504G3 SERIES TRACTOR OPERATION MANUAL

• Adjust sway chains
IMPORTANT: Do not shorten sway chains so short that do not allow hitch to be raised
completely. If sway chains prevent hitch from rising, hydraulic relief valve opens, cause
excessive oil heating and pump or equipment damage.
NOTE: Use spring or rubber strap to keep draft links clear of rear wheels when draft
links are not attached to implements.
Check implement operator’s manual for instructions whether to allow side sway. You
can adjust the length of sway chains by loosening the jam nut (fig4-25) on sway chain
strainer and turning the sway chain strainer to increase or decrease the length of chain.
Tighten the jam nut again when adjusted.
(1) When plough is attached to hitch system, side sway is needed and clearance of side
sway is about 5cm.
(2) When rotator is attached to hitch system, side sway should be clear by adjusting the
length of sway chains.
• Leveling the Hitch
(1) Lower implement to take weight off hitch.
(2) Adjust upper link to level implement front to rear. Rotate the upper link body
clockwise to lengthen upper link or counterclockwise to shorten it.
(3) Ajust lift links to level implement side to side.
When plough with depth gauge wheels is attached to hitch system.
