Q: Hi, I am seeing the same Winco 25kW PTO generator in a brushless model on ebay. Do you have that model available?

by Jeff from Minnesota on November 24, 2013

A: Per the Winco specification sheet this model is only available with the brushed type alternator/generator......

RAB Type - Rotating Armature Brush Type

Specification Sheet

by Mike, Product Expert
Q: My 2013 Diesel Ram 2500 Pickup was purchased with the PTO Prep Package.

Do you offer any products that would allow me to connect a 20KW+ PTO Generator to my truck?

by Vincent Britton from Florida on September 09, 2013

A: Thank you for your interest in Electric Generators Direct!

While the vehicle connections will vary from one manufacturer to the next, you will most likely require a tumbling bar and possibly a six-spline adapter. Each of these you can find listed below...

Six-Spline Adapter

540 RPM Tumbling Bar


by Mike, Product Expert
Q: I'm interested in a PTO generator. I like the Winco 25PTOC-3, but the specs say a 50 HP tractor is needed. Mine is 45HP. Is that enough?
by Bob Williams from Arkansas on February 12, 2013

A: Sorry, your 45HP tractor is not enough to properly power the Winco 25PTOC-3 generator.

Proper sizing is based on the PTO HP and is sized as 1000 watts for every 2 PTO HP.
by Mike, Product Expert
Q: What type of oil is used in Winco 25PTOC-3 generator?
by George. Lewis from Virginia on August 20, 2012

A: Check the generator gear case oil level before each use of the generator. Maintain the oil level at oil level plug height.

The generator is shipped with lubricant in the gear case. Specifications for gear case lubricant are:

API Service: GL-5
Grade: SAE 85W-9O-140
Amount: 2 pints

The following kinds of oil are recommended for use in the generator gear case:

Mobil SAE 85W90-140 API Service GL- 5, Sunoco/DX XL80W90-140 Kendal Three Star 85W-140, Amoco 85W140 or equivalent.

CAUTION: Equipment Damage

Do not overfill generator gear case. Overfilling causes overheating and oil seal failure. Change the oil at least once every six months. Change it more often if you use the generator in bad weather.

by Mike, Product Expert
Q: What's the PTO horsepower needed to run the 25 KW generator and what iRPM should the tractor be set at for normal operation?
by Ed Hensley from West Virginia on July 23, 2012

A: This unit requires 50HP at the PTO as the sizing rule of thumb is 2 PTO HP for every 1000 watts.

The RPM will vary depending on the load.....

Start the tractor and use the gage on the generator to set your rpm. Then and only then apply load.

You meter will drop then adjust your tractor rpm (idle) to the green zone.

There is a small boost on that generator for an up surge in power so tractor RPM does not need to be changed if a surge is required.


by Mike, Product Expert
Q: How many rpm's does your tractor have to turn to run this generator?
by David from Virginia on July 12, 2012

A: A rather complicated question but here goes....

Start the tractor and use the gage on the generator to set your rpm.

Then, and only then, apply load.

You meter will drop then adjust you rpm (idle) to the green zone.

There is a small boost available on the generator for an up surge in power without idle issues on the tractor.


by Mike, Product Expert
Q: Jim - What transfer switch will the 25ptoc-3 require to be able to hook up to my power pole and run power to my house and outbuildings.
by Dallas Neumann from Idaho on March 19, 2012

A: The following 100A and 200A outdoor manual transfer switches are available to work with their PTO generators....

Winco 100A Outdoor Manual Switch

Winco 200A Outdoor Manual Switch

by Mike, Product Expert
Q: Jim - I have a JD 5410. I believe the PTO is rated at 65 HP. I would like to be able to drive entire house including water pump, heating, and all electrics. What would you recommend? Thanks. Joe Adams
by Joe Adams from New York on March 12, 2011

A: The largest PTO generator you can use is 32.5kW which is based on 1000 watts for every 2 HP. The larger the generator the more items you can power and less stress on the unit. Winco does produce and exceptional product and this 25kW model would work great in your application.

We do recommend that a certified electrician validate your wattage needs to verify this unit is not undersized.

Winco has been a manufacturer of quality PTO generators since the 1950's with the original goal and purpose of keeping American farms operational at a time when frequent power outages were the norm. Their PTO generators are reliable, safe and sought after to this day.

