Version #1 - 1947a |
The lift strings probably tended to slip on the pulley wheels - leading to their demise. |
Another 1947 feature was the use of the spot-welded two piece concave wheel. |
Barely visible in this photo is a protruding tooth on the mixer drum for the drive chain. These are found only on early models. |
The crank handle to turn the mixing drum was held on by a rubber sleeve over the end of the shaft. |
The material chute lift arms were notched for the string. |
Front corner posts were different than those used at the rear - they were not drilled. |
Version #2 - 1947b |
The lifting string for the materials chute was now simply tied to the shaft. |
The concave wheels continued for the remainder of 1947. |
The teeth on the mixing drum were eliminated. |
A crimp on the end of the drum crank shaft replaced the rubber sleeve. |
No notches were present in the ends of the material chute lift arms. |
All four corner posts were now interchangeable, simplifying the assembly line process. |
