520H 1996 Onan 220 Governor Adjustments RPM
Gadget posted a topic in EnginesThis is a question in two parts Part 1: What is the recommended RPM for operation of the Onan 220? I know that sounds obvious, to many of you but not to me, and I know it depends upon what attachment you are using and what the load is. Here's where I'm at: Throttle all the way up, I max out at about 3200, then it creeps back to around 3000. almost all I do is mow with th 48" deck, Seems that a higher RPM will give a cleaner cut, when I really push the throttle up, and hold it in position I can get it to about 3500 but I have to keep my hand on it or it will creep back. I fiddled a little with the linkage and then I stopped thinking that the governor needed to be properly set. Part 2: I am not lazy, I did a search on this and couldn't get the answer, If it is already posted somewhere, just say so. One of the things I like about you guys is that you don't pounce on us for asking questions that may have been answered somewhere else already. I belong to an auto motive form and those guys are ruthless, you are not. Back to the question. I can find and have downloaded just about every manual I can find that applies to this machine and I cannot a "Repair" manual for the tractor. I can find service manuals but nothing that is step by step repair like a shop manual would. I am missing something? Part 3: Lacking anything else, can someone at least tell me if I need to make adjustments to the governor and if so tell me how I can find out how to do it? I thought I had CLEANED and degunked everything until I started reading more closely the posts and photos about chaff building up behind the flywheel and blocking airflow to the rear cylinder. Even though I could do a visual with a flashlight and it looked clean, I though I better check anyway. I took the "tin" off and everything was surprisingly clean so I decided not to push my luck and bolted it back together. At least now I know its moving air as it should. Thanks for the info on that. I have attacked a picture or two of that process and a (not so good) view of the throttle governor linkages. Thanks!
2000 RPM Cross Brand Compatibility Mowers
jmack posted a topic in Implements and AttachmentsI became a little curious when researching the PTO RPMs of older Wheel Horse, John Deere and Cub Cadets. I read that "Woods Equipment" fabricated the Wheel Horse D finishing mowers back in the 70's and maybe the 80's and these mowers were belt driven, and I'm guessing had large pulley that appeared to reduce the 2000 RPM to a more manageable/safe speed. Mike Duwe from other forum (weekendfreedommachines.com) discovered that John Deere and Cub Cadet also had REAR PTOs with 2000 RPMs similar to the D Series Wheel Horses. Because of this, is it possible the John Deere 260 Finishing Mower and the Cub Cadet L42 Model 349 would fit the D Series Wheel Horse? I'm not sure of the rotation direction, spline and diameter differences between Wheel Horse and John Deere are, but this would make finding a D Series finishing mower slightly easier.
