About to do this getting ready for mowing season. Guess it doesn't matter changing the pump oil while cold or warm?
1. Remove filters, drain oil
2. Install new filters
3. Add oil in the fill tanks until it reaches the cold level mark
4. Raise the rear of mower until rear tires off the ground. While at idle slowly move the control arms back and forth about 6 times. Check the level of oil in fill tanks see if it drop.
5. Come back after everything has cooled down and check oil level...
