I am really needing an OCDC for my walk behinds this year,blowing grass out of mulch beds is not fun anymore! I built one once but the steel rod that I had to raise and lower it kept getting in the way. I need it to be mounted close to the mower as possible. The mower is a turf tracer with ECS, Ive got a pretty good design started but still wondering how to make a device to push/pull the piece welded to the blocking plate? Any pics of OCDCs on walk behinds would be helpful (or drawings). It might be better to just buy one though, because next week I will have not any time to do any fabricating. (we are starting on Monday as long as the weather continues to be nice)However most of the ones Ive seen are mainly for ZTRs. My design uses extension springs,weldments, steel rods,and a handle mounted up by the controls, but something that you could just kick down with your foot might be better? I appreciate all the help.
