I have used Valvoline 70W90 synthetic in the front axle since the 50 hour service. Use Rotella T 15W40 in the engine and use Rotella HD tractor and transmission fluid in the tranny hydraulic system. The Rotella transmission fluid is repacked Donax TD or Spirax S4 TXM which is the Kioti recommended fluid.This is a tough call…. My dealer said i should stick with 90 weight gear oil instead of transmission oil. Said it will prevent seal leak better.
I never know whos more correct.
Gee, this is the exact same thing im using. I currently hace 1650 hours on mine. Just did the service last week. Washed and waxed the tractor also.
