If necessity is the mother of invention, laziness is the grandaddy.
I have almost a half acre which gets covered in oak leaves during the fall. I have to get them all to the burn pile on one end of the property which usually involves blowing them into separate piles and transporting each pile to the burn pile a bit at a time.
I figured there has to be an easier way to do this.
I used a leaf blower/vac, a 4" flexible hose, and an insulation disposal bag that I had leftover from another project. It works pretty good. Actually better than the vacuum does with the shoulder bag probably because the airflow isn't as restricted.
I thought the same thing when I bought my house with a ton of trees around but If you don't remove the dead leaves near your house bugs and rodents start coming closer and closer to your home and eventually inside.
If you allow leaves to pile up near a structure it also accumulates more moisture that's not good for the foundation.
If it gets dry where you live it's a fire hazard.
Also if you leave a huge pile of leaves apparently it kills all the stuff under it. Oops. Lol
They said half acre so that sounds like a lot of land but my lot in 1/3 an acre and it's just a normal lot with a house. I also have oak trees.
