Bandit ZT1844 Track Stump Grinder Bandit Industries’ Model ZT1844 stump grinder is the most productive compact, track mounted stump grinder on the market. It features all the power and performance of every Bandit® stump grinder, but with features that make it an ideal machine for rental companies or dedicated stump grinding professionals. The wider swing arc covers more area when grinding at the stump. The taller grinding height and deeper grinding depth means you can tackle larger stumps and chase the roots deeper into the ground. And intuitive controls and zero-turn manoeuvrability make grinding stumps easy, no matter if you’re a seasoned professional or a rental customer.
