Paratill® Installation of Delivery Tubes
for Fertilizer and Other Chemicals
This bulletin is provided in response to
dealer interest in equipping the Paratill for application of
fertilizers and other chemicals, including fumigants. We are
providing this information as a guideline for installation of
tubes based on our experience in building custom applicators for
chemical suppliers.
 Find
a supplier of 3/8" tube suitable for brake
fluid. Due to the caustic properties of nematode
fumigants and other chemicals, care must be taken
to use this type of material to minimize
corrosion and eventual chemical loss. Each leg
will require approximately 3 feet of tube.- Cut material into 36"
sections.
- Place the end of the tube
 in a vise and crimp the bottom
end of the tube.
- Weld the end of each tube in
order to seal it.
- Place the tube down the back
of the leg. Tack weld the tube to the lower
portion of the leg (A) and also just below the
bend of the leg (B).
- After attaching the tube to
the lower portion of the leg,bend the tube to
conform to the upper part of the leg. Be careful
not to put a severe bend in the tube, as closure
or cracking of the tube could occur.
- Tack weld the tube to the
upper portion of the leg (C).
- You may tack weld the tube
to the leg in as many locations as you wish,
however, increased welding and heat could weaken
the walls of the tube and produce holes. The
front of the leg will provide protection for the
tube, so we suggest a minimum quantity of spot
welds to hold the tube in place.
- Check with your chemical
dealer for reccomendations of what size to drill
the holes and where to locate them.
- Check the condition of the
delivery tubes regularly. Replace if neccessary.
Follow all product
warnings as issued by the chemical manufacturer.
