Checking High Speed Fertilizer Openers

CAUTION: To help prevent severe injury or death to you or someone else:

Make sure air has been properly bled from opener hydraulic system.

Keep all persons away from machine when raising and lowering openers.

Always locate machine on level ground when raising and lowering openers.

1. Place tractor transmission in PARK and/or set brakes, then start engine and pull back on SCV II lever (A) to retract fertilizer opener cylinders.

2. Move SCV II tractor control lever back and forth several times while observing operation of openers. Openers should raise when lever is pulled back and lower when lever is pushed forward. If action is reversed, reverse hose connections in SCV II hydraulic coupler.

If openers do not operate smoothly, air may be trapped in cylinders or hoses. (See INSTALLING AND BLEEDING FERTILIZER OPENER CYLINDERS in Service section.) If after bleeding, machine still does not operate properly, see John Deere dealer.

3. After attaching and cycling cylinders, check tractor hydraulic oil reservoir. Add oil if necessary.
