Having operated a ~1995 7800 with flat glass and a ~2015 7270 with curved, I know which one I'm picking.
Are automobiles using curved windshields so they have a stranglehold on the replacement windshield market?
Your example doesn't pass my sniff test.
How is a curved window better on a tractor?
In this case, glare and reflections.
It’s also stronger.
It's more aero :)
