This Troy-Bilt self-propelled lawn mower with a bagger is a really good mower. I've had it for a few years, along with another brand, and this is the one I prefer to use. It propels itself well, although it does have a bit of a problem with a relatively steep hill in my yard. That one area requires more pushing, but it's a small area and easy to deal with. Performance The lawn mower works well. It doesn't go too fast when the self-propel lever is down, and it cuts evenly. Handling This is a fairly heavy mower, especially when the bag is halfway full or more, and it's a bit on the larger side for a push mower, but it maneuvers well. Durability I've had this mower for several years and used it fairly heavily and have had no problems with it. Safety The safety stops work well. I don't see any safety issues. Ease of Use The mower is easy to use except for one thing. The bag can be difficult to remove and then put back on. There is a heavy plastic flap covering the entrance to the bag that does not stay open on its own. So you have to use one hand to hold that up and then the other to pull the bag off and then put it back on. There have been times when I've had to get help with the bag. Engine Power The engine power is good, except for the steep hill.
