What DD wrote. Collecting & bagging leaves is not worth my time, when I can chop up the buggers in situ.
I bought an electric model. I've had bad experience with small gasoline motors.
I absolutely HATE extension cords. I have neither the time nor the patience to deal with them. That said, that's why I opted for the most reliable small engine made. I swear I started it on the second pull on Saturday and it was 40 or so degrees out. My Weedeater and Toro??? Yeah, right. I'd be pullin' and fiddlin' for 5 minutes.
I have a Husquevarna riding mower, YTH 150 Automatic. I purchased the Cyclone Rake.
I don't have a rider nor could I use it if I did in my yard. I bought the leaf vac for my flower beds specifically. I have pine straw mulch and it's damn near impossible to get the leaves out with a rake and leave the mulch behind. The rest of the yard will just continue to get raked until I can buy a new push mower with a bag for next fall.
