To perform leveling, the drill must be hitched to a tractor,
with at least the hydraulics connected.

Raising openers on unfolded, unhitched drill will cause drill
tongue to rise suddenly, which could cause serious injury or
death. Be certain that drill is hitched securely to your tractor
drawbar and the safety chain is securely attached to tractor
before raising openers and unfolding drill.
