MAINTENANCE
REPLACING CUTTERS (Fig. 9)
Remember before you replace any cutters you must turn the engine off, wait for moving
parts to stop, remove the key from the ignition and remove wires from spark plugs.
1. Put the handle in the transport position and tilt the Stumper all the way back until it rests
firmly on the ground.
2. To make cutter replacement easier, you can slide tensioner wrench handle through the hole in
the cutter guard and cutter wheel. This will prevent the wheel from turning during blade
replacement.
3. Loosen the allen head bolts (16262) from each of the cutter pockets and remove the cutters.
4. Install the new cutters in pairs alternating the cutters as shown.
5. Tighten the allen head bolts only tight enough to hold the cutters in the pockets, make sure all
of the cutters are extended past the cutter wheel equally. (Fig. 10)
6. Torque each allen head bolt to 175 ft. lbs. (alternating as you tighten) to lock the cutters in the
pockets.
7. Once you have installed all of the cutters, double check to make sure all the allen head
bolts have been tightened securely and make sure all the cutters are equally extended. NOTE:
cutter wheel viewed from bottom of stumper. (Fig. 9)
Important Note: Do not operate the Stumper if any of the cutters are missing. This will
cause the cutter wheel to be out of balance. Also, make sure all of the pockets are the same
kind.
