    So, what’s the collective TFF view on this one.
    Already had a brief exchange of views, but don’t want to upset a partnership, but as the combine driver and co owner I think I should have final say.
    So here we go

    This is my preferred way of using the nut n bolt way of securing knife sections.

    Arrived at the combine yesterday to be greeted by this.

    Wasn’t impressed as I’d left instructions on how I’d wanted it done.

    So before I show my frustration Monday, who’s right ?

    If I did it I'd have the nuts underneath but does it make any difference? I wouldn't want to fall out with someone about it.

  3. Always used to have them bolt facing down but with nylock nuts?

    my understanding it bolt in from top where possibly then if nut drops off theres a chance you could spot the lose bolt before losing blade, could be wrong though, i would have gone bolt in top regardless.

    If there is plenty of clearance underneath for the nut then "nut down" would be less likely to catch on the straw etc. I take it that the bolt head is slightly smaller than the nut.
    Are those nuts the sort that are slightly squeezed and grip the thread like a nylok.

    Nuts down. (Edit - on fingers)
    Edit - Nuts up on sections.
    Looks like you're doing them yourself from now on.

    Nuts on top for me then if you change the section again the same bolts do another time

    Pretty sure our NH would only take the nuts on top.

    That's how I've been used to them and never had an issue.


    HOWEVER....what surprised me when I first saw the photo was the nuts on the knife keepers being on the top! Mine have always been fitted bolt down from top.

    Surprised nobody on here has passed comment yet given they are all "nut down" advocates.

    Always assume the bolt will be seized so nuts on top so best chance of getting socket on to crack the nut. If nut worn so cannot get a socket on then easy to grind off with universal spanner and punch through.

    One thing I have learnt since my 2 sons have come home is, is my way the right and only way.

    Before questioning why something has been done differently to the way I have always done it I ask myself a few questions: Will it work like that - Is it really wrong - Does it matter - Is it worth an argument about it - Do I want to discourage their progressive thinking.

    Believe it or not, I'm very proud to say that we never have a cross word and it is a pleasure to work alongside them

    So my advice is, does it really matter which way the bl00dy bolts face. The guy looks to have done a very tidy job and a pat on the back and a word of grateful thanks should be the Monday morning brief.

    Nuts on top here too, handy for changing a broken section as same nuts and bolts do without having to even remove bolts, and bolts can’t drop out as there’re squeezed. Would imagine it would be more awkward changing a section with the bolt underneath. Never had an issue with them catching crop.

    That’s why I like them that way, saves a lot of work changing in the field and 3 times quicker.
    Doing it nuts down you have to replace bolts every time as the Class ones are squeeze to fit, had them work loose if reused and that then elongates the hole in the knife.

    Exactly where if you squeeze them into the knife they stay put

    Yes, typical standard for them I’m afraid, it’s ok if it looks pretty. Now have Class green on a MF combine

    New Holland knife nuts on top
    Fingers nuts underneath never known any different
    On new Holland you would have to knock the bolts out as there’s small splines on the bolts

    It has to be nuts up on a massey as the bolt is spined to fit in the knife bar and has a "thin " bolt head
