Although I think they are isolated incidents... yes, one poster had a problem with an engine bolt(s) too. A search in Kubota shows a few bolt issues. I think maybe all of them may at one time or another have an issue or two with something, but as stated... nothing major on a regular basis.
Another poster in the Mahindra forum states that his Mahindra dealer sells M-F and Mahindra and has had no service issues for the five years he has been selling them.
I had a lengthy conversation with Dick Helms at Helms and Son Tractor in Mongtomery, Alabama who sells NH and Mahindra. Nothing but good to say about Mahindra... no service or warranty issues. I also spoke with Louis Pound of Pound Tractor in Florala, Alabama who sells Farmtrac and Mahindra and has had no service issues. There were several others I spoke with as well that had no service or warranty issues as long as they had been selling them (I just had longer conversations with Mr. Helms and Mr. Pound). There was one dealer that told me that they had to replace a clutch and they stated it was a customer fault, although Mahindra supposedly paid for it.
If you want to find out what dealers in your area are saying about Mahindra and what other brands they might sell in addition to Mahindra, go to
www.mahindrausa.com and do a dealer search and call each one of them. That's what I did... I called everyone I could locate within 150 miles... I input zip codes further away from me to reach out and grab a few extra dealer names.
I would recommend calling all the various dealers of each brand you are interested in, or better yet, visit as many as possible and talk with them, check out their service department... get a feel for how good the dealer will be in service and warranty situations. I went to the local Kubota dealer here in Pike County, Alabama, Linton Tractor Company, and they had no sales person available to speak with me. There was one parts guy there who I waited several minutes to speak with before he finally told me that the sales lady had taken a vacation and wouldn't be back for a week and a day. He could give me prices but he said I'd have to go look at them by myself because he was hopping around on a broke foot. I called the owner on his cell phone, Dane Linton, as I know him pretty well and I'm good friends with his brother Lane, who is a silent partner in the tractor business, but Dane couldn't even give me prices... said I'd have to wait for Lisa to come back off vacation. Go figure. I also visited the John Deere dealer here in Pike County... Henry Farm Center. I waited at least 10 minutes before one of the salesmen got off a personal phone call to speak with me. There were several (3 to be exact) guys standing around in the parts area and none of them offered any help... they were just talking to each other, laughing and carrying on. I finally deliberately walked over to one and ask him if there were any salesmen available to look at a tractor. He tried to get one of the salesman's attention but couldn't... said maybe he'll be with me in a minute. One salesman came out and after talking with me for few minutes decided I needed to speak with the other guy who was still on the phone. Nice guy after I finally got to speak with him but his prices ended up being way higher than other JD dealers within an hours drive of me. You will find that not every dealership is the same... some want to sell tractors and some don't act like they care too much whether they ever sell a tractor again or not. It likely wouldn't matter what brand they sold, either way, I wasn't comfortable when I walked out of either one of those dealerships. When I went down the road to the M-F dealer, he was right there on me... walked me out to the yard, very prompt and courteous and bragged heavily on his service department. These are just some things you might take into consideration... the Mahindra dealer in your area may not be someone you will feel comfortable dealing with and that may help you make up your mind or cause you to venture out to a dealer a little further away.
