Yes quality control was lacking over in India. I like my tractors. I bought 2 Montana 675 DTC tractors for the price of one John Deer with the same HP. I now have 225 HR on one and about 150 on one. I use them for logging, running a wood splitter, farming etc.
Just planted 25 ac of corn. Planting beans next weeks. They have been good tractors but I had to tighten a lot of bolts, install missing grease fittings and such when I got the tractors a few years ago. First thing I did when I unloaded them was change all the fluids. AT 100 HRS I changed them again along with the filters. I hope they will last me a long time. On a side note I had an older Ford 3000 and Ford 5000 that I sold after I bought the 675's I owned them for about 20 years and never had any problems other than leaking seals and a little oil use.
