Rhino Teeth on Predator grinders

[swinny]

Need to order some new teeth up soon and considering using the rhino teeth in the stock predator wheel. 

 

Do I need to swap all 6 out? sure ive seen a post somewhere saying they use rhino in the lead and use old multi in the back pockets, but looking at this, surely the sides on the multi stick out more than the rhino so will be grinding also and slowing the machine down? 

 

Last but not least..... I take it the small are more than adequate for a p26/28 machine?

 

or..... stop fannying about and keep with multi tip lol

Whether you need to swap all 6 teeth out depends on the condition of your current teeth. If they are still in good condition, you can get away with swapping out just the leading teeth. However, if they are worn or damaged, it is best to replace all 6 teeth.

 

The size of the teeth you choose will also depend on the size of your machine. For a P26/28 machine, the small teeth should be adequate. However, if you are cutting thicker branches, you may want to consider using larger teeth.

I use them on the leading pockets on a 360 - they do cut more aggressively when new and are easier to sharpen than multitips. 
I order by phone rather than through the website as often after ordering on website they are out of stock.

what is a leading tooth pocket???

[rapalaman]

On the 360 two of the teeth protrude a few millimetres further out, these are the leading teeth. Guessing on the bigger machines it’ll be half of the teeth?

The pocket or carrier is where the teeth bolt into

cool, what is the purpose of this, are they marked? thanks

It’s easy to see the difference if you measure out from the shaft with a stick or similar. There staggered in 3 pairs, first pair does most of the work, second pair does a fair bit and 3rd pair just clear the crap out. 
 

when I had Predetor grinders I used to put a new pair in the leading pair, move the old ones to the second pair and them to the third pair. The old third pair used to go in the scrap bin.

yes you can sharpen them but the time involved was never worth it, just price them into a job.
Unless it was really stoney shit job, in which case I would sharpen on the machine with a batt angry grinder and diamond disc in between changes. I also kept a few in various states of wear so if I broke a tooth it could be changed with one in a similar state to it’s pair to keep the wheel balance.

cool thats good to know, had no idea they were set up like that . although i did notice some teeth were more worn than others.
