My brother had a White. It was self-propelled.
Ended up not using it much.
If you watch the video ads, you'll notice that the leaves are all on top of the grass.
A vacuum will do that job easy. When the leaves are stuck down IN the grass, things get a bit harder.
His could put a large diameter hose on the front if he wanted.
He sold it.
Th mower type of vacuum might work better for most people.
