Changing Wheel Drive Lubricant
The wheel drive lubricant should be changed after the first 50 hours and then in accordance with the maintenance
schedule. Change the lubricant when it is warm.
Check the level every 200 hours or annually, and change
every 1000 hours.
DANGER
Stop engine and remove key from ignition before
leaving operator's seat for any reason. A child or
even a pet could engage an idling machine.
1. Park windrower on level ground and position
windrower so drain plug (B) is at the lowest point.
2. Shut down the windrower and remove key from
ignition.
3. Place a large enough container (about 2 quarts
[2 liters]) under the lower drain plug (B).
4. Remove top plug (A), and drain lubricant. Ideally, the
lubricant should be at operating temperature for good
draining.
CAUTION
Dispose oil in a manner that is in compliance with the
local rules and regulations.
5. When lubricant has drained, rotate wheel so that one
of the plugs (B) is horizontally aligned with the center
of the hub (C) as shown.
