PROCEDE POUR MODIFIER LE NOMBRE DES RAPPORTS DE VITESSES DANS UNE TRANSMISSION

摘要

A method is disclosed for changing the number of speed ratios within a transmission for a frameless tractor. A transmission is provided which includes a housing with an inwardly extending annular flange with a first change gear mechanism being mounted within the housing to one side of the annular flange and an initial second change gear mechanism being removably mounted on the inwardly extending annular flange, the initial change gear mechanism includes a forward/reverse change gear mechanism. A further second change gear mechanism is provided which includes a forward/ reverse change gear mechanism and a number of speed ratios in one direction which are different than the initial change gear mechanism. The initial second change gear mechanism is removed from within the housing and a the further second change gear mechanism is installed within the housing.
