1. Spike tooth are for soybeans and some beans crops. It is an aggressive cyl. If lap filler bars are used it will shell corn but at a reduced capacity due to shoe loading and more small cob pieces. lap fillers can be left in a spike whereas not in a rasp and will help in all crops. I contend there is only one cyl setting for a spike tooth and that is 3_8 " because that is the average clearence of the side to side measurment of the spikes. Due to this side to side gap it is hard to completely shell some crops. A spike has double the capacity of regular rasp bars in soybeans; 10% more than wide spaced hard surfaced bars. Finally there used to be a spring tooth lower door option for the spike tooth to handle rocks in kidney beans with out major damage and to prevent the door from popping open all the time as in the rasp cyl in same conditions. Just trivia FYI. 2. The metal curtain is for wheat to prevent the lighter grains at hig cyl speed being thrown to far back on the walkers and result in walker loss. At slower cyl speed the throwing motion is like accelerator rolls and the grain needs to be thrown back so as to prevent some of the shifting to the down hill side of the raddle. 3. The walker can be moved forward to lessen the load on the shoe and vice versa. We always set the outside walkers forward and the middle about half way for hillside help. The majority of the grain on level hits the outside of the inside walkers as attested by the wear pattern on the cyl. 4. The large pulley is for corn only and CAN ONlY BE RUN WITH A CORN KIT!!!! Running a chopper without a kit in corn will destroy the walkers and shoe and chopper shields. See your dealer for the kit whic consist of a curtain, walker end plates, and heavy duty z front shield. Small pulley is for all other crops.
