Pro generator

[Ihandy]

Hello everyone, I am currently working on mounting a Winco model 2FS2PC Dash 1/B generator at the back of my car with fast hitch. I had been searching for a while to find a pulley driven generator and finally came up with the one that was local to my area the question I have is, I am running a 4 inch Sickle mower pulley in the generator has a 3 1/2 inch driven. What size pulley do I need to go to get the RPMs of 3600 to run the generator correctly. The reason I have to run a 4 inch drive is because the cub has fast hitch

if you use the right angle drive you can run bigger pulley, that is how its done with a fast hitch and belly mower from IH

You need to know your engine RPMs for computing the size for both the generator and the tractor/pto.

Example. Engine/PTO = 1200 rpms. Generator = 3600 RPMs. Then the engine pulley diameter has to be 3 times the diameter of the generator's pulley.

Problem. The engine RPMs has to be almost exact to operate the generator within it's specifications.

Just some things to think about a generator on a cub. I thought about doing this for a while. The more I thought about the less I liked the idea

First, You are taking the tractor out of service to generate at best ~5KW of electricity. Used 4-6 Kwatts generators are around on the Facebook marketplace. Your generator is about 2KW and those are even more available used.

Second, you are racking up hours on the cub engine. You may be able to run a 2KW generator at 1200 as Eugine suggests but you may end up more like 1600 -1800 for anything larger or a full load on the generator. The output voltage may fluctuate too much to be practical if the Cub engine comes under load. You have to make sure the engine is operating at a good part of the power curve to easily handle the load

Three, parking the cub while running the generator and it out of gear. The parking brake is questionable - so you have to chock the wheels

I concluded that a portable generator on a heavy farm/nursery wagon or on a FH carryall worked better for me.

I have 3 portable generator sets. One small that I can throw in a trailer or the JD Gator and trim trees. Two larger ones that I can run houses during commercial power outages and take to construction sites to power demolition hammer/jack hammer, large drills, compressors, etc..

Generator sets frequently come up at auctions.

Commercial generator sets have a function to exactly dial in the engines RPMs. That's important to keep the voltage from fluctuating.

Thank you for the replies I’m trying to talk me out of doing this project however, this morning I managed to build the bracket tree to mount it on the final drive and everything came together nicely. I even tested it out and some smaller appliances since it is a small generator are used fan and then I tested an angle grinder and they worked well. Also, I think I need to get a little bit more RPMs out of the tractor which I can do by adjusting the throttle linkage. If all I need it for is an emergency to run a sump pump or even a lamp at night that’s all I’m asking for so it’s working good. Also I can use it in the marsh to work on deer stands overall I am happy with how it turned out

. . . get a little bit more RPMs out of the tractor which I can do by adjusting the throttle linkage. . . .

If you intend to do that by changing the linkage from the governor to the carburetor, it won't work. That needs to be set by the book (in the Owner's Manual) for the governor to work properly. You adjust RPM with the bolt that is screwed into the top of the governor.

I would consider changing pulley sizes. The max torque on the c-60 is around 1600 and it falls off with more RPM.

You want the engine and the generator to operate where they are most productive.

What is the voltage you are getting out now? How much more do you need?

[Matt Kirsch]

What did you end up using for a pulley on the generator?

With a 4" drive pulley on the PTO you need a driven pulley of 1-3/4" on the generator running the tractor at 1600RPM under load, which is pretty realistic. That's awfully small for a B-sized V-belt.

I’m not going to be adjusting the governor instead I’ll be changing pulley sizes on the generator I did a test with a cut off electric cord hooked up to a tester and plugged it into a outlet and it read 42.4 then I plugged it in the generator and it tested out 39.0 with the tractor at full rpm’s so I’m really close I currently have a 2 1/2 inch pulley on the generator so I was goin to buy a 2 inch pulley and then try that and test the output

[inairam]

42.4 and 39 what? What units?

[Eugene]

42.4 and 39 what? What units?

Volts. I think the gen set is rated at 16 amps.

so I’m really close I currently have a 2 1/2 inch pulley on the generator so I was goin to buy a 2 inch pulley.

Nope. Not any where near close.

You need to figure/math the pulley sizes and engine RPMs to get the gen set to 3600 RPMs. You have to be on or very close to a constant/steady 3600 gen set RPMs which equals 120 volts at 60 cycles.

Eugene, he said he "plugged into an outlet" - Assumed it was a standard on-grid 120v outlet. I can not understand 42 anything from a wall outlet.

??????????????????????

Reread the post a couple of times. I assumed it was plugged into one of the outlets on the gen set. The gens set probably has 2 each 120 volt receptacles.

Got to be volts he was reading. Can't be Ohms and 40 amps is beyond the gen set capacity. Also, beyond the ampacity of standard/common household electrical circuits - fuses or circuit breakers, receptacles.

Ok. I don't know.
