Introduction
Read this manual carefully to ensure correct steps are done to attach the applicator to the baler. This
applicator is designed to apply Harvest Tec buffered propionic acid. The model 445, 450 & 451 base kit
includes the following parts: Tank, Frame, Pumps, Hose, Baler Mounted Processor, Touchscreen Display,
Moisture Sensors, and Miscellaneous Hardware. The applicator can be installed on many square balers with
the proper installation kit. Before installing the unit on the baler, make sure you have the proper installation kit.
(See the chart below.) If you are unsure about your installation kit contact your local authorized dealer for
specifications. For your convenience we have included a parts break down for the applicator.
Left and Right sides are determined by facing in the direction of forward travel.
