I know that NH has a 2 year warranty on there tractor, 1 year on the FEL and attachments. When I looked at the Workmaster 37, I liked that tractor but it was way over priced, the warranty was terrible and the dealer took 2 weeks to get me a quoit! lol I made my mind up on a Mahindra 1533 HST by the time he got back with me.
JD and Kubota had 6 year warranties I believe and Mahindra has 7 years, Mahindra also offered the best financing of the 3, for me I wanted a longer term with less down and Mahindra did the best there.
I would buy a 1500 series Mahindra and wouldn't look back, not sure about the rest because I didn't research other lines Mahindra has.
I ended up buying a 4 family JD instead, the Mahindra 1500 line competes more with the 3 family JDs but it's funny that the 1533 will lift 1650lbs at full height, my 4320 will lift 1740lbs.
The 1533 weights around 3160lbs my 4320 non cabbed weights 3850lbs.
I just compared a 33hp to a 48hp tractor and Mahindra can hold its own.
Mahindra CUTs stack up very high against the competition as far as there capabilities.
It doesn't matter what color the tractor is, they all break down, some a little more than others.
You can start this thread in any brands category and get horror stories, I have heard just as many about JD and Kubota, seems quite a few guys on here had the same experience I had with NH.
