With the 60" mower you should be good. It's the 54" that has clearance problems.
I beveled the edge of my UHMW edge at about 30°, using my tablesaw. I left about 3/16", so it's not a 'knife' edge, and it'd have a bit more wear resistance. Seems to have worked...so far.
I upgraded my backup camera in my MX series tractor - I decided to get a bigger display and go with a wireless setup vs wired so far I really like it. Also gathering the stuff I need to convert my quick attach coupler to make it hydraulic operated.
