Transmission lube

Didn't want to hijack the post below. My
question is on a 1650 and 1850 during
stationary pto operation does it matter what
neutral range the transmission is in to lube
properly? I've never given it any thought
before, just curious if it matters.
 
Hmmm,never gave it a thought either,but my 1850 sits running the grinder mixer most of the time.
 
   The counter shaft is powered by the input shaft, thus the high "N" position will give the pump more RPM.   This pump does not produce much volume of oil, thus the pressure is not very high, just needs to keep oil at all the lube points.
 
which neutral? Isn't neutral, neutral? I don't think neutral has a range either. On my 1850 the tack gives a pto setting and I must say the rpm it gives is higher than any rpm I've ever run it at. I think it's 2500.

The neutral on my 1850 is in the center of the shift. The top is lower gears, the bottom higher gears with each having a reverse. Neutral connects both and seems to me, neutral for both.

Any operation of an attached pto equipment is greatly effected by the rpm and the closer to the designated rpm the more efficient they run. I've run fine at 1600-2000.

I'll admit, the question confuses me.
 
Thank you Mr Star. Both these tractors have been used to operate a forage blower since being on this farm. Sounds to me the high neutral position would be better.
 
I've always just left it up in the top neutral so the shift is out of the way more for getting off and on. I guess that would be the high speed neutral wouldn't it? Maybe it's made that way on purpose.
 
I almost always have the shifters in the pattern that has the R2 gear for both the 1850 and 1650. The 1650 would be ok, I'll just need to remember on the 1850 to bump the shifter into the upper neutral.
 
When the shaft seizes it is to the low range gear, thus I always leave it sitting stationary on low range, also easier to get on and off that way!
 
Maybe I'm missing something but neutral is neutral. How can rpm be any different in any neutral. If there is a change it isn't in neutral. Neutral is free wheeling. If free wheeling has a range it isn't free wheeling.

The opposite of neutral is in gear and gears have ranges. Does anyone have a 1 and 2 neutral? I have a 1 and 2 reverse.
 
I am going to argue the opposite. When the transmission is in the high neutral, the low range imput gear is turning much faster than engine speed.I always told farmers to run the transmission in low range, granted the pump does not pump as much flow but you don't need as much. When ever there was a failure on the top shaft it was always the low range gear. More details later.
 
Gary, in your 1850 all the gears turn anytime the engine is running. There are 2 gears on the top shaft. A collar connects the gear with the imput shaft. One gear is used to connect the gears that are in the high range the other one the gears in the low range, therefore the term high range neutral and low range neutral.
 
They are taking about 2 different items here. You also have a spur gear transmission in the Cockshutt, not a constant mesh unit.
 
Ok, same situation operating a stationary pto implement (forage blower). The 1850 has hydraul shift the 1650 has hydra power. Not trying to make things more confusing, but what position is best for those to be in during stationary pto opertion? Maybe the difference is so little that it really doesn't matter?
 
Kevin: To me it makes sense to have over under in low range and the transmission in low range as well so gears are not turning at their maximum speed? Are you doing this in a flat area? Remember there is another check plug to check the oil level when you are on an incline on an 1850.
 
Yes the area by the silos is flat. Was not aware of the second check plug for inclined areas???
Thanks for the answers.
 
so neutral is specific to the drive gears and not the pto, the pto is always in gear, just engaged or dis engaged. That makes sense given the pto continues to operate while the tractor is in neutral or clutch depressed.

So the pto will operate at different speeds depending on the neutral range the the drive gears are in? I thought that was controlled by rpm? It would seem fluid flow is controlled by rpm and the reason the tack has a pto setting. If fluid flow is the reason the tack has a setting them operating at the tack setting is important to proper lubrication of the pto, not just proper operation of the attachment.

I probably should increase the rpm's to the prescribed setting then.
 
You have part of paragraph 2 way wrong. You have a phone number? I will call you and explain it. Unless you have one of the new area codes for cell phones your area code is probably same as mine unless you are in the state up North so you don't need to post it, J.
