For dry leaves this would be fine I’m sure, but the problem is wet leaves which essentially turn to slime that would just be spread along the track by a system like that. If you’re in a locale where leaves fall in the autumn, next time you’re out on after a rainy day find some half decomposed leaves around a puddle and you’ll see. They break apart into a very slippery goo.
