Nuts up or down

[Matt L]

Nuts on the top without fail. Much easier to work on during harvest.

 

[Dead Rabbits]

They did, and this one is, hence I planned the change when replacing all the sections ready for harvest as the Class nut n bolt system is far superior...............if the nuts are on the top

I’m with you. Nuts on top. Then when you need to change a section you just take the nuts off and change it. No pounding bolts out or taking guards off.

Rather than just asking for the sections to be replaced why did you want the nuts on top? If there is a good reason then explain it to your employee. If it is just because it looks right then should not matter.
I drove combines in very rocky ground and do not remember changing many sections but they were all riveted

Nuts on top definitely on the knife but everything else I do is bolt on top .

Black fen land here and silt on the other farm, when crops go flat they seem lower than the ground. I've set up the reel scratch the ground to lift before the knife, but this means if its pulled in it will hit the knife, so occasionally loose the odd section with brain fade during a long day. The Class bolt is designed to be squashed into the back of the knife and make a press type fit, the sections then secure with a nut from the top, then when you need to change one, its an 11mm socket, 2 nuts off, section swap and 2 nuts back on. If it was just for looks, I wouldn't care, but its time efficient and as the system was designed to be worked, that's the issue..............................and how many of us have time to waste during harvest ?

Thanks for that. If the bolts are made to fit that way then he will have to redo them

I don't think the knife will slid in with the nuts under as the bolts will catch on the fingers. When I changed the Claas 108 from riveted to bolts I changed the knife keeps to get a higher bridge for the nut and bolt to slide under.

Precisely. This is how the NH system is.

Would be even quicker if you'd gone with NH system.....10mm socket!

 

[Matt77]

it has to be nuts up on my claas, doesn’t fit if you try other way.

 

[Lincsman]

The whole idea of nuts and bolts is so you can replace a section with it in situ, so nuts have to be on top as the bolts are "captive.. on a NH anyway.

 

[Bernardbean]

Nuts on top of our Massey's, don't think they'll fit other way around, can you get somebody to video you attempting to fit that knife, might make quite a few of us smile ......

 

[icanshootwell]

Is that fresh paint?

prefer the bare metal look too.

 

[rob h]

On my Mf 32 only fit with the nuts on top not enough clearance the outher way.yours might be ok being a newer machine.

I always use rivets when doing a whole knife .but use bolts for in field repairs

 

[czechmate]

You haven't seen it in the flesh, the knife back is now twisted and bent, looks like it will be take all the fingers off to put the knife in as its so distorted there's no way it will slide in imho.

I'm not looking for a fight, but bear in mind, I'll be the one getting covered in dust changing it while he sits in the air con tractor. Its easy and clean to pop off to nuts on top opposed to punching 2 bolts out from underneath i would have thought

Better than rivets

 

[lostdog]

Over the years I've driven several makes of combine; gleaner, case, jd, mf, claas and nh. Nearly all had nut and bolt knives and all of them were nut up. As said it means you can change the section and refuse bolt so no need to take bolt out which saves time. Also slightly easier to punch the bolt head out if it has sheared.

Our obsession with rivets is not shared in the US, NZ or Australia.

Why?? how can a rivet be better?
