| We put these on our spreader, one on each shaft. it does require some redneck engineering though.
The little round magnet we JB weld to the shaft, and made metal brackets to attach the sensor. the wire that comes with them isnt that long, so we got some wire at an auto parts store to run from the tractor to the back. We made a bracket to attach the 2 readouts to our monitor bracket in the cab. We solderd all the wires together, rather than crimp them. Its held up better than I expected in the fert enviroment. We had to replace the magnet once when it came off. We keep an extra kit on hand since they are cheap in case we need to fix something
We buy ours off Amazon, they are similar to these
