1956 Ferguson Vaaljapie TE-F 20 #2

OPERATIONAL INSTRUCTIONS for the FERGUSON TE-F 20 Tractor (Vaaljapie) ....... WARNING Keep a new tractor on light work for fifty hours.

WARNING
Keep a tractor on light work for fifty hours.

Keep the fuel system, fuel storage and handling arrangements scrupulously clean. Do not tamper with the injector pump, governors or injectors. Drive slowly in difficult going. Do not carry anything on the implement. Keep all nuts and bolts tight. This precaution is a general practice with all good operators, who have found that it prolongs the life of the tractor by keeping all parts in perfect alignment. Use an adequate shield to protect the power take-off universal joints. Do not use the draw bar without the drawbar stays. Allow ten seconds to elapse before re-engaging starter if previous attempt at starting has failed.

IT IS HIGHLY DANGEROUS TO PULL ANYTHING FROM THE TOP LINK CONNECTION

YOU HAVE BEEN WARNED

WARNING AGAINST OVERLOADING 
The third gear should not be used with any implement which operates underneath the ground such as a plough, cultivator, etc.

The hydraulic system is designed to operate perfectly in first or second gear but it will not operate perfectly in third gear.

The third gear is too fast for normal implement use. Implements such as ploughs and cultivators, which operate underneath the ground, and which are liable to catch on obstructions, are not designed to stand stresses above 3 m.p.h. (5.6 k.p.h.). It is a fallacy to think that operating in third gear will save the tractor and save fuel for normal work. This gear for normal work would cause overloading, and overloading is disastrous to the life of a tractor.

The third gear is meant to be used for light work only and for implements which operate above the ground, such as a light roller.

A SIMPLE TEST OF OVERLOADING 
With the tractor in motion set the throttle lever about half way open. Then quickly flick the throttle fully open. If the tractor speeds up rapidly the engine is not overloaded—if slowly, the engine is overloaded. These remarks apply to any tractor. The overloading should be remedied at once to avoid serious damage.

When operating up a steep hill the above test might indicate overloading. This is not harmful as it is compensated for when coming downhill.

It is continuous overloading that must be avoided.

Hydraulic Control Lever
When hydraulic pump is in operation, rearward movement of lever raises linkage, forward movement allows it to drop under its own weight.

Starter Switch Safety Button
This must be pressed while gear selector lever is moved forward to operate electric starter. Automatic return when gear lever is moved back to neutral position.

COLD STARTING EQUIPMENT 
The object of this system is to provide pre-heating and priming of the inlet manifold and combustion chambers prior to starting in temperatures below 32ºF (0ºC). An atomised fuel spray is injected into the air inlet manifold by operating the Kigass injector pump located on the instrument panel. The spray impinges on to a heater coil screwed into the manifold, providing a warm fuel vapour to assist firing.

Fig 3 

The Kigass filter (see Fig 3) should regularly be dismantled by unscrewing lever type cap and the filter gauze removed and cleaned.

ENGINE STARTING PROCEDURE (Figs 1 and 4)

IMPORTANT 
Disengagement of the starter pinion is automatic. The gear lever must be returned to the neutral position as soon as the engine fires. If the engine fails to run after firing, do not immediately jab the starter into re-engagement. Always wait at least ten seconds if previous starting attempt has failed.

Before attempting to start the engine, ensure that:-
(a) There is sufficient fuel in the tank.

(b) That all fuel line cocks are open and cut-off control is in starting position.
(c) The clutch pedal is depressed.
(d) The brake is 'on' and the ratchet engaged.

Warm weather, above 50ºF (10ºC)

1. Ensure that the decompression lever is in 'up' position to give full compression for all four cylinders.
2. Depress the excess fuel device located on the injector pump.
3. Move the hand throttle lever to the half-open position.
4. Operate the starter.

Cool weather, 32ºF-50ºF (0ºC-10ºC) 

1. Ensure that the decompression lever is in the 'down' position to relieve compression from all four cylinders.
2. Depress the excess fuel device.
3. Move the hand throttle lever to the half-open position.
4. Operate the starter for two seconds, then, still allowing it to remain in operation, move the decompression lever to the intermediate position, giving pressure relief on three cylinders.
5. Immediately the engine fires, move the decompression lever up to 'full compression'.
6. As soon as all four cylinders have fired, return the gear lever to 'neutral' and set the hand throttle lever at just above 'idling' position to warm up the engine.

