Anytime you put on new cutting parts it helps. the Crary system works fine. I have not found it will increase your speed over what the oem stuff does when new. The Crary does have the adjustable hold downs with the plastic tabs. These work well but the tabs will leave on rare occasions, get a few extra. The SCH system requires the least amount of maintaining I have found. To increase speed the angle of attack i.e. tilting the cutterbar to make the tips closer to the ground and increasing the strokes _ min are the only thing that will really increse ground speed and still do a nice job of cutting.
