For the first kit listed, the hydraulic end gate hydraulically raises and lowers to help keep loose and semi-liquid material in the spreader during transport and loading on the MS11 Series Manure Spreaders.
For the second kit, the variable-speed hydraulic drive with four-hose hookup allows the end gate and apron to work independently on the MS12 Series Manure Spreaders. This conversion kit requires two selective control valves (SCVs).
For the third kit, the variable-speed hydraulic drive with two-hose hookup allows the apron chain to begin moving once the end ate is fully raised on the MS12 Series Manure Spreaders. This kit requires only one SCV.
For the fourth kit, the electric variable-speed hydraulic apron control allows control of the apron speed to be done from the operator's station with electric controls versus manually on the MS12 Series Manure Spreaders.
