Rhino stumpgrinder teeth


I run a Predator 450 with the 27hp engine and a 6 point multi tip cutting wheel.

I was loaned a set of these teeth by the manufacturers (Magnum Alpine) to try out. They supplied six ‘standard’ and two ‘large’ teeth.

They should be used on a Rhino wheel but I had contacted them to check if they are compatible with my multi-tip wheel.

The teeth fitted ok – using the rhino keeper blocks. I have tried the multi-tip keeper blocks and they fit just as well.

The cutting performance is much better with the Rhino teeth. They demolished all sorts of stumps including holly and oak very quickly indeed. I would say the downward cutting is 2-3 faster though the slewing is probably about the same.

The teeth are a straightforward horseshoe shape about 30mm wide so they are easy to sharpen. I have only sharpened them once but the cutting afterwards is very good.

The teeth look as if they are machined rather than cast, and the keeper blocks are a very tight/precise fit.

We found the debris was cleared better by keeping a pair of old multi-tips in the two inner-most positions and running Rhinos in the other four.
Bear in mind this is running on a multi-tip wheel and NOT the Rhino – so there could be further gains with the full Rhino set up.

The cost of the Rhino teeth is about the same as multi tips but they are very easy to sharpen.

Overall I would say they cut faster (considerably), cost about the same as multi-tip and are easier to sharpen.

I recommend people to consider these teeth.
I have also recently been informed that the distribution of Rhino teeth and wheels will be through Rotatech (formerly Saturn Machine Knives).

Very cost effective and easy to use.
