Mower Deck Installation
4. Engage the deck carrier frame tube sockets
on the tractor support arms. Refer to Mower
Deck Installation photo for socket location.
Slide the deck onto the support arms approxi-
mately 3 in. (76 mm).
5. Reaching under the tractor, slide the PTO
coupler tube onto the tractor's PTO drive shaft.
Make sure the ring has "snapped" securely on
the spline shaft.
IMPORTANT: To prevent damage to the mow-
er, make sure the PTO quick disconnect is
securely locked on the tractor, with the locking
balls fully seated in the groove and the ring in
the locked position (refer to the Quick Dis-
connect Ring "Locked" Position illustra-
tion). After installation, pull on the PTO cou-
pler to check for security.

IMPORTANT: When installing the DS52 Mow-
er deck, make sure to retract the dolly wheel
after mounting the deck on the tractor.
6. Slide the deck the rest of the way on the deck
arms. If the deck is collection style (GHS
equipped model), the 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
helpful in fitting and guiding the deck chute
into the blower.
7. Install the hitch pin through the hole on the
end of each support arm to lock the deck in
place. Two (2) hitch pins are included in the
Owner's Packet of materials.
