Old, But Not Completely Obsolete

WINCO has been in business since 1927, starting with wind turbines to power a family farm’s radio batteries. As we have grown through the years, generators have been created and became obsolete while new generators were being designed.

One of the great perks of owning a WINCO generator is the longevity of support. We have 50+ year old units still out there; powering homes, businesses, farms, etc. The key to a long life is simple; conduct routine maintenance and replace parts as needed.


With over 20 years of experience at WINCO, our parts department is a wealth of knowledge of our generators, new and old. You would be amazed at all the part numbers they can rattle off from the top of their head.

Not too long ago, a customer needed AC brushes for his obsolete Winpower GE6W4 restoration project. We had the parts he needed, along with rectifier diagrams, and he was able to finish the project.

Now, we must state that we can’t get every part from the past. As years go on, some suppliers went out of business. But, we will do our best to help you.

Our parts department has a library of all parts list of generators built.


Beyond getting parts, we also can help with technically questions on older models as well. Our technical support team is knowledgeable not about our generators, but also has an education in AC & DC electrical theory as well as working experience with electric motors and controls.

Being a company that likes to hang on to things, really benefits our customers. You can find manuals and other product support documents on our website by searching your model.

This 45 year-old unit came out of Dow Chemical in Midland, MI. Our technical support team was able to help with this customers questions.

WINCO’s Lil’ Dog is Getting a New Engine

No, the Lil’ Dog isn’t on the dangerous breed list, but it will lose its CARB certification. As engine manufacturers are going through tough times, tough decisions need to be made. Because of these new changes, the W3000H will be equipped with a new engine next year.

This does not change the dynamics of the small, hand-held, portable generator that you all know and love. It is still light-weight, coupled with a Mecc Alte industrial gen end, industrial Honda engine, and able to power those lil’ jobs.

Our portable generators are one of our most popular products. With a long-lasting, durable design, these generators have proven themselves in the roofing industry for decades. But that is not all that they can be used for.

The Big Dog industrial portables will work for many applications; including being apart of the spray foam industry. If the power goes out you can also use these as back-up power for necessary appliances.

With design updates and larger output, the W10000VE has been evolving into one of our best selling portable. We engineered the W10000VE with a Briggs & Stratton Vanguard engine, coupled with an industrial Mecc Alte gen end. The robust receptacle package is GFCI protected. It includes our YourGen meter, which allows you to keep tabs on engine RPMs, load balancing, frequency, voltage, operating hours, and alert when oil changes are needed.

If you are looking for a portable generator that you can depend on, don’t pass up on the W10000VE.

Prime Power in Gasoline

We have always built great commercial grade portable generators fueled by gasoline. Currently our air-cooled models can supply up to 19kw in both single and three phase voltages. We regularly get asked for more power and engines that last longer and run 1800 rpm.

When we say we listen, we mean it. We are excited to add to our liquid-cooled family of generators a gasoline, prime-power certified option. Our new PPG28 provides 30% more power than our biggest air-cooled generators. Operating at 1800 RPM it is a great investment for for commercial users that need a serious generator to keep their business running. Check out the table below for reasons you should consider the new PPG28 for your business.
