Applicator tube plugged with
fertilizer.
Disconnect hose at top of applicator tube. Remove blockage
from below. Use finer grained fertilizer, or dry out the fertilizer
if coagulation is the problem.
Low Flow
Augers set to Low Rate
(single-row planters only)
Set augers to High Rate (page 60).
Incorrect Transmission sprockets
Re-check Seed and Fertilizer Rate manual (401-923B).
Exchange DRIVING and DRIVEN sprockets as needed.

Transmission sprockets selected
Apply at a lower speed, or use a new sprocket pair for the
actual rate and speed. Metering (kg per revolution) is lower at
high speeds.
Ground drive wheel slipping
Check lowered tool bar height (page 18). Operate at a lower
field speed. Field conditions may be too wet for reliable meter
drive.
Meter flutes worn
Inspect meter flutes (page 41). Replace as needed.

Augers set to High Rate
(single-row planters only)
Set augers to Low Rate (page 60).

Exchange DRIVING and DRIVEN sprockets as needed.
