Bob M said: (quoted from post at 10:46:51 04/22/08) Original intent for the wedge is to lessen caster and thus reduce steering effort - sort of a "poor man's power steering". However this reduced caster makes the steering less self-centering. And if there's any slop in the steering mechanism it'll make a wobbly front end even wobblier when running on a hard surface.
That orientation for wedge installation is what I thought. However, that installation gives more POSITIVE caster - making turning somewhat more difficult, but tracking more true. On an automobile positive caster is when the lower ball joint is further forward of the upper ball joint - or, when the bottom of the king pin is further forward than the top - thus placing the spindle with a forward pitch at the bottom. For example, a "chopper" custom motorcycle has extreme POSITIVE caster, and should give more straight line stability but more difficult steering. Do a web search on Positive Caster.
Placing the narrow end of the wedge at the front of the farmall bolster has the same effect on the lower bolster (bottom more forward than top). That is POSITIVE caster. So, I must conclude that the purpose of the wedge was steering stability, or better tracking.
Anyway, you have answered my question by showing me the "forward" orientation in the photo, and that is what I wanted to confirm. Thanks. mike
