I would think loaded "Turf" tires would help on any tractor on slopes.Lower profile(lower Center of gravity).
Tracked machine are expensive to repair when needed,are slow and not real road worthy.
I think you are looking for a unicorn. I live in avocado country and everyone that I know moves the wood that needs to be chipped to an area where they can safely set up their chipper. I have a B7800 Kubota with loader and it works fine for this. A grapple would be nice but I'm at an age where I'm pretty well done with that sort of work.
Several of the local avocado people are giving up on them because of the water situation etc. and have crews come in and cut down the trees and drag to the chipper. Lots of man power but no one seems to have a better way.
No, I wouldn't take your wheel loader on a slope. But I'd take a Power Trac on a slope all day long. Mowing, brush cutting, FEL, forks, pretty much everything the OP is wanting to do and more. A PT1445, for example, is good for a 30 degree slope and has 1800# of lift.
On slopes, they are better machines than tractors.
With a PT, you would use an adapter to put the chipper backwards on the loader and power it with a hydraulic motor (like you would putting it on a skidsteer).These look very interesting. I had not considered a Power Trac. I have read about these but have never actually seen one. They do not appear to have a std 3pt hitch so would not work with my chipper or other implements. The small tires help keep the cg low, but may limit ground clearance. I have looked over some of the Power Trac posts here and it appears that many people are very happy with them. This is more appealing to me than a tracked loader. I may consider a PT in addition to or in place of a CUT. I will have to learn more about these. Thanks!
