The rubber tracks on the Bandit SG 75 expand to 55”, creating an extremely stable platform for grinding. And for transportation and fitting in tight areas, the tracks retract down to 35”, easily fitting through most backyard gates. That means this unit is capable of high production land clearing, but capable as a backyard grinder in residential settings. Also known as a stump remover or stomp grinder or stump shredder or stompgrinder or stumpgrinder or tree grinder.
