SERVICE INSTRUCTIONS
Mower Deck Installation on Tractor
Deck Installation - Model MC, MD, MT, MTL, MTEFI
1. Lightly grease each deck support arm (2) on the
tractor. Refer to Mower Deck Installation photo
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 sock-
et location). Slide the deck onto the support
arms: all the way if SD equipped model, approxi-
mately 3 in. (76 mm) if GHS equipped model.
NOTE: When installing the DSD52 (or DSD62 -
MT, MTL, MTEFI, MD) 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 mod-
el), 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 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 Installation photo).
Two (2) hitch pins are included in the owner's pack-
et of materials.
5. Connect the mower deck PTO drive shaft assem-
bly 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” Po-
sition photo). After installation, pull on the shaft to
check for security.
