Hook-up Transport Safety Chain
DANGER
!
To avoid serious injury or death:
•
Always hook transport safety chain (#1) to deck hook (#2)
when deck is rotated up for inspection, when transporting,
and when parking tractor and cutter with deck rotated up.
Never go near the deck underside or deck pivot points until
after it is secured with the transport safety chain, and never
rely on hydraulics to secure the deck rotated up.
•
Tractor control lever for the deck pivot cylinder must not be
in float detent position while hooking-up transport safety
chain, while chain is hooked to the deck hook, and when
unhooking the transport safety chain. Otherwise, the deck
could fall suddenly causing serious injury or death.
1.
If engaged, disengage power take-off, park on a level
surface, and place tractor in park or set park brake.
2.
Fully retract extension arm cylinder.
3.
Fully retract deck pivot cylinder (#4) to rotate deck
completely up.
IMPORTANT:
Set tractor control lever for deck pivot
cylinder (#4) in self-cancel detent before hooking up
transport safety chain.
4.
Lower 3-point arms until deck pivot joint is resting on
the ground.
5.
Turn off engine and remove switch key to prevent
unauthorized starting.
6.
Hook transport chain (#1) to deck hook (#2).
Unhook Transport Safety Chain
1.
Park on a level surface and place tractor in park or
set park brake
2.
Fully retract deck pivot cylinder (#4) to rotate deck
completely up.
3.
Lower 3-point arms until deck pivot joint is resting on
the ground.
4.
Turn off engine and remove switch key to prevent
unauthorized starting.
5.
Unhook transport safety chain (#1) from deck
hook (#2). Do not force safety chain (#1) off of deck
hook (#2). If safety chain does not remove easily,
investigate cause and correct the problem before
continuing. Make sure tractor control lever is set to
self-cancel detent.
6.
Once unhooked, store transport safety chain (#1) in
storage hook (#3) by hooking the chain 15" from its
free end. The chain should hang from the hook in
3 segments that are approximately equal in length.
7.
Return to the tractor and extend deck pivot cylinder to
rotate deck down.
8.
If deck is equipped with a gauge wheel, place tractor
control lever in float detent position before traveling
with deck supported by the gauge wheel.
IMPORTANT:
Transport safety chain should
remained hooked to the deck until ready to lower the
deck down.
IMPORTANT:
Tractor control lever for deck pivot
cylinder (#4) must remain in self-cancel detent when
unhooking transport safety chain.
