Once during mowing, my JD 755 overheated and quit running. After my heart attack and cool down I noticed the outside grill was clogged with chaft (?) from mowing the bone dry grass. Yes, I do clean it regulary and keep the radiator cleaned but.... Anyway, someone today told me a "johnson switch" most likely shut down my engine before it seized and was a typical feature for JD products. I plan on getting a real temp gauge (any suggestions?) to augment the idiot light, but I'm curious about the "johnson switch". Does such a thing exist? Is it standard on a JD 755? Thanks for any info.

Jeff,

Interesting question, I assume your Johnson switch is only the manufacturer, Johnson Controls and that the switch in a simple RTD or thermoswitch. Do not own this tractor but would assume if you have any wiring charts for it that they would indicate the switch and cut-off scheme. Any JD fans out there with better info?

Jerri ....
