WEll, first like you two said, hydrolic couplings. Took 3 weeks to stack 6 bales. We'd pick one up and oil would spray all over the front of the windshield and entire front of tractor. We'd blow fuses on fuel pump, the ignition, you name it, if it had a fuse it'd blow it. We were letting the tractor warm up and turned on the windshield wiper. It blew a fuse, and for some stupid reason, the same fuse is for the ignition, so the tractor quit. Every time you either turn on a blinker, hazards, or turn the fan speed up, the temperature guage goes up. When its 100 degree's outside, its 120 inside, cause if you turn up the fan the tractor will shut down thinking its too hot when its really not. Some guys took thermostats out, that helped some I guess, but then I believe the tractor doesn't get up to operating temperature. When it really would overheat, such as cutting with a crimmper, the radiator would plug every round. You'd have to get out, turn it off, pop the hood, and clean off the radiator every round or so if the wind was just right. Um, we've had about 10 windows shatter out of it, not hitting bumps or nothing just out of the blue. The list goes on and on. THe radio sounds like its out of a Model T or something, it just sucks. The heat from the engine melted our batteries in time, but the company replaced those. The new update moves the batteries to the side. Its just been one headache. When it works right, its a great tractor. You have to pull back on the hydrostat to pull hills cause its underpowered though, not even with a load! You say you like yours howeverIJ By the time we had 400 hours ours had been in the shop, oh, I'd say a dozen times at least and thats no exageration.
