I maintain properties with very little trees on them so I don't do much leaf work at all. Yesterday I received an email requesting a clean up. I went to look at it and it is approxiamtely 2/3 of an acre wooded lot. There is no real lawn area so the entire lot will need to be done with a back pack blower, tarp and rake. The leaves were wet but I would guestimate they blanketed the entire lot at 4-6 inches. The leaves can go in the woods at the back of the house. 75% of the property is in front of the house though. Also the property slopes up from front to back at maybe 20 degrees. I know a picture would help but approximately how many man hours do you think this would take based on the info provided? This will be done by me, myself and I with the above mentioned tools. Thanks!
