They sell vaccuums for leaves.
Way too slow.
Dealing with leaves is easily the best money I've made during the past 25 years.
1) Blow them into common areas about six to eight feet in diameter.
2) Stand in the middle of those areas and rake to the center for an easy pile.
3)
Most important step....Have your bags on hand and then
get down on your knees to sweep the newly condensed piles into the bag with your arm.
About four or five good sweeps and the bag is near full. Scoop the rest by hand and complete the fill. Tie the bag off and either complete that pile with next bag or move to next pile.
If you try and "bend over" to scoop up the leaves and then place them into either a loose bag or a bag that has been fitted into a rubber trash can, you will take about 5x as long and you will likely find it difficult to get out of bed later this evening or tomorrow morning because your back is not designed to repeatedly bend at the waist and lift ANYTHING.
Once I've got my leaves condensed and raked into tighter piles, I can fill 30 bags in less than an hour.
4) Don't insist on stuffing each bag to the maximum fill. That just makes them heavier to tote to the curb, street or truck (if you're taking them elsewhere).
Instead of max filling 40 bags, spring for the cost of about 55-60 bags (about 15cents a bag) and make the lifting and toting much easier.
5) Use 1.1ml bags for optimal benefit. Filled to 90%, they should weigh less than 20 lbs and they won't tear like the cheaper .85ml bags do when filled.
Using the thicker "contractor" bags is overkill, imho. They're twice the price and when you fill them, they'll weigh about 35-40 lbs each
Once you get this system down, you can blow, rake 40 bags worth in about 90min and then at most another 90 min to bag it up.
Residential homeowners have been paying me between $25-35 an hour (plus surcharge for bags) for years.
You might find it a pretty handy way to make money in your community, especially from Oct-early spring.
Your only overhead is a good rake (nice wide with sturdy attachment to shaft so you don't snap the shaft) and a good blower. ($89-129 at Home Depot).
Mix the gas right and don't run it for more than about 30 minutes uninterupted (rake in between) and it should give you a solid 200+ hours of service, during which time you can earn $4-5000 or more.
