Hi Vm,
If you buy a new one its worth more than the mower.
Sometimes I just adapt one from another mower .
The Face Book mower groups may have someone with parts ,I'm not sure if anyone here collects these mowers any more..
From time to time I do see second hand ones on eBay but at about $9. postage it would be $20.most likely including postage.
Cheers
Max.
