BRUSH DRIVE & CONTROL HYDRAULICS
The transmission driven hydraulic pump, located in the differential housing, delivers 5.61 GPM at 1450 engine
RPM. Relief valve pressure is 2500 psi.
The rear axle differential and axle housings are used as the hydraulic reservoir. System capacity is 12 gal.
Pump pressure drives the four scrubbing brushes at 180 RPM at loads to 100 lbs. A directional spool valve
(see Figure 4) allows brush rotation in either direction.
The Ford Tractor hydraulic position control is used to raise and lower the squeegee independent of the
brushes.
The four 18" diameter disc brushes are raised and lowered independently with a separate directional valve
spool. A knob actuated lock-off valve is also provided to prevent leakdown when transporting long distances.

HOW IT WORKS
During the scrubbing process (Figures 9 &10), a solution of detergent and water from the solution tanks is fed
to the solution lines where it is disbursed to the floor through the four scrubbing brushes that aggressively work
to dislodge soilage.
As the machine moves forward, a high vacuum turbine system lifts dirty water and debris from floor surface,
through the squeegee tools and a recovery tank air/water separation system. A float switch in the tank activates a flashing light on the control panel when the water level in the tank becomes too high. Debris and
sludge settle to the bottom of the recovery tank.

HOW IT WORKS
During the scrubbing process (Figures (9 & 11), filtered water from the solution tank is fed to the solution lines
where it combines with the detergent from the metering pumps. This mixture is then fed to the floor where four
disc scrubbing brushes aggressively work to dislodge soilage.
After scrubbing, the used dirty solution is vacuumed from the floor and discharged into the containment
chamber of the recovery tank. Once there a system of baffles helps to clarify the solution on its way to the
pumping chamber of the recovery tank. At intervals, a system of sensors activates the recycling pump which
sends filtered solution from the pumping chamber on its way to the centrifugal separator which aids in further
clarifying of the solution for re-use. In the separator, solids are removed and purged into the containment
chamber. The solids free solution is then fed up through the separator outlet and into the solution tank where it
is ready to be mixed with fresh, metered detergent to be used again as scrubbing solution.

BRUSH LOAD AND BRUSH WEAR
Factors affecting brush wear are type of bristle, bristle, area, and load on the bristles. See your authorized
distributor for the type of brush and bristle most suitable.
Brush load may be adjusted by adding or removing counterbalance springs (see Figure 16). The counterbalance springs are located between the solution tanks and the tractor footrest (see Figure 16). The load will vary
as follows:
No. Of Springs
0
1 per side
23per side

Adding springs will decrease scrub brush load. Shorter brush life can be expected as the scrub brush load is
increased.
SQUEEGEE TOOL FLOOR HEIGHT ADJUSTMENT
The squeegee floor contact height for each squeegee tool may be varied by adjusting the threaded stem on
the caster wheels at the rear side of the squeegee tool assemblies (see Figure 17). Loosen the locking plate
(see Figure 17) and raise or lower the tool position by threading the caster stem up or down in the squeegee
frame threaded bracket.
Load Per Brush
100 lbs.

CHECKING THE ENGINE COOLING SYSTEM
Under some operating conditions there is a tendency for the coolant to boil and be expelled out of the radiator
expansion chamber overflow tube (see Figure 27). Normally, this loss of coolant would be of little consequence, but repeated occurrences can lead to considerable loss of coolant and would be necessitate topping
off the radiator.
WARNING
If the engine has overheated, allow time for the engine to cool before attempting to open the radiator cap.
WARNING
The cooling system operates under pressure. It is dangerous to remove the cap while the engine is warm. To
open the radiator cap while the engine is warm, follow these instructions: use a thick rag and turn the cap to the
first stop and wait for the pressure to escape, then carefully remove the cap.
To check the radiator coolant level:
With the engine cool:
1. Remove the filter cap (see Figure 27, Item 1)
2. Check that the coolant is level with the bottom of the filter tube (see Figure 27, Item 2)
3. If necessary, fill the radiator to the bottom of the filter tube
It is recommended that a solution of 50% water and 50% anti-freeze be premixed with 5% inhibitor and kept
handy as a top off solution.
See the Ford 3930 operator’s manual for more information on coolant capacity, anti-freeze specifications,
clean water properties, and inhibitors.
IMPORTANT
It is essential that a Ford New Holland approved cap is used. If replacement of the original cap becomes neces-
sary, obtain a replacement for your Ford New Holland Dealer.
CHECKING THE FUEL FILTER/SEDIMENT SEPARATOR
Check the fuel filter/sediment separator daily. Water and/or sediment in the glass bowl of sediment separator
indicates the need to drain the bowl and replace the filter if needed (based on interval since the last filter
change).
To drain the sediment separator:
1. Turn the drain plugs counterclockwise (see Figure 28, Item 1) and allow the contaminated fuel to drain.
2. Close the drain plugs by turning clockwise. Check for leaks from the plugs after tightening.

