We have the wire that cleans of the rear roller .The issue is the verticutters throw the clippings forward for the front roller to pick up . It will increase the front roller dimension by a good 1/2 ".After looking in the parts book I didn't see clearly if there are front scrapers available . Being in a new shop there is some left over building materials. I happened to save a bunch of 5/16th threaded rod .
Perfect and the price was right . The front rollers are set for the + -HOC that we use and most likely will never change . As you can see in above picture there is a space just big enough to get the threaded rod in the front roller arms .
Fairly simple to do only took 45 min.to do a 5 set installed .
Thread the nuts on a fair way ,more so on one end to slide in place with a backer washers . Then washer lock washer and nut on the outer end . Tighten the inside nuts till their just touching the washer and roller arm . As the outside ones are tighten it will draw the threaded rod tight .
Cut excess off . Turned out great and pretty easy to do . Now the clippings will get trapped on rod and wipe roller . Excess clippings will drop off the back .
