ABOUT US Hello, my name is Brian Wang and I am the owner of Portland Implement in Cashton, WI. I started Portland Implement in 1979 by purchasing an existing Allis Chalmers dealership that had been in business for 20 years. We have sold and serviced A.C. equipment ever since that time. Our business has grown alot since then thanks to our many loyal customers. So if you are not a previous customer of ours, stop in or contact us and take a look at the broad range of products we offer. I'm sure you will be impressed by the quality and value of these fine products.
