Give us a little more info please.
1. How big are the trees??
2. How much is "a little" help
3. What happens if things go wrong?? Structures in the way?? or just dont want to hit another tree??
IF the help they need isnt too much, some felling wedges and good technique is the easiest. But dont trust that if there is a building within reach.
Another way I have done it with trees up to ~12" or so is use the FEL elevated high and pushing. PArk the tractor at the tree with a little tension pushing. Cut the wedge and back cut but leave a good bit of hinge, then start pushing on tractor. How I'm not recommending this, especially if trees are larger, cause unless you know what you are doing, you can drop the tree on the tractor. If you cut too much of the hinge, or if the tree is dead and snaps, it can flip over the loader and land on the tractor/operator.
