Both Honda and Toro make great machines. I personally own several Toro push mowers and many of them work great. Choosing a push mower should be based on what you need to get the job done quickly and efficiently without any headaches.
First we'll start with the size of your yard. If you have a fairly small yard like in a small development, that you would really only need a 20 inch. In the middle you have 21 and 22 inch models, where you have a bigger variety of the types of mowers you can get. There is also a large 30" mower that Toro makes, and is a personal favorite of mine. Choose between needs and your budget.
Now we have to choose the self propelled system. First is the FWD, which is the most inexpensive option. It works great on flat ground and can work on small hills and some minor terrain. You also have the most maneuverability and is way more comfortably to turn since the front wheels are the only ones that move. However, they cannot climb steep hills or go over rough terrain because the wheels have a tendency to slip. Next we have the RWD. Slightly more expensive than the front wheel drive, the rear wheel drive models, provide better stability and control when going over hills or rough terrain, and does well on straight aways. Its maneuverability is lowered greatly since the rear wheels are in motion, so you would have to stop the propulsion, make your turn, and then re-engage the propulsion. With practice however, it gets a lot easier. Lastly, there are AWD models, which are relatively new. These are the most expensive option, but offers you the greatest stability on the roughest terrain or on steep hills. Maneuverability is in between the FWD and RWD. They are also great on straightaways.
The engine choice is usually a matter or personal preference but I would go with Briggs and Stratton. Thats just me. If you do get a Honda, your obviously getting a Honda.
The personal pace setup on Toro walk behind mowers work rather well. The faster you push, the mower will try to match your pace. To many it may seem a little cheap, and that was my first impression until I tried one and found out how well it worked. I do not think that anyone makes the manual speed selector for push mowers anymore. I used to have a Toro Super Recycler Pro II that had a 3 speed on it.
FWD Pros:Inexpensive, Excellent Maneuverability, Good for flat ground
Cons: Not good for hills or rough terrain
RWD Pros: Well balanced between FWD and AWD, Good for flat to moderate slopes or terrain
Cons: Difficult to maneuver
AWD Pros: Great Traction, Good for larger sloper and rougher terrain.
Cons: Expensive, maintenance, Slightly difficult to maneuver
Some mowers come with extra features that might make your mowing experience a lot better. Many today come out with a washout port, where you insert your garden hose into a plug and clean it while the mower is running. This works great with some mowers. Some have electric starters, where you just have a turn or a key. They are really handy, but keep in mind that the engine does not charge the battery, so you will have to charge it at least once a season.
Many mower have different discharge modes for different mowing conditions. Mowers can have a 3-in-1, a 2-in-1, are strictly muches. Toro mowers make it easy to quickly change from different modes. Pretty much every mower out there has the ability to mulch clippings. Some do it better than others. The Toro Mowers do this very well. This should only be done when the grass is no more than an inch taller than its cutting height. Mulching should not be done when the grass is wet, when there are leaves, or if the grass is too tall. This would bog the mower down and will cause great irritation. A side discharge is an option for 3-in-1 mowers. This is good for year round work. You can side discharge clippings if there is a lot of grass or if your lawn is super thick. A lot of mowers today have a bagging system, which will pick up clippings and put them into the bag. This will provide a much cleaner looking cut and is better for picking up leaves or lots of grass. You will have to go through the time of dumping the clippings somewhere, and the bags can fill up pretty quickly, especially when sucking up leaves. If you have a lot of leaves in your yard, I would recommend getting a leaf vacuum. Sucking them into those tiny bags is way to inefficient and irritating.
