Anyone run a generator on the Toolcat 5610 hydraulic PTO?

[Xfaxman]

Thinking about getting a Winco 10 kw PTO generator for use during a power outage.

Wonder about continuous running on the G Series PTO rated at 25 horsepower.

X....I thought of the same thing and have been trying to find any info on it. The PTO seemed to run my rotary cutter fine but a generator needs a constant speed. I have yet to read anything on line so far to answer the question....will it work. I hope someone responds....

the generator will put out different frequencies as load is applied, because the tractor don't have an automatic speed control, other than that, it should work fine.. I'd suggest getting a 10KW generator combo instead. it'll keep 60 HZ under load..

You mean the pto speed isn't controlled when loaded, with the engine governor, like all other tractors?

I don't know, that is why I started this thread. Since you can't use the front aux hydraulics at the same time as the hydraulic PTO, I think they use the same pump and it handles the 7' brush hog on the front pretty well.

The PTO:

I'm betting you won't have any problems at all...

It's amazing to me, how many on this site don't know that their tractors have governors!

Some even argue that THEIR tractor can't run a pto gen set, because THEIR tractor doesn't have a governor...

It would be quite inefficient. Firetrucks often use a hydraulic driven Generator. (Often Onan) Don't get so worried about exact speed. Probably nothing in your house cares. Maybe UPSes won't accept something too far out of freq.

An alternative would be to run a three phase generator, make DC and run an inverter. That's how my Onan Quiet Diesel set does it. It would also allow you to run slower rpms depending on load.

The nice feature the 5610 has is the digital PTO rpm reading on the dash. As you use the PTO, you get a direct reading on the rpm it is running.

25 Hp = 18.65kW, so it should have more than enough power to turn generator at full load and hold rpms/freq.

Easy now Sawyer Rob. Not everybody has rebuilt or learned theory of injector pumps. That's why people come here. To learn.
...you do have a point about arguing...

Yep, need to borrow a three point brush hog, watch the PTO RPM display, get into some thick stuff and see how much it drops.

I can also monitor the pressure from the pump while mowing with the SSQA brush hog:

-------------------------------------.

Thanks, one reason that I am concerned is the previous F Series model was rated at 30 horsepower and I only used it with a post hole auger on one project.

Don't know what Bobcat changed causing a lower PTO rating.

Hope to hear from some Toolcat owners that might have had overheat problems with the hydraulic PTO.

 

[ruffdog]

I never had a heat problem running a 5ft cutter on the back. The pto rpm numbers bounced around quite a bit because the gauge is reading and changing the numbers quickly. I'm just trying to remember how much the numbers changed though.....maybe 20 rpm? If I knew someone with a generator I'd crank it up and test it.

Who cares what the pto variation is ? Get a Kill-O-Watt from Home Depot and monitor frequency and voltage ranges under heavy electric motor device load. These are the parameters that count.

PTO variation when the electric load increases would cause the voltage and frequency to go lower. The Kill-O-Watt doesn't prevent or correct that.

My question is how much does the hydraulic PTO vary with a changing load? It might be less than a mechanical PTO on a tractor.

Most of the PTO generators have a built in monitor:

 

[zzvyb6]

Sure, the Kill-A-Watt doesn't correct it. It shows what the magnitude of change is. So, run the play with a suitable attachment and walk it down. My expert guess would be that a hydraulically operated drive shaft would have faster recovery than a fuel control system on an IC engine. This is for several reasons: Hydraulic closed loop feedback systems have short time constants with satisfactory damping factors. They are much less likely to oscillate, too. Secondly, these are fairly new machines where a design team probably has already considered, tested and evaluated the rpm control of the PTO using engineering standards and procedures. My only concern would be cooling capacity of the oil radiator(s) under continuous long term use. PTO generators can be expected to run for many hours at a time with the tractor stationary. This too could be checked by a simple measurement.

I’ve had heat problems with the hydraulics on my 5610 on standard flow. On high flow or using the PTO, which used high flow, I’ve had oil temp. warning in as little as 30 minutes on a warm day. I’ve mostly used the PTO with a 65” rototiller.
