BLADE CARRIER REMOVAL/INSTALLATION
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, and PTO disengaged and
the cutter blocked in the raised position.
BLADE CARRIER REMOVAL
Remove cotter pin and loosen slotted nut on gearbox shaft. Loosen but do not remove the nut until the blade
carrier is loosened. Use a suitable 2 jaw gear puller to pull carrier off tapered gearbox shaft. If gear puller is not
available use long bar inserted through blade bolt access hole with end against rotor bar. Strike opposite end of
bar with sledge hammer. Rotate blade carrier 180 degrees and repeat process until carrier breaks loose.
BLADE CARRIER INSPECTION
Blade bolt fit into blade bar should be checked every time blades are changed. The blade bolt should fit into
bar as a snug slip fit. If the blade bolt fit appears to be loose or sloppy, measure the hole in bar. If the bottom of
the hole is 1/16 or greater than the diameter of the new blade bolt, the blade carrier should be replaced.
Bushings can be removed by cutting bushing head where it is welded to carrier bar. Once head is removed,
bushing can be pressed out of bar. Clean and grind top of blade bar so new bushing can be installed and
welded. Bushing should be pressed into bar as far as possible. Use low hydrogen rod to weld bushing in place.
Failure to replace worn blade carriers as described above may lead to catastrophic failure
of the blade, blade bolt, and/or blade bolt nut; resulting in the ejection of the broken parts
out from under the mower at tremendous speed and force which could result in serious
bodily injuy or death.
