Some chat about front mounted generators on the main board. Wheelhorse offered two different front mounted generators. I believe they were 3 or 3.5 kW and 5 or 5.5 kW.
Here is a pic:
Here is a better pic of via a youtube video:

Also - chatting with some guys on another color board, someone mentioned front mounted mowers. Wheelhorse offered a front mount carriage that the belly mower would attach to. Not to sure how well they worked, but I guess if you were mowing under trees or fences maybe there was some benefit. Here is a pic:
The first Wheelhorse I bought, I got a 42 inch rear discharge deck for it. For me, the idea was the ability to mow in ANY direction without respect for the clippings discharge. The ability to trim on both sides. Not slinging grass or gravel against the house or car.
Turned out, all of that stuff was possible, but even more. There is pretty much zero vacuum on a rear discharge deck, so when it's dry and you ride over a patch of dirt, no dust cloud. Motor across a gravel driveway, no gravel being picked-up and thrown about. Because the grass is constantly being left behind the mower, there is never a clog issue with mower like a side discharge and you can mow some very tall grass with it.
The down side is it can make a mess of the underside of the tractor and if your grass is very tall, it doesn't really disperse or recut much clippings. When you first mow - with tall grass, you can see the clippings. Lot of folks don't like that - but for whatever reason, if you wait until the next day, they are usually gone. I guess the wind scatters them or they just fall into the lawn. Wheelhorse made a 42 inch and a 36 inch 3 blade rear discharge deck. The 36 inch will fit into the back of a compact truck, like a Nissan Frontier, between the wheels.
The other thing you can do with a rear discharge deck is sweep your grass (or leaves) while you mow. If the grass is soaking wet, the RD deck will mow it and the sweeper will sweep it. If you're good with a sweeper, you can stripe your lawn with it too.
Here is a pic of a Wheelhorse with a front mounted dethacher, mid mounted 42 inch rear discharge deck and a sweeper working some grass - pretty cool IMHO.
