to side thrusts.
- Full-length torque tube helps prevent twisting when operating on uneven ground.
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.