This 25kW from Winco offers you more power, but will require additional HP from your tractor. The rule of thumb is that you need about 2HP for every kW of power. So in this instance you are looking at a minimum of 50-HP... more

From The Manufacturer
25ptoc-3
The 25PTOC-3 has been certainly our best-selling PTO generator. This generator comes with great features such as maintenance free bearings, Square D circuit breakers, protective PTO shield, Lifting eye and a 4-wire Anderson full power plug included. The cast iron gear case has a 540 RPM, 1-1/8th inch keyed input shaft. A purchase of a spline adapter is necessary to convert the input shaft to fit a 6 spline power shaft.

Winco 25kw Pto Generator Great Product, Would Recommend
Got it home and put the PTO shafts on. And for the next. 9 days,we were out of electricity. Ice storm #2 since thanks giving, for a total of 19 days without power. My Winco generator performed great. I am more than pleased with it. Wished I had bought it earlier.
Pros: Easy To Use, Price, Exceeded Expectations, Reliable

Heavy Duty Very Industrial
Great generator and works as advertised. I hooked it up and it powered my whole house for an hour just as a test run. I ran my heat pump, deep well pump, two fridges and a chest freezer and various lights throughout the house. Appears to be as advertised. I was only pullig about 30 amps on each leg on my run. So it had a lot more left. The tractor ran as if no load was on it. The rpm rating of 540 at pto is a little deceptive. I have a John Deere 5103 and I have to run tractor... more

This Has Been A Life Saver
This past year from Thanksgiving until the end of the year, we have had two major ice storms in central Oklahoma. The first one we were without electricity for ten days, line's and broken poles every where, I decided then to get a power take off generator.

The Winco 25 KW was my first choice. I ordered it and got it on the 24 of December, I got the tumble bar the same day, got it put together without much trouble,and the day after Christmas we had our second major ice storm. This time we... more

Great Product
I ordered my 25 kw pto generator just before Christmas this past year. I got it and my tumble bar on the 24 of December. Got the generator mounted on my trailer I had reconditioned just for the generator and tumble bar mounted. The night of the 25 of December we had a major ice storm in Oklahoma, never in my life have I seen so many miles of power lines down. I hook my generator up to my L4400Kubota and ran it for 10 days straight. What a life saver my 25 kw generator has been. Wish I had... more

Good Unit
I bought this unit back in August, so a bit delayed on a review. As this was a major purchase, I did a fair amount of research before buying this generator including calling Winco. I found the PED expert's expertise did not run very deep, but I'm happy to report the Winco sales folks were glad to talk, and as expected - do know their product "in and out". I will say the Winco team had good things to say about buying through PED so I made the purchase from PED and saved the shipping... more

Gear Oil Plug Issue
The gear oil plug in my new generator was so tight that I could not get it off with a regular wrench. It is a 7-16" square plug head. I tried all the methods I had used in the past to no avail. A regular 7-16 box head wrench would just slip off because it would not seat all the way. So I called the customer service POC of the generator company and was told I need to get a square socket. Good advice if you have one or can find one.

Since I did not any square sockets, I started... more

Upgraded My Old Pincor 13kw
I inherited my fathers old 13Kw Pincor generator. It wasn't big enough to run my new house and the circuitry wouldn't allow the frequency and voltage to match up properly.

The 25Kw Winco handled the load at the right voltage and frequency.

Please note if you order one you will need the PTO shaft adapter.

The generator comes with just a smooth 1-1/8" shaft that is keyed and drilled.

Works Good
I had order my Winco and received it 2 weeks later. I unloaded it and about 35 min later had the frame for the 3 point put together and ready to hook to my Tractor. The gear oil plug is tight and very difficult to remove to check the oil level. I connected it to our outside power pole service disconnect. I am running my whole house on a double 100amp breaker. The generator has handled my 2200 sq/ft house with two 3 ton AC units, water heater, water pump, two refrigerators, deep freeze and... more

The Best Generator And The Best Company
I recently bought a Winco 25kW PTO generator from Electric Generators Direct. Jim Baugher is the GREATEST. He is extremely knowledgeable about all generators especially PTO Generators. I ordered over the internet but Jim called me at my home to be sure the order was complete.

He worked with Jeff Harmon at the Winco plant DIRECTLY by phone and email to get me the right generator and accessories.I had some questions after I got the generator and called Jim at EGD. I spoke with him directly,... more

Great Product & Great People
I ordered the 25ptoc-3 along with the PTO adapter. Everything arrived earlier than projected, ready to hook up and go. I mounted on a 3 point carry all. Works great. I had some questions before and after purchase and tech support was very timely. Look for the anderson plugs on the internet. I am considering ordering another one smaller and will definitely buy from EGD. Cudos to ABF freight also. Was the best.
