    hyd version that ran of fthe nose of the tach drive was available for the naa, and a manual version for the N series.

    660 was the first ford with a true 2 stage clutch.

    Just realized it was probably the '58 841 we had that had the two-stage. Been too long since I was on either one...

    Negative on that one as well.. the '4' in the 841 denotes a 4 spd trans.. single stage clutch.

    a middle digit of '6' denotes a 2 stage clutch.. and on the later XX1 models.. a middle digit of 7/8 is the independent pto model

    The short answer is no.

    Sorta assumed that might be the case. I'm a complete tractor rookie but have some friends involved in machining and hydraulics so any info is greatly appreciated

    And the long answer is YES. Just change the transmission from the Jub's 4 speed to a later model x50, x60, x51 or x61 transmission. You will probably need the differential too as the brake cross over was different in different years.

    The "change is more of a fairly large swap of parts, but if you keep the fenders and paint correctly it will be very "jub-esque". A big PLUS is the later tractors have a much stronger rear end (Jub was known to bust pinion supports).

    Add the correct hydraulic manifold to the required component list. The short answer is still no, but it doesn't surprise me that someone had to come along and point out the theoretical inaccuracy of the practical answer.
    By the way, an x50 or x51 transmission housing won't provide the means to provide live PTO or a double clutch, and installing a transmission housing with a later model and serial number stamped in it makes the tractor a 661 or whatever with an NAA engine and fenders.

    I agree.. swapping the back half of an *60 or *61 is really just an engine transplant. ya might get a beefier rear axle if the donor was an 860 or 861.. but it's alot of work. better to just start with the correct tractor model needed..
