Servicing the Cutting
Blades
Blade Safety
•
Inspect the blade periodically for wear or damage.
•
Use care when checking the blades. Wrap the
blades or wear gloves, and use caution when
servicing the blades. Only replace or sharpen the
blades; never straighten or weld them.
•
On multi-bladed machines, take care as rotating 1
blade can cause other blades to rotate.
Servicing the Blade Plane
The rotary deck comes from the factory preset at 5
cm (2 inches) height of cut and blade rake of 7.9 mm
(0.310 inch). The left and right heights are also preset
to within ± 0.7 mm (0.030 inch) of the other.
The cutting deck is designed to withstand blade
impacts without deformation of the chamber. If a solid
object is struck, inspect the blade for damage and the
blade plane for accuracy.
Inspecting the Blade Plane
1. Remove the hydraulic motor from the cutting
deck and remove the cutting deck from the
tractor.
2. Use a hoist (or minimum of 2 people) and place
the cutting deck on a flat table.
3. Mark 1 end of the blade with a paint pen or
marker. Use this end of the blade to check all
heights.
4. Position the cutting edge of the marked end of
the blade at 12 o'clock (straight ahead in the
direction of mowing)
height from table to cutting edge of blade.
