NTA607HD Lift Assist Adjustments
General Information
This manual is an instruction guide for reducing load on
the caster wheels or for operating with the caster wheels
fully off the ground. The result will make the NTA607HD
unit more suitable for conventional soil conditions rather
than no-till conditions.
Removing weight bar sets and adjusting the pressure
reducing valve will result in less load on the caster
wheels and less severe tracks in the field, especially in
muddy conditions.
Tools Required
• basic hand tools
• a forklift or similar hoist capable of lifting a minimum of
374kg (825 lbs)
Work Location
Move the implement to a flat location
