Service Mower

c CAUTION: Avoid injury! Before you dismount to unplug or adjust mower:

· STOP the engine.

· LOCK the park brake.

· DISENGAGE PTO to stop mower blades.

· Remove key.

· Wait for reel blades to STOP.

· Keep hands, feet and clothing away from cutting units when engine is running.

· DISENGAGE PTO to stop reel blades when you are not using mower.

KEEP SERVICE AREA CLEAN

c CAUTION: Avoid injury! To help prevent personal injury, keep the service area clean and dry. Wet or oily floors are slippery. Wet spots can be dangerous when working with electrical equipment.

Be sure all electrical outlets and tools are properly grounded.

Use adequate light for the job at hand.

Never lubricate or service machine while it is moving. Keep hands, feet and clothing from power-driven parts. Disengage all power and operate controls to relieve pressure.

Securely support any machine elements that must be raised for service work.

MIF

Understand service procedure before doing work.

Keep all parts in good condition and properly installed. Fix damage immediately. Replace worn or broken parts. Remove any buildup of grease, oil, or debris.

Grease

Use grease based on the expected air temperature range during the service interval.

TS1411

NOTE: Lubricate IMMEDIATELY after washing the machine to remove water before bearings cool and "suck in" water and contaminates.

The following greases are preferred:

· John Deere MOLY HIGH TEMPERATURE EP GREASE

· John Deere HIGH TEMPERATURE EP GREASE

· John Deere GREASE-GARDTM

Other greases may be used if they meet one of the following:

· SAE Multipurpose EP Grease with a maximum of 5% molybdenum disulfide.

· SAE Multipurpose EP Grease

Greases meeting Military Specification MIL-G-10924F may be used as arctic grease.

PERFORM LUBRICATION AND MAINTENANCE

c CAUTION: Avoid injury! Do not clean, lubricate, or adjust machine while it is running.


IMPORTANT: Avoid damage! The recommended intervals are based on normal conditions. Severe or unusual conditions may require shorter intervals.

NOTE: Do not overfill as oil may expand during operation and spill on turf.

Clean grease fittings before lubricating. Replace lost or broken fittings immediately.

MOWER HYDRAULIC OIL

Use John Deere J20C specifications or an equivalent. DO NOT use type "F" automatic transmission fluid or J20D Low viscosity HY-GARD. John Deere HY-GARD (J20C) transmission oil is specially formulated to provide maximum protection against mechanical wear, corrosion, and foaming.

CUTTING UNIT GEAR CASE GREASE

John Deere Cotton Picker Spindle Grease is recommended for cutting unit gear case.

If other grease is used, us e SAE Multipurpose Grease meeting NLGI Consistency Number 00.

CUTTING UNIT GEAR CASE

Pack gear case to fill plug (A) with John Deere Cotton Picker Spindle Grease or other SAE Multipurpose Grease meeting NLGI Consistency Number 00. See Cutting Unit Gear Case Grease in this section.

BEFORE EACH USE

1. Check hydraulic oil level in tank. Add oil as necessary.

2. Check hardware.

3. Inspect hoses for wear. Replace damaged hoses.

4. Check for oil leaks. Tighten fittings and replace seals as necessary.

5. Check for bent or broken reels and replace.


IMPORTANT: Avoid damage! Damaged reels will provide an uneven cut and could cause damage to the machine's hydraulic system.

6. Check cutting reel and bed knives for sharpness and nicks.

7. Check reel-to-bed knife settings and adjust as necessary.
