The 6230 is a lower spec tractor that has less frills. The 6230 Premium comes standard with 29 gpm. The non-Premium 6230 is standard with 21.1 gpm and has optional 29 gpm. There are other differences also between Premium and non-Premium. Power brakes vs. non power brakes, 4 valve per cylinder engine vs. 2 valve per cylinder, and alot of electronic differences. The non-premium 6230 should handle your haying operations ok. The brakes and hydraulics are the most critical differences. I suggest you test drive both versions to see what you like. hook up something to the hydraulics to see cycle time differences. What kind of hay equipment are you running?
