Well I wasn't happy with the motor mounts so I reworked them today and I am much happier with the tractor know. Here are some picks of the the motor setups leading to what I ended up with today.
First motor setup that didn't last long at all.
The next setup worked but it wasn't tight in the housings and allowed the motors to rock back and forth.
And finally what I did today.
Now when I split the tractor the only thing connecting the two halves are the motor wires.
Thanks for looking.
