Tank Straps
Refer to Figure 56
The tank straps that wrap around the sprayer tank may
become loose after the first few hours of operation. This
occurs when the tank settles in the saddle. Polyethylene
tanks are especially susceptible to this. Retighten the
tank straps to secure the tank.
Shear Bolt
Refer to Figure 56
Your Great Plains sprayer is equipped with four shear
bolts
, two each side, to help prevent damage to the
booms. These are located at the inner boom pivot posts
at the ends of the center section. When the boom
encounters an obstruction, both bolts on that side fail,
allowing the boom to swing back.
If a pair of shear bolts breaks, replace them with a pair of
5 ⁄
8
-11 x 3in Grade 5 bolts (Great Plains part 802-160C). If
this size and grade bolt is not immediately available, you
may temporarily substitute metric M14x2 Class 8.8 bolts.
Using a lower grade/class bolt causes nuisance shears.
Using a higher grade/class bolt may result in serious
equipment damage.
Inspect these bolts at the start of the spraying season to
insure the bolts have not been weakened through use or
rusting.
Stock a spare nut for each spare shear bolt, as the nut
end of the sheared bolt commonly falls away and is diffi-
cult to locate.
