The New Leader MultiBin attachment transforms the L4000G4 single hopper spreader into three hoppers. The front two hoppers dispense fertilizer products while the single hopper at the rear dispenses micronutrients or seeding products. The micronutrient hopper can also be split to create a fourth hopper. The large capacities of each hopper section allow users to cover more acres, reduce fill time while increasing productivity and maintain an accurate spread pattern. Constructed of 304 stainless steel to prevent corrosion, the MultiBin is specifically designed for new L4000G4 spreaders, but will retrofit into a previously purchased L4000G4. A few features of the MultiBin include an optional micronutrient cover that opens and closes with a stainless steel air cylinder; low-bin sensors in each bin to know when to refill, and simple installation and removal from the L4000G4 for fertilizer and lime spreading.
