The NITRO spreader from Tubeline originally started with the 450, 600, and 750 models followed by the 950 model shortly after the initial product launch. Developed with features to ensure commercial readiness these spreaders offer slip slide poly board floors and walls, a guillotine endgate, reversible apron chain, and quick drop beaters. Engineered for commercial use, our commercial line are all scale ready. The guillotine endgate can be held in any position controlling how much material is able to be moved to the beaters by the variable speed apron chain. This method of delivery provides consistent metering whether working with pen pack or semi-solids.
