1/2 inch is just a little much. I don't agree with your last statement about your cheapskate purchaser comment at all. Not everybody can afford to spend 5 to 10 thousand dollars for a mower like you can. other then that I agree.
Well if you look at my profile you would notice that all of my mowers come from the 60's & 70's when ride on mowers were a luxury item so there was a good profit in making them and they were made to last for a very long time and to be fully serviceable.
So no I can not affod a $ 10,000 mower and seriously doubt I would even look at one.
It is one of the sad features of the modern Western population that there is an expectation , in fact a demand that every year everything we want has to become cheaper, in real terms at least and oft in actual $ price.
we want MORE MORE MORE and expect to pay LESS LESS LESS.
Thus in order to sell anything makers have to find ways to reduce the cost of manufacture.
So if two mowers look similar we buy the cheapest because most can not recognise what constitutes a quality piece of equipment.
Thus we get a whole generation of mowers with garbage engines ( Courages & Inteks ) and things that make a mower servicable , like adjustable linkages vanish, in fact tie rod ends have just about vanished.
professional liars ( advertisers ) convince the technically ignorant that "Quality" is all in the brand name and has very little to do with the item ( mower, car, Hi-fi even ice cream or chocolate bars ).
The mug purchaser buys what they are told to, so the makers of genuine quality items have to drop their prices to match the "advertised quality item " and the only way to do it is to downgrade their quality to match the poor value machines Joe Public is buying by the ton.
dads first powered push mower cost him 35 ginneas ( 35 pound +35 shillings +35 pence ) It is pushing 50 years old and still working perfectly. My sister has it ans I do a service most years on Boxing Day when I have lunch with her.
The purchase price was around 2 months wages.
How many push mowers out there cost 2 months wages ?
Nearly any residential tractor style mower will cost less that 1 month's wages
1/2 the commercial ZTR's cost less than 2 months wages.
So have a think about it.
Think about all of the great mowers that you have used over the past 20 years.
The ones that were a delight to use, that were cheap & easy to service ( OK they actually needed more service ) and seemed to go forever and chances are the comany that made them went to the wall.
The brand name may still be around but the mowers are not.
