Morning Folks,
Just a couple of thought bubbles.
Since 1990, Australia has had a standard for the design of ride on mowers - AS3792.1 (minor amendment in 1991). This Standard addresses, among other things, requirements for cutter deck safety, stability and braking.
It requires minimum stability to 30 degrees fore and aft, and 20 degrees laterally and also requires both a park brake and minimum standards for a service brake.
I'm assuming all Australian built machines since this time have met this standard. Perhaps it's not a mandatory standard but it would be a foolish manufacturer (from a liability perspective) who would not be be able to demonstrate these minimums.
Also, I'm guessing that most, if not all, 1st world countries have minimum standards for ride ons and that the requirements are fairly similar and for reasons of liability importers would be able to demonstrate that their machines and the standards they are built to emulate those of this country.
Cheers,
