I just got one of these used for $300. It needed Belts and a battery +$130.
Starts fine and the engine seems to be running good.
but ---
It creeps along very slowly, then suddenly lurches forward over and over again.
Withthe PTO off and just driving on a level asphalt road, pedal all the way down
the mowewr will pick up some speed but then slow to a stop until Bang a metal hitting metal sound
then it will lurch forward and drive normally for a few feet before slowing again.
I doubt it is the belts, since the sound seems to come from the transmission, so I suspect that.
I have the operators manual with the parts diagram but Hesitate tearing apart the transmission
when it could be the brake or something else. I can't really get a feel for the theory of operation from the diagram alone. I also read in the thread above that adjusting the linkages help- any ideas what to check? how to adjust the linkages or worst case what parts in the transmission could be the culprits.
Thanks for any help.
Mike
