Warranty work lessons learned.

it's nice to not have to use $$$ OEM fluids.

I like the coolant recommendation too: "Antifreeze".

Most manufacturers these days will have a dual spec for coolant antifreeze. Changes every 6-10 years on their specially-formulated OEM coolant, or every 2 years with generic.

The RK 37 shows the same spec. I have been thinking about buying one and that spec confused me. I think I'm going to talk to Rural King about it.

I was also confused by that bogus spec, so talked to the shop manager at RK. The guy they had then was ignorant as a bucket of rocks. Caught the lead mechanic and asked him. He said the manual was wrong and do NOT put AW32 hyd fluid or gear oil in it! And that they used the RK Providence store brand of "Premium Trans-Hydraulic Oil, Multi-Trac Formula for Use In Most Applications" that meets the John Deere J20C spec.

Also, to the OP, if you're still having warranty/repair issues, RK does have a traveling "troubleshooter" guy for their tractors that takes care of problems like yours. If your local dealer won't help you or help you get in touch with him, they have a corporate customer service line. I know that the guy came to our dealer in Muscle Shoals, AL, to work with the mechanics to fix some kind of a problem on a RK55 a couple of years ago.
