Totally oddball idea I have here, looking for ideas. I have a mx 5100 pulling a 15 ft flex wing finish mower woods. Worksreally good, unless grass gets a week or 2 ahead of me. I need to keep tractor, hst is a must and I don't want to invest boocoos into a mx 6000 for that extra 6 or 8 hp I need for that extra boost occasionally. My idea is to make a 21 hp lawn engine with a clutch drive line to connect to rear deck as an add on, one way clutch etc for those heavy days. Can't quite get the whole picture in my head that won't either have the tractor doing less work and the mod bogging or the tractor doing the work and the mod doing none. It would basically run full rpm with tractor rpm match and load up same time tractor does. Maybe I'm dreaming but I see it in my head. If I can't get it on paper I may just take rear pto shaft out and put a larger engine on rear and just run it independent full time.And ideas or laughs welcomed!
