JohnMiller3 said:Here's another example of a Severe duty "stump jumper" (correct term is called Blade Holder on these monsters...)... on a Rhino Treecutter rotary cutter, from the rear of the unit, notice the blade bolted to this 1 1/4" thick steel disc... this is "1" of four blades mounted on this animal...
By the way... this stump jumper alone weighs over 625 lbs... /w3tcompact/icons/blush.gif

I work for Rhino and we still have those gearboxes and solid plate carriers for that treecutter. I've been selling em pretty good on eBay. I'm in charge of getting rid of all the older or excess materials like this.
