The Focdson Tractoc-Coil Box: Side-Plate No.3 THE 37 magneto allows the current to Bow through the metal parts to the metal roller in the commutator. Therefore, when the commutator roller in revolving touches the four commutato~ contact points, to each of which is attached a wire connected with a coil unit, an electrica'l current is passed through the entire system of primary wires. This circuit is only momentary, however, as the roller passes over the contact point very rapidly, letting the current Bow into each unit as the roller touches the contact point connected with that unit•. The commutator should be kept clean and well oiled at all times. What about the Spark Plugs? Answer No. 77 One is located at the top of each cylinder and can easily be taken out with a spark plug wrench after the wire connecti-on is removed. The high voltage current Bows from the secondary coils in the coil box, and in reaching the contact points in each spark plug it is forced to jump a n of an inch gap, therefore forming a spark which ignites the charge in the cylinders. If the spark plugs become carbonized or sooted, the high tension current instead of jumping between the points of the spark plugs will pass through the carbon accumulation directly to the metallic shell. This will cause the cylinder to misfire. When in this condition the plugs should be removed and cleaned. (See Answer No. 39.) . What are the indications of Ignition trouble? Answer No. 78 The uneven sputter and bang of the exhaust means that one or more cylinders are exploding irregula!'ly or not at all, and that the trouble should be promptly located and overcome. Misfiring, if allowed to continue, will in time injure the motor and entire mechanism. A good driver will be satisfied only with a soft, steady purr from the ex­ haust. If anything goes wrong. stop and fix it immediately if possible. How can one tell which Cylinder is Missing? Answer No. 79 This is done by manipulating the vibrators on the spark coils. Open the throttle until the motor is running at a good speed, and then hold dO\\"Il the two outside vibrators (No. 1 and No.4) with the fingers so they cannot buzz. This cuts out the two corresponding cylinders (No.1 and No.4), leaving only No.2 and No.3 running. If they explode regularly it is obvious the trouble is either in No.1 or No.4. Relieve No.4 and hold down No.2 and No.3, and also No.1; if No. 4 cylinder explodes evenly it is evident the misfiring is in No. 1. In this manner all of the cylinders in turn can be tested until the trouble is located. Examine both the spark plugs- and the vibrator of the missing cylinder.

The Magneto-Plate No. 22 When the Magneto get. out of order-What? Answer No. 85 The magneto is made of permanent magnets and there is very little likelihood of their ever losing their strength unless acted upon by some outside force. For instance, the attachment of any electrical battery to the magneto terminal will demagnetize the magnets. Should this occur, it is not advisable to try to recharge them but rather instali a complete set of new magnets. When using an electric battery for starting, be sure and disconnect the wire from the primary contact terminal. The new magnets will be sent on a board in exactly the same manner as they should be when installed, so they will not stick together when in position on the . Great care should be taken in assembling the magnets and lining up the magneto, so that the faces of the magnets are even and are separated from the surface of the coil spool by j~ of an inch. The magneto is often blamed VII~· ;n the trouble is a weak current caused by w.!ste or other foreign matter accumulating 1.Ulder the magneto contact spring, which is .

Neither the beginning of Fordson production nor the end of it had a really big impact on the change in horse and mule numbers. It remained a gradual transition process for several decades. The Fordson may have started the mechanization of U.S. agri­ culture, but other tractors played as big, or bigger, role in the transition process. The Fordson had been gone for many years before that transition finally ended. But there is no doubt that the Fordson almost completely dominated the U.S. tractor industry during most of the 1920's. Ford claimed over 40 per­ cent of the U.S. tractor market for the 1921-1927 years. The Fordson still had over 55 percent of that market in 192 7, the last year it was built in the.
