After using the newer style verticutters for the first time we noticed the front whillie rollers loading up with the debris thrown forward from the verticutting process . We ordered these kits to wipe the front rollers off , the rear seemed to stay clean .
The kit includes the comb/scraper /brackets and bolts for installation.
Comes with a good diagram of how to install them .
If you do one side at a time you won't loose the adjustment to much .
The comb/scraper does go between the front roller and verticutters . ( I had thought they went the other way at first )
Snug the bolts down till there is a little pinch on the roller shaft . Adjust the scraper evenly in the whillie grooves .
I then held the front roller down and pushed the comb/ scraper till it touched the table top then tighten the hardware and double checking the scraper spacing on the whillie roller .
Looks like when the debris gets thrown ahead it will be wiped of the whillie roller and fall down for the comb to spread out evenly . It should keep the verticute at a more consistent depth through out the process . I'll post our finding when we use them again .
