72" wide blade might be a bit much if the snow gets really deep. I would reconsider a 60"plus blade to save some wear and tear. If your snow is rarely deep then the wider blade might work OK. The 700 engine and transmission has been around for many years not only in Kymco products but also Artic Cat, Suzuki and others. From all the 700's made over the years those two having tranny problems is quite small as I have never heard of any other issues in the 3 yrs I have owned Kymco. You never know how the owner treated his transmission while he was plowing and did he use low only? Never high when plowing! Many kymco dealers sell only scooters, had one in my area...never even knew Kymco sold atv's & utv's, had been a Kymco scooter dealer for more than 5 yrs. My dealer (75 miles away) has never had an issue getting parts, I just call them with the part numbers and a week later I take a drive to pick them up, take the wife along and have lunch....nice trip out into the county. Many people buy a Kymco then want to make it go faster and have more power, it is not designed for that. They are well made sturdy built utility machines, not off road race machines. They will never keep up with a razor or a Wildcat, never designed to do that. I would never go up against a Razor or a ranger in a race but I have certainly pulled out a number of them stuck in mud where I got thru!! Kymco's are just good quality well built work horses for utility work but you can still have some fun with them on the trail when you want to play.
My soft side enclosure serves me well, there is a custom shop that makes hard enclosures for ANY machine but no one I know can afford to have one built, and yes they are heavy! My Eagle Pacific is well made, easy on and off once the initial setup is done. I spent about two days getting everything done correctly on the initial setup as lots of industrial strength Velcro needs to be glued onto the roll cage and body for attaching the enclosure. Once that is done then adding and removing the enclosure only takes a couple hours at best and at 68 I don't work very fast so I am sure a young stud could do it much quicker!! Surprisingly it seals up pretty good, I did find a golf cart propane heater that works great to keep it comfortable inside. Your not gonna plow in your underware, but the heavy snowmobile suit is not needed nor are gloves....hate operating the plow and shifting with gloves on! Also does a great job of keeping the windshield clear of snow and ice buy keeping it warm enough it never freezes on it. I realize my machine is a 450i and your is a 700 but both are good machines and will do most any job you need them to do, just take care of them.
