bolts vs rivets for sickle mower

[jlbash1]

So I have never used bolts on a sickle mower, but think it would be nice. Do they make special bolts for this application? I would think they would have to be made of soft material so the bolts would give instead of breaking something else.

Thanks

The bolts are a bit special, they have a thickened portion where they go through the bar then thin again where the knife attaches.

BTW they are an absolute dream to use after rivits.

If you're not a regular sickle re-builder, rivets can drive you bonkers. But if you've done enough of them, they get easier with each re-sectioning.

I use an anvil to remove the old ones. (Put the bar against the top of the anvil with the section hanging down on the side. Smack the section with a HEAVY hammer. That shears the rivets. Use the same anvil and the same hammer to re-clinch the new rivets. With practice, a person can do a 7' bar in about an hour.

Bolts are easy. They are nice when you need to repace a section in the field too. But they AREN'T cheap compared to the rivets.

(I still prefer rivets.)

Hi Jarrod,
Quite often sicklemowers have a ratcheting clutch assembly in case you run into something you shouldnt have /forums/images/graemlins/grin.gif

Doing an internet search for these hasn't yeilded much. Now of any good sources, or is this something I can pick up at any tractor dealer?

I have the same project going on. Though it's a very low priority. Saw these on eBay.

One thing that might be mentioned here-sometimes the heads of the bolts stick up enough that you have to replace the hold downs and Guards to clear them-

A few years ago I converted a NH sicklebar mower (51?) from rivet to bolt on knives. Never looked back. Had to replace all the hold downs, but NH actually had a kit to do that. All parts available at NH dealer.

I did the same last year for a old NH mower condtioner. Again all parts available at the NH dealer.

I've been riveting sections for 40 years and agree that it gets easier with practice. On thing that really speeds thing up is a riveting block and a properly sized rivet set. I have an old John Deere riveting block that I picked up at a farm sale 25 years ago It has a channel to hold the sickle "backbone" with two hardened cups to hold the rivet heads. You just slip two rivets through the backbone and lay it on the block, drop a section over the rivets and use the rivet set and a hammer to form two perfectly rounded rivet heads. I set it in the middle of a 16 foot workbench with blocks to both sides to support the remainder of the knife. One important thing is to clean the part of the backbone of any rust before putting on a new sickle. The advantage of rivets over bolts are:
1. they can't vibrate loose.
2. the rivet swells to fill the entire hole in the backbone
3. no modification of the cutter bar are needed.

The John Deere block also holds guards for riveting in new plates and has appropriate holes for punching out old rivets. It's extremely well thought out. I don't know if they still sell them but I wouldn't sell mine for a couple of hundred bucks. It really speeds up what can be a difficult job and almost makes it fun.

If you're not a regular sickle re-builder, rivets can drive you bonkers. But if you've done enough of them, they get easier with each re-sectioning.
