My tractor was built in 2001, I bought new in Feb 2002 with 3.2 hrs on the clock. It came with the 17.5L tires on the rear. I've always worked my tractor hard but a stickler on maintenance, many say I abuse it and I admit it. I used to break front axle shafts and countershafts in the outdrives pretty regularly, I keep one of each just in case. I worked my tractor for a living from 2003 until 2008 and used it where another piece of equipment would have been proper but I went ahead and got the job done with my little 4110.
My front diff. went down July of 2006, at 1149 hrs on the clock. The studs that the ring gear are mounted to loosened/broke and came apart. Luckily I was able to stop the tractor right away and I didn't do any damage to the bearings, gears or seals and my repair was fairly cheap. It was labor intensive with all the cleaning - you must clean the whole banjo housing out perfectly as well as the small parts and like Galen says - you need to know how to set a differential up properly. A tractor's slower speeds will give you some slight leeway but not alot, you still need to have it set right with the stresses. I pretty much attributed the diff failure to all those axle snaps - lots of shock when that thick axle snaps.
Then, in May of 2007 with 1299 hrs on the clock I had to do a rear split on the tractor to replace a disintegrated bearing on the rearmost 4wd shaft that gets it's power from the rear pinion shaft. The bearing was like $3.96 at NAPA, but the labor was killer !! Not counting hydraulic filters & fluid. While in there I also replaced the small gear that slides on that 4wd shaft and the shift fork that actually works in a groove on this gear - there is a gear on the main pinion shaft that this gear engages when you operate the 4wd shifter. This shift fork bends fairly easily - it doesn't take hardly any pressure on the shifter to flex the finger of this fork - you must be very gentle in shifting in & out of 4wd by rocking the tractor between forward and reverse. When I operate anything on my hitch I always turn in the seat and my left hip/leg would always be touching the 4wd shifter and sometimes pretty hard. After bending my second fork I finally took the shifter off and heated it and bent it away towards the fender so my leg doesn't touch it and am very gentle with 4wd shifts. I've always run mine in 4wd unless on hard surface, early on I thought this might have been part of my front end problems but more recent things seem to disprove that.
After all this between 2006 - 2007, I finally broke-down and spent the money to replace my rear tires as finally recommended by Mahindra to the 16.9x24 size in July of 2007 with 1337 hrs. I replaced the fronts too and stuck with the original size of 12-16.5 so tire diameters were correct. I haven't broken a single thing in the driveline since I put the tires on and I now have 1809 hrs on the clock. I still work the tractor hard, like a little bulldozer and everything else and I keep it in 4wd except on pavement and I do drive it about 10 miles total a year on the road. Maybe I've just been lucky the last 472 hours. I still have my spare axles .....
