Introduction
Thank you for purchasing a Harvest Tec Model 664 Hay Preservative Applicator. This 664 applicator system
has been designed to be operated through an Apple iPad (not included) using the Hay App. As well as the
option to plug directly into most tractors that have an ISOBUS Monitor. The 664 Applicator System offers these
advantages by operating through an Apple iPad:
1. Large bright, clear, colorful display
2. More durable and can be read in bright sunlight
3. Can be used for multiple other uses than just the applicator display
4. Option to tie-into the tractor ISOBUS system
This manual will take you through the steps for installing the update to the automatic applicator. If you are
unsure about installing the system after consulting this manual, please contact your local authorized dealership
for additional assistance. If you are in need of parts for the system please see the parts breakdown in the back
of this manual and contact your local authorized dealer to order the parts. This applicator is designed to apply
Harvest Tec buffered propionic acid.
Right and Left sides are determined by facing in the direction of forward travel.
