Introduction
Thank you for purchasing a Harvest Tec Model 662 Hay Preservative Applicator. This 662 applicator system
has been designed to operate through an Apple iPad (not included) using the Hay App. As well as plug directly
into most tractors that have an ISOBUS Monitor. The 662 Applicator System offers these advantages by
operating though an Apple iPad:
1. Large bright, clear, colorful display
2. More durable and can be read in bright sunlight
3. Wireless connection in cab
4. Can be used for multiple other uses than just the applicator display
5. Option to tie-into the tractor ISOBUS system
The 662 Hay Preservative Applicator System is designed to apply buffered propionic acid to the forage crop as
it is baled and will adjust the rate of application based on moisture and tonnage of the crop being harvested.
This manual will take you through the steps for installing the applicator. If you are unsure about installing the
system after consulting this manual, contact your local authorized dealership for additional assistance. For your
convenience a parts breakdown is located in the back of this manual, contact your local authorized dealer to
order the parts. This applicator is designed to apply AGCO buffered propionic acid.
*iPad Mini or iPad 3rd Generation (2012) or newer, running the current iOS operating system
or one version previous required for iPad option
