72" Piranha Tooth Bar Install and Review!

[Poopdeck Pappy]

As an old mechanic, I bolted mine in from the outside because the outside takes the abuse. I haven't used my bucket very much, but I did make a video.

I did the same thing but mainly because I didn't want to be banging my knee or ankle on that exposed nut and bolt sticking out there.

If you post some pics of your problem I'll offer some solution on how to fix. (0:

PapaPerk: My property and tractor are a couple of hours away. I don't have any pics to post and probably won't be back there until after Christmas. My issue is similar to yours (see last picture in your original post) except that my mounting hole is even closer to to the reinforcement bar than yours. I tried drilling the hole with a step drill bit, but the bit would catch and about break my arm when it contacted the raised bar. Not fun.

Raised on a Deere: I may resort to your solution of just bolting it on crooked (maybe with a 1/2" bolt). Beauty is not the goal, just utility.

Eric the Oracle: You had way too much fun making that video. I can't wait until I can use my PTB and have fun as well.

TN, when you do get around to using it you'll love it. I'm planning on getting a 6 footer for my Ford 3930 as well. This way I can have double the fun looking for the pots of gold.

I haven't advocated more about any aftermarket product than the PTB. In fact I started two threads dedicated to the PTB because it has just been fantastic.

You have a few option. Use a cut off wheel in a grinder and trim back the reinforcement, use a Allen head cap screw that has a smaller diameter head than a hex head, make a clearance hole using a hole saw (use longer center drill to support then let hole saw cut a nice radius into bar. Trim cut out with cutoff wheel resulting in a half circle in reinforcement.

Last option is to extend the support bar on the tooth bar.

For what it is worth, I simply used an Ivan multi-hole bit on my 14.4 Panasonic drill and free-handed the holes after indexing with a center punch. Maybe a minute to drill each hole using an oil can. Since the tooth bar's holes are slotted, for an epic tight fit over another bolt-on bar, I first mounted the piranha bar, then forced the bucket down on its edge picking up the front wheels, and then tightened up the hardware. Seems to me, I used self-locking nuts.

Yes but he needs to cut through the bucket reinforcement. Step drill will have trouble with this. He basically needs a half hole counterbore in the reinforcement.

Took me awhile to get a pic of my piranha bolt on my Kioti CK27:


Drilled from inside. Could not use step bit. Mine was far enough inside the reinforcement that, although the bolt shows, it did not cant when installed.

edit to add: had to buy longer bolts, of course. as long as buying new bolts, went to grade 8.

If you read my post (#99) I had the same problem drilling the reinforcement, used several cobalt drill bits starting at 1/8 and going up to 1/2, plenty of oil and the "drill press".
The slot should be long enough so you can get entirely within the reinforcement for a flat mount.
