John Deere Model A Tractor
John Deere Model A Tractor
Many Journal readers rely solely on horse or mule power. Quite a few use only tractors and a whole ‘nother bunch prefer to combine power sources. A small group of farmer folk keep an old tractor around soley for belt power for such things as stationery threshing machines. A popular model for such jobs is the John Deere Model A tractor showcased in this article. The information we have is extensive, we are presenting just a small portion.
Clutch lever, throttle, fuel control and radiator shutter control are reached easily from the operator’s seat. Under your feet are the brakes, hydraulic power lift foot control pedal, and a large, comfortable platform on which you can stand if you so desire.
Familiarize yourself with all the controls provided for safe and easy operation of your new tractor. Regardless of your previous tractor experience, study this section covering controls carefully before you operate your tractor.
The large, bucket-type seat is high up and well forward. You are generally out of the dust where you have a clear, unobstructed view of your work.
The seat (and seat standard) ride on a coil spring that can be tightened or loosened to conform with the operator’s weight for improved riding comfort. When working on rough ground or for heavy operators, more compression should be applied to the coil spring.
Whether you are tall or short, the seat can be adjusted backward or forward to a comfortable position by means of seat attaching bolt located directly under the seat.
Due to the high, centered seat location, tapered fuel tank, and narrow, streamlined design, you can easily see what you are doing at either side. This design, coupled with a steering mechanism built to eliminate entirely objectionable wobble, backlash, or whipping of the steering wheel, even in the roughest going, permits you to work in freedom and comfort.
Smooth, responsive steering can be maintained throughout the life of your tractor by means of the adjustments provided for this purpose.
Adjustments can be quickly and easily made by your John Deere dealer’s serviceman.
SHUTTER AND FUEL CONTROL WITH HEAT AND OIL GAUGE
The temperature of the tractor is effectively controlled from the driver’s seat by means of a manually operated radiator shutter.
The engine temperature gauge is located in plain sight of the operator and indicates when to adjust the shutter.
For best operation, the engine should always be operated up to its proper temperature, which is 190°F. registered on heat indicator. This results in greater all-around economy, better lubrication and more power.
A convenient, three-way fuel control lever, located on the instrument panel, enables the operator to switch from gasoline to low-cost fuel or to shut off the fuel supply entirely without leaving his position at the wheel.
Also located on the instrument panel is the oil pressure gauge. This gauge does not in any way tell the amount or condition of the oil in the crankcase. It only indicates whether the oil pump is working. The indicator hand of the gauge should rest between the letters “M” and “H” when the engine is running fast idle. If pressure is not registered on the oil gauge when the engine is started, stop the engine immediately.
When starting the engine, set choke in full choke position. (On tractors equipped with electric starters, choking is accomplished by a button, mounted on the instrument panel.) On tractors not equipped with electric starters, choke lever is on the carburetor.
Over-choking or excessive use of the choke will flood the engine, causing hard starting.
Hand Cranking: The flywheel method of starting is simple, safe, and easy. You simply grasp the flywheel and roll it forward slowly.
All controls are within easy reach.
Electric Starting: To start the tractor, pull choke, and step on starter lever.
The starter motor is geared into the flywheel which is protected by a guard.
Individually foot-operated differential brakes makes possible short turns to right or left at the row ends.
If the brakes are pressed simultaneously with both feet, they assure you safe stopping at high transport speeds.
A brake latch is conveniently located for locking each brake when doing belt work or when stopping the tractor on a hill or incline.
The power required in putting the tractor in motion is gradually and smoothly applied to the drive system by slowly pushing the clutch lever forward. As the tractor picks up speed, give the lever a quick forward thrust until the clutch snaps into engagement.
By pulling back on the clutch lever, the clutch is released and the engine disconnected from the transmission. The pulley brake, which is a part of the clutch lever, stops the pulley from rotating, permitting easy shifting of the transmission gears.
