FOAM MARKER STANDARD VERSION
1.0 INTRODUCTION
The use of a foam marking system in certain conditions is benefi cial in
the reduction of spraying operation costs. Missed or skipped areas as well
as overlapping will result in either lost production or over ap pli ca tion of
product resulting in poor weed control, yield loss and/or crop damages.
The standard version of the HARDI
®
Foam Marker is available in either
10,15, or 20 gallon solution tank capacities (20 or 40 gallon on New
Navigator sprayers). It also consists of a Com pres sor Box, In-Cab Control
Box, solution line and an air line plumbed to the foam generator with a
foam dropper at both ends of the spray boom.
The air compressor supplies air to the foam generator and also pres sur -
iz es the solution tank to force foam solution out to the foam gen er a tor.
The Control Box has one switch and one adjustable knob. The adjust-
able knob is for controlling the frequency of foam drops. The switch is for
on/off and alternating foam drops between left and right hand sides of the
spray er.
The standard version of the HARDI
®
Foam Marker is designed to be add-
ed to all current production trailer sprayers as well as some 3 point hitch
sprayers. The installation instructions are covered in this Foam Marker
manual. Some variation from this material may be necessary if installing
on older model HARDI
®
sprayers.