Cold weather, below 32ºF (0ºC) 

Warming up (before starting) 

1. Set the hand throttle lever in the half-open position.
2. Pull out fully the fuel cut-off control and lock in this position.
3. Set the decompression lever in the 'down' position to relieve compression from all four cylinders.
4. Hold out pre-heater control switch for 15 seconds to allow the coil to become hot, then, continuing to hold out the switch, give ONE full charge only with the Kigass injector pump, operating sharply to ensure that the spray is fine enough to be ignited.
5. Operate the starter for 10 seconds to allow the hot vapour to be drawn into the engine.
6. Release pre-heater control switch and disengage starter.

NOTE : If the batteries have become discharged, current should be conserved for starting by turning the engine by hand during the warming-up period. This is not difficult, as the engine is fully decompressed. Normally, an additional person is required to use the starting handle, but the procedure can, if necessary, be carried out by the driver alone if the heater coil switch is held out by means of a wedge. The wedge must be removed immediately after the warming-up cycle to avoid further drain on the batteries.

7. Move the decompression lever up to the 'full compression' position.
8. Release the fuel cut-off control.
9. Depress the excess fuel device.
10. Give approximately HALF stroke with the Kigass injector pump.
11. Pull out pre-heater control switch.
12. Operate the starter for ten seconds.
13. As soon as the engine starts, release the heater switch, return the gear lever to 'neutral' position and set the hand throttle lever at just above 'idling' position to warm up engine.

NOTE: If the engine does not start within 10 seconds, do not continue the attempt to start, but five a further warming-up as previously described.

N.B. - The Kigass pump must be screwed back securely after use.

TO STOP THE ENGINE 
Pull the fuel cut-off control under left-hand side of instrument panel, shown in Fig 4. In cases of emergency only should engine be stopped by operating the decompression lever or by turning off any of the fuel taps.

BEFORE STARTING WORK 
Check that engine oil pressure is correct. Ensure that there is an ample fuel supply in the tank for the work in hand.

1956 Ferguson Vaaljapie TE-F 20 #1

HANDLING NOTES for the FERGUSON TE-F 20 Tractor (Vaaljapie) 

The Ferguson TE20 is an agricultural tractor designed by Harry Ferguson. By far his most successful design, it was manufactured from 1946 until 1956, and was commonly known as the Little Grey Fergie. It is light-weight but effective, and a popular collector's item for enthusiasts today. 

Harry Ferguson was born in Ireland in 1884 and at the age of 14 became an apprentice at a car and cycle shop in Belfast owned by his elder brother Joe. This was the beginning of his interest in all things mechanical, including aeroplanes.

He then established his own business selling various makes of cars, took an agency to sell Waterloo Boy model N tractors (the Overtime), and in 1917 the Irish government asked him to tour Ireland to help improve Ireland's tractors - the rest is now history.

HANDLING NOTES for the FERGUSON TE-F 20 Tractor (Vaaljapie)

The following notes have been compiled to assist you to obtain maximum service from your tractor by avoiding inadvertent damage.

CLUTCH OPERATION
Use the clutch only when selecting the gear ratio to be used or to engage or disengage P.T.O. drive. If the load on the engine is goo great for the gear in use, always stop and select a lower gear. Never slip the clutch in order to increase engine speed. Never attempt to change gear when the tractor is in motion. Avoid resting the left foot on the clutch pedal, as this may cause the clutch to slip.

POWER TAKE-OFF SHAFT
The shaft projects from the centre of the rear axle and is enclosed by a removable cap. The operating lever for the P.T.O. clutch is mounted in the left-hand inspection cover of the centre axle housing, as shown in Fig. 5. Movement of the lever towards the rear engages the drive. Engine clutch must be depressed to engage or disengage the P.T.O. drive. Do not run with the drive constantly engaged when the Power Take-Off or Hydraulic Mechanism is not being used.

HYDRAULIC LIFT
As the hydraulic pump is driven by the P.T.O. shaft, the latter must be engaged before the hydraulic system can operate. The hydraulic control lever is situated at the driver's right-hand, as shown in Fig. 2. Rear-ward movement of this lever raises the hydraulic linkage, forward movement releases the hydraulic pressure, allowing the implement to fall. When an implement is in work, the depth at which it operates is governed by the distance that the control lever is moved forward, and an adjustable stop, fitted to the control lever quadrant, ensures that the lever is moved to the same position each time the implement enters work.

