I remember as an apprentice at a Fordson dealership in the sixties being given the job of mixing the calcium chloride flakes with water then hand pumping the solution into the rear wheels of Fordson Majors just below the centre line to stop surging when traveling in top gear. Using wheel weights or a land wheel strake was the other option, but with the introduction of diff. lock and weight transfer hydraulics on the Super Major, thankfully the practice ended, Brian.
