I take it that you simply disabled the operator presence control? (The brake handle that you have to hold in order for the engine to run) That system also incorporates the ignition kill... what are you doing for a kill switch, especially in case of emergency stops?

If we accept that: MBG(+)FGSF(=)HBG(F1)
And we surmise that: BG(>)HBG(F1) while GSF(<)HBG(F1)
Would it hold true that: HBG(F1)(+)AM500(x)q.d.(=)1.5lbGRWT?
PB answer: It depends.