SERVICEING THE AIR CLEANER
The air cleaner consists of an inner and an outer paper element and is located under the radiator cowling.
Periodically squeeze the end of the rubber dust collector (see Figure 32, Item 2). Inspect and replace if
necessary. Clean the air cleaner outer element (see Figure 32, Item 1) whenever the air restriction indicator
light on the instrument panel illuminates while the engine is running. If there is dust inside the outer element it
must be replaced.
IMPORTANT
Clean the outer element only when the restriction indicator light illuminates while the engine is running. Unnec-
essary and too frequent cleaning exposes the elements to handling damage, which could allow dust and dirt to
bypass the filtering process and cause engine, wear.
IMPORTANT
Compressed air, not to exceed 30 psi may be used for cleaning. Blow dust from the inside to the outside by
inserting the nozzle inside the element. Blow loose particles from the outside by holding the nozzle at least 6"
from the element.
IMPORTANT
Do not use water hotter than the hand can stand to wash the element, as the element will be damaged. Never
wash the element with fuel oil, gas, or solvent. Do not oil the element. Rinse the element with clean water from
the inside to the outside to thoroughly loosen all foreign material. Shake excess water from the element and
allow it to air dry.
IMPORTANT
Do not dry the element with compressed air, as the air will rupture a wet element.
To clean the air filter:
1. Remove the filter element as shown in Figure 32.
2. Check the rubber seal on the end of the element for adhesion. If it is loose, install a new element. A
loose, damaged, or missing seal will allow dust to enter the engine, causing severe engine wear.
3. Clean the element by tapping it against the palm of your hand. Do not beat the element against the tire or
a hard surface, as damage to the element will result.
4. Clean the inside of the canister with a damp, lint-free cloth, then reinstall the element.
5. Check and tighten all air induction before resuming operation.

2. Inspect the seal on the end of the element for damage. IF the gasket is damaged or missing, install a new
element.
3. Agitate the element in warm water containing a small amount of non-sudsing detergent
4. Rinse the element with clean water from the inside to the outside to thoroughly loosen all foreign material.
5. Shake excess water from the element and allow to air dry.
6. After drying, check for damage by holding a light inside the element. If an even fine pattern of light is
seen, the element is clean and undamaged. Any large spots of light indicate damage, which requires that
the element be changed.
7. Wipe the canister free of dust, then install the element
8. Check and tighten all air induction connections before resuming operation.
To change the air filter element:
Change the air cleaner element annually, whenever inspection shows the element to be damaged, or after ten
cleanings, whichever occurs first.
To change the air filter element:
1. Remove the filter element as shown in Figure 32.
2. Wipe the inside of the filter canister free of dust.
3. Install the new element.
IMPORTANT
Do not remove or disturb the inner element. IF, after servicing or renewing the outer element, the air cleaner
restriction warning light still does not extinguish when the engine is running then the inner element requires
attention. Authorized Ford New Holland Dealer should only service the inner element.

