Help Bobcat S185 dies, stalls pushing loads I need some help figuring out what to do with my S185 It is a high hour machine and when I push a heavy loads Like a dirt pile the wheels won't even spin in the sand, the motor just Bogs and wants to stall until I back off on the controls. I have had other S185's and they just spin tires all day long with no Hesitation. My question is, do I need the engine rebuilt or do I have other Issues like air or fuel problems, not quite sure where to start. I just got the machine so I don't know the history, but there has been A couple times when the machine wouldn't start and I had to pump the Fuel bulb.
