See if you can find a Cyclone Rake user in your area to get a demo. If you go on their website, they can get you in touch with someone. Their videos are very accurate, they are worth watching.
The smaller the deck they are attached to, the better they work. You will be amazed at what they will pick up. I don't even bother picking up much that's less than an 1" in diameter, pine cones, pine needles, leaves. My neighbor had blown leaves from in front of his house last fall. I had picked up leaves at some widows & widower on the street and saw him in his front yard so I stopped in to help him, single law enforcement dad. I raised the deck and drove over the 18" pile and sucked up everything each pass, but it filled the trailer pretty quick. He couldn't believe how easy it made it look. I'm a believer in my Cyclone Rake Commander on my X738 54" deck for sure. I found mine used, 1 year old on Craigslist. Guy had moved from home with lots of trees, to a home with nearly none. I used it on my Scotts L17.542 for several years until I got my X738, but wet/damp leaves in the trailer will pull the back of the tractor around sideways.
I ran my friend's Z10 Cyclone Rake too with his Cub Cadet 54" until he got his Kubota BX2380 54" deck and had the same results, just more leaves. Z10 Cyclone Rake is one of their largest units. You will need a decent tractor to hook one to if you have any slopes. Otherwise the weight of wet/damp leaves will pull the back of the tractor around sideways. He lives in an Oak woods, so he gets lots of leaves. Cleanup around the house and plants is pretty easy too with their long estate hose/wand. Only thing you have to find is someone to drive the tractor around while you suck things up with the wand rather than getting ON-OFF-ON-OFF.... Makes it go quick. Good thing to teach the grandkids how to drive the tractor, but they won't find it very exciting.
That's good you are helping others. I'm sure in your situation it works fine for you but for me I don't think so.
I don't want the cyclone rake even if was given to me for free. Using it in my situation would be double work.
Where do you dump out the contents? I have no place in my yard. I wonder if anyone on their website has asked that question.
Its a second motor I have to start, run, and maintain whenever I do my leaf cleanup. I don't want that.
I'm basically out of storage space between a two car garage and 200 sq. ft. shed.
The cost is the same cost of a new tractor.
They advertise for leaves, acorns and pine needles only. They don't advertise it as a twigs or sticks that gets sucked up through the hose and through the propeller. Twigs and sticks will always have to be raked up.
I won't even use it for just picking up leaves, acorns and pine needles because its double work emptying it out and putting the chopped up material in a recycle container. It would be spilling all over the place trying to get the contents in the recycle container.
When I do my leaf clean up I mulch the leaves first, then suck them up with the bagger, then empty them in large recycle containers that the county government picks up weekly. But prior to that I have to clean out the twigs and sticks otherwise they will cause a flat, mess up the blades, or get jammed up where the belts and pulleys are.
I only have a half acre that's nicely landscaped in a residential neighborhood. Its hard enough trying to maneuver the tractor around all the mulch areas. I use to use a walk behind.
