Tractor Drawbar
Length
FIG. 12: Adjust the tractor drawbar length so the pinhole
is 356 mm (14 in) from the end of the PTO shaft.
NOTE: The dimension must be 36 cm (14 in) for both
540 and 1000 rpm pumps.
IMPORTANT: Fasten the drawbar on the tractor
centerline.
Three-Point Hitch
4 and 6 Row: Cat. II
8 and 12 Row: Cat. II or III
Three-Point Hitch Adjustment
Before connecting the planter to the tractor:
•
Adjust hitch sway blocks and stabilizing bars to
provide minimum lateral hitch sway. The planter must
not swing into tractor when planter is in the raised
position.
•
Adjust length of lower lift links so center of hitch
latches are 15 cm (6 in) from the ground in the
fully-lowered position.
•
Adjust the lower links to the float position to ensure
planter drive wheels are continuously contacting the
ground during operation.
•
Adjust hitch draft control for average conditions.
See your tractor Operator Manual for more specific hitch
adjustment information.
Quick Hitch
Adjust the standard three-point hitch, then connect the
quick hitch.
NOTE: If the planter is equipped with lift assist wheels,
remove the quick hitch upper hook.
