Wheel Spacing

Set the tractor wheel spacing to at least twice the row
spacing distance. For example: If the row spacing is 76
cm (30 in), adjust the wheels to 152 cm (60 in). Set all
wheels equally from the tractor centerline.
When operating on hillsides or steep slopes, set the
wheels as wide as possible for maximum stability and
steering control. If the front axle is adjustable, set the
wheels at the same width as the rear wheels.
Do not position the tractor wheels directly ahead of the
planter row units that will cause soil compaction and
inaccurate seed placement.

Electrical Requirements

The tractor electrical system must provide 12 volt DC to
operate the seed monitor, highway lighting system and
optional hydraulic seed drive controller.
Find a suitable location to mount the seed monitor
console. Connect the leads to the tractor battery and
route the wire harness to the rear of the tractor.
The transport lighting system is connected to the tractor
with a standard 7-pin connector.
