How do you run your tractor?

I was always taught to never run any tractor over 1500 rpms, is it bad to run it over that. But when I started working at the neighbors farm in the spring and fall. we'd run the tractors at full throttle 2200 rpms (this is on newer equipment) so what is your option? I run a oliver 1855 and a oliver 1365.
Thanks Strongs Olivers
 
Run them at rated speed, whatever that is. That's what their designed to do. How could you even operate PTO driven equipment on most newer tractors at 1500?
 
first of all it depends on the load you are pulling. light load just gear up and throttle down.just dont lug the engine and no problem.
and save some fuel.
 
No, thats what we run or Oliver's at,but now were getting out of hay and into grain. So was wondering if was just hard on them.
 
The reason I ask is because I can't pull a three bottom plow in third at 1500,and in want to get bigger tillage equipment. Like a 5 bottom plow,12'ft disc,10 shank plow,etc.
 
Nebraska Test shows the following for 1855: Rated speed-2400 RPM. Drawbar HP @ Rated (2400 RPM)-82.65HP. Drawbar HP @1500 RPM-approximately 61 HP.
Should be able to pull 4-bottom plow if you run 2400 RPM but I don't think you'll pull a 5-bottom. I agree with other comments about PTO speed at 1500 RPM. Your PTO would only be 615 RPM with 1000 PTO or 350 RPM with 540 shaft.
 
If they wouldn't last being run wide open, the manufacturers wouldn't set them at rpms that high
 
My old oliver neighbor always said never open the throttle all the way unless you had a load on it. Maybe he was just talking about the 310 Waukesha, I overhauled his 310 out of his 1950T and the engine was the only thing that wasn't worn out on that tractor. We put the engine in a real nice 1955 that had a broken crankshaft. chris
 
The only time I really worry about how many RPMs they are running is going down hill, I will not allow them to run away on the Rpms on a down hill!
 
Why are you running them at 1.500 RPM when they both are rated a 2,400 RPM and are governed. They are designed to run full throttle when pulling equipment.
 
Most of mine will never go over 1200rpm. As stated below, pto rated speed, or required belt speed, is one important factor. The rest of the time they should be run at maximum torque, provided the load is at an appropriate ground speed, etc. But torque figures were not provided on these old tractor engines. Think, too about the detroits - they needed to be at relatively high rpms just to keep innthe power band (ie between max torque and max power). So your fixed mode of operation is flawed from several angles. Following the manufacturers instructions is a good start. Even differences between gas and diesel engine operation, I would suggest. So 'sensibly' might be the best answer.
 
My dad, from the time I was 4 I was told to never told to go above that. But now that I'm run the equipment the most I run about 1700,1800rpms thanks for the reply.
 
I can say that our 1855 when under load is usually running at full throttle or a touch under, which is rated PTO speed(2200 RPMs if I remember right). Been running it that way since we got it. A few years ago it started to eat the wrist pin bushings, but it had the 2 pc. ones in, and a hodge podge of rod bolts, some 6 pt. some 12 pt. Since then, no problems and runs strong.

With most jobs, the 1855 wouldn't have enough torque at 1500 RPM to do the job, and the PTO wouldn't be running fast enough to run anything like the haybine, chopper, blower, etc...

Our Massey 285 is rated for 540 PTO at around 1750 engine rpm, and 1000 RPM at 2000 engine rpm's. Neither one has ever hurt it.

The 1600 is 540 @1750 as well, but usually runs a touch faster.

Run them at rated, wherever that may be.

If I need the power to pull the load, winder up, except the 310's, PTO speed for them ,anything else, open her up if power or pto speed needed. I'm a firm believer in the theory, shift up and throttle down.
 
In my 66 years I have never heard of such a thing as only running 1500 rpms on a tractor thats rated for much more.......All tractors are made to run at full throttle when pulling heavy loads.....On lighter loads we throttled down some...

The 1967 model Oliver 1950 pictured ran at 2400-2500 rpms in the field and 3000 rpms on the pulling track...Its pulling a #4500 24 ft IHC field cultivator and the little Detroit knew it was back there..I can't believe that I was actually running a muffler when I took this picture...

I know we're talking Olivers here but I have COOPs with gas Budas. The 230's rated load speed is 1650 and High idle is 1850. However I have a copy of an old Buda factory manual with a table of torque and HP. Torque peaks at 1000 but HP is rated up to 72 at 3000. The old industrial engines were used in lots of different applications. Run at the rated speed as long as your high idle is set properly.
 
Thanks everyone for the input. Me and dad have decided we're just going to run around 1800-2000, because our 1855's 310 has 4500 hours that I think are original. So I don't want to blow it up. But we have a cummins 5.9 to put in,time and money don't allow, this year :( But our 1365 is a good dinner so ill run it at rated speed.
 
The 1800 I ran at PTO speed on the tach. Had to run it that fast for the hydraulic to work right. The 200 AC I traded for does not have to be run that fast, it seems that develops its power at a lower RPM.
 
My dad surely read the same book. He turned up our E4 co-ops up to 2400. In all the years never had a gas engine give any problem.
 
It could have been for your personal safety or because the job required a low speed. For heavy work I would run at full rated engine speed now.
 
Different tractor but the idea is the same had a d 15 Allis on pto equipment always ran at higher idle but if in slippery conditions always idled down as it would spin out quickly at higher idle. The oliver is also that way run at pto speed but if get into conditions where the tractor would spin or over speed the engine like going down hill with full load I keep it idled back.
 
Our 1650 was purchased new. With 2 kids running it, dad kept yelling at us for running it at full throttle. When he was at the dealer one time, he told them we were destroying it. Shop foreman showed dad the owners manual where it said open it up depending on load. After that, he left us alone. It was never apart until a pin bushing turned and made a new oil drain hole. That was with over 7,000 hours.

Another tractor I sold a few years back was ran a little different. Dad would have flipped out if I ran his tractor like this but he did watch me run mine a few times. Tighten the chain, bring up the engine speed until boost comes up, ease out the clutch until it starts rolling, and open it all the way. Most of the time, it ran at 2900 under load. And it never exploded.
 
You can't pull a three bottom plow with an 1855 in third gear???? What the heck kinda ground you got and how deep are you plowing???? Have you had that motor on a dyno lately?
 
you can load the mule pretty good with 3 16 or 18's I have seen the front of the 1850 stand straight in the air with 3 16's never stopped but belched a little flame and kept rolling
