MAINTENANCE

WARNING: Never clean, lubricate or adjust a machine that is in motion. Failure to heed may

result in serious personal injury or death.

COULTER BLADE WEAR

Blade wear can affect performance in loose trash conditions. Depth control and plugging problems can result. It

may be necessary to replace blades.

WARNING: If required to service unit in raised position, be sure to close the hydraulic valves.

Place a safety stand under the toolbar. Failure to heed may result in serious personal injury or

death.

DANGER: Inspect and replace worn or frayed hydraulic hose. Keep all connections tight.

Escaping hydraulic fluid under pressure can have sufficient force to penetrate the skin and cause

serious personal injury. Fluid escaping from a small hole can be almost invisible. Use a piece of

cardboard or wood rather than the hands to search for suspected leaks. Failure to heed may result in

serious personal injury or death.

LUBRICATION

WARNING: Never clean, lubricate or adjust a machine that is in motion. Failure to heed may

result in serious personal injury or death.

Lubricate with general-purpose grease

•

To ensure longevity and reliability of the All Steer Plus ™ Fertilizer Toolbar, each coulter assembly

has (2) grease fittings. Grease the pivots weekly. Grease the hub four times per season. Repack the

hubs once per season.

• There is a grease fitting on each end of the upper and lower parallel arms. Grease every 10 hours.

BEARING ADJUSTMENT:

1. Raise the toolbar until the blade is clear of the ground. Place a safety stand under the toolbar. Remove

the hubcap, cotter pin, slotted nut and washer from the hub assembly. Remove the blade from the hub

assembly.

2. Remove bearing cones and seals from hub.

3. Wash the old grease from the hub, bearing cups, spindle spacers, seals and bearing cones. Inspect the

condition of the bearing cups, cones and seals. Replace if necessary.

4. Apply #2 multi-purpose lithium grease on each bearing. Make sure the space around each roller is filled.

Lubricate the bearing cups.

5. Position the bearing in the cup and install the seal. Lubricate the seal lips and proceed with re-assembly

of the removed parts including the blade. Blade bolt torque is 90 to 96 ft. lbs.

Tighten the slotted nut to 15 ft. lbs. or until a definite drag is felt when the hub is turned by hand. Tighten the nut

one-slot position to line up the cotter pin hole with a slot. Secure the nut with a new cotter pin, replace hubcap.
