 Topic: 20 years difference, but worlds apart
Posted: 15 Jan 2012 at 8:00am |
Our 170 Diesel in the background. Delivered in April of 74. Was a demonstrator at the local AC dealership during the 73 year had 150hrs on it when we bought it, it's a 72 model. Our 5670 in the foreground. Delivered spring of 94. Was a demonstrator as well at the same dealership had around a 100 hrs on it. They have both been very reliable in a mechanical sense, but as far as ergonomics, better hydraulics, noise, and lugging ability the 170 is the winner hands down. I know the 170 design was more of a row crop tractor plateform while the 5670 was utility, but the 170 is just a more user friendly design.

Dr. Allis, I always wondered about the "float position" and why more tractors of other brands didn't incorporate it especially on their utility tractors. So much more convenient with brush hog and grader blade.

It is clear to me any tractor that doesn't have "float" position in the remote valves was designed by an engineer who never grew up on a farm with a D17 series 4 tractor.

Many brands have a float on the three point. Can't be any other with only single acting 3 point cylinder(s) set for lifting.Which takes care of brush hog and blade float.

good point Gerald, now that you mention that ...the "detent" or "hold" position on the AC hydraulics is probably what I should have noted as a big benefit when working with the blade or bush hog

Here is my 20 year spread. The 1957 WD45 had all the latest features for the model and at the time was THE work horse on many farms. 20 years later the 7060 was an entry in the horsepower race and brought many farms to the modern era of operator comfort and convenience.
