    MMM arms dropping on 1026R

    Just wondering if other 1026R owners are experiencing the MMM hydraulic arms dropping down (when mower is not on). On mine, have to keep raising them back up, every couple hours or so. Have the SCV locked, so am not accidentally lowering the arms.... apparently have slow hydraulic bypass, seep or some such?

    I am not sure on the new machine's, but with the independant lift on the 2x20 series it is quite normal. Is there a knob/selector that you can lock them up with?

    2305 is exactly the same way. Use the rate of drop valve fully closed to lock the lift arms in the up position.

    Just looked at my 1026R, it has not been started today and the arms are down. I'm not sure and I will try it myself, but seems you could raise the arms and then put the deck hight adjustment in the lock mode and that should stop that.

    yup, those lift cylinders are not made for "keeping up" or holding up anything, they are strictly for lifting and lowering

    I just, ths evening, recalled there is that lock position on the deck height adjustment... so, I suspect you are on-target here... that this will work. Thanks!

    That will help only if you are using the mechanical lift of the arms to raise and lower the deck, the independant lift removes the deck from this equation. And here is what will happen. The deck and arms will settle to the lock up position. The weight of the arms will now still want to continue their descent (due to their own weight) and will unless you lock it by closing the rate control knob. Here is an extract from the manual.

    Thanks for this tip! I totally missed this while reading through the manual. Although it sounds like an unnecessary pain, I'll try it tomorrow. So, first raise the deck fully, put mower height adjustment in Lock position, then rotate Rate of Drop control fully clockwise and deck should truly lock in the upright position. Right?

    Another question. In another thread it was mentioned that the dummy plug on the lower dash was for an Independent Mower Control Switch. Does Deere have any plans to actually make this available? What advantage would this switch have?

    Will lock the 3-point for sure.... that lever in the picture is for the 3-point....
    not the mower....and the rate of drop control is for the 3-point, as I understand it.

    I just lock the mower adjustment .... arms seem to stay up fine.

    If you have the mechanical lift only this will work. You do not need to use the mower height knob.

    If you have the independent lift the mower control height in the the full lockup position is only way to hold the deck up. Note that the deck will drop slightly with this arrangement.

    Sorry, I am unframiliar with this option. It just doesn't make sense with the mechanics of these lifts. Are your referring to the cruise control switch?
