I have read through articles this site for a long time and now I need the wealth of knowledge found here to determine the year of this tractor I bought yesterday. Any help is greatly appreciated. The tractor has power steering and one set of rear remotes. It cranks immediately and everything seems to work properly except it doesn't go into 4th gear. I plan to use it with a rotary cutter and box blade so going fast is not required. I know the man I got it from and he used it the same way for many years, it didn't shift to 4th when he got it but he never looked into why. many thanks in advance for help and advice. Does the M&M casting mean Mahindra & Mitsubishi?