To drain and flush the engine cooling system:
With the engine cool, drain and refill the cooling system as follows:
Drain the radiator and engine block based on type of coolant used as indicated below.
Plain water - drain, flush, and refill every 6 months, add rust inhibitor
Permanent Antifreeze (regular Ethylene Glycol) - change every 12 months
Long-Life (Ford) Antifreeze - change every 24 months.
WARNING
The cooling system operates under pressure. It is dangerous to remove the radiator cap while the system is hot.
Always cover the cap with a thick cloth and turn the cap slowly to the first stop. Allow all pressure to escape
before removing the cap completely.
IMPORTANT
Alcohol-type antifreeze is not recommended. Do not mix alcohol-type solution with permanent or long-life types
of antifreeze.
IMPORTANT
If plain water is used, be sure to add rust inhibitor to prevent corrosion of the water pump seal.
To drain the system:
1. Remove the radiator cap and open the drain valve at the radiator (see Figure 40, item 1).
2. Open the drain valve at the engine block (see Figure 41, Item 1).

To adjust the fan belt:
Check the condition and tension of the fan belt every 300 hours. If the belt is frayed or cracked, install a new
belt.
WARNING
Never attemp to loosen or tighten the alternator mounting bolts when the engine is running.
To adjust belt tension:
1. Loose the alternator mounting bolts (see Figure 42, Items 1 &2).
2. Pry the alternator away from the engine and tighten the mounting bolts.
3. Check belt deflection by applying 25 lbs. pressure on the fan belt between the alternator and crankshaft
pulleys. An old belt should deflect about ¾”. A new belt about ½”.
To service the alternator:
The alternator (see Figure 42) is belt driven by the fan belt from the engine crankshaft pulley. It is important
that belt slippage does not occur, otherwise the charging rate will be affe3cted. Other than belt adjustment, the
only maintenance required on the alternator is to periodically inspect the terminals and keep them clean and
tight. Also occasionally clean the alternator cooling fan.
IMPORTANT
Do not short the field terminal of the alternator to the ground.
Do not disconnect the voltage regulator while the alternator is running.
Do not remove the alternator without first disconnecting the negative battery cable.
When installing a battery make certain that positive cable is connected first and the negative cable is connected
to the ground. Reverse polarity will destroy the rectifier diodes in the alternator.
When using jumper cables to start your tractor, always connect the positive terminals of both batteries to each
other, and the negative terminals to each other.
To service the voltage regulator:
The voltage regulator is mounted behind the battery. The unit is sealed and cannot be adjusted. If replacement is required, consult your Ford Tractor Dealer.

SERVICE INSTRUCTIONS
To service the battery:
Check the electrolyte level in the battery every 50 hours.
CAUTION
When the alternator is charging, an explosive gas is produced inside the battery. Always check the electrolyte
level with the engine stopped. DO not use an exposed flame and do not smoke when checking the battery.
To check the battery electrolyte level:
1. Clean the top of the battery and remove the vent plugs.
2. Check the electrolyte level. A properly filled battery will have liquid up to the rings on the inside of the fill
wells. In any case the electrolyte level should not be allowed a ¼” above the plates in the battery.
3. If the electrolyte level is low, add distill water. The level is correct when the liquid just covers the ring in the
filter wells, the top of the red shield, or ¼” abovce the plates, depending on the type of battery.
4. Install the vent plug after making sure the breathing holes are not blocked. At below freezing temperature,
be sure to run the engine for a period of time, after adding water, so the battery will charge and prevent
the water from freezing.
Keep the battery connections tight and free of corrosion. Use an ammonia or baking soda/water solution to
wash the outside surface and terminals of the battery. Make sure the solution does not enter the battery. After
cleaning, wash the battery with clear water. Protect the terminals from corrosion with a light application of
petroleum jelly.
In freezing temperatures, the battery must be maintained in a good state of charge. When a battery is discharged or run down, the electrolyte is weak and may freeze, damaging the case. If it becomes necessary to
add water (distilled), it should be done just before using the tractor so the charging will mix the water with the
electrolyte and prevent the water from freezing.
IMPORTANT
Keep distilled water in a clean, well covered, nonmetallic container.
When installing a battery, make certain the positive cable is connected first and the negative cable is connected
to the ground. Reverse polarity will destroy the rectifier diodes in the alternator.
When using jumper cables to start your tractor, always connect the positive terminals of both batteries to each
other, and the negative terminals to each other.
TIRE SERVICE INSTRUCTIONS
Check tire pressure every 50 hours.
Tire inflation pressure:
Front 40psi
Rear 25 psi
When checking the tire pressure, inspect the tire for damaged side walls and tread cute. Neglected damage
will lead to early tire failure.
To service the fuel injection pump:
Consult your Ford 3930 operator’s manual to determine if repairs or adjustments are required. If replacement
of the pump is necessary, consult the Ford 3930 operator’s manual.

