New keepers for shanks on box blade

mdhughes · Jan 29, 2017

The keepers that come on the Land Pride box blade are a pain to get out when you are trying to do work with and move the shanks up and down. I saw these on eBay and thought I would give them a try. They call them F-pins and were $26.74 with shipping for five of them. Seem to work so far, I will follow up when I get a chance to try them our for real.

Here are a couple pictures to compare what comes on the box blade and what the F-pins look like:

And a picture of the F-pin installed:

How does that keep the scaifer from moveing up or down.??

That's a clever idea. I will keep watch to see how good they work

I think if fills the gap up so the tooth cannot come forward and unhook. It looks like it just hangs in the slot loose

Scarifiers are notched, f-pins keep them engaged. I have the same setup with those spring clips on my Gannon box blade. Kind of a pain, especially when one "boings" out of the channel locks & goes flying. I had some "L" bolts (for stem wall to sole plate) and cut the threaded portion off, for the same effect as the "F" pins. (but cheaper

)

For a nwb that hasn't used one yet, what would keep the new F pin from bouncing or rattling out on its own? I noticed a hole in the pin but nothing to keep it in place.
I'm obviously missing something

When the shanks are are down, there will be pressure on the pins and I hope the length of the pins will keep them from bouncing out.

That is my experience, haven't had a single one pop out yet. When I'm not using the rippers, I reverse them so they're sticking up, and drop the "L" pins in. Haven't had any come out that way either.

Now that I've figured out what I'm looking at, I have to say I like the keepers on my Woods HD box blade better. 1 piece locks in both shanks on each side and has a spring link pin keeper.

I hate those Land Pride spring clips--they're surprisingly difficult to get a good grip on with channel locks--and these look like a great alternative. Price doesn't seem totally out of line, but I'm wondering if I might hack something cheaper and save some money. E.g., dropping a hex head bolt in the slot, with one side of the hex cut (or ground) flush with bolt shaft. Must ponder.

Been looking online at box blades. Looking at the Land Pride version it appears the new models have done away with those keepers. Am I seeing it correctly? Looks like they use a pin through the scarifier and hairpin clip instead of a clip on at least the BB15 model.

How do you like the BB2560? Would you buy it again? Do you have any experience with other brands to compare with?

Just to follow up on my post, I really like these keepers better than the ones that came with the box blade. It is so much easier to move the shanks up and down. I used the box blade the other day and didn't have any problems with the new keepers. I would recommend changing to this stye keeper.

hiho silver, some of the Land Pride box blades have the pins that go through the shanks and some have the keepers.

At $5 each, one would think that they could be fabbed up at far less cost.

Some bar stock and a torch for bending (since the hole doesn't seem to have a purpose).

Or a hack saw (plasma cutter) and a welder for something a bit fancier.

OTOH, $26 for a one time expense isn't too bad - especially if it relieves some stress.

They probably put the hole in there in case you want to rig up a keeper chain.

I use 3/4 inch re-bar, heated and bent to shape. I haven't had any pop out yet. The rough texture also helps keep 'em in place, me thinks.

I have the BB1548, and it uses the pin with the hairpin clip to lock the scarifers in place. I love it! It is easy and quick to change. No tools needed.

Sorry to resurrect this one, but I have acquired an identical ripper, all I have is the shanks and the tool bar that they go into - no pins or keepers.

I cannot for the life of me understand how those keepers actually retain the shank though?

In the third picture is the f pin driven in and held by friction, or is it just hanging there?

Alfred_2345 · Mar 18, 2024

The scarifier has notches that engage in the box blade. The pin/keeper then goes into the space left by sliding the scarifier notches into the support. In the picture below, the scarifer would move to the left and the pin would drop into the open space on the right.
