Proof-Meter was the Ford Tractor trade name for a tachometer. Magnetic pulley is a misnomer for magneto pulley. Proof-Meters were heavily promoted and extremely popular on release. Ford Tractor immediately issued an update kit and even compensated distributors and/or dealers for installation. Ferguson was the distributor in Michigan and they installed the kits on all non-PM tractors they had prior to shipping. Lots of errors in Ford Tractor literature. Too much corporate bureaucracy interference and delay being the main cause.
