Sprayer Attaching and Removal
Tractor approached at an angle to
the main frame of the sprayer
attachment and the holes are
slightly off center.
Back away from the sprayer
attachment with the tractor.
Adjust the approach and try
picking up attachment again.
27
The tractor header cylinders have
not been fully extended.
Fully extend tractor header
cylinders when the tractor is
positioned in the sprayer
attachment legs.
27
Tractor header forks not aligned
with holes when the forks are
positioned in the sprayer
attachment legs.
The boom props have sunk in soft
soil and now the boom
suspension is no longer slack.
Reduce the tension in vertical
suspension by loosening the nut
on the draw bolt. After sprayer
attachment is secured, adjust
clevis to the previous length.
66
Hydraulics
Vertical boom lift cylinder seal
leaks.
Seals are ruined and must be
replaced.
Remove cylinders by
disconnecting and pulling out the
top of the mast. A lifting device
of at least 20 feet must be used.

Micro-Trak MT-3405
Rate Controller
Refer to the Micro-Trak MT-3405 Operator’s Manual for trouble shooting and
information on maintenance and service.
Sprayer output does not match
calculated application rate.
Operator is accelerating and
decelerating the windrower
erratically, resulting in uneven
output.
Adjust the speed control lever
slowly and consistently to allow
the monitor 5 to 10 seconds to
adjust to the spray rate.
54
The nozzle tips selected for the
application are not correct.
Check the nozzle tip selection.
Ensure the application rate and
speed match the desired
application rate.
55
The rate controller displays a
reading that fluctuates rapidly and
erratically during spray application.
The servo valve cannot control
the flow to the booms because
sprayer pump output is too great.
This may occur when the
hydraulic oil is heated to
operating temperature or the
outside temperature increases.
Reduce the flow to the sprayer
pump by turning the reel speed
and conveyor speed dials until
the rate controller readings
fluctuate normally. Ensure the
nozzle pressure is matched with
the application rate for the
selected nozzle tip and
application speed.

NOTE: Always wash the outside of the sprayer and rinse the spray system with clean water prior to
working on the sprayer.
