Rated 3.6 out of 5 by 29 reviewers.
Rated 1.0 out of 5.0 by Dont Waste your time, effort or money! I have owned a ton of generators, this is the worst one I have ever come across. This unit only lasts about 6hrs before it breaks down, repaired it and it only keeps breaking down. Company does not stand behind its product. Its a very expensive paper weight! Don't buy this headache!! January 26, 2016
Rated 2.0 out of 5.0 by Pro Series 7000 Watt Diesel Generator The generator started giving me trouble from the begining before I even turn it on. First of all one of the tank hoses was cut from the edge so when I was fueling it with diesel it was driping all over the place. I was able to quick fix it and was runing fine for about five days when the air filter holding bracket fell apart the welding did not hold the vibration. If they could manage to weld that part and that hose which has an sharp edge next to it can hold I think it can do its job. Also it does not come with a battery. I think if those problems can get fix this might be a good generator but hard to tell since I was not able to try it for long. September 5, 2012
Rated 5.0 out of 5.0 by This Generator Runs Everyday for our Excavating Business Flawlessly We have owned this for a year and a half. It powers our bulk refueling station which we use to refuel at the end of every day. Whether it is 90 or -10 degrees outside it starts and performs flawlessly day in and day out. We actually plan on purchasing additional units to run more refueling stations. Reading the reviews, this unit may not be what your looking for if you do not intend to use it frequently, but if you plan on running it all the time, this has given us no problem. February 6, 2015
Rated 4.0 out of 5.0 by Good generator,good price... good price for the generator,i use it for my outside lights,power tools.. June 4, 2015
Rated 3.0 out of 5.0 by Good value for price. Bottomline is...you either going to get a good one that last a while, or you will get a lemon. This generator could not produce 7000 watts no matter how hard it tried. Peak wattage is 6000 at the most and 5000 running watts. The description says it outputs 20 amps at 240 which is 4800 watts. And the engine is sort of a mystery, the specification and description of this item are different. One says 409 cc which is a 9 HP engine, and the other says 418 cc. I guess you really have to look at it and inspect it to know what you are paying for. Overall, good quality if you get a good one. June 20, 2011
Rated 5.0 out of 5.0 by Great Value! Excellent operation!! I wanted to take a moment to express our satisfaction with this product and with Buffalo Tools in general. We are a manufacturer of equipment and needed a diesel generator offering on one of our products. We were having issues with finding units small enough to be affordable to our customers. That is when we found the Buffalo 7000 Watt Generator. We reached an agreement with Buffalo to purchase as an OEM and our customers have never been happier. We even replaced some of our older units with lower quality generators with the better and more efficient Buffalo unit. We also use the propane unit. Their customer support and dealer support system is second to none. Working with Tyler was a great deciding factor in choosing to stick with the Buffalo units as he stayed on top of our concerns and really pushed hard for us to get the OEM line so we could offer the warranty to our customers. We Highly recommend Buffalo Tools for your diesel and propane operated generator solution. - Separation By Design, Inc February 9, 2015
Rated 2.0 out of 5.0 by NOT HAPPY Purchased but not used right away, had to find a battery to fit. When it worked it worked great. Within 40 days of purchase and very little use, the outlets no longer worked and fuel is leaking somewhere. Waited another two weeks of trying to reach someone that can tell us where to take it for warranty work, and when we dropped it off (not very easy given the weight) they said that shipping parts are not always covered under warranty and had to provide a deposit. Really? You made the defective machine. Waiting now to see if they can fix it. Use your machine within the 30 days return policy for the store, that way they can deal with the manufacturer if it breaks. Hope I get it back before summer is over, the whole reason for buying it in the first place. July 23, 2013
