I have a 1110 hydrostatic cub. it does not move. the belt is turning the pump shaft, there is fluid in the resevior, it is as if the pump is completely disconected. Can anyone tell me what i should be doing to trouble shoot the problem? i got this mower "as is" and am just hoping to get lucky and have it be something minor (yeah right!!) I can find no schematic on the pump. don't wanna buy a book at this time. If more information is needed i will provide it. thank you. }
