  • Weight limit on the hydraulic lift of a "50 8N
  • I'm looking to purchase an 8N and was wondering if you could tell me what the maximum lift weight on the hydraulic lift would be? I have a rototlller that weighs 630lbs and want to make sure it will lift it.

    Thanks so much!

  • The N Series Fords were marvelous little plowing and discing tractors that would pull more plow than any other brand of tractor in their horsepower class. They also disced very well.
    But they suck as a rototilling tractor unless you install the somewhat rare and expensive Howard transmission in them.
    If you are dead set on a rototiller for your project I would skip the Ns and look at a much newer tractor with suitable ground speed.
    If you are wanting a Ford tractor I suggest one that is 1965 or newer as they have more gears and slower speeds.
    By the way, plowing and discing is easily learned and a Lot of fun.
    Running a tiller is about the most boring thing you will ever do with a tractor.

  • Factory spec and 70 year old machine ability MAY be two very different abilities. It will depend on condition of hydraulics.
    As for the rototiller. In the 1950s my father acquired a 3 point rototiller in an auction. As said, and for our '51 8N, the standard 8N gear ratios ground speed is/was too fast.
    Now, last year I was suprised when my neighbor said that his son purchased a new rototiller from TSC and was mounting it on their 1953 NAA (Jubilee). I said then that the ground speed was too fast just like an 8N.
    WELL, was I shocked when I saw him working his garden plot. 1st gear, no problem. Very fluffy finish. Then, double shock, he went to 2nd gear. Dirt was flying!
    I have not investigated the make but obviously the mfg. engineering took Ns into consideration.
    BTW, our soils here are predominently clay. I will say that he has plowed this same parcel in past years.

  • I've never had a problem with the rototiller on my '54 NAA, but it has a Sherman auxiliary transmission. The 8N I'm looking at has a Hupp auxiliary, so I'm hoping that will serve.

  • Both the Sherman and hupp slow the tractor down but they also slow the pto down at the same time. A Howard gear box was made to run a rototiller, as it slows the tractor down without slowing the PTO. If the ground is fairly soft you may get away with it.
    Good Luck

  • Re: Weight limit on the hydraulic lift of a "50 8N
  • This has been debated at great length but one thing is clear - actual individual experiences will and do vary depending on the soil conditions and design of the tiller. Here is one OEM data point as food for thought.

    The Operators Manual for Bush Hog tillers which have a tine speed of 238 RPM @ 540 PTO RPM says the following:

    Ground speed for operating will depend upon the type of cultivation. Recommended speed for efficient implement performance is between 2 and 5 mph.

    At 1500 engine RPM (540 PTO RPM) the ground speed of an 8N in first gear is 2.8 MPH.

  • Re: Weight limit on the hydraulic lift of a "50 8N
  • First let me say 8N's are generally regarded as being geared too high for roto-tilling. That said the load limit is usually quoted at roughly 1000# at the lift pins. You are probably OK but but much depends on the lever arm of the rototiller hookup. The closer you get that 630# to the lift pins the better your chances. And you probably want some front counter-weight.

  • It may lift it, but normally a 8n's ground speed is too fast to properly operate a rototiller.
