Cost savings was reported by an Illinois home building contractor in the cutting of trenches for foundation footings and is attributable to lower forming costs resulting form the use of a small vertical boom service ditcher equipped with an interesting flaring device. The service ditcher was equipped with an unusual rotation flared cutter operated form a power takeoff on the machine's regular vertical digging boom. A rotating vertical shaft was added immediately behind the regular digging line. At the foot of this shaft was a stirrup-like, trapezoid shaped cutter, rotated by the shaft through a power takeoff form the digging boom headshaft. Operating speed was helped along on this project by leveling the ground with a grader before the footing excavation began.
