Changing boxblade scarifier teeth

AlanB · Mar 29, 2006

Time to change the teeth on the end of the boxblade scarifiers. The old ones are peened on and I thought I could just knock them straight off. Once again, I was wrong.

Next thought is the plasma and open one side, but thought I would ask in case I was missing something obvious. Could be I just want to play with the plasma.

The other posts on this subject seemed to have wandered off topic.

Any quick and easy tips to get them off?

Any quick and easy tips on peening on the new ones?

I was thinking plasma off and press the peen in?

Open for suggestions on better ways though.

1/2" drill bit smack in the middle of the peened indention.

Heat with torch 'till cherry red, then peen with a punch.

Just did 3 on my Woods box.

I just smashed a chisel down the side of the shank wedging it between the peened part of the tooth (both sides) then knocked the tooth off.
Tapped on the new tooth on and smashed the dimples back into the shank.
Clamped the shanks in a vise while doing this.

Funny, I have a hard time keeping them on. Seem to be able to find them though when they get ripped off. I now weld them on. Is it worth the hassle to change the wear tips? New rippers including the teeth tips are only like 15$.

That's a good point Highbeam,
Usually the flat part of the tooth breaks off. I don't see why they couldn't be used in that condition? Just lower them one more notch if you get the long ones....Or just weld on another flat part on the tooth.

Some types of ripper teeth are cheaper than others. I used to have a "Lowery MFG." box that used the same teeth as what TSC sells. They were cheap. Break a tooth, chuck the entire shank in the scrap pile and replace it with new. The shanks for my Woods box are different and not quite so inexpensive. Add to that, local Woods dealer is ALWAYS out of the shanks, but has the teeth. (And the teeth are easier to store in the trucks toolbox. I can replace one in the field if I need to)

It was worth it too me, mine were worn to "nubs", the replacement points were $2.75 ea. I drilled the first one out to 1/2" and beat on it till it came off. The other two I just grabbed the plasma and hacked off both sides and tapped with a hammer and they fell off.

When I put them back on I used a 1/4" nut to push the metal down into the indention with the press.

Was it worth it? From my point of veiw I did not need to lay out $50 to $60, It was only about $9 plus about an hours time fooling with them. I know the quality of shanks I have (good enough to wear the teeth off without bending) and I got to play with the plasma a bit and use the new 20 ton air jack in the press and mash some crap.......... /forums/images/graemlins/grin.gif

If Hanna had a job waiting on that boxblade to get done, I would have bought new points, (or actually just used it another time tilted more than I should.)
