the old 9N

[Caroline Chamblin]

Hi Folks,
Can someone explain why it is easier to shift the transmission when the PTO is not engaged? Sometimes I take the PTO out of gear to be able to shift then re-engage it to mow. This is mostly switching between reverse and first gear. I still don't have the carb exactly right but it is mowing. The ammeter still goes to negative voltage after turning off, at least until I tap the cut-off switch with the screwdriver handle. 6 volt system with round can distributor modification.
thanks,
Caroline

ou must not have a good working over-run coupler. That would mean your PTO driven implement (bush hog?) has its inertia to keep spining your PTO & thus turning your transmission even though you push in the clutch. If you leave tractor & PTO in gear & de-clutch, it will keep pushing your tractor forward almost as if you didn't de-clutch.

I agree with jmor.. that 9n has a tranny driven pto.. that means a spinning load on the pto can keep the tranny spinning.. an ORC will help this.. hit clutch, hit brakes and come to a stop, then tranny will be calm, then shift out and in, and then let off clutch and go .

as for the sticky cutout.. get a new one.. before you forget and smoke some wires.

JMOR.......Caroline has a 3-spindle finishing mower on 4-wheels. It doesn't need an ORC.......Dell

Caroline........I thought you replaced yer 2-terminal roundcan cut-out about 1-month ago? Did you remember to "polarize" it like I taught you? ......Dell

 

[Caroline Chamblin]

Dell, I did polarize like 5 times each time I run the tractor. I shouldn't have to each time right? And yes I have a finish mower. sorry I didn't mention that. However I may get an orc just because of this difficulty in shifting when PTO is engaged. Or just always take it out, shift the transmission, and then renegage the PTO. Tractor does seem weak on power with mowing short grass in 1st gear at almost full throttle.
thanks everyone!

orry, Dell........didn't mean to get between you and dinner! :wink:

Caroline.......not enuff power in first? seems to me you had yer carb professionally rebuilt last month. Your carb down-pointing mainjet might need to be enriched 1/4-turn CCW. Mainjet works at WOT (wide open throttle) Leave yer side-pointing idlemix alone, it only works at 1/4-throttle. ......Dell

 

[Caroline Chamblin]

Yes the carb was professionally rebuilt by ME! So who knows if it is right! I have followed the adjustment directions posted on this forum. You can repost them if you like and I will do it again and repolarize!

at least it does run

I have a john deere crawler that had a cutout relay. I replaced it with a switch and it works just fine, just have to remmber to turn it on and off. Sounds like your is just sticking, long as you remember to wap it when you shut down. When it don't charge anymore you will need to do something with it. I would not waste my time by trying to repolarize the genny. If it is charging it is good>

Caroline........yer down-pointing mainjet should be 2-turns CCW. Iff'n 2-turns and you don't have enuff power, do additional 1/4-turn CCW for more power. .......Dell
