Operation 9
MAN0253 (Rev. 3/10/2007)
OPERATION
Make sure the driveline spring-activated locking
collar slides freely and is seated firmly in power
unit PTO groove. Make sure the set screws
securely attach driveline to the attachment gearbox
shaft.
Do not operate power unit with attachment
removed. Attachment is required for power unit
stability.
Always wear relatively tight and belted clothing
to avoid getting caught in moving parts. Wear
sturdy, rough-soled work shoes and protective
equipment for eyes, hair, hands, hearing, and head;
and respirator or filter mask where appropriate.
ATTACHING MOWER TO POWER UNIT
NOTICE
■ The power unit must comply with counterweight
requirements before attaching to power unit.
1. Place power unit and mower on a level surface.
2. Rotate parking stand to the down position so deck
is resting on the parking stand wheel.
3. Center the power unit behind mower as close as
possible. Shut off engine.
4. Open dump valves on both hydraulic pumps to
allow power unit to be moved by hand. See Mow’n
Machine power unit manual for location of dump
valves.
NOTE: If you have a PowerTilt™ model, the wiring har-
ness must be connected before raising or lowering the
deck to align the arm with the mounting bracket. See
Connect Wiring Harness - PowerTilt™ Units MXT Deck
SN 1100885 and below, page 24 for instructions.
5. Use the height adjustment handle (or height adjust-
ment switch on PowerTilt models) to raise or lower
rear pivot lift arm and align arm with mounting
brackets.
6. Attach rear pivot lift arm in desired power unit
mounting bracket holes and connect with spring-
loaded pins. See Figure 1 for hole locations.
7. Attach driveline from deck to PTO shaft on power
unit.
8. Attach weight transfer chains to right and left
weight transfer brackets on rear pivot lift arm.
NOTE: Stepping on the weight transfer arms with
your foot will make attaching chains easier.
9. Install flat washers and safety pins in right and left
weight transfer brackets to secure chains into posi-
tion.
10. Close power unit hydraulic pump dump valves.
11. After deck is attached to power unit, raise deck
high enough and rotate parking stand into the stor-
age position.
NOTE: Attach rear pivot lift arm in hole position 1 on
deck mounting brackets when front wheels are in hole
1 on front wheel yoke. This will put the deck in the high
cut range, (2 to 5 inches - manual, 1-1/4 to 5-1/2 inches
- PowerTilt™). Attach weight transfer chains to weight
transfer brackets using four links. Use PowerTilt™ in
hole position 1 shown in Figure 1.
NOTE: Attach rear pivot lift arm in hole position 2 on
deck mounting brackets when front wheels are in hole
2 on front wheel yoke. This will put the deck in the low
cut range, (1 to 4 inches). Attach weight transfer chains
to weight transfer brackets using five links.
