as can dirt humidity and vibration on any system. If they are designed properly in the first place I don't see that it would be a problem. All the electronics could be potted once the heat problems are worked out. They should last indefinitely then. I think the problem with electric vehicles is that because they are new and different they never get past the prototype stage before the press slams them for breaking down. If it was a conventional vehicle, I am thinking of the merc A series, with a fundamental design flaw like falling over going round corners, it is whisked off the market and redesigned. The problem with the electric tractor is apparent in the last set of figures on 20 year costs. If you are selling tractors you can make 3.8 times more money out of conventional tractors as well as all the spare parts you can sell as well. Sad but true money makes the world go round. If the tractor manufacturers were made to pay for the pollution there products caused... The economics are never going to work out from a manufacturers point of view unless total pollution costs are borne by them. Not in my lifetime. Opps another long ramble...sorry...
