Hello, I'm new. I have an Atco Royale B24 Professional mower, 1995 from the plate on the side with a 5hp B&S engine. It has the trailer and I look very happy mowing the garden trying to learn to get triple wide stripes without too many random U turns because I've got out of sync with my directions. Surprisingly two large glasses of wine and one beer on the mower and I seem less prone to extra laps around the outside to make sure the stripes are good.
However - the sprag clutch which disengages the drive to the blade appears worn, and now when I try and drive the blades hardly turn and I get a fast click-click as the sprag seems to bounce over the dogs. Being 110kg its hard to lift onto a proper roller and review in the garage so I am assuming a little here.
When not drunkenly mowing on my private property I race F3 cars (sober). I also build the engines and gearboxes and so I think I am mechanically sound. I attach a sprag clutch photo - the dogs are rounded and worn.
Where would I find a replacement to the two parts? Obviously its been case hardened, so to grind new dogs wont last as I'll wear through what is probably fairly thin chemical hardening. By taking the top hat washer that holds the retaining spring in place and putting it on backwards I can (probably for the short term) lock the clutch up but, its not a fix is it?
