It's a 3 year old JX75T actually. Just did my 1400 hours oil change. It does a lot of short trips actually.
Bought it second hand last year. So far no real issues except for a starter solenoid that literally cracked open(Bosch part).
Yes... Surprised as well. The manual infact has a paper...
I was able to buy an old Case IH Tractor that has an oil bath air filter. The manual doesn't say much and the dealer has no idea either.
Suggestions as to what level to follow would be most appreciated! I drew a yellow and a red line for convenience....Happy driving and thanks again!
