I posted a thread a while back about repairing Grasshopper G2 hydraulic pumps. It doesnt sound like the rebuild on the G2 pumps is cost effective. I found a guy on Craigslist selling two Grasshopper pumps and wheel motors for a reasonable price. He doesnt have the model number of the mower that they came off of. I know that they arent exact matches to the pumps/wheel motors I have but I was thinking that if the bolt patterns were the same then I may be able to replace the entire unit (pump/motor combo). Any thoughts or comments regarding if these parts can be interchangable?
