Parker Soil Pulverizer

Bring Back To Life the John P. Parker Pulverizer

from issue:

Meanwhile, my senior year was approaching fast, and all of us students began to contemplate what our final project would be with a bit of urgency. Our capstone project tasks us with identifying a need for a product or solution, bringing that product through the design phase, then building that product and displaying at the Technical Exposition. So I had the harebrained idea to embark on recreating not only a scale model of Parker’s Pulverizer, but to also recreate the real thing in full-scale, complete with fresh new wheel castings.

from issue:

Place wheels on axle. If wheels do not fill axle completely to the turned shoulder, fill up the space with axle rings. See that axle and end bearings are well greased; then place brackets on axle and secure with axle washers and cotters, using that notch in the washer which allows the least possible end-play of wheels on axle. Bend ends of cotters around washers so they will not catch on the inside of dust caps.
