Make sure the engine oil pickup doesn't get uncovered at extreme angles

I kept an eye on the gradient gauge on the engine

Interesting I've not seen one.

 

When I tested our tracked chipper at 35 degrees for the CE technical file I found the Hatz engine oil pick up had to be factory modified.

This one didn’t look too bad when I quoted it - about 4 1/2 ft across ash stump that the guys who felled it had had a go at grinding and failed - just scratched the top a bit. Once we’d dug around it, removed bricks, lumps of flint etc it turned out to be about 7ft x 8ft so set to it with the predator 360 (I know, too small and I’ll be upgrading hopefully later this year)

well 8 hrs, 4 resharpens and two new rhino teeth later, the hole is now 2ft deep but mission accomplished and a happy customer!

Some rushed pics of some of the past 2 days stumps, 20 stumps in total, most 1-1,5 m diameter.
dead ash, elm, oak, few fresh spruce 
went through about 15 teeth (lots of rock here) roughly 40liters fuel
no cleanup
