The oil in a hydrostatic transmission is responsible for lubricating the gears and other moving parts, and it also helps to cool the transmission. Over time, the oil can break down and become contaminated with metal shavings and other debris, which can lead to transmission damage.
To change the oil in a John Deere LX188 hydrostatic transmission, follow these steps:
1. Park the tractor on a level surface and engage the parking brake.
2. Allow the tractor to cool down completely.
3. Locate the drain plug on the transmission housing.
4. Place a drain pan under the drain plug and remove the plug.
5. Allow the old oil to drain completely from the transmission.
6. Replace the drain plug.
7. Locate the fill plug on the transmission housing.
8. Remove the fill plug and add new oil to the transmission. The type and amount of oil required will vary depending on the model of tractor.
9. Check the oil level and add more oil as needed.
10. Replace the fill plug.
It is recommended that the oil in a hydrostatic transmission be changed every 100 hours of operation or annually, whichever comes first.
Note: If the oil in your hydrostatic transmission is discolored, milky, or smells burnt, it should be changed immediately.
