Bolts for replacing sickle sections

Do you need a special bolt to convert a sickle section from rivets to bolts? I know they need to be the right length so as not to hit anything but are people just using regular round head machine screws? Do you need to put loc-tite on the nuts so they don't shake loose? I have a JD #9w mower and want to use nuts and bolts now. Do they make different hold downs for the cutter bar to allow for more clearance for the bolt?

Thanx,

Jerry

These sickle bolts are a special bolt made just for this purpose. They have a serrated shank on them so the will fit tight in the bar and stay put when replacing the sections. They can be purchased for the normal sections and also longer to use attaching head or sickle drive. Most implement dealers or farm supply stores will have carry these. I never use lock tight or any thing on them and they may be of a self locking type.

The bolts have my vote! I banged on too many rivets. When bolts appeared, I gave them a try, with reservations, of course. I would never go back to rivets, and I don't know why anyone in his right mind would!
When it comes to cost, initial installation is higher. But when I have to replace a bolted section, the most hardware I have to replace is the locknuts. Once bolts are installed, the only tool you need is a 7/16 wrench.

As a custom hay operator here in north central Texas I can tell ya this for certain!! There is no way in the world I would beat on rivets(been there done that) as opposed to the ease of using bolts. If anyone tells ya its easier using rivets they have swung that hammer too many times. It does cost more to replace bolts but its so much easier, also you don't have to remover the sickle to do it if you don't have one of those fancy rivet tools which run around $50 to $60 bucks. I will, when I get a new sickle, buy one riveted and then as sections have to be replaced I go back with bolts, this saves some money. I have rebuilt many sickles as Im sure many on here have as well and its a job!!! Why make it more difficult than it has to be, go with bolts you will not be dissapointed.

We used theas bolts for several years and they save more than the added cost in time alone.Plus you lose a lot less skin off your hands I belive you can get bolts from your dealer that will require no modifications

good luck Grinmi

Once ya catch on to using the rivets ( and learn the correct procedure), rivets are the fastest way to install and remove the sections...!!! A nice piece of steel, a ballpeen hammer, and a coal-chisel are all ya need....well--maybe a punch, too..!!!

Can we agree to disagree???? Used the method you described; moved up to Johnson Sickle Servicer; had the hand held device letting you replace individual sections while still in the machine. Finally swapped everything over to the bolts; can't imagine anyone who has ever used the bolts would go back to rivets under any circumstances.

You might be right on a sickle mower like this, but _not_ on a mower-conditioner!!!! No room to swing a hammer. Combines as well, simpler to go with the bolts on a combine.

He'll need the special bolts, you can find them at farm supply stores by the mower parts, or from a dealer - most any dealer.

There are higher clearance hold-downs if you need them, again at the farm supply or most dealers.

You can also check out mail order, such as Shoup.

You might have to change the knife back as well as I hear the bolts are a different size than the rivets, I would stick with the rivets, not that many problems and a lot cheaper

I have yet to see an application where the knifebar would not accept EZ-bolts. Except where some holes are worn oval, then it is junk anyway.

Special bolt with mini-splines (there's a word for this, but can't recall what it is) to help keep bolt from rotating. Lock nuts, so no loc-tite is needed.

They do make high clearance hold downs for bolts. I don't know if they are available for your mower.
