To be honest. I thought the 48" could use another couple ponies when I went over the leaf piles, but then again, the engine only had just over 3 hours on it. It didn't really bog down at all, but I could clearly hear the governor open a bit to keep the RPM's up, and the leaf piles weren't that
deep that it should have had to open up at all IMO. I couldn't help but think at the time that if it had a mulch kit it would definitely need more power.
