John Deere Roll-O-Matic Predecessor?

In regard to a question from Richard Hanson (Farm Collector, March 2009, page 6) about offset wheels on a 1938 John Deere Model A: This is what became the Roll-O-Matic on John Deere narrow front tractors. In north Jersey we have lots of rocks and groundhog holes. This type of front end helps smooth out the travel – the straight type can be rough and often would break off.

I enjoy the magazine.
