Just like the M21P, the M21S is a 12-volt spreader that you can mount on a number of different vehicles easily, and fast! The M21S Professional Broadcast spreader has a Stainless Steel 2” square tube backbone and a 2-pin connection. You can mount the M21S to one of our mounts, or fabricate something yourself. The M21S is a great addition to your ZTR mower, utility vehicle, golf cart, ATV or anything with wheels. Equipped EV-N-SPRED® PRO Dual Port Adjustable Shut-Off technology allows the user to control the balancing of the spread pattern on both the left and right side throwing ports to equal the center and is operated by pulling the spring to close shut-off control to the adjustable stop. The M21 uses a high-torque 12-volt motor, mounted in the hopper and protected by a thermoplastic case to protect it from the elements. The unique Stainless Steel chassis design will not only easily support the 100lb/45kg capacity rustproof poly hopper but also has the quick-connect design. This versatility of the M21S is what makes it the choice of landscaper and turf professionals worldwide.
