What I did with my mower deck - My major problem was the rear roller thing often catching while backing up, flipping the deck up vertical. Looking at the geometry, the brackets that hold the bar for the rollers stick way down, close to the ground. Also, sharp turns really drag those rollers sideways across the grass. My yard is nowhere near golf course green smooth. I bought 3" diameter caster wheels from McMaster Carr. I welded up frames similar to what GE made for the front casters, and made brackets to mount them on the rear corner brackets that the bar brackets were bolted to. Each caster uses 2 wheels side by side, to get some of the wide effect that the old rollers would have. I used the same diameter shaft and sleeve and nylon bearings and spacers as they used for the front casters. I also made a 3rd one for the center, to act like the center front roller, so it doesn't scalp a high spot / point. As part of this caster's mounting, I added a stiffener angle iron across the rear of the deck. I also added a 1" square tube from front to back over the side exit chute to make the deck more structurally sound. I get far fewer flip ups while backing now. I do occasionally get a scrape from the middle caster, if I'm on a high spot, but I am ok with the trade off.. I do have pictures of this stuff, don't recall if I can post them via this group. I also have them on my facebook, since I'm on an ET group on there also. Dave
