You may think so at first glance, but it is much safer than hanging off a ladder on uneven ground and working with one hand while the other holds your tools and hangs onto the ladder for dear life! I've done this job both ways, and the PT is much better!!
Raise the Grapple Bucket, with needed tools and materials inside, to the desired level, position the bucket bottom horizontal with the grapple fangs vertical, set the parking brake, and shut off the engine.
Climb into the bucket using a short ladder, or by climbing the arms.
Stand in the bucket using the fangs and fang spreader bar as a reassuring handrail. Now use both hands. If you need extra material or tools, they are right there in the bucket with you! Attach a safety belt to the fang spreader bar, if you want!
