Jonny, the grinding head slides forward to tension the belts. Thanks!
Edit: I did have to replace the engine. In my mind I thought running synthetic oil will make the engine work better. It didn't. I also had oil blowing out of the nreather, seems there is a return hole in the breather plate that drained oil back into the crank.case. I installed it upside down and it constantly blew oil out the breather.
I think I’m going to have a talk with my pro welder friend, and see about shamelessly stealing your design
I’ve been thinking about it for a while.
I’d like to use this little wheel, it’s called Blueshark, made for the little Toro 13hp.
I used to own one of these bastards, the Merry Mac. Nothing merry about it.
It was pretty awful. Made some bucks, and simple to maintain and repair, but once the teeth lost their edge just a little bit it was over until replaced or resharpened.
Lol true, I'm in the bigger is more better thinking with stump grinders, and the you can hire someone else for stumps mindset. But still man, he built it!! And he makes money with it. Not as fast or comfortable, but it's still profit. Maybe I've just done a bunch of painful stuff for money over the years
I’d like to try totally copying the design of the Alpine Magnum and have one built.
I’ve never seen one up close, but looks pretty simple, and aside from the cost of the power head should be a fraction of what they sell for. Hardest part might be fitting the belt drive pulley to the power head, and if I use a demolition/ concrete saw, that part is already done I think.
Advertised as 4800 rpms on the cutter head of the AM, while I’ve read the Vermeer sc252 is around 1100.
Not sure how accurate either of those are, but makes sense that you’ll see much faster speed coming from a biggish 2 stroke.
