I have 11 pre 1980 versions of the little beasties now.
More fun than a barrel of monkeys once working, but hard to use for actual transport in my suburban Los Angeles environ, as all but the neighborhood streets typically come with a 45 mph speed limit, which is just about exactly double their production legislated top speed.
For Christmas I just bought a skip dozer that I encountered whilst walking in a nearby wood 7 years ago.
It had been sitting sunk into the dirt for 12 years without running
I took a chance and bought it for $1000.
Now I have it well running, but still on site, as I haven't been able to break the bead of the 14.9" x 24" flat rear tire yet. This despite putting the full downward pressure of the bucket on the bead, whilst standing atop the horizontally placed wheel/ tire, and administering fully hard swung blows with a 12 lb sledge hammer upon an adze placed at just the right angle twixt the bead and rim.
Next will have to be a trailer born ride to an agricultural / industrial tire shop where they presumedly have some more proficient technology and experience needed to accomplish the Herculean task.
The plow in front, and drag box in back are perfectly suited for allowing me to create some sort of interesting roadway on my newly obtained 3.6 acre lot. Presuming that I learn how to control the machine and make a dirt road, alas, I will have a place to enjoy my test rides with less fear.
P.S. I don't smoke or drink that much beer. This is the kind of job that where non micro orientated helpers can be most appreciated.
