4tilling dirt - the tractor is neither an E series nor an M series. I believe they called it the premium series at the time which was between the E and the M.
I received the tractor back with the axle repaired and at no cost to me. Thanks to Massey for their support. I posted a short youtube video of the ordeal - not sure if I am allowed to post a link here, but you can find it by searching MF 1736 axle failure on youtube's search.
I have already moved a couple of bales of hay with the rear spear with no problems, but will keep a close watch on that axle moving forward. I did find the gas tank fill-up issue was back. I had to fill up about 3 gallons, drive it a bit and then was able to finish filling it. Hopefully that does not persist.
