VALMAR Operation
Page 11
4 - Operation
Your Valmar applicator is designed to efficiently broadcast seeds and granular chemicals.
As noted in the diagram below, the system operates by using a hydraulically (optional gas engine)
powered fan to blow product through an air delivery system. A grooved metering roller accurately
meters product from the hopper into the venturis. Air passing through the manifold and venturis draws
the product into an airstream and sends it down a distribution hose where it can be spread by a
deflector. Product application rate is controlled by a sixty speed gearbox driven by a metering wheel in
contact with the ground.
Figure 4-1: How the System Works

Operation VALMAR
Page 12
Safe Operation
Efficient and safe operation of the Valmar
Pneumatic Applicator requires that each
operator reads and understands the operating
procedures and all related safety precautions
outlined in this section. A pre-operation
checklist is provided. It is important for both
personal safety and maintaining the good
mechanical condition of the Applicator, that this
checklist is followed.
Pre-Operation Checklist
Before operating the applicator and each time
thereafter, check off the fallowing areas:
1. Check the implement and applicator
hydraulic system. Ensure that the
hydraulic reservoir in the tractor is filled
to the required specifications.
2. Inspect all hydraulic lines, hoses, fittings
and couplers. Use a clean cloth to wipe
any accumulating dirt from the couplers
before connection to the tractor’s
hydraulic system.
3. Inspect all delivery hoses for any wear
and restrictions. Repair or replace if
necessary.
4. Inspect the hopper for accumulation of
any foreign material that could plug the
venture system.
5. Check all the chains, sprockets, belts
and pulleys for proper adjustment and
tension. Adjust as shown in the
Adjustment and Service section of
manual.
6. Check the fan and manifold for any
accumulation of straw of dirt. Clean as
required. Run the fan at field speed to
clear hoses and outlets of foreign
material.
7. Check the metering rollers. They must
turn easily. Worn rollers will alter rates.
8. Ensure that all bearings turn freely.
9. Inspect the gearbox for alignment and
proper lubrication. Refer to Adjustment
and Service section of manual.
10. Operate the electrical clutches for proper
engagement. Refer to Adjustment and
Service if clutches do not work properly.
11. Make sure that all guards and shield are
in place.
12. Check the ground drive tire pressure.
Inflate to 30 psi.
13. Check mounting hardware for hopper to
implement. Tighten where necessary.
Control Unit (Figure 4-2)
The applicator is equipped with an electrically
operated control unit. The unit allows selection
of left, right or both metering rollers as well as
normal or alternate rates of product application.
The control unit also indicates incorrect
manifold pressures. Refer to Assembly and
Installation Manual for control unit installation.
Power Switch
Push the power switch to “ON” position for
operation of control unit. A light above the
switch indicates power is on.
Selector Switch
Select BOTH for the operation of both metering
rollers for full width application of product.
Select LEFT or RIGHT when only half the
application width is desired. This is useful when
finishing a field or where overlapping may occur.
Green lights above the dial indicate which
option is selected.
Normal/Alternate Rate (Optional)
If an alternate rate kit is installed, either a
NORMAL rate or an ALT (alternate) rate can be
selected and switched from one to the other at
any time. The desired alternate rate must be
determined when purchasing the kit according
to the following chart:
Alternate Rate Sprockets
No. of Teeth % Change in Rate
12 40% Lower
14 30% Lower
16 20% Lower
18 10% Lower
22 10% Higher
24 20% Higher
26 30% Higher
28 40% Higher

VALMAR Operation
Page 13
The green light indicates NORMAL rate and the
yellow light indicates ALT (alternate) rate.
Assembly procedures are contained in the
alternate rate kit itself.
Pressure Alarm
The red ALARM light and buzzer alerts the
operator to inadequate or excessive air manifold
pressure. The light and buzzer are activated by
the manifold pressure gauge. Refer to Manifold
Pressure Gauge in the Operation Section.
Figure 4 - 2: Control Unit
Manifold Pressure Gauge (Figure 4-2)
The manifold pressure gauge indicates proper
fan speed by measuring air pressure in the
manifold in inches (cm) of water column. The
pressure gauge includes a low pressure contact
set at 10 inches and a high pressure contact set
at 25 inches. The gauge is wired to the pressure
alarm light on the control unit. The pressure
alarm light will light up for two reasons:
1. The air pressure is below 10 inches.
2. The air pressure is above 25 inches.
Proper fan speed is achieved at a manifold
pressure of 17 inches of water column. Fan
speed is set by adjusting the speed of a gas
engine or a hydraulic motor which drives the
fan.
Figure 4 - 3: Pressure Gauge
Gas Engine Fan Drive (Optional)
The 2055 can be equipped with a 9 hp Honda
engine. The 2455 and 3255 can be equipped
with an 11 hp Honda engine.
Refer to the Honda Owner’s Manual for correct
startup and operation of the engine.
The engine is equipped with centrifugal clutch
that engages at 1600 rpm. Below that speed the
fan will not operate.
Hydraulic Fan Drive (Figure 4-4)
Operation of the hydraulic fan drive requires an
oil flow of 10.5 U.S. gpm for the 2055 and 2455,
and 11.5 U.S. gpm for the 3255.
The major components of the hydraulic fan
drive are:
1. the hydraulic motor for operating the fan.
2. The flow control valve for adjusting fan
speed.
There are two basic tractor hydraulic systems:
the Open Center system and Closed Center
System. Contact your tractor dealer to establish
which system you have. Set your fan speed as
follows:
