Deck Installation
1. Lightly grease each deck support arm (2) on the
tractor. Refer to Mower Deck Installation photo
on next page for location of deck support arm.
2. Engage the deck carrier frame tube sockets on
the tractor support arms (refer to Discharge
Chute and PTO Shaft Guard Installation
photo for socket location). Slide the deck onto
the support arms: all the way if SD equipped
model, approximately 3 in. (76 mm) if GHS
equipped model.
NOTE: When installing the DSD52 or DSD62
Mower deck, make sure to retract the dolly
wheel after mounting the deck on the tractor.
3. If the deck is rear discharge (GHS equipped
model), the rear discharge chute will need to be
aligned and connected to the blower inlet dur-
ing 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.
4. 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.
5. Connect the mower deck PTO drive shaft
assembly to the tractor with the splined quick
disconnect coupler. This coupler simplifies
shaft alignment and installation.
a. Use the arrows on the shaft and tube to
align and slide the PTO quick coupler onto
the deck splined shaft.
b. Reaching under the tractor, pull the ring
back on the coupler, slide onto the spline
shaft on the tractor, and release the ring.
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.
