Clutch utilizes two centrifugal clutches the starter clutch system to drive the sheaves of the drive primary clutch What that means is that the belt can remain tight in the sheaves and that both the sheaves and the belt are stationary while the vehicle is idling This eliminates the belt wear at an idle and during start up while also providing one additional form of belt protection The centrifugal clutches starter clutch can act as overload protection as well cases where too much torque is trying to be transmitted to the belt the centrifugals can slip before the maximum load on the belt is achieved What this means is that instead of the belt slipping on the sheaves during an overload the centrifugals will first slip further protecting the belt from damage PAGE 36 HHXG5 RIDE ON TROWEL OPERATION MANUAL REV 1 10 25 10 MAINTENANCE TROWEL Blade Pitch Matching Blade Pitch for Both Sets of Blades Sometimes it may be necessary to match blade pitch between the two sets of blades There are some signs that this may be necessary For example the differences in pitch could cause a noticeable difference in finish quality between the two sets of blades or the difference in blade pitch could make the machine difficult to control This is due to the surface area in contact with the concrete the blade set with the greater contact area tends to stick to the concrete more Single Pitch On a Single Pitch tro
