cmsedore, I have the Kubota L4610HSTC and except for not enough cooling power in the A/C, I am mostly pleased. I too, have been dropping a few Juniper trees (locals call them cedar, but they aren't)
Let's compare notes on processes and results. I did about 50 trees in one morning. Largest were over 20 ft tall and about a foot or so in diameter. Smallest were just seedlings. I concentrate on the ones with berries as they are the females and the birds eat the berries, coat them in fertilizer, and plant them all over the pastures. I use the FEL to reach up and scrape branches on the side near me. I point the blade down and use it like a carving knife. This allows me to get close enough to push on the trunk without putting branches in the grill, radiator, or windshield. I reach up quite a ways and push with the FEL bucket which rears the fron wheels off the ground a few feet. If the tree goes over it is a soft landing due to the branches on the other side. If it doesn't then I back up and check the near side roots to see if any broke the surface. If yes then I dig at them a bit to weaken them and push on the tree again, usually lower down. If I push too hard and too high it breaks the trunk and leaves a stump or if I don't loosen the near side roots enough. Pushing too low is a waste of time. Root systems seem really shallow on this species.
Might save some trunks for posts as "cedars" have been used historically for posts with good results. I will run the rest through the
chipper and burn anything that is ill behaved or in excess to my chip requirements (not too likely).
I have it on good authority (extension agent) that if you cut one down below its lowest limb it is dead. If the weather were cooler and I wasn't looking for tractor jobs, whacking them at ground level with a chainsaw would probably be easier, if yoiu aren't going to plow the area.
What is your approach and how well does it work?
