Check out Bob Duescher's nice 700 that's been in the family since new... and his family's tradition... Bob says:
As a child we had a tractor just like this Model 700 Wonderboy. In 1971 we replaced it with a 3212 still use it for cutting the grass at my new place, which is 1 acre. I still use the mower deck off the original 1959 Wonderboy. This tractor came from my wife's uncle, who bought it in 60 and used it until the early 70's. I worked on trying to buy it since the late 70's, and finally got it from him last year. And now it looks like new and runs as well.
This is a picture of the first 700 we had -- it led a hard life, but I missed it when it left in 1971.
This is the 3212 tractor we got to replace the 700. It took care of 1 acre of lawn and 1/2 acre of garden.
