Stone Construction Equipment Inc. has received a patent from the Canadian Patent Authority for its innovative ProPitch blade adjustment mechanism for the 36-inch, 46-inch and 48- inch Smooth Operator Power Trowels. The heavy-duty ProPitch option is designed to provide nearly infinite yet quick and easy blade settings. The operator can smoothly and quickly adjust the pitch by moving the mechanism along the guide arc. Once released the mechanism locks in place anywhere along the arc for practically infinite pitch settings to finish any stage of concrete, wet or set. ? www.stone-equip.com
