Didn't realize it was Tuesday, I normally post these on Monday
Well here's pg 2 of the test from jan 30,1957
6. Incoming material is controlled. To within:
( ) a. 2 inches of the shear bar.
( ) b. 6 inches of the knives.
( ) c. 4 inches of the shear bar.
7. Most competitive forage harvesters have:
( ) a. No means for protecting cylinder such as we have.
( ) b. narrow throats that don't need any means of protecting cylinder.
( ) c. Much simpler, more effective system of protecting cylinder then we have.
8. The flywheel type of cutter has a:
( ) a. Variable cutting edge speed, but vary little deflection compared to the AC.
( ) b. constant cutting edge speed, with greater deflection than in the AC.
( ) c. Variable cutting edge speed, with greater deflection than in the AC.
9. One of the "built-in" reasons for more power requirements in a flywheel type is:
( ) a. Knives cut, but don't deliver material- need blower paddles too.
( ) b. knives both cut and throw material.
( ) c. Material comes into machine in a wide, thin stream.
10. The lawn mower type cutter:
( ) a. Uses the same cylinder principle of design as the AC.
( ) b. is very similar to the flywheel type.
( ) c. is completely different in every way from either of the other two types.
11. One of the main disadvantages of the lawn mower type cutter is:
( ) a. The fact that it is so heavily built.
( ) b. The fact that it needs a blower or conveyor with it to deliver material.
( ) c. Knives can't be sharpened in the machine.
12. The AC chopper cylinder:
( ) a. Lightweight for easy pulling.
( ) b. small in diameter, heavily built, with spiraled knives.
( ) c. 3- foot wide, big diameter and has a high deflection.
Hear you go enjoy
