By using a lot of rope and system of pulleys and this is actually a crank so that the weight could be lowered slowly and then pulled as it comes down away from the home, then completely lowered. We had a 3 man ground crew and one climber 4 in total to be able to do this job. One guy worked the crank, and two or three to pull the branches out into the grassy area, the customer also had a number of plants around the tree that he did want damaged. Pretty tall order for most companies!! NOT SUNRISE no problem.
