You fellas can tell me if this is where you want to talk about mower mods.
I've been modding all my mowers over the years.
In the late 90's it was Rover 20" "self drives" which were pretty much 1940's technology and full of reliability problems.
Then in the early 00's, I spent a day modding each industry donkey HRU216 Hondas before they even mowed the first lawn. They were gutless, had handle issues, blade issues, filter issues and wouldn't catch grass if it was wet. But they were solid and reliable, so were worth doing all the modifications on to turn them into a proper mower.
My current mowers are the new HRX217 Hondas (which I was importing from the USA years ago, and pushing Honda Australia to do the same).
They don't need as much modding - a snorkle (from a honda powered victa), independant blade clutch and drive levers, auto choke fix, a steel re-enforcement for the mulch ramp, and lower the blades 7mm so they can actually cut the grass without hanging up on the deck. It would be nice to have a better height adjustment system, but if you get your head around the American 4x adjuster system, you can actually control a lot more about how the mower cuts and how the lawn finishes. It just needs to be finer than 8 settings - of which you only use 1 or 2 because everything else is too high for Aussie lawns.
