During operation:
• Each time openers are lowered, hold tractor remote
hydraulic lever forward for a few seconds to recharge
circuit, then return it to its neutral position. The tractor
and drill should be on level ground when returning
tractor lever to neutral.
• When approaching rough terrain where you need
active hydraulics to maintain even opener penetration,
push tractor hydraulic lever forward momentarily. As
soon as you return to level ground, return lever to neu-
tral. Do not activate tractor hydraulic lever for more
than 20 seconds at a time, once every 2 minutes.
Always wait until tractor and drill are on level ground
before returning lever to neutral. You can bump tractor
hydraulic lever forward any time on level ground to
assure the preset pressure is correctly locked in and to
reset the system.
• Always raise openers before turning. Never back up or
turn sharply with openers in the ground. Doing so will
plug openers and may damage equipment.
