Pros and Cons of corn pickers

Late 60’s early 70’s when I was a lad my father had a couple D17’s the first was a gas with narrow front then he bought a diesel with wide front traded the gas for a 190 put the narrow front on the diesel so he could run the new idea picker. I remember that mounting the picker seemed like a big chore to my young self it did have side shielding for the engine compartment not sure if that came from Allis or new idea with the mounting bundle that would have came with the picker someone older or more experienced can tell. I also remember he’d put some screen wire over the radiator to help with the air sucking smaller corn fodder into the radiator and when it started getting hot he’d shut the key off for just a second and smack it with his hand to clean the debris collected there
The side shielding would keep corn fodder from getting around the exhaust and maybe starting a fire
Everyone in our area always thought that the new idea picker was a better one than other manufacturers
A good friend of mine still has one that his father had sitting in a barn that is mounted on a IH m it doesn’t seem as big as it did when I was a kid but I do remember they were picking machines
After we started the dairy dad quite doing a lot of custom picking for the community and sold the picker or maybe traded it for a new idea one row snapper it wasn’t the machine that mounted one was tho. It was slower and you couldn’t run as fast or it would overrun the wagon conveyor
Just some rambling thoughts and memories from bygone days

Mounted pickers did the job of opening the fields but you got really dirty sitting down in all the dust and husks.  Dad enjoyed picking corn after we got the pull type New Idea and he could sit in the cab with the heater on.
