RPM's while working

[dmay]

Thats a good point. My 2320 is at full throttle to get it to 540 RPM on the PTO............ Any other 2320's out there different?

The 540 PTO marker on the tachometer is simply a reference line pointing to an RPM mark. On my 2320 I believe it points to 3000 RPM. Full throttle for me reaches 3200 RPM. So PTO mark for me is 93% of full throttle. Not sure of the exact RPM numbers but I know for sure that I still have some power to go beyond the PTO mark.

My Foton/Perkins engine PTO speed is 2,000 rpm, that works out to be 88% of max.
I would conclude that if you don't know what speed to run the engine for 540 rpm a good ballpark number would be
85 to 95 % of the engine max.

personally don't like running any sort of engine at full max throttle non stop.
1/2 to 3/4 idle is what i normally run. now don't get me wrong. if i have mower on. and i am about to go through some thick dense wet grass. i will max it out. but after i get past that i will drop it back down.

In general I find all engines live longer, happier lives when throttled back from full throttle. On my tractor I set the speed at the RPM rated position when snowblowing. I can encounter heavy drifts that can certainly bog the engine down. My guess is if I jammed it full throttle and just pushed forward something expensive might occur. I prefer to let this be an indication I'm pushing too hard and slow down to let the blower work through clearing the snow.

Is the PTO mark at full throttle? I don't have a 2320, so I don't know.
All three of the tractors I've owned had the PTO mark (on the tach) a few hundred RPM below full RPM.

We need to differentiate between full throttle and full rated [governor contolled] rpm. When you set the full no load speed you get Fast Idle. Actual Throttle is very low until load is applied, at which time more fuel is automatically called for by the governor to produce the power to hold the set rpm.

Had some seat time today blowing snow. Confirmed on my 2320 that my PTO mark is at 3000 RPM and full throttle for me is just above 3200 RPM.