BRAKE ADJUSTMENT
If the brake pedal travel becomes excessive, or if the travel of one pedal is not equal to the other, adjust in the
following manner:
1. Disconnect the brake return spring on the right pedal allowing the pedal to drop.
2. Push the pedal down to take up any slack in the linkage.
3. Loosen the lock nut (see Figure 43, Item 2) next to the pull rod nut (see Figure 43, Item 1) and turn the pull
rod nut until the pedal is 1½” to 1¾” below the left pedal.
4. Tighten the lock nut.
5. Disconnect the brake return spring on the left pedal allowing the pedal to drop.
6. Push the pedal down to take up any slack in the linkage.
7. Loosen the lock nut (see Figure 43, Item 2) next to the pull rod nut (see Figure 43, Item 1) and turn the pull
rod nut until the left pedal is level with the right pedal.
8. Check for adjustment be engaging the brake pedal lock. The brake pedal lock should engage easily. if the
pedals are aligned. This will give even braking action, which is particularly important at road speeds.
9. Tighten the lock nut and install both brake pedal return springs.
10. Road test the tractor to make sure the braking action of both rear wheels is equal.
CLUTCH PEDAL ADJUSTMENT
To obtain maximum clutch life, it is essential that the clutch pedal free travel be checked every 50 hours to
maintain free travel at 1¼”. Free travel is the distance the pedal can be moved before resistance is met. If the
pedal free travel is excessive or insufficient, adjust as follow:
1. Loosen the clevis lock nut (see Figure 44, Item 1) and remove the cotter pin and clevis pin (see Figure 44,
Item 3).
2. Turn the clevis to increase or decrease the effective length of the operating rod until the correct pedal free
travel is obtained.
3. Install the clevis pin and secure with a new cotter pin and tighten the clevis lock nut.
4. Recheck the pedal free travel. Readjust if necessary.

To remove the spark plugs:
1. Gain access to the spark plugs by loosening the battery tray wing nut and swinging the battery out.
2. Remove the distributor-to-spark plug wire from the plugs.
3. Remove the high tension wires. Using a spark plug socket, remove the spark plugs and inspect for dam
aged insulators, fouling, and excessive electrode erosion. If serviceable, clean with sandblasting equip
ment.
4. Check the gap with a wire gauge. Adjust the gap to 0.023-0.027".
5. Install the plugs and tighten them to 26-30 lbs./ft.
6. Connect the wires and move the battery back into position.
TO CHANGE DISTRIBUTOR POINTS
Replace distributor points every 600 hours. See your Ford 3930 operator’s manual for detailed service instructions.
TO CHECK THE VALVE CLEARANCE (LASH)
Correct valve clearance is important for good engine performance. Check and adjust the valves every 300
hours. See the Ford 3930 tractor operator’s manual for instructions on setting valve clearance (Lash).
TO SERVICE THE FUEL INJECTORS
The injectors should be checked/cleaned every 600 hours. New injectors are available from your Ford Tractor
Dealer. Consult the Ford 3930 operator’s manual for detailed service instructions.
TO ADJUST THE ENGINE SPEED ADJUSTMENT
Engine speed is set at the factory at 1550-1600 maximum no load rpm. Low idle is set at the factory at 600850 rpm. See your Ford 3930 operator’s manual for adjustment instructions.
