No problem, I just think that a lot of people have been swayed against buying them on bad input, where they are really great tires for the money. Plus, I think they have a very nice looking tread pattern!
On the Massey, I did get him to use the 10. We tried a bit to get the 10 running, but with the good coil pack, we could not get it to fire. We tired either carb and still no fire. (IMHO, I think (and hope) that it may be the stator coil that is not charging the coil. I may send them both out as the motor would be a great swap for my son's MF-8
We put his 12hp motor onto the MF-10. Then we swapped his wheel weights, his steering wheel and the seat. We also installed the headlight kit from his 12 onto the 10. I am now working on getting his rough mower deck onto the 10. There are some other parts that were swapped over too, pretty much all the best parts onto one tractor. I plan to use the wheels from his old Massey on my John Deere, and the I may be able to use the factory electric lift switch from my Massey when I add the 12v actuator. Plus, I took the stock seat pan from the 10 and plan to send it out to have the pads redone.
