REVERSING MOWER ROTATION OF SIDE AND

REAR HYDRAULIC FLAIL MOWERS

To reverse the rotation of the side and hydraulically driven rear flail, a dif ferent idler
arm is needed only for side flail. Part No. TF4346 is used in standard rotation. Part
No. TF4345 is used in reverse rotation.
When before attempting this procedure be sure all dirt is cleaned away from the
motor and around all hose connections. This is to prevent the oil from becoming
contaminated. 1-Start by removing the belt shield from the flail mower. 2-Remove the
locking and adjusting nut, spring washer and spring from the idler tensioning rod. 3-
Disconnect the tensioning rod from the idler arm. 4-Remove the idler arm with the
idler pulley attached. 5-Remove the idler pulley from the idler arm and reinstall on the
short end of the new idler arm.
Reinstall the idler arm and pivot pin. The pivot pin is installed into the hole in the
pivot bracket closest to the idler pulley. When assembling for standard cut
rotation, the idler arm is installed with the idler pulley toward the front of the mower
with the pivot pin in the front hole. When assembling for reverse rotation, with
smooth cut knives, the idler arm is installed with the idler pulley toward the rear of
the mower with the pivot pin in the rear hole.
