We have a mostly free market in the USA for tractors and other goods.
Suppliers can charge what prices they wish, to be profitable for their workers, distributors and shareholders.
Consumers have a wide choice between brands and within brands, with considerable variation in prices.
Kubota has around 45% market share in non-ag tractors, so more US consumers are satisfied with Kubota's products and prices than competing brands.
L6060 is a Grand L. The idea that a super-premium tractor should be sold at less than a super-premium price is against everything I learned in Economics 101, fifty years ago.
You can buy a turbo-equipped utilitarian MX for less money and have the same tractor weight and nearly the same horsepower at a much lower price. But not the amenities. ((Consumers have a wide choice between brands and within brands, with different prices.))
Here is Kubota's stock price:
KUBOTA CORP ADR (KUBTY) 08/04/2017:
$93.20 +3.05 (+3.38%) ONE DAY
+6.11% ONE MONTH +14.21% THREE MONTHS +30.19% ONE YEAR
Consider buying Kubota stock as well as a tractor. Maybe buy Kubota stock and forget the tractor.
(I do not own stock in Kubota.)
