not slip during heavy loads, while cutting grass.
Over-tensioning the belt reduces the life of the
spindle bearing, belt, and idler pulley.
The belt must be tight enough so that it does not
slip during heavy loads while cutting grass, but
over-tensioning the belt will reduce belt and spindle
bearing life.
