Walker MT Assembly Instructions, Installing PTO Quick Coupler, Coupler Ring “Locked” Position

Assembly Instructions

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 help- ful 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 rectangular 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 seat- ed in the groove and the ring in the full forward po- sition (refer to the Coupler Ring “Locked” Position photo). After installation, pull on the shaft to check for security.

7.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. Refer to Deck Counterweight Spring Installa- tion photo.
