Ok. I just got this Cub Cadet commercial 1548 and all of a sudden going uphill it just does not want to go. It's a belt drive and I can see that the transmission has totally stopped turning. Also on the hour meter it keeps flashing "LUBE". Are the peerless transmissions in need of a fluid check. I called my dealer and he said that they are self contained. Furthermore, on the straightaway, this thing moves like a beast, its just on slight inclines that this happens. The same lawn a month ago it was tackling without a grunt, but now I am doing the grunting pushing it up the hill. Does the tranny need to be regreased or should I be checking something else???
