I knew NH owned Iveco, I thought I admitted in my follow up that I did not know Fiat created Iveco to market their motors. Iveco has a great reputation around here and in Europe. I had thought that Fiat had acquired Iveco much like Agco just aquired Valtra for the Sisu motor.
I can tell from your post that you do not have anything against the TN except the motor. Why do you dislike the motor in the TN when you have not heard of any problems with the TN motors. I have friends who have the same motor in the TNF and put over 1000 hours on it a year with no problems. The TN motor and tranny is bullet proof and the reports on here as well as the garages should be proof enough. You never hear anyone say they are having a problem with the motor on their TN. It is usually a loose fitting or a wire got knocked off by a stick and it is the electrical that causes most problems on these newer tractors.
Comparing the TN to the 30 series is understandable. I had the choice to buy a 3930 or a TN65. The TN was so much better then the 30 series as far as operator comfort, layout and service. The TN is easy to work on and the loader comes off quick and easy. The 3930 is a great tractor but was dated and was long overdue to be replaced. I grew up on tractors and all my experience is on Fords and Masseys. The only JD's I have now are two JD-M's and an H. I have run Fords since I was 12 and a couple Masseys since I first learned how to run a tractor (don't remember how old I was then).
If I did not buy my TN I would most likely have bought a JD. When I was looking in early 2000 for a tractor to replace the Ford 4000 I talked to all the dealers. My MF/Kubota dealer wanted to sell me a 231s and could care less that it did not meet my needs. Agco Allis was a joke and was $5k more then NH. Case-IH was the same price as the AA. JD was $1400 more then the NH and 20 miles further away. I love my TN but I am not loyal to any one brand. I live two miles from my NH dealer. I have a great relationship with them now and will continue to deal with them. But I am seriously considering buying a Valtra if they give me a good price. So far the TS-A is about $3k less then the comparable Valtra.
My main work for the TN is haying, it is underpowered and undersized for my baler but I had the TN before the baler. The TN was bought to do our field work and we use every hp that it has. We pull a 3-16 plow and a 12' Int. transport behind it. We plant with an IH 56 4row corn planter. Weight is a big issue with us, compaction is not as a bigger tractor will weigh more and unless we get flotation tires it will not change the psi much put down by the tires. I need all the weight I can get to handle the disc, if the conditions are too bad I use our 10 footer. I will not baby this tractor which is why I took offense to your post about the motor being junk. Hope this clears things up some. Take care and enjoy the evening.
