What oil did Deere use in the hyd system on the hundred series combines? I have a Deere 105 and the hyd system uses engine oil. I am adding a hyd pump, reservoir and flow control valve off a hundred series machine (separate from the 105 hyd system)so I can run a hyd. drive reel on a 213 flex head or even the reel on a 100 series ridgid head. Thanks Tom

For whatever reason, Deere recommended engine oil in the newer 9500s too, and skid loaders, too. I've always used a hy-gard equivalent. I was told at least with skid steers, Deere assumes many operators only have access to one sort of oil. I know that sounds like BS, but it's what I was told.

I guess we should note that combines and skid steers use open center systems???
 
A lot of hydraulic systems call for engine oil . The manual also states John Deere all weather hydrostatic fluid which Is lo vis hygard today or type automatic transmission fluid
