I think I would also inspect the underside for rubbing, especially since you said the top deck was damaged from something. There might be something stuck to the stump jumper that's rubbing and not obvious. If you could turn the cutter over or lay it up against a tree and do a thorough check of the underside, then you'd know there wasn't a problem with rubbing.
Also, look closely at the bolts that hold the gearbox to the body of the cutter. If they are loose, they could cause noise that is more noticable at lower speeds than at high speeds.
