Tractor/Sprayer Hookup
!
WARNING!
Be certain that tractor lift capacity is adequate and that tractor 
is weighted to maintain steering control. Failure to do so may 
cause loss of vehicle control. Refer to Tractor Specifications, 
“Specifications and Capacities,” page 25. Consult the tractor’s 
operator’s manual for tractor weighting recommendations.
1.
Determine the pin and spacer orientation needed for 
the tractor, and securely fasten the hitch pins.
2.
Mount the 3-Point Sprayer to a tractor with the correct 
pin mountings determined from instruction Step #1. 
Make sure that the sprayer frame is level so that after 
the boom is assembled, it won’t hit the tractor cab 
when the boom is folded or raised.
IMPORTANT: The category 4 narrow hitch (CAT IV-N) 
spacers are not standard parts supplied with the 3-
Point Sprayer. Order 501-011S from an Application 
Systems dealer for the Cat IV-N spacers.
NOTE: Be sure that the top 3-Point link is adjusted cor-
rectly so that the frame is level in operating position but 
will not hit the cab in transport. The tractor 3-Point arms 
should be adjusted to keep the sprayer level from side to 
side with lift arm rigid.
