The old Deere 20 series combines have a back window in the cab. There is also a window in the grain tank. Once the window in the grain tank completely covered the bin is full. This is assuming they don't have grain tank extensions.
Since the 9400-9600 combines they've had full sensors that sound an alarm when full.
Funny story. I went through a combine inspection on a 70 series jd combine and talking with the customer I mentioned the grain tank full sensors didn't work.

It'd be nice to get them working again because it doesn't take long to have corn running on the top of the cab and going all over the place. I thought about drilling a small hole in the extension so I could hear a small trickle of corn on top of the cab shortly before it comes running over the top."
As you can probably imagine, cosmetics don't really matter to that operation.

The year was about 1967 and my father found a good used Ford 601 tractor to use on the farm instead of "Bob", our old mule. Now my grandfather had had this mule since the mid 40's and he was getting some age on him. S
