2 things. Thing 1. Ditch the plywood and use angle or channel as a foundation to mount the genny to. Thing 2. Don't leave your power cord from the house to the generator all coiled up. I work at a major pharmaceutical company and we hooked up a giant diesel generator to run a building during a site shutdown. The 500MCM hookup cables didn't need to be run very far to hook the generator up to the building so they left the cables coiled up on a pallet and just hooked up each end. After a couple of hours, someone smelled something burning and it was the coiled up cables on the pallets. It's the same principal as energizing a solenoid coil without being over the armature...gets hot in a hurry.

[@HomesteadEngineering]

Good "things" to know. Thanks!

A true representation of how much how horsepower it takes to make electricity

[@HomesteadEngineering]

Yes! I am thinking of actually using it to measure just what the current horse power of my tractor is by ramping up the load and finding where it fails to supply the load. I am guessing I could get to 5000 watts, 10hp. 2hp for every 1000 Watts. I'll report back the results. Thanks!

[@rongray4118]

Fantastic video! You solved your "pros and cons" by installing a system with battery back up. You don't need two tractors! My wife and I are preparing to build an Earthship Biotecture style home in Northern Nevada...this is a means to generating power until the 4.6 kilowatt solar is installed. Blessings and Good Cheer to you and your family!!

[@HomesteadEngineering]

So this system will get you by until you get your battery backed solar. Once you have that, this system will work great but of course by that time you won't need it. That's life... :)

[@thatguyc5899]

Dave, I built nearly an identical setup about 6 months ago. I used a Winco 10kw (made in the USA), and the same carry all. Winco wanted $650 for their gen carrier. As others have said, I would not use it for continuous power but running it a couple of hours a day to keep the freezers cold and other items charged is all one really needs to do.

[@HomesteadEngineering]

Yes, a couple hours a day should do the trick, The way I am using it, I only need to run it a couple hours per week and I with 200 gallons of diesel I expect I could go for about two years without utilities. Thanks!

This is my exact set up. I have a propane connect right under the plug that goes to my solark generator connect. I can use my ck2610 tractor or my propane portable generator. I store 150ish gallons of diesel and my cooking is from propane with a 330lb tank.

Update: If your connecting this to your house via a transfer switch and pass the neutral and ground through to your main panel, then you probably should not ground it at the generator. Consult an Electrician. Thanks!

I run the 10000 on my 1025 deere it runs the house and the barn just fine. The tractor does use a lot of fuel. I bought a fifth gallon portable tank with a pump to keep the fuel close to the tractor when it’s hooked up. But they work great.

[@jimmotormedic]

I would have thought that the tractor would have a governor that would compensate for various loads. Loading that engine down a bit won't hurt a thing and is actually beneficial. We run a kubota rtv since new and has just shy of 10 k on it. Runs a minimum of 3 hrs a day 365. From time to time I hook up something heavy to it a give it a good long run under heavy load. Smoke starts out blue then grey then black, cleans up and it loves it. Great little engine

[@HomesteadEngineering]

I love hearing accounts like this. I do baby my equipment a bit but on occasion I do run them hard so I like hearing from folks saying that its OK and they have done it plenty with good results. Thanks!

[@BluesTheBestBoyIGuess]

If you plug it into your home circuitry you don't need the ground rod, It grounds through your system. Just make sure the 240 circuitry/receptacle is grounded to your breaker box. The ground rod is only required if you run it out in the field or if you run an extension cord that's not grounded to the house.

[@HomesteadEngineering]

I agree. Thanks!

[@ulhpilot7757]

It’s called neutral bonding, but check your manual to be sure.

[@thegrumpyyooper6503]

Just a suggestion. The generator is designed to run at a steady 540 RPM so instead of messing with the throttle set the engine RPM’s so they are just above the engine RPM needed to maintain 540 RPM to compensate for the surge when a load is added. The other thing to consider is by not running the generator at its designed RPM when there’s a load on it you’re going to put a serious load on the generator with the possibility of burning the generator out and damaging sensitive electronics in your house by giving them too low voltage. When I had my fifth wheel I had a surge protector that would cut the power off if the voltage dropped too low to protect the electronics in the fifth wheel the same principle applies here as well too low voltage is just as dangerous to electronics as a massive voltage surge. Burning a few extra gallons of Diesel is a lot cheaper than replacing the generator and damaged electronics.

[@HomesteadEngineering]

Hello David, the problem is that you have to adjust the throttle to maintain the 540 RPM. This tractor and most tractors do not have the ability to maintain the RPM under varied loads. When large loads are added, the RPM drops and you have to adjust the throttle to maintain the proper RPM. When large loads are removed, the RPM shoots up past 540 and the throttle must be reduced. The way I am using it, I just keep the load constant for 2 hours while charging my solar batteries. That eliminates the problem. Thanks!

[@thegrumpyyooper6503]

The tractor should compensate for the load on its own to some extent because the fuel pump has a governor that should increase the fuel to compensate for the the extra load. If the tractor is not adjusting for the load on it’s own the governor may be stuck and not allowing the pump to adjust the fuel for the load. The other possibility is engine is starting to get tired even on the bigger AG tractors 5000+ hours is a lot depending on how they’re used/maintained and will start to show a decrease in performance.

[@KALI1080]

​@@thegrumpyyooper6503 The governer on a mechanical garden tractor engine is not going to work well for a generator. This is shown in the video. Gensets use isochronus governers. Isochronus governers maintain the speed of the engine regardless of engine load. This tractor does not have an isochronus governer. I would bet that generators like this would function better with a newer tractor that has an electronically controlled fuel system, as engine speed does not drop when load is applied.

