Cheap but good.
Hey I don't have problem with that!
Tractor Supply sells the Traveler brand HTF, Chevron, you have a bunch of options.
One thing to remember just because it's cheap doesn't mean it's no good, and just because it cost more doesn't mean it's the best. Oil and oil services is one of the most opinionated subjects you will ever come across. Everybody is an expert.
My opinion-- if it meets the specifications for your tractor, use it, you want to use synthetic, by all means use synthetic, but I don't necessarily believe it is so much better.
If you are changing hydro/tranny at 500 hours because of service, I think even the cheap stuff would do you a fine job.
