7. DRIVELINE ATTACHMENT
6.2 Setting Deck Pitch
To facilitate safe and efficient operation, the mower
should be operated with the deck approximately 3/4”
LOWER IN THE FRONT THAN THE REAR.
Operating the mower at this pitch will allow the mower
to cut the grass only once and requires less work from
the tractor. In addition, a more even distribution of
the clippings from the rear of the mower will be
achieved with this deck pitch.
LEVELING WING SECTIONS WITH CENTER
1. To level the wing sections with the deck center,
adjust the leveling screw between the wing axle
and the center axle. To lower the wing, loosen
the jamnut and shorten the screw assembly,
lengthen the screw assembly to raise the wing.
After wings are leveled, retighten jamnuts to
maintain settings.
The driveline yoke and tractor PTO shaft must be dirt
free and greased for attachment.
To connect the mower driveline to the tractor PTO
output shaft, pull the driveline yoke collar back and
align the grooves and splines of the yoke with those
of the PTO shaft. Push the driveline yoke onto the
PTO shaft, release the locking collar, and position the
yoke until the locking collar balls are seated onto the
PTO shaft. Push and pull the driveline back and forth
several times to ensure a secure attachment.
WARNING!
When attaching the PTO yoke to the Tractor PTO shaft, it is important that the spring
activated locking collar slides freely and the locking balls are seated securely in the groove
of the PTO shaft. A driveline not attached correctly to the Tractor PTO shaft could slip off
and result in personal injury and damage to the cutter.
1. Adjust the leveling rods linking the tongue to the rear axle until the front of the mower is at least 3/4” lower
in the front that than the rear. To lower the front, lengthen the leveling rods and to raise the front shorten the
leveling rods. IMPORTANT: Adjust the leveling rods the same amount and maintain equal tension in the
rods. Improper adjustment may cause rods to snap or bend. Retighten the jamnuts after the deck pitch has
been set.
