    Default Voltmaster PTO generator

    Not sure if it has been asked yet, but does anyone have the 12K/15KW surge Voltmaster PTO genny and what do you think.
    Also can anyone who already has a PTO genny let me know if you constantly have to adjust the throttle on the tractor when loads kick on and off?

    I have a 15KW pto generator and have only tested it with a few varying loads. I set the throttle to get 61hertz and let it run with different loads. The hertz would drop down to 60hz at the lowest and I did not have to touch the throttle. My generator is the Harbor Freight 15KW generator.

    I am waiting for them to put it on sale and then will buy something else I don't need.

    It depends on a tractor. Most newer tractors have a speed governor that will keep the rpm constant withing quite large load range.

    Anybody with a 3x20 series JD run a PTO genny that can speak to the auto throttle to keep RPM adjustments?

    really no one has the Voltmaster genny? Price looks good, American Made, and looks of high quality.

    I like all the bells and whistles on the Harbor Freight 15KW but I am Leary of all that stuff failing since it is Harbor Freight.

    Then there is the debate of Brushless vs Brush? I only plan on using it for emergencies currently and wonder. If it would be a big deal.

    I looked at the Voltmaster but it was close to 2 times the cost of the HF. Didnt realize it was made in the USA. I like the looks of the Winco generators.

    Yeah but the Winco is real pricey.

    Dex, how do you like your genny, did you get it from HF or Rural King?

    Recently bought a used Dayton 12/15kw PTO generator which is a re-badged Voltmaster and I'm very happy with it.
    I run it with a kubota L4200 which has a bit more power than your JD, but at 30hp at the PTO you should have plenty as well.
    Setting the throttle to obtain 62hz with no load, I never saw it go below 60hz even with a 4ton A/C unit, a 1.5hp well pump and lights drawing power.

    If your interested, I have a thread where I discussed re-wiring the generator from Bonded Neutral to Floating Neutral. (Which I ultimately did)
    I also discussed my mounting, inlet and breaker box setup and how I tested it.

    The generator is brushless, has sealed bearings and capacitor voltage regulation.
    My understanding is this doesn't control voltage quite as closely as an AVR, but is simple/reliable and all my electronics function fine.
    If you look around you can get the Voltmaster delivered new for under $1,300.

    Hope this helps

    Thanks stoney, I like the voltmaster but just wasn't sure because I haven't seen anybody post anything about them yet or at least that I can find. My main concern is that I don't have to go out and adjust throttle everytime a large load kick on and off.

    I ended up getting the generator from HF because Rural King was out of stock (and had been for quite a while). I have only run the generator for about an hour to check the operation and to see if it would start my 3 ton heat pump(no problem).
