4. Reaching under the tractor, join the PTO tube to
the PTO shaft (align arrow decals). Slide the
PTO tube onto the spline shaft on the tractor
PTO gearbox.

mounting the deck on the tractor.

5. Slide the deck the rest of the way on the deck
arms. If the deck is rear discharge (GHS
equipped model), the rear discharge chute will
need to be aligned and connected to the blower
inlet during the last 2 in. (51 mm) of slide action
on the support arms.
NOTE: Raising the mower body may be help-
ful in fitting and guiding the deck chute into the
blower.
6. Install the hitch pin through the hole on the end
of each support arm to lock the deck in place
(refer to Deck Counterweight Spring Installa-
tion photo). Two (2) hitch pins are included in
the owner's packet of materials.
7. Remove Installation Tool from coupler ring and
make sure the ring has "snapped" securely on
the spline shaft.
IMPORTANT: DO NOT operate tractor with
Quick-Coupler Installation Tool installed.
IMPORTANT: To prevent damage to the
mower, make sure the PTO shaft assembly is
securely locked on the tractor, with the locking
balls fully seated in the groove and the ring in the
full forward position (refer to the Coupler Ring
"Locked" Position photo). After installation,
pull on the shaft to check for security.

8. Raise the mower body (instead of lifting the
front of deck) and clip the counterweight springs
to the receptacle on front of body. Lower the
body to tension the springs. (Refer to Deck
Counterweight Spring Installation Photo.)
9. With the counterweight springs connected, the
weight on the deck caster wheels should be
15 to 25 Ib (6.8 to 11.3 kg). Check this weight
by lifting on the front of the deck carrier frame. If
required, the spring tension can be adjusted by
tightening or loosening the elastic stop nuts
located underneath the lower spring hook.

tion photo.
