New rider mowers cost more than a used car these days, parts are hardly available after 5 years, but customers keep buying "new" for the feel of it more than the reality of the "throw away" trend they have created.
Push and self-propelled mowers are having catastrophic failures after only one or two seasons.
Product quality has diminished since the old days of the flat head engine and steel body designs.
The final nail in the coffin is adding fuel injection under the pretense of emission standards and fuel economy. Electronics beyond ignition and charging system do not belong in such a regularly harsh environment like lawn care.
We are living in the future where garbage fuels, poorly made parts, and unreliability that just keeps the rich happy with their investment portfolios and the end consumer stuck with junk.
