Blade Safety
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.
-
Inspect the blades periodically for wear or damage.
-
Use care when checking the blades. Wrap the blade or wear gloves, and use caution when servicing the blades. Only replace or sharpen the blades; never straighten or weld them.
Before Inspecting or Servicing the Blades
-
Park the machine on a level surface and disengage the auxiliary hydraulics.
-
Shut off the engine, remove the key, and wait for all moving parts to stop before leaving the operating position.
-
Disconnect the attachment hydraulic couplers from the traction unit and connect the couplers together.
Inspecting the Blades
Maintenance Service Interval | Maintenance Procedure |
---|---|
Before each use or daily |
|
-
Inspect the cutting edges (Figure 8).
-
If the edges are not sharp or have nicks, remove and sharpen the blade; refer to Sharpening the Blades.
-
Inspect the blade.
-
If you notice any crack or wear, immediately install a new blade (Figure 8).
Replacing the Blades
Replace the blades if they hit a solid object, are out of balance, or are bent.
Important: Replace all the blades at the same time to maintain consistent wear and weight balance.
-
Loosen the 2 bolts securing the blade-access cover and move the cover out of the way (Figure 9).
-
Turn the flywheel until you see the blade nut. Remove the blade nut.
Note: The square neck on the bolt prevents the bolt from spinning. The blade will drop after you remove the nut.
-
With assistance from another person, install a new blade, nut, washer, and bolt (Figure 10).
Important: Use new hardware when installing a new blade.
-
Repeat the procedure for the other blades.
-
Close the access cover and tighten the bolts (Figure 9).
Sharpening the Blades
Remove the blades as described in Replacing the Blades and use a file to sharpen the cutting edge at the end of the blade (Figure 11).
Note: Maintain the original angle. Ensure the cutting edge is 0.8 to 1.6 mm (1/32 to 1/16 inch) thick.
Checking the Hydraulic Lines
Maintenance Service Interval | Maintenance Procedure |
---|---|
Before each use or daily |

Warning
Hydraulic fluid escaping under pressure can penetrate skin and cause injury. Fluid injected into the skin must be surgically removed within a few hours by a doctor familiar with this form of injury; otherwise, gangrene may result.
-
Keep your body and hands away from pinhole leaks or nozzles that eject high-pressure hydraulic fluid.
-
Use cardboard or paper to find hydraulic leaks; never use your hands.
Removing Debris
Maintenance Service Interval | Maintenance Procedure |
---|---|
Before each use or daily |
|
Every 50 hours |
|
Regular cleaning and washing increases the lifespan of the machine. Clean the machine directly after use.
Use care when using a high-pressure sprayer, because it can damage decals, the planetary, and the hydraulic system.