[@DMahalko]

Generator RPM is not all that critical. The charge controller does not care at 9:25 that the frequency dropped way down and keeps accepting it, no problem. Modern electronic devices with switchmode power supplies do not care much about the frequency or voltage. Induction and synchronous motors will just run a little faster or slower. Power utilities keep a tight leash on frequency because their customers are annoyed by the flickering of incandescent lights when large loads are turned on and off, and also because old mechanical clocks used synchronous motors that exactly followed the grid frequency. To keep the time correct on these clocks, the grid frequency had to average out to exactly 5184000 cycles every day. If the grid voltage went up too much, incandescent lamps would glow brighter and brighter until they rapidly burned out from running so hot. A "brownout" meanwhile is when voltage drops, and incandescent lamps glow dimmer, changing the color from white, to yellow, to reddish-brown.

[@ulhpilot7757]

It’s because the tractor is under powered. My JD 1025R runs my 10KW PTO generator without needing to adjust engine RPMs regardless of the electrical draw. I set the output at slightly over optimal rpm’s and leave it.

[@TheSHOP411]

Instead of hanging the generator off the back of the 3pt frame, shorten the PTO shaft. It’s not that hard to do. Also the long shaft is dangerous as it could damage the tractor PTO housing if the shaft is jammed into it.

[@HomesteadEngineering]

Probably not a bad idea to shorten the shaft and move the generator forward on the 3 point. As it is there is plenty of play in the shaft so as not to jam. Thanks!

[@wildbill23c]

That's a really expensive cell phone charger LOL. That's a great setup, for like you said if you have multiple tractors so your only tractor isn't tied to your generator...although in a pinch its not that hard to unhook and hook back up if you needed to use your tractor to remove snow for example, then hook back up to your generator when you are finished...but having a dedicated backup generator would be the only way I'd go, if I had propane on site...in a power failure I'm not sure how natural gas supplies might get interrupted as the pumps probably shut down too I'd assume. I have a 225 gallon propane tank that just my furnace runs off of, if I got a backup generator I'd go with propane and just have a larger tank brought in. I don't have a tractor so a PTO generator wouldn't exactly be useful for me LOL. I do want to get a tractor just a lot of other things have gotten in the way this year, and its been 30 years already so what's another year or 2 waiting LOL.

Be careful that you aren’t grounding the generator when you are plugging it into a grounded system. You only want one grounding path. If you have two when something happens you could energize the generator and the ground around it.

[@HomesteadEngineering]

I believe that is correct. In general, I would ground and bond a generator when used stand alone and not ground or bond it when connected to a transfer switch. That is because the ground and bond from the generator will usually pass through the transfer switch and be grounded and bonded at the main panel. Thanks!

Today, Systems typically have two paths to ground. One a domestic water supply and two a driven ground rod. Depending on impedance, you may have ore than one ground rod.

My uncle had one of those 80s early 90s hydrostatic b7100s, It had a 2 speed pto. . Is it possible you didn't have it in the 540 speed? Usually rated engine speed for a set pto rpms is quite near high idel, or maximum rpms of engine. The engine just sounds closer to mabe 2k but I could be wrong. Though it's interesting to consider running a light load with a gen at rated speed, but under speed the engine for possibly reducing fuel use a smidgen. 0.01c

Recommend pto) Is that some kind of problem?

[@HomesteadEngineering]

KB, As long as the PTO shaft is turning at the right RPM it should not matter how much HP the tractor has. I don't see having too much potential HP as being any kind of problem at all. You simply won't be using all that extra HP. Off the top of my head I think it takes about 2 HP for every 1000W of electricity. It will probably be a bit less efficient but it should work fine.

When I am actually running the snowblower that shaft is turning at 2600 RPM I was hoping I could design some type of generator head that could directly couple between that shaft with a universal joint and run at the engine speed but generator heads either run at 4 pole 1800 or 2 pole 3600 rpm But I could set the engine lower and always raise the RPM with a gearbox for a smaller generator head.

This is really inefficient. Whatever money you saved not buying an engine generator will be spent in gas. Generators are set up by the manufacturer to be well matched to the engine and you get the highest BSFC possible. Not to mention inconvenient. Also, if your load drops, you could have a blown engine. If you have the throttle up to deal with a high load in your house and that load disappears, there is no governor to close the throttle. These are meant, so far as I can tell, for remote farm work.

[@HomesteadEngineering]

It has been my experience that the PTO running off my tractor uses a lot less fuel than my engine generators. I would guess maybe 0.6 gallon/hr. Dropping the load would result in a near instant increase in throttle. I don't think this would result in a blown engine unless you were at very heavy loads and not present. You do make a good point though and something folks should be aware of for sure. Thanks!

As a fellow B7100 owner I was curious as to how the tractor would perform. They were built like tanks but lack the higher hp of today’s tractors of similar size. Evidently the internal governor cant match the power demands of the generator as it would with a mower or tiller. The generator rpm needs are too sensitive. From what I’ve been told the general rule of thumb for engine hp to generator wattage is roughly 2 hp per 1000 watts. The b7100 according to kubota is 16hp at the flywheel and 13 at the pto. So you are probably maxing out the engine around 6500 watts and considering the hours on the tractor the actual power numbers might put you down closer to 5500 watts. If you plan to keep it on generator duty you might want to consider adding a water temperature gauge to the tractor. A simple method would be an inline adapter to hold a temp sensor in the top radiator hose. The majority of the D750 engines didn’t have water pumps and used thermo siphon technology. They like running hot.

This was the first time I tried it. In the future, I will just crank it up and drop about 3,000 watts on it and leave it there. No adjusting. Thanks!

I dropped a D950 in my B7100, That extra HP makes it a beast. Full set of gages, Alternator with a real water pump. I push snow with it, never bogs, nothing stops it except loss of traction.
