In general the loads and stresses for the blade would be greatest near the pivot point.
The radial load exists as an almost linear decreasing function (assuming a uniform cross section of the blade) where the max load would be near the pivot point, approximately half that load level would be a the mid point, and the load at the tip would be zero.
Note, all these discussions about loading is qualitative in nature, b/c the base assumption for discussion is a nice straight blade with uniform cross section (which makes it easier to picture the general fatigue and loading aspects), the actual stress at any one location could increase or decrease based on any taper in the blade, bends in the blade, and the varying depth of the serrations.
Finally, notice I try and state the load is largest "near" the pivot pin. If this pin is tight (or binds), and there is friction between the blade and the housing disc, that will help transfer some of the load before the pivot pin, which reduces the stress on the pin and in the blade at the pin location.

Today's Featured Article - A Lifetime of Farm Machinery - by Joe Michaels. I am a mechanical engineer by profession, specializing in powerplant work. I worked as a machinist and engine erector, with time spent overseas. I have always had a love for machinery, and an appreciation for farming and farm machinery. I was born and raised in Brooklyn, New York. Not a place one would associate with farms or farm machinery. I credit my parents for instilling a lot of good values, a respect for learning, a knowledge of various skills and a little knowledge of farming in me, amo
