First picture: bent bar on right goes thru body where deck raise was and connects with rod inside then out to a set up that when you pull back it rotates bar then lift blade which is mounted to frame ahead of rear tires. Bar next to bent bar and beside hood is mounted to frame with threaded rod thru body to blade with eyelets which when pulled to back it rotates blade to left then when pushed back forwards it rotates to right. If you blow up 3rd pic. you should be able to see where it pushes back then pivots blade to go up.Rod on left fender is for forward and reverse There is a cable under seat that I pull to lift eye bolt up to let blade swing either way. Works much better in reverse than forward as it can turn sharper onto sidewalk instead of back and forth to line up when going forward similar to driving tow motor.
