The Allen MP 235 Edging Rider is a total redesign of the MP 225 edging mechanical drive riding trowel. The MP 235 has rotating guard rings that allow the operator to run along edges of walls, and around columns and pipes to achieve a hard-troweled clean finish. The machine allows the operator to edge within 5/16 inches of the edge of the wall, eliminating the need to hand finish those areas. Standard features include rotating guard rings, manual steering and blade pitch controls, a GX690 air-cooled Honda gasoline engine, and a torque converter clutch system. www.alleneng.com/home.php
