Operating Tips Changing Mowing Patterns Creating a Site Survey Change mowing patterns often to minimize a poor after-cut appearance from repeatedly mowing in the same direction. To perform a site survey, lay a 1.25 m plank (4 ft long 2 x 4) on the slope surface and measure the angle of the slope with the inclinometer provided with the machine. The plank (2 x 4) will average the slope but will not take into consideration dips or holes which can cause a sudden change in side hill angle.
After Operation with the mulching baffles installed, the after-cut appearance may deteriorate and the observed power to cut the turf increases. The mulching baffles also perform well for shredding leaves in the fall.
