Reply To: Motor Triple mowes bad

To back lap properly use a water based paste , not oil based as in valve grinding paste. Water based so that when done you can hose it off and get rid of every trace before rotating the cylinders in the cutting direction. Leaving a trace of paste “ undoes” some of the sharpening effect gained by the back lap. In an ideal world neglected cylinders should be relief ground to create some space to retain the paste during back lapping. Applying paste to well worn cylinders results in much of the paste being thrown off before it can get to work.
A Motor Triple with four bladed units will deal with quite heavy cutting but to get a good finish reduce the forward speed to increase the clip rate aka cuts per yard. There is an art to obtain a good finish with commercial powered cylinder equipment and even more skill required in using wheel driven gang mowers.
