The SPD-250 bridges the gap between the smaller, utility-related machines and bigger full-fledged padders. It has all the features the SPD-350 has, including sliding cabin with duplicate controls on either side, folding conveyor, and adjustable escalator, but in a smaller frame. The SPD-250 padder is ideal for pipe size jobs from 4 to 16 inches or job sites where accessibility is limited due to transportation or permit constrictions.
