Generator PTO vs Gas Engine Generator

inverter nice and quite though.. hungry.. but quiet.. could double as a heater on a cold night..

The three-point arms are made to hold an implement that is being run on the PTO. How much torque do you think a tiller puts on the arms? What good would the PTO be if it was capable of torquing off the three-point arms?!

My interpretation of the twist is the play that in the 3 point arms and the top link.

I know when I first fire up my brush hog it does move the 3 points a bit on initial engagement.

Yep, torque is torque...but twisting or breaking the lower link arms isn't going to happen...
Now, a caveat..if an idiot hooked a subcut PTO up to a Cat 3 cutter, something could break.

I have read the trailer type (the ones not connected to the 3PH) can rotate from the PTO torque if not bolted down to the trailer.

That is 'theoretically possible if you are starting to power up a small department store with a very large freezer section (or lets say a grain dryer to be realistic). When you throw the breaker to engage the load, the emf retarding torque can be large. On a home, that could be because the furnace is out, the well is out, all your electronics chargers are on, and you might have forgotten to throw the mains. But, a single hitch on the drawbar won't resist this torque. The trailer axle width does. My 50kw has breakers on the 3 phase taps, the single phase 220 output stove plug, the genny field coils and the 120v convenience outlet. The breakers will open before the torque gets large enough.

On my diesel F935 hookup, I don't even bother with the tongue attachment. The only thing you would notice is the motor governor burping when all this demand is encountered. All the gen-set waxers would probably want to carefully engage each panel breaker one at a time until they have enough stuff working in the house. Otherwise the tires might get dirty when she digs in. If this happens at night, the neighbors might discover it before you do and the subdivision newsletter report could make you the laughing stock of the 'hood. OMG....

Yea I know it wouldn't break them, but the play will let it shift some. That's what I thought the question was about. Wouldn't that cause issues? My thinking that it could cause some, probably minor, frequency variations for a brief period. Probably not something to worry about.

sounds like the 3pt doesn't have well adjusted stabilizers, or toplink.. and/or the lower 3pt lift arm balls are loose.

On my 660 and 8n.. both have stabilizer bars on each sid eof the 3pt, plus stay bars.. plus toplink.. and all ball ends are good.


when i start up the genny, under load.. the engine hits for a sec as the gov picks it up.. then it's off and running.

no jiggle / jangle play back there.

IMHO.. that much play back there will beat the tractor up if you have a real implement on it swinging and beating around back there.

sounds like some people need to address their rear hitch?

Could be. I was just pointing out that whole 3 point question may have been about the play in the 3 point.

Yep, probably not something to worry about...there's nothing on the 3PH that is made so precisely or delicately that you'd see appreciable wear for years of operation.
However, just ensure the genny has a stout enough stand to keep it in place.

I have a 30kW PTO Generator but I'm looking at a 35 kW Generac liquid cooled natural gas powered generator with an auto-switch. On June 29 we got hit by a big storm and then we had 9-days of no electric, my tractor went thru my 100-gallons of fuel and thankfully I had a friend who had access to diesel to refill my 100-gallon tank. The tractor split duties of cleaning up my property with over 24 trees (virgin timber - huge) and keeping the 100+ degree outside temperatures at bay by powering the PTO Generator running my whole house electrical needs (Two - 5 ton AC Units, 3 Frig's and of course the wife's hair dryer).

The price of NG is half of that in Diesel in WV so the cost to operate for extended periods is cheaper as well not to mention the Tractor's R & M cost from extended run times in that kind of heat. Another issue to consider is when I'm not home my wife can have electric immediatly should a power outage occur which has averaged 4-times per year for the last 14-years.

Mine was out for 9 days. It was a mad house to find gas but diesel was a lot easier to find. Did you lose power when Sandy blew through?
