Shear Bolt Replacement
Your Great Plains sprayer is equipped with shear bolts to
help prevent excessive damage to the booms. These are
located at the inner boom pivot posts at the ends of the
center section. If the shear bolts breaks replace it with a
5/8” x 3 1/2” grade 5 bolt for 80 and 90 ft. booms or a
1/2” x 3” grade 5 bolt for 60 ft. boom. Using a different
grade bolt will cause premature failure. It is recommend-
ed to replace these bolts at the start of the spraying
season every year to insure the bolts have not been
weakened through use or rusting.
Storage
1. Empty solution from the tank, clean the chemical in-
ductor {if included}, and store or dispose of the
chemical as recommended by the manufacturer’s
chemical label.
2. Flush the entire sprayer system with clean water.
3. Clean out Whirlfilters ® . Refer to "Operating Whirl-
filter ® " on Page 27.
4. Circulate 3 - 5 gallons of antifreeze {Great Plains
strongly recommends the use of recreational vehicle
antifreeze} through the system including the pump,
hoses and nozzles. Drain the sprayer and properly
dispose of antifreeze. It is advisable to remove the
pump and store it in a warm, dry environment during
the winter.Regular antifreeze is harmful or fatal to
animals and humans. Use carefully according to the
label’s instructions. We strongly recommend the use
of recreational vehicle antifreeze which does not ex-
hibit these harmful side effects.
5. Remove nozzles, disconnect the control box, and
place them indoors with the pump.
6. Change filters in the tractor cab after finished.
7. Wash off the exterior of the sprayer thoroughly using
a safe solvent or soap and water.
8. Inspect all parts of the sprayer for wear and rust. Re-
pair and paint parts as necessary.
9. Store the sprayer in a dry area away from direct sun-
light.
