I'm not here to bash a brand or just find every little thing I can to complain about. I'm just fed up after 3 years of numerous annoying things. I can't remember the temp when it "froze up running" but we were using it to put out hay and it would just stop and die. Now I will say, I'm not very mechanically inclined, which is why I bought a new tractor to begin with...to avoid hassles all the time. I mess around on my farm in my spare time and it's not my full time job. But after it died the first time I went ahead and replaced the fuel filter and then ran it again and it did the same thing after about 30 more minutes, if my memory is correct. I put the heater to blowing on it and it seemed to thaw it out after about half and hour and it restarted and ran fine to finish feeding. I do use an additive and I"ll be honest the name escapes me right now but I'll look at the bottle when I get home. I run the same exact fuel through my NH and my Kubota and they have never missed a beat. I've fought fuel issues with this tractor from day one. Summer, spring, fall and winter. It would always throw codes and then throw the fuel rail pressure code and put it in limp mode and I would have to idle it basically back to the barn. They replaced a few sensors and this last time seem to have it running better although it will still throw the one code, I believe it's 31. It's frustrating as ****. I'm at work here typing from memory so forgive me if I give the wrong info. The AC has never worked worth a darn. It just never seems to cool it enough, I've even thought about having the windows tinted. This thing is NOISY. Being new to tractors I didn't realize it at the time but **** this thing is noisy in the cab. My PTO light will flash and go all the way out sometimes and the dealer said that could be a sensor issue too. I also had a sensor of some sort go bad in the transmission that they fixed. There's too many sensors on these things anymore evidently. I love my NH workmaster, it seems simple and it's never given me a bit of problems. Just a good basic tractor. My Kubota is a CTL and I haven't used it enough but I've had no issues so far out of it. The only thing I seem to constantly fight with on my farm is the Massey Ferguson. Like I said I'm not here to bash a brand, just fed up with this thing. I did finally get it started last night though and it worked good enough to get hay out. But that was after trying multiple times and finally putting the kerosene heater on it again to warm it up. This is after having it plugged in too.
