Generator head for the CC

I have a CC 128 and a 129.
I want to mount a generator(generator head) to the front and use the front PTO pulley. Hang on the front, gen. shaft under the grill....
I want to use the 2600 generator from Northern Tool and Equipment. Pincor use to make such....just for attachment to these lawn tractors
I see numerous setups like this on the internet
Has anybody out there done such?
What size pulley?
How fast does one run the engine? They have 12hp
What is the rpm of a CC engine? Let?s say at half throttle....
The generator is to be run at about 3600rpm for optimal output
I can rig up a mount using the mower deck front attachment...unless someone has another idea
I?m trying to get away from a portable generator that would have to be started once a month (should be!), stale gas, additives, and just sitting around.
The tractors get used frequently, one for mowing, other for plowing, snow removal and general yard work
Thx in advance for any discussion on this and for your input..
 
Likely, your GT engine runs 3600 RPM's at full throttle, so the pulley size on the generator would need to be the same size as the one on the engine.
 
I am thinking that back in the day some company offered a front mount generator for a CC. I bet there would be a picture in the 'allied equipment catalog' on IHCUBCADET.COM. finding one might be out of the question.

I am thinking those K-series engines were originally set up to turn about 3200 rpm at wide open throttle. I am thinking that any generator head you get now will want at least 3600 rpm. (Briggs and Stratton specifies 3750 no load for theirs.) So you want to be turning 1.125 faster than the crank pulley, if my math is right.

So if, lets say the pto pulley on the engine is 4", then you want your generator pulley to be about 3.5".

Your actual power generation capacity might be related more to how much torque your belt can transfer than the engine or whatever the generator unit itself can develop.
 

You need about 2hp per 1000 watt.
My belt driven generator is a 4000 watt and my 917 Allis garden tractor is 17hp so I belted it so the engine does not need to run full RPM.
I have a volt meter and set the throttle so it puts out about 130 volts.

I looked at the Northern tool website, and it says horsepower required is only 5, so you could overdrive it a little, and run the engine at a lower rpm, BUT! Then you would have the danger of producing higher voltage and frequency. If you have a meter (kilowatt) and only use it yourself you could do that, but probably shouldn't!

That works, and is usually good enough, but it's better to use a cycle counter and adjust the throttle for 60 hertz.

That's true if setting throttle while under constant load.
But my loads come and go. So this is the way I set it under no load, and my load is not fussy as to hertz/cycles.
 
IMHE, most AC generator "heads" are not rotation-sensitive, but it certainly would be "due diligence" to verify that for the specific unit one wants to use!.
 

May as well be able to use all the engine s power . Single largest problem with Home, Hobby and Farm generator purchases . The purchaser chooses a generator that is 1/2 the size of what is actually required .
Check on eBay for " belt driven generator " and "ST Generator" .

I'd put the generator on the gear drive, the 128. Put them in neutral and they stay put. My CC Hydro's sometimes tried to sneak away.
The PTO clutch pulley is an odd size, 3 and 7/8ths or some such unavailable size. Get the closest size and run your engine just a tiny bit over it's 3600 full load rpm. Get a digital photo tachometer at Harbor Freight or Amazon, $10 to $15 or less. As said, make sure generator can run both directions, or at least the right direction. Might as well get a 5000W generator, use all 12 hp.
Your Cubbies both have quick-attach, I've made several attachments to quick mount, or just weld or bolt a mounting plate to the quick attach from your mower mule drive. That's the handiest implement mounting system on any garden tractor.
 
I think it was Pincor that made the generator for Cub Cadet. Usually a couple a year come up for sale on the Only Cub Cadet web site.

es and the first ones offer thru IH were mounted on the side of the tractor so it so it did not have to be removed to use most implements.

I would look hard at doing it on the side as well with a bracket or hinge point that can stay on full time. Then be able to quickly hang the generator on it and the belt.
Do the wide frame CC's have the pully on the crank where the drive shaft connects? Changing that one to a bigger one might be an idea to look into.
 
When I bought my JD 235 back in 2001, they made a GT235E. Electric, had onboard inverter. Wish I would have bought that.🤔😟
 
The starter/generator is belt driven already on the right side, your AC generator would have to be mounted even further to the right and THAT puts it a long way from the engine. Would probably be best to drive the AC generator off the pulley on the starter generator. The starter generator runs at a really high rpm, not sure what rpm exactly, you would have to figure that out.
Every AC generator I ever saw in the IH approved accessories and attachments catalog mounted below the frame in front of the tractor. May have been one oddball that mounted on the side.
The pulley on the drive cup on the flywheel end of the engine is cast and machined as part of the engine clutch driver and driveshaft driver. That pulley is pretty small, only thing I've seen driven off it is the hyd lift for gear drive CC's. And no way to turn it off/on, engine runs it turns.

Another possibility would be getting a rear transmission PTO for your 128 and running the generator from that. Runs 515 rpm if I remember right, have to speed it up a lot for 3600 rpm for the generator.
My 982 Super Garden tractor has all the options, Cat 0 3-pt, rear 2000 rpm pto, steering brakes, frt aux hyd outlets, 20 hp Onan, it would make a great generator tractor.
 
Replying to my post and photo:
Mounted just fine
Used 32 in. Belt
Variable pitch pulley, opened 4 rounds, about 3.5 in diameter
PTO pulley 4.3 in diameter
Engine runs about 1200 rpm; generator throws 120 volts, I purchased voltmeter from Amazon. This size Pulley lets 12hp engine run about 1/4 throttle.
Mounted generator on hinged Baltic birch plywood so that weight of generator holds belt tight
Purchased tachometer for engine from Amazon
Marked throttle, rigged up a way of clamping it in place with a small visegrip...a little barnyard engineering here!
Very nice generator head I purchased from Northern Equipment and Tool company.
They have good tech and chat help.
 
Cool beans!
Looks like same way that IH did it with the Pincor generator way back in the narrow frame days.
Did you make the mounting bracket yourself utilizing the quick hitch attaching feature?

X2!

NICE job!
 
Yes, that quick hitch is a handy deal. I use it of course for the mower deck, a blade, and rigged up a discarded one for a front end weight for when I plow. Also used that one for template in making this mount for the generator. Thx for your common interest here.
 
This is how I hold the throttle in place so that it don?t creep. Mounted an angle shaped metal onto the two mounting screws. Clamp with small visegrips. Yes, I know, it?s a little bit of redneck engineering.

Funny but effective! I've wanted to do this same thing on my 982 with the 10,000 watt Northern Tool gen head. You can't go wrong with these Northstar generators, I have had 2 of them.
 

MY as well go for the 7.5Kw. The Space Cadet has enough power to run it .
Plus better tolerance for the typical unbalanced loading . With for example . 10 amps on one side and 30 amps on the other side .
