A word of caution on pushing trees over.
I have a brand new (in 2012) Kubota M7040, Deluxe cab, FEL, my first new tractor, my baby.
I pushed over several pine trees about 20' high using the FEL and my very heavy blower on the 3 pt. Very proud of myself and my tractor
Then I pushed one over and had a hard time backing up.
The stump and root ball came up under my tractor as I pushed. It snagged the guard for the fuel tank which had an angle arm bracket as the leading edge of the guard.
The angle arm was ripped off the aluminum under-pan for the fuel tank.
6 years later I still see the bend angle piece under my tractor and leave it as a visible reminder.
Now, I use a ladder and get as high up in the tree as I can and attached a very strong nylon tow strap for larger trucks.
I use the strap as it is much easier to lift than my 50 ton rated chain.
Now I assemble enough chain so that I am far back from the tree and cannot be hit as it comes down.
If needed, I can move around the tree leaving the strap in place and dragging the chains.
This is why I am a strong advocate for the puller with the additional hydraulic cylinder. Someday I hope to buy one.
