heres the skinny on what i know bout the ridley they have a machine shop that makes a couple of neet parts and yes i own 1 how do u say i bought it from a freind who let it fall off his pickup gate. so now it has a broken clutch cover i decided to buy a new cover and mount it to my frame only one problem ridley will not sell me a new part. so i decide to take it apart and see what the difference is notta thing just some pretty mounts and a fancy clutch cover. carb,clutch,piston,jug,exaust everything matches my little china made motor!! so mr vender take your i think their great and stick it i see someone who is buying cheap putting their name on it calling it better when its not!!! its like buying a chevy adding a caddy emblem the selling it for 20,000 more then its worth. yes there are folks who will buy them because of the name but they have more money then brains how would someone like it if they bent the blade on their mower come to me for a new one and i tell them they have to buy a whole new mower i dont sell just blades thats a butch of **** a part is a part if you need one you should be able to buy it from who has it. oh and buy the way an argo is a 6 or 8 wheel machine that will float it is made in canada an all tearan vehicle and yes it has a vanguard that says vanguard not argo on it . also if i dont like the motor i can replace it with another vanguard i dont have to buy a whole machine.
