Hi Paulie,
Have a good look through the following thread as the specimen mower is of the worst case scenario.
We here on ODK call it the "Mr.Jones Gusset repair method".
https://www.outdoorking-forum.com.au/forum/ubbthreads.php?ubb=showflat&Number=64696If you have these skills as you suggest at your disposal then nothing should be too much of a problem for you and you won't have to look for another mower.
In saying that, many people will have to pay for these services and then with all spare parts and sundries required on top it then becomes an over capitalised project that rapidly has interest lost in it, therefore it then ends up in the for sale listings, if you get where I'm coming from.

Cheers,
BB.
