So bought a grain tank sensor off a 9500 for our 7720 to install, need an indicator. I was going to wire sensor to key, run wire back behind the dash, put a light and be done. Only one sensor no backup, not much early warning. Would i regret using a sensor like this if i put it on a switch to be shut off? https://www.amazon.com/TmallTech-Flash-Alarm-Indicator-Buzzer/dp/B01...https://youtu.be/fdz6m0O3zpk Thinking it would be close enough to operator he would hear it right away and not get distracted and not see light until it's too late. Was just planning to setup sensor so would have time to come to a stop and let machine empty out not much extra room. I've been doing this all by manually turning around and looking in bin extension so thinking i can do this pretty easy i know right where i need to mount it. Thanks in advance.

My only thought would be to have a switch to turn it off when the operator is waiting on the cart to come unload. That would get really annoying really fast I would think, granted I'm not sure how loud 80dB is. Otherwise I think that light/buzzer looks like a nice unit.

All newer machines I've been in (JD and Lex) the buzzer goes off along with a visual display, then the buzzer stops after a few seconds and the display stays until you clear it or unload past the sensor.

I had a bin alert on a 1680 combine. It had a separate switchboard with a light, switch, and buzzer. I believe it was wired similar to a 3 way light switch. When the bin was full, light and buzzer came on. Flip switch, light stayed on but buzzer quit. Emptying the bin, light would shut off but buzzer would kick on until you flipped switch to reset it. I kept it, probably should put it on my 2188. It worked a lot better than the stock one on the 2188. The stock one doesn't work so well mounted on the bin extension.

I agree with emtbed79. On my 9660 I had 2 cab cams mounted on the top back of the grain tank. One facing back, and the other facing forward. The one facing forward worked "double duty". Was GREAT for watching the grain come up in the tank. AND, also worked great for road transport "low wires or trees". When approaching a low wire, I would slow way down, and with the camera, I was able to see if I had clearance. A LOT BETTER than having to step out on the step to check. Now, my S670 has a folding hopper, and grain tank sensors.

Another vote for cab cam. Works great for seeing when it is actually full not relying on a buzzer. I'm thinking of unhooking my 3/4 full buzzer, every time it goes off I think something else is wrong. One on the back also makes it much safer backing up. One of those "once you have, you'll never do without type of thing"

My 9770 has the alert system from Deere, but I like a little prior warning. Several years ago I saw where a neighbor had mounted an automotive rear view mirror on the right hand rail.
I found a cheap rear view mirror and mounted it to the hand rail pipe with some hose clamps. It is aimed at the window in the grain tank extension. This allows me to directly see the level in the extension once it gets into the window area.

The desert of MN.
Our Challenger has a factory mirror just to look at the window in the grain bin extension. It also has the 2 alarm sensors. One at 70% and one for 95%. The round mirror works very well day or night because there is a light in the tank. So when the window goes dark you are getting very close to full. Simple enough and no electrical things to go wrong, just clean the mirror every few days.
