Thank you, John, Donald, and Rick.
An under the table switch machine would be a good choice except it would stick down into the yard area, and even if it cleared the tops of the cars, I would be bumping it. Someone with better skill than me could maybe put it under the yard and rig a linkage up top, I suppose. I have one Tortoise I bought years ago, but never used, because I ended up using manual throws. I know it would hit boxcars and even open hoppers.
Donald, I did not realize the DZ2500 is much shorter. This is the first I have used Z-stuff and just bought a bunch of DZ1000s. I'll have to look at the DZ2500. Thank you.
Rick, We did that back home, although since they just blew over the hill to the weeds by the crick they became no one's problem. Here, there is a chain link fence at the lower rear of the property that my wife's grandma had put in when she lived here. To the east of us, the guy has let a bank grow up in weeds, so they leaves swirl around at the edge of our yard and the dog tracks them in. I was just watching them swirl while I was washing lunch dishes. We actually only have 3 trees now, but we get leaves from across the road and the neighbor to the west. If I don't do anything, they blow down to the garage door and swirl around coming in anytime you open the door. The same thing happens at the patio that is at the back door. Everything works against me! 
No wonder my mother-in-law wanted us to buy this place from her so badly! 
At least this year I am not working, so I can blow and grind up leaves on weekdays instead of working at night with the floodlights on as in previous years.
