Yep,
Briggs just screwed over their parts suppliers ( and the tax man ) for $ 900,000 by filing the chapter 11 .
So would any one be surprised if the company that makes the magnetos for the 20 year old mowers says "Stuff you and all of your customers " then dumps all remaining stock on ebay .
Happens every day .
As for the mower, it is only a motor .
So there will be some sort of engineering solution .
A hydro motor is a hydro motor is a hydro motor.
Oil goes in one side & comes out the other
Ho much passes through determines the speed and the direction determines the rotation .
The question is , will the customer wear the cost of the modifications.
Eaton decided domestic mowers were not profitable near 20 years ago.
They offered the tooling & IP to the market but the market called their bluff, so they smashed everything, including all of the service parts.
This was one of the reasons why Bolens went broke .
But I have 4 Duratrac sub compact tractors in my service run & we can always find some one who will take on a hydro work around to keep them running .
The big problem is he franchise rules that the JD dealers have to work under.
SO when head office says they can not be fixed the dealers are left holding the bag of dead kittens.
An independent workshop can look at it, cu the frame, make up a new mounting plate & fit a different motor then work out how to link it to the existing lap bars .
To a lesser degree an non JD dealer could do the same ( but is highly unlikely to ) .
Cold comfort for you but usually the HO will come up with a generous ( and ritefully so ) trade in deal if you push hard enough ( which you should not have to do )
