Chrome parts were changed to painted and some factory improvements continued to be introduced. It only takes a few minutes to determine a general range of value for just about anything. This photo shows a model 850 800 series with serial 93706 1956. Your Needs Are Our Priority When it comes to customer satisfaction, we at Steiner Tractor Parts don't hesitate to go above and beyond to help you. Some casting codes on 9N-2N-8N engine blocks, transmission housings, and rear axle housings can also help pinpoint a date of manufacture. Also at serial number 109503 the front steering arms and spindles were changed to a keyed design.
The 9N and later 2N tractors were painted all gray. It can now be flipped forward for access and stays attached so it won't get lost. The Ford N-Series tractors were very successful. Most people still refer to these tractors as 9N's. The brake system was improved and made easier to service by the addition of removable drums.
Unfortunately, only an enthusiast can afford to keep a vintage gas engine in good tune so it stays reliable. Small revisions that don't affect compatibility - such as a change in suppliers - usually result in the suffix changing on the service part number to indicate the design change level. At serial number 42161 the engine block casting was changed for better cooling around the valve guides. At serial number 109503 the 9N radiator was replaced with new 2N radiator which was slightly smaller and was pressurized to 4 psi to increase the boiling point of the coolant. This indicates the part was originally designed for a 1968 Mercury, and illustrates how parts crossed over from one line to another, across divisions, and the equipment provided on a particular vehicle often determined that different parts were used. Paying for maintenance on a vintage gas engine makes any diesel a better value for a working tractor. Serial numbers on the 9N-2N and 8N tractors are located on the left side of the engine block, just below the head and behind the oil filter.
The steering box was changed at serial number 216989 to a Spicer type with tapered sector shafts for better backlash adjustment. In most cases my value estimate will go negative. The average, non-running, field ornament, can often be hauled away free-of-charge. It allows shifting up or down on the fly with no clutch. Which ran through ~490000 in 1975. I googled it until I was googly-eyed. A code such as G187 would mean the part was cast on or after July 18th, 1947.
At serial 179073 the oil filler tube was shortened. Position control, a much needed feature on the 3 point lift, was added to the hydraulic system. They worked much better than the early ones. You will only see the diamonds on 8N tractors with a serial number after 8N 433578. Perhaps some pics of the beast? A longer oil line was added to route the return oil from the oil filter through the governor for added lubrication. The camshaft and head were upgraded between serial number 70000 and 85000.
It can be difficult to determine if a tractor is all original. This could mean revisions to the part or multiple manufacturers supplying the part to Ford. At serial 111758 the 4 blade fan became standard and the 6 blade fan became optional. Please remember, there are differences in the official Ford documents we can find. Ford tractors increased in size and horsepower with more different model types and options introduced each year. It is unclear why Ford didn't change the serial number prefix to 2N. A safety interlock starter button was introduced at serial number 9N12500.
Try different angles and light sources to make the number visible. I found one old thread on a tractor forum where the responder was sure that the K correlated with a model 3550, but that's all I could find. Full-length running boards were added and both brake pedals were moved to the right side. In late '54 Ford introduced the new expanded line up of the hundred series tractors for '55. Ford Motor Company changed the model designation only when it was felt a new model was needed. Also note the upper spindle steering arms. Many people don't consider the vertical exhaust to be an improvement.
New axles were required to accommodate the new seals. The Ford part number on the box shown at left is on the top line: B8A-9431-A. Below are the serial number ranges and some of the features of the tractors in that range. All N-Series Tractor Serial Numbers were hand-stamped on the engine block, up high, on the left side above the starter. However, pumps have been changed over the years, so this date should only be considered to confirm other dating clues. The earliest 9N's had cast aluminum hoods that are very rare and collectable today.
The confusion starts with the very first year the 9N was built. The serial number is located on the left hand side of the engine block, just below the head. I'm a bit skeptical of one that high. While it was possible to use a wheel from a 1964 Thunderbird on the rear of a 1965 Thunderbird, that wheel would not fit on the front wheels, and as such was unacceptable for use as a spare tire. When the part is released as a service part, the service part number assigned to the part is likely to initially be the same as the engineering part number. It's also not unheard of to find N tractors with an engine serial number that begins with A253-xx or a similar variant. Our website is not just an online store.
