I started stripping down the jazzy and removing brackets , wires and controller that will not be used, it has a circuit breaker set for 30 amps , hmm I wonder if I will leave it in, 15 amps max per battery is not a very high ceiling.

Anyways as always feedback is welcome

Ok so I picked up some hardware. 1/2" steel zinc threaded rod , nuts, wing nuts and lock nuts. Should be able to basically slide the shaft in or out by unscrewing a wing nut when done. I removed the original axle and it appears to fit in fine.

Next I need to pull out the grinder and cut away the center post that is in the way and drill out all the holes the shaft will slide through to 1/2"

Using the brackets originally for anti tip wheels , I fashioned an adjustable mounting mechanism for the rear of the mower to rest on. The mount can adjust up or down about 2 inches in each direction. This will allow for adjustment of the cutting height on the rear.

I had to use a grinder to remove the studs and the center beam that had the foot rest mount.

Thanks merne! It has been a learning experience, there were a lot of first for me in this project. I had never used a chain drive before and that was a challenge. Things are more difficult that they look on paper with all the moving parts. I still have about 4 months left of the year grass will grow heavily so I think I will have plenty of opportunities to use it before the end of the year.