The pump has external delivery points for use with implements which incorporate remote pressure operated hydraulic systems, such as the Ferguson High Lift Loader. Before removing plugs (see Fig 5), to connect up implement, make sure the pump is disengaged.

HYDRAULIC PRESSURE RELIEF VALVE
Avoid using the tractor hydraulic system in any way which causes the pressure relief valve, which is internal, to discharge continually. Although this will not actually damage the system, it may cause a slight reduction in the maximum operating pressure.

Where, on later tractors, the Relief Valve is fitted in the lift cover, it is constructed so that, when it opens, all the working parts are lubricated and submerged in the discharged oil, it is therefore desirable for the Relief Valve to be discharged at regular intervals. This can best be effected by an occasional short attempt to raise a load on the lower links greater than the system is capable of lifting.

The maximum recommended load for normal work on all tractors is 1000lbs (453.6kg) a the point of implement attachment on the lower links, and this figure should not otherwise e exceeded.
Warning : Adjustment and inspection of the Relief Valve must be strictly entrusted to an authorised service engineer; unskilled attention to this assembly may result in serious damage to the Hydraulic System.

SAFETY DEVICE
A safety device has been incorporated in the design of the hydraulic system to protect the implement if a hidden obstruction is struck. In this event, the sudden impact has the immediate effect of relieving the effective weight of the implement from the tractor rear wheels, which thereby lose traction and the tractor stops with the rear wheels spinning, without damage to the implement. The tractor can be reversed and the implement raised, then the tractor moved forward before lowering the implement at a point beyond the obstruction.

B. CHECK CHAINS

D. TOP LINK CONNECTION
E. CONTROL SPRING
F. CIRCULAR GROOVE
G. P.T.O. CAP
H. LEVELLING LEVER
J. UPPER LINK ASSEMBLY

LINKAGE TOP LINK CONNECTION
Do not in any circumstances attempt to pull or tow directly from the top link connection or to alter the setting of the main control spring located behind the driver's seat.

On later tractors, adjustment of the upper link assembly is obtained by locating the centre bolt in different pairs of holes in the two members - by this means, the length can be raised between 24½" (622mm) and 26½" (672mm). The shortest adjustment should only be used with certain implements and, in such cases, a precise recommendation will be made.

LOWER LINKS
Remember when coupling implements to the lower links, always fir the left side first and use the levelling lever to assist in fitting the right side. The check chains prevent the implement from swinging side-ways into the rear wheels. It is particularly important that these chains are not twisted and that the chain anchors are assembled correctly with the chain attached above the centre as shown in Fig 6.

The right-hand lift rod is marked by a circular groove, which, when level with the top of the fork into which it threads, indicates that both lower links are level.

ADJUSTABLE DRAWBAR
Normal setting is 18'' (457mm) between drawbar and ground when the lower links are horizontal and the notches in the stays are in line. the height range is between 10'' (254mm) and 23'' (584mm) above ground.

By raising the drawbar, i.e. shortening the stays, traction is increased with trailed machinery. Lowering the drawbar will tend to keep the front end of the tractor down at the expense of some loss of traction.
The height adjustment is particularly useful when working with trailers with high turntables, e.g. four-wheel horse wagon conversions. By raising the drawbar, strain on the turntable is reduced and the line of draft is improved.

When the drawbar is fitted, as shown above, ensure that the hydraulic control lever is locked in the fully forward position by means of the Safety Stop, as shown below :

and that the pump gear is disengaged when the hydraulic mechanism or power take-off is not being used.

When the drawbar is in continuous use, there is a possibility that the working parts of the hydraulic system may become stiff through lack of use. To avoid this, disconnect the drawbar each day and, by operating the hydraulic control lever, raise and lower the linkage several times.

USE OF BREAKS
The combined brake pedal operates the brakes on both rear wheels. Earlier tractors are fitted with a ratchet for parking and later tractors have a brake parking latch.

When the parking latch lever is set forward, the brake pedal is locked down in the position established by the next pressure of the operator's foot and cannot be released until the lever is moved to the rear. Moving the lever forward does not in itself lock the pedal; it ensures, however, that when next the brakes are applied, they remain ''on''.

The independent brake pedals, which are for assisting reduction of the turning circle and operate the brake on the appropriate when only, should never be applied when travelling at high speed, as this can cause excessive stress.

Always keep the brakes in a good state of adjustment. Unbalanced or slackly adjusted brakes can be dangerous and, if binding, will cause rapid lining wear and excessive fuel consumption.
