I installed and worked immediately, but grass caught in the gap with the saw blade and work efficiency fell. Although it may have been able to prevent biting, if it is working with a strong horsepower mowing machine or high revolution, but now it has been removed and is not in use.
Efficiency is good with beautiful grass collection. Since long grass winds up, it may be better to separate the cover from the blade? I like it. Purchased reserve. It is good to look because grass collection is done.
