I have a Cyclone Rake XL (yellow 10 inch one) for like 10 years. I Originally ran this device behind a crafsman riding mower. Totally burned the transmission on the RM and ripped the cheap pin tab hitch off the RM due to the weight of the XL. It did its best...
Had a warranty issue with something on the CR and they fixed it no problems. No complaints.
I suck up probably 1 acre of oak leaf litter on just bare/wild grass/dirt "lawn". I would NEVER want to do this without a leaf vaccum. As another member said, it produces an insane amount of dust. I like to do it after it rains because of this.
There are times I cannot life the CR because its so heavy full of material. It clogs all the time at the mower deck. i have some ideas how to improve this, but free time is not my friend. I have to unhook it to clear the clog. Annoying, but workable.
4 years back, I bought a BX2680 and it does FANTASTIC towing the CR. ZERO complaints about that.
