72" Piranha Tooth Bar Install and Review!

[square1]

What do you mean by 6'? is that the diameter above ground? If so your area has some big trees.

Oops, 6"..heh...heh...

 

[Egbert]

Has anyone devised a quick-mount for the piranha bar?

Instead of bolts, would a pin hold the bar in place?

The ease of the install depends on if you get things which fit easy or not. PapaPerk didn't have to drill thru the reinforcement. I did. Lot more time spent drilling.
Note to potential buyers - give Harry the dimensions of how far back your bucket is reinforced and he can probably make the "ears" a little longer so you DON'T have to drill thru the reinforcements.
PapaPerk didn't use a washer and put the bolt head on the outside.

I put the bolt head on the inside and used washers on the outside.

Please don't start an implement war. There are several threads here praising the RR and I think some users never take them off. But they are a different tool. It's like comparing a rotary brush cutter with a scythe.

Also per 1 comment - tooth bars are PROBABLY better for pure digging, especially in rocky areas. Piranhas work GREAT cutting thru vine and bramble roots. I try to cut them just under the surface. I've about 400 acres of land with virtually no rocks in Mississippi, and about 35 acres with rocks (glacial till) in Vermont. Rockless won.

What did you use to drill the hole? Shouldn't take much longer going through flat plate unless you cut through hardened material.

Yeah washer did not fit due to reinforcement. Leaving off washer is not a big deal due to low torque on bolt and design of device. A person could alway put a head size flat washer under bolt head as a bearing surface but I don't think it's necessary.

I agree in rocky soil a toothed tooth bar will probably be better... But then again I can't imagine the average user wearing out the piranha.

For Piranha owners; how do they work for taking out saplings? I am considering ordering one for that purpose.

Not sure yet but I will test in a few days.

I have loads and loads of Jap Barberry spreading all over. I wonder how the Piranah tooth bar would do vs. them?

If you keep the two sets of nuts&bolts cleaned and lubed it comes off REAL quick and easy (but HEAVY and SHARP). A drilled pin with a cammed fastener might work.

Yes, I must have been drilling thru hardened material. I couldn't make a dimple in it with a nail set. I used cobalt drill bits and took it slow, easy and lubed with chain oil. I kept it from "skittering" by using a jig I had bought about 15 years ago with this in mind
I ended up drilling 1/8, 5/32, 1/4, 5/16, 3/8, and finally 1/2. Probably overkill but when I tried skipping a size the drill would "grab", so I just used most of them.
After the 1/8 pilot most went thru quickly.

How big is a "sapling"? 1" DBH? 6"DBH? And how big is the tractor? I've only used it on 1" or less with my M4700, cutting them off about or below ground level. I would expect a BX1500 to have problems with 4" saplings.

At or below ground level I'd expect it to work fine.

That was some serious drilling!! The reinforcement must be hardened steel. Nice work on getting it done! (0:

I have a piranha on my L3800 and have had much success clearing 1" to 3" hard wood saplings. If you can catch the sapling about 3 to 6 inches above the base, they generally pull right out of the ground or just sheer off.

That's really amazing it grabs those small saplings! I'll have to try it!
