Depends how you use it.I love the plastic on the Deere, no dents, no rust, no paint chips, no rattles.
Well, you don't say where you are so I don't now if you have sissy woods or real woods.I have used it extensively in the woods skidding, the trees bounce off the plastic. Hydro static is very nice no gears always the right speed no shifting.
Only problem to start was getting enough ballast in the right places the stock tractor is very light. Once that was fixed its a champ.
There is one thing that helps on the Deere's between 1000 and 4000 series is that "some" dealers include a 10 year drivetrain warranty.I don't know how John Deere remains competitive in the compact tractor realm. They are not what they used to be with their old 50 and 70 and 4003 series tractors. Plastic parts galore. Aluminum gear housings and sub standard capacities as a result. Plus they are not ashamed to charge for this, what I think is a compromised machine.
Fab a skid plate for the Mahindra.
