Zuma, I certainly liked the tractors. Really don't remember the vacuum cleaner much.
Ed, I have no idea what it's worth dollars wise. I heard a few of the collectors around here saying that the old tractors really went down. The men that used them are thinning in numbers. Many of the next generation have no interest. I heard the 10 and 20 series are drawing more attention. Still more of those fellas around and those tractors can still be very handy, especially if you have a loader for them.
Jerry, yes very distinctive sound all it's own.
Pappy, the first tractor I ever bought was a used 1968 John Deere 4020 with a year round cab. The cab got taken off right away. Those things were torture to be in. My brother and I bought it together in 1984 and paid the fella we got it from more than he paid for it brand new. Pretty sure it's worth more than we paid for it now but a dollar isn't worth near what it was then.
Badger, do you know what model it is? John Deere is still pretty good for getting parts. Might or might not be worth fixing. Maybe you can at least get it parked in a good hunting spot. Use it for a brush blind.
