MAINTENANCE INSTRUCTIONS

Before operating the mower, make sure that it is properly lubricated and thoroughly inspected. Only a minimum of time and effort is required to regularly lubricate and maintain it. Following a regular program will provide long life and trouble free operation.

WARNING!

Always disengage the tractor PTO before raising the mower for transport or making adjustments.

LUBRICATION

Do not let excess grease collect on or around parts, par- ticularly when operating in sandy areas. The illustration below and on the next pages, show the location of all the lubrication fittings.

Use an SAE multi-purpose, lithium type grease for all the locations shown on figure 7. Be sure to clean the grease fittings before applying any grease. Daily lubrica- tion of the driveline U-joints is necessary. Failure to main- tain proper lubrication will result in premature wear and damage to the U-joints, gearbox and/or driveline.

Figure 7

Lubrication fitting location

Item	Description	Frequency*
1	Gauge wheel pivots	Every 8 hours or daily
2	Blade spindle	Every 8 hours or daily
N/S	U-joints	Every 8 hours or daily

*Lubrication intervals shown are for mowers operating under normal conditions. Severe or unusual conditions may require more frequent lubrication.

GEARBOX LUBRICATION

The gearbox must be filled with SAE 90 EP oil before operating.

To fill gearbox to the correct operating level:

1.Place the mower on an even and leveled surface.

2.Remove filler and test level plug (see figure 8 for location of plugs).

3.Add oil through the filler plug until it starts running out of the test plug. (Pour oil slowly to make sure that the lower portion of the gearbox housing has been filled)

4.Screw the test and filler plugs back in their correspon- ding places.

It is recommended that the oil level plug be removed after every 8-10 hours of operation and oil added until it runs out of the test plug hole. The filler plug hole and test plug hole are both located on the back of side of the gearbox.

Figure 8

Note:

1.It is recommended that the test plug be removed after every 8-10 hours of operation, and oil added to the proper fill level if required.

2.Do not overfill the gearbox with oil. This will result in pressure build up inside the unit, which can cause the oil seals to leak.

3.If the gearbox suddenly starts making an unusual noise, stop at once, check for oil leaks and refill it as required.

GAUGE WHEEL ASSEMBLIES

The gauge wheels are equipped with bearings which require grease regularly. Grease fittings are provided in the gauge wheel pivot. It is recommended that these be lubricated after every 8 hours of operation. See figure 9.
