Blade Maintenance

Blade Safety

DANGER
A worn or damaged blade can break, and a piece
of the blade could be thrown at you or bystanders,
resulting in serious personal injury or death.
Trying to repair a damaged blade may result in
discontinued safety certification of the product.
• Inspect the blade periodically for wear or
damage.
• Never try to straighten a blade that is bent or
weld a broken or cracked blade.
• Replace a worn or damaged blade.
•
Use care when checking the blades. Wrap the blades or
wear gloves, and use caution when servicing the blades.
Only replace 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) (Figure 63) and measure height from table
to cutting edge of blade.
