A unique feature of the commercial series is a "Quick Adjust" height control system. Without the use of tools, the cutting height can be changed from 1.27 to 7.62 cm in 0.63 cm (1/2 to 3" in 1/4") increments in seconds. This system is linked to a full width aluminum rear roller that will stripe all types of turf. The fully adjustable spring loaded reel unit reduces the possibility of damage to the reel from debris. This also allows for a quick and precise adjustment of the reel to bedknife.
