Great question. You may want to just give us a call with all your questions, but in general terms: the MH8500 is loaded up with all of our heavy-duty components, whereas the MH4900 you can buy a little more stripped down or build it up based on needs and budget. For a more detailed explanation, please give us a call at 1-877-828-8323.
Aside from the engine, what are the main differences between the MH4900 and MH8500 ?
