The following tables have been given so that they can help you decide what you need. We are proud of being a distributor for Katolight as we believe they are a superior product. One of the things that one notices when comparing Katolight with other PTO generators is the Momentary surge watts. What is impressive about Katolight is that it is three times the continuous watts (or continuous running). When comparing other brands notice the difference between continuous running and momentary surge watts. A generator can only maintain that surge for a very short time, often just to get the things "up and running" from no load. The other thing to consider and watch is the Horse power of your tractor. You should know that before purchasing any PTO generator, your tractor must be able to carry the load. Finally, notice the weight. Lighter is not better when it comes to generators. More weight means more copper and heavy duty materials. Weight should be something that enters the equation when choosing a generator. We would love to walk you through all this. Please give us a call.
