what is the maximum rpm this generator can be run
-
NorthstarExpert12· 3 years ago
A maximum RPM is not listed because the generator needs to run at the 540 RPM pto speed/3600 RPM rotor speed to produce the 120V/60 Hz cycle output. Anything out of this range will put the Hz and volts out of the standard range.

it should be kept close to 540 PTO RPM or there will be non standard voltage and frequency output.

At what engine rpm will the generator produce its maximum power
I have a a 30hp kubota tractor that has a minimum 540rpm pto, but I want to know at what rpm I will have to run the motor to get the 13,000 watts?
-
NorthstarExpert12· 3 years ago
The maximum power output of 13,000 surge watts and 12,000 rated watts can be achieved as long as it is connected to a tractor rated for a minimum of 24 HP and is equipped with a PTO running at 540 RPM. The RPM of tractors varies, please check with the manufacturer to verify what RPM of the tractor will produce 24 HP.

I think it depends on your tractor. I have John Deere 55 HP tractor, and run in midranged gear at about 2200 rpms to keep it in the green. The indicator on the unit will tell you if you are there.

Trying to figure out I it has a 50 amp 220v receptacle. It looks like it does just not the lock in type but hoping someone can verify. Also looks like I need a stand and probably a dedicated drive shaft. Anything else I may need to be up and running?
1 answer-
NorthstarExpert12· 3 years ago
This PTO generator is equipped with a 50 Amp (A) Straight blade (NEMA 14-50R) receptacle. It is designed to mount to a reinforced concrete slab or PTO trailer. A PTO shaft with a 1-3/8" diameter and 6-spline input shaft like item 31919, item 31921 or item 31925 is required. If the generator is to be connected to a building to provide back up power, a transfer switch, installed by a licensed electrician is also required.
