Leveling Sprayer
Refer to Figure 13
Check and adjust this only when hitched on level ground.
For proper tank drainage and correct boom height con-
trol, the tank mainframe must be sloped forward in oper-
ation at an angle of:
one to two degrees (1-2 °) .
ASAE standards call for the top of the tractor drawbar
to be 13 to 20 inches (33 to 51cm) above ground.
Using a level, and yardstick or meter stick, check along
the tank frame. The forward end of the measuring stick
would be lower than the back end by:
yardstick:
3 ⁄
4
in
meter stick: 2cm
Level may be adjusted either at the hitch, or at the
tongue-to-frame joint
(or both).
If a PTO pump is present, the hitch height adjustment
range may be limited. If adjustments are made for PTO
alignment, level needs to be re-checked, and may need
adjustment at the tongue-mainframe joint
.
Hitch Height
With a hydraulic pump sprayer, make leveling adjust-
ments at the tractor hitch (if possible). Keep the tractor
drawbar height within the ASAE recommended range
(13-20 inches, 33-51cm).
With a PTO pump, make leveling adjustments at the
hitch, but only if:
• both drawbar height ,
• PTO output to drawbar spacing can be kept within
recommendation - and
• the PTO input at the bearing mount (see Figure 11 on
page 24) can be kept at or slightly above the height of
the PTO output.
