INFORMATION ON “55 SERIES” TRACTORS

  

WHY GET A “55 SERIES” TRACTOR INSTEAD OF A “50 SERIES”

 

            The “50 series” tractors came out  in 1983 and then by 1989 the“55 series” were introduced and they had many important updates and improvements to make a better tractor. This was also the last series built before all the electronics.

            The “55 series” where only made four 4 years, (1989 - 1992) and are not much older then the “50 series”. One of the differences when you look at these tractors is the hours. If you research the “55 series” you will find a lot of them show 9,000 - 11,000 hours and when you compare the hours from this tractor to a “50 series” the hours are much higher. The reason for this is the newer electronic tachometer puts approximately 30% more hours on then the old mechanical tachometer that is used on the “20-50 series”. For example one with 9,000 hours on it that has had regular maintenance and has been looked after is more like a 6,000-6500 hour tractor.

            We have been around the “55 series” models for a long time. We use them on our farm as well as work on them and the better you become accustomed to these tractors you learn the hours on them are not near as accurate as the older ones.

            The credibility and value of this series is becoming more and more apparent as there is becoming a bigger market on this series and people are also starting to collect them.
