I am surprised at Mr. Rogers: I am not very flexible but had no trouble in locating the jack on my Triumph Herald for a rear wheel change. No need to lie on one’s belly. And what jack is he using anyway? The Herald normally comes with a mechanical (not hydraulic) jack which on my two Heralds was perfectly reliable. But I did complain about the lack of fuses when all the wiring failed simultaneously.
