How to add hydraulic oil to Kohler pro 20 - Craftsman 20 Hp 42" Deck Lawn Tractor

Either badly seated oil rings or PVC valve is stuck open allowing oil to enter through carburetor.

10w30... And I use ONLY Kohler 10w30 in my customers Kohler engines.

Now the hydraulic system in the Woods mower most likely uses a 20w50 MOTOR OIL but it's been about 5 years since I have even seen a Woods unit. www.woodsequipment.com

The motor takes 30 SAE. the drives take 20/50 SAE motor oil. I contacted the manufacturer of the hydro gear drives to find out what was used when I rebuilt one. There is only one manufacturer of all hydro gear drives. Their recommend Mobile 20/50 SAE.

Yes I agree. I would figure that out first before changing the engine.

Hello, If you have a Kohler Courage engine, you need to use 10w30. It has hydraulic lifters and requires the use of only this grade of oil.

Hope this helps.

The standard mix for most chain saws is 40:1 that's about 3-1/4 oz per gallon.

The parts store,napa sells a air compressor oil that is compatible,It is called simply,air compressor oil.It is made just for compressors.

Hydraulic fluid straight from the drum, has a typical cleanliness level of ISO 4406 21/18. A 25 GPM pump operating continuously in hydraulic oil at this cleanliness level will circulate 3,500 pounds of dirt to the hydraulic system's components each year! To add hydraulic oil, and not the dirt, always filter new oil prior to use in a hydraulic system. This can be accomplished by pumping the oil into the hydraulic reservoir through the system's return filter. The easiest way to do this is to install a tee in the return line and attach a quick-connector to the branch of this tee. Attach the other half of the quick-connector to the discharge hose of a drum pump. When hydraulic oil needs to be added to the reservoir, the drum pump is coupled to the return line and the oil is pumped into the reservoir through the return filter. As well as filtering the oil, spills are avoided and the ingress of external contamination is prevented. The benefits of carrying out this simple modification are well worth the minor cost involved.
