The pre-bedder is typically used to form/fumigate and the layer (typically RMC-372R or RMC-360R) follows with the drip and plastic. This process has proven to be the most efficient.
RMC-372PB/RMC-360PB
These two pre-bedders are used in front of our conventional three row rigid layers to pre-form and incorporate fumigants into the beds in front of the rigid layers. They consist of a tool bar with three sets of gathering blades and three press pans. These usually are outfitted with fumigation knives which are optional. The 372PB is for 72” centers and the 360PB is for 60”.
