  • Hello,
    Hello all,

    First time back in years. Glad you are still here.

    I just got involved with helping my son sort out a 9N. I had an 8N years ago and was often accessing this group of experts to keep it going. Anyway, I don't recall if the PTO needs to be engaged in order for the 3/pt to lift? On this tractor it only raises if the PTO is engaged and thus the mower is spinning. Also I have a question about why the 3 pt won't stay up.....falls immedately after PTO is disengaged or the engine is shut off.

    Thanks in advance.

  • I just had the same problem with my 9N. Immediately after shutting off the engine, the disc would drift down rather quickly. Someone else had the same problem and it was suggested that the pressure relief valve was at fault for the drop.
    I purchased the replacement valve and installed it.
    For me it was easier to drain the system, all three drains, pull the pto shaft and the left side access that contains the pto engagement lever.
    When I was done, no more drift down. It hung there for an hour. Good enough for me.

    OK - as Bruce said, yes the PTO lever must be engaged in order for the 3-PT to work. The 'live' PTO was a few years away when the 9N was born. A properly tuned hydraulic system will sustain a full load UP for weeks, months when the tractor off or PTO disengaged. Dropping the load minutes or a day or two after shut down is the big clue that the cylinder is worn and it and possibly the pump needs to be pulled, inspected, and rebuilt. Here is a document from our HOW-TO's to get some info but be aware this is for the 8N system which is a different pump and lift system. The 9N/2N uses only DRAFT CONTROL and there is a 'wishbone' bracket that connects the top cover and cylinder linkage to the pump. It must be removed before the top cover gets removed. The top cover on both has the cylinder bolted by four bolts located under the seat. It is important to leave these fastened until you have top cover on your bench. The I&T FO-4 manual and the MPC and OEM Owner's manuals are big tools to help in R&R's the system. As you know, you can get a complete gasket kit from Just8Ns or Dennis Carpenter as well as the new cylinder, NAA piston, and backup wiper. I strongly advise to not waste time trying to hone or rebore the cylinder. If the piston is still using the OEM 3-ring type, get rid of it and buy the NAA-530 one with rubber O-Ring.

  • Scappose? is that over near Papoose?
    I heard tell the sun goes down at about 3 PM when it drops over the west ridge.
    I suppose it could be worse.
    You could live at the other end of the Scappose-Vernonia highway.
    Catch you later.

  • Yea, the PTO needs to be engaged for the lift to work.

    Re the lift dropping, see tip # 16; post back w/ what you observe.

    Got the manuals? See tip # 39

  • Thank you Bruce.
  • I will perform those inspections next time I see the tractor. I will post back the results. Thank you
