A lot of what is in the web is out of date as things move very quickly
It has always been a problem that nothing has a creation date so you have no idea if it is current or 20 years old unless there is a date in the text.
Briggs are now bankrupt for instance. They are considering flogging off all of their wholegoods divisions which means in a few years all Briggs branded products will be made in either China or India or the brand will cease to exist all together just like Tecumseh .
Add to that lots of what is on the web is plain wrong
Then there is the distinction between "who makes" & "Who owns ", not the same thing and oft conflaited
And AYP is owned by Husqvarna but the only BRAND they own are Husqvarna & Jonsored all of the others are owned by private companies.
Then you get confusing things like Husqvarna owns the Poulan, & McCulloch chain saw brands, but not the riding mower brands .
When a company goes down the drain, the liquidators are bound to do whatever they can to recoup the most money for the creditors
So when a company like McCulloch fails they can sell the entire name McCulloch or sell each part individually so while you see McCulloch, leaf blowers , chain saws , walk behind mowers & ride on mowers, each is owned by a different group and that also happens internationally as the McCulloch brand name in Australia is not owned by Husqvarna but by a Hong Kong company who used to make McCulloch & some Ryobi products sold in the Asia -Pacific region
The Craftsman brand riding mowers is owned by RGS in Aust & NZ but not anywhere else in the world but RGS do not own any other Craftsman branded product including the push mowers .
The world of big business is very confusing and post Corona it will be vastly different.
