Sounds like this mower cuts better in a dry area like Queensland Speedy, looks like it's missing the self tapper in the side to stop the handle flexing.
Too many fussy buyers in my area ,I've seen a few sell for $20. on eBay ,If I wanted $70. I'd have to use a different base with a plastic catcher ,people here don't like the bag catchers.
Another problem I had, was the cast iron boss on the crank would be broken when people hit a rock with the bar blade.
Lots of cheap mowers for sale these days. Hopefully someone will want the Braum-AG 660SX mower soon Speedy.
