I know that this is an old subject that has been discussed in the past. I bought myself a Norlett Beaver Powerspade off eBay for £50 a few weeks ago as spares or repair. A new spark plug was all it needed (plus a few washers, oil, air filter and I treated it to a new exhaust). It is magic! With a smaller bolt and using only one tine, it is also the perfect weeding tool in our large garden (and of course it has done the veg patch!).
My question is regarding the gearbox. It would seem to be totally sealed, there are nuts and bolts but there are welds that would prevent the box being opened up easily....
How do I service the gearbox or at the very least, see if there is oil in it?
Any advice gratefully received...
