Difference Between 9N Ford Tractor and 8N Ford Tractor (With Table)

Harry Ferguson was the person who implanted a seed of an idea into Henry Ford’s mind about the new possibilities of Ford Tractors. Ferguson first demonstrated his Tractor in 1938, which left Ford impressed with its design, of three-point hitch system. Later the Ford Company invested 12 million dollars to finance Ferguson’s new distribution company. This investment led to the first Ford tractor, which became an industry standard, the 9N Tractor. With its success came the 2n and 8N. 

9N Ford Tractor vs 8N Ford Tractor

The main difference between 9N Ford Tractor and 8N Ford Tractor is that 9N is the older model released and 8N Ford tractor is the latest model, with an almost eight-year gap between them, 1939 and 1947, respectively. Another difference is that 8N Ford tractors are generally more potent regarding engines than the 9N Ford Tractors. 

The first Tractor to ever be acclaimed as an industry standard, the 9N Ford tractor, is the first to have the Ferguson three-point hitch system and rear power take-off. The advantage for the building of this Tractor was that it sold for 585 dollars initially, whereas other tractors were almost twice its price. 

The latest model of the Ford Company is the 8N Ford tractor, with more success than the 9N Ford tractor. It ranks at the top among the tractor selling competitors of all time. Ford tractors with a clutch on the left side were never inserted before this model. Along with this it comes with a dedicated right break. The rapidly spiked 8N Ford tractor was much more in demand than the 9N Ford tractor.

What is 9N Ford Tractor ?

The 9N Ford Tractor has been a first in many things, with its variable front track proving to be quite a valuable crop cultivation. Easier crop cultivation has been made possible with the help of front half-axles that can slide in and out. And can also be pinned in place—also having a variable rear track, with the reversible offset of the rear wheel design.

In a fashion unique to Ford, the exhaust underneath the Tractor has been routed similarly to an automobile. At the Tractor’s behind, a PTO is placed, by which A PTO driving the three-point or towed implements are made more accessible. The Ferguson system has been quite invaluable to fix problems occurring in the previous Ford son tractors, such as not limited to tilting and flipping over if the plow hits an obstruction on its path.

Another thing that only the 9N Ford Tractors were the first in was that the US Navy used these tractors onboard their aircraft’s carrier for towing misplaced aircraft and had earned a nickname, the “Moto Tug.” The 9N original engines used to be powered by distillate fuels. The engine shares similarities with the Ford V8 automobile’s same bore and stroke sizes. 

What is 8N Ford tractor?

The 8N Ford tractor has had plenty of changes from the 9N Ford tractor, including PTO increase. In addition to that, the drawbar horsepower is also expanded.These changes were deliberately done in order to help the tractor adjust to various soil types. Another reason was that Harry Ferguson has the license over the mechanism of the hydraulic system. Thus, the 8N Ford tractor was able to evade possible lawsuits. Still, the problem occurred when it malfunctioned in case of some tools.

The draft control went through the improved position of controlling. As a result, the implement was forced to stay unchanged in a position. But, the drawback of these Tractor series was that they had no live PTO. 

As a result, some other parts, like the brush cutters had no means for saving the internal energy thereby leading to further problems. Thus, as the driver disengaged the clutch, the Tractor would abruptly move forward. But there was a plausible reason, for it could override the coupler in this model. The good thing was that a new change in 1950 was made, with a Proof meter (combined speedometer, tachometer, hour meter) located on the lower right portion of the dash.

Main Differences Between 9N and 8N

  1. The louvered board, a series of overlapping, sloping panels present in an opening, arranged as to admit air but to exclude rain or cut off visibility from the outside, is present in 8N Ford tractors. But, for 9N Ford Tractors, the air ventilating factors, louvered boards, are absent.
  2. The 9N Ford Tractors have plates with the last number of the Tractor’s founding year (1939) with the product character given to each Tractor (N). But, for “8N” the plates cannot be written with the founding year (1947) number due to 2N and 8N having the same plate number. So, to know the exact tractor, a tractor’s model list is required.
  3. 9N Ford Tractors have foot pegs present, while the 8N Ford tractors have running boards/foot pegs depending on the model.
  4. 9N Ford tractors have a front mount distributor, while the 8N Ford tractors could have a front or side mount distributor.
  5. There is a severe absence of these in 9N Ford tractors for position control and live hydraulics, but the 8N Ford tractors have both above present.


Both the 9N Ford tractor and 8N have their pros and cons but compared to 8N, the 9N Ford tractor is a little bit too old and less advanced. With higher speed transmission, improved panels, comfortable position of the brakes, and sensible layout, the 8N, to this date, is the much preferable choice.

Even with its initial hype, the 9N Ford tractor couldn’t live up to its glory. With facilities quickly adapting to the agricultural conditions, mainly soil, the 8N has got it done. Even with the 9N Ford tractor and 8N Ford tractors being reliable, the 8N, with new additions, is the best option for the job.
