windshield

My IH-7500 windshield has thousands of fine scratches on it. It almost looks “hazy”. Am I on the right track that it might need to be polished? Anyone do this and can impart some constructive or helpful suggestions on what product/technique to use?

My new Kubota M6 front windshield washer drains back into the reservoir. It takes over 30 seconds to get water to the windshield. Dealer tech says they all do it. I have never had a tractor do it. If this is standard I can put a valve in the line but I cannot expect this happens to everyone...

Does anyone have a source for a cheaper cap for a kioti windshield washer fluid reservoir cap. Mine didn’t fit when I bought the tractor and now it’s completely missing. The only one on line was around $18 for something that shouldn’t be more than $5.

Looking for source for Kubota KX040 (lower) Windshield replacements. Would prefer polycarbonate but understand that is in short supply. Will be glad to use tempered glass. I can find them for the KX080, but thus far not for the 040. Do these cabs happen to be the same size?
