anyone out there have an explanation for the four windshield wipers??? Tim Verande photos shows them too on Eng 64.

there was a 4 wiper option on the century series rigs. it gave better clearing capability, due to the curved windshield. Without it, a pretty large area of the windshield were not touched by the wipers.

Except of course, for the non-curved screen on the code 3 model
