Blade Removal - Schulte FX-1800 Operator's Manual

BLADE SHARPENING
Always sharpen both blades at same time to maintain balance. Follow original sharpening pattern as shown in
FIGURE Mnt-R-0008. Always sharpen blades by grinding. DO NOT heat and pound out edge. Do not sharpen
blade to a razor edge, but leave a 1/16" blunt edge. Do not sharpen back side of blade.
IMPORTANT: When sharpening blades, grind each blade the same amount to maintain balance. The
difference in blade weights should not exceed 1 ounce. Unbalanced blades will cause excessive vibration
which can damage gear box bearings. Vibration may also cause structural cracks in cutter housing.
Never work under equipment supported by a hydraulic device because it may drop if the
control is actuated (even with the engine stopped) or in the event of hose failure, etc. Always
use a secure support for equipment which must be serviced while in the raised position.
NOTE: Replace Blades in pairs after no more than 1/2" notch wear!

BLADE REMOVAL

To remove blades for sharpening or replacement,
remove the cover plate on deck of cutter near gear
box. Remove lock nut from blade bolt. NOTE:
Inspect lock nut after removal and replace if threads
are damaged. Always replace nut when replacing
blade bolt. When installing blades be sure and
check blade bolt pivot diameter for wear. Replace
bolt if worn more than 1/4 inch at any point. See
Figure Mnt-R-0014. Install blade bolts with partially
worn side of bolt either toward or away from center.
Tighten lock nut to 600 ft. lbs.
Avoid personal injury. Blade and/or blade carrier removal should be done only with the
tractor engine shut off, key removed, in neutral, parking brake on, PTO disengaged, and the
cutter blocked in the raised position.
