How well did the homemade ac work? I have an old 4020 with a cab and it never had ac. It would be nice to have a cheap way to cool or down some
I works great. Sure it does depend on the weather temperature, but there is a clear cooler feeling difference inside the cab. It takes a good insulated cooler to get the job done.
Did it end up working while doing hay
There is an update available for the ac pump on that tractor , r6 to sanden style Either from deere or local sourcing . Did one on a 4640 . Would recommended a suction filter adiddion.
