Eric,
Do you have a PP?? If you do it sounds like your reluctant to use it and not using it to it's full potential.
I waited a long time for something like this to hit the market. I jumped on one when they were first introduced by Technic Tools.
It's like any other power cutting tool in this business, it's only as good as the knowledge and skill of the person using it. You can do the same things with a PP on the ground, working above shoulder height and do it safely, the same as you would with a chain saw in a tree. You can do jump cuts on small stuff to avoid hitting targets, notch and hinge type fold cuts or side notch larger limbs and guide them away from the person doing the cutting. Many a time I've cut small sections and let them hang by the last fibers of the wood, then finish cut the piece to avoid hitting things like fences and fancy yard ornaments, flower beds. Undercutting and top cuts in three to four sections work great for larger material keeps pieces falling straight and hitting flat on the ground.
The only time a PP can be a real danger is when the shaft is fully extended, working directly overhead in the 11 to 12 o'clock position, the shaft can act just like a speed line and directs the cut limb right on top of the operator. If your aware of this just cut it smaller that's all.
As far as it's use in a tree is debateable, it has it's place in some cases. I would only use it only in extreme circumstances and making sure I had total control of the situation.
Hey Brian,
If you got a new HT- 75 for your birthday what are you going to get for Christmas, a new boom truck???
Is there any way your dad could adopt me, I've got a birthday coming up and could use a new PP..
