1. Park the tractor on level ground and turn off the engine. Allow the tractor to cool down for a few minutes.
2. Locate the hydraulic fluid reservoir. It is a black plastic tank located on the left side of the tractor, behind the seat.
3. Remove the reservoir cap.
4. Check the fluid level. The fluid should be between the "FULL" and "ADD" marks on the dipstick.
5. If the fluid level is low, add hydraulic fluid until it reaches the "FULL" mark.
6. Replace the reservoir cap.
Note: The hydraulic fluid should be changed every 1,000 hours of operation or annually, whichever comes first.
