Just wanted to follow up and say I got everything installed on the G100 and it tills like a dream. No front weight was required. Cut out a large area in the side field yesterday and never broke a sweat!
I use my Scotts S2554 for tilling, mowing, and snowthrowing. The only real problem is the axle hubs. I have a few posts on changing the hubs to a cast iron and better key stock setup. I also made a follow up video on the different hubs styles. Scotts 2554 axle/hub swap from a John Deere 345
