Meli....     What kind of bolts are these, and can I still get them somewhere?

These are called "Clutch Head Bolts". They were used on the later "letter series" tractors to fasten the grills and sheet metal parts to the tractor, (See parts number 11 and 15 in the illustration below). You can get brand new bolts from Deerely Departed. They come in various lengths. Just click on the bolts to see where you can buy some.

Why did they use bolts like this!!?

For the same reason we use "Phillips Head Screws" in mass production today. It is much easier and faster to install them with a power driver than it would be if they used regular bolts. Guess what?? You can get a driver from Deerely Departed!! This driver is a "socket" that fits your regular 3/8" drive ratchets. Click on the driver to find out how to get one. It will make life MUCH easier!!
