I have been using a Mahindra 1815 for a couple of months now. It had 260 hours on it when I bought it. It is a great little tractor and because they have such poor resale value I got it for a great price. Like all guys I would like more power but it does a great job for what it is rated for.
It is great on fuel and runs like at top. My only issue is because I am very tall it is a little tight for me, my knee is right up against the hydraulic controls and I haven't figured out how to move the seat to make more room for myself. As well, the hydrostatic foot control is a little small for my big feet.
However, in fairness, this would not be an issue for very many people. I am looking for attachments to use with it.
