Best Zero Turn Mower for Hills in 2021

One of the most dreaded chores to do is mowing your lawn, that is until riding mowers came into existence and it has become a source of home amusement. However, as fun as ZTR mowers may be, it’s a question on whether or not they can mow the grass on hills. To help you out, I’ve tried multiple zero-turn mowers and tested how well they do over sloping hills. I’ve listed 5 of the best zero turn mower for hills to help you make your pick.

Are zero turn mowers good on hills?

Simply put, YES! they are. Zero turn mowers are good on hills that's not steeper than 15 degrees. ZTR are quite costly but they come at the price of premium safety and security. These lawn mowers also don’t make you circle back to where you’ve cut, unlike a lawn tractor. This means that it can mow through the slopey areas in your property and still manage to give your lawn a nice clean cut.

However, like most riding mowers, steep hills are already a big challenge. Mowing a steep hill is, in itself, quite dangerous and it’s always recommended that z-turn mower don’t go over slopes steeper than 15 degrees or at most 20 degrees.

Considerations When Choosing a Suitable Zero Turn Mower For Hills

  • Slope of the hill

This can be tricky to figure out, especially if you don’t know how you’re going to measure the steepness of the sloped areas around your property. But in determining the slope of your hill, compare it to a highway. If your slope is steeper than normal highway slopes, then it’s over 10 degrees in angle.

Highways aren’t constructed over 10 degrees in angle. You should also try standing at the steepest part of the hill and see if you’re either having a hard time keeping your balance or you’re putting effort in keeping your center of gravity, then this means your riding lawn mower won’t be able to do the same.

Though they’re not accurate in measuring the steepness of the hills around your property, it’s close enough to understand if a riding mower is suitable for it at all. Still, it’s best to use a slope indicator.

  • Manufacturer recommendations

Most manufacturers would recommend the steepest slope their machine can handle. However, without any indicated slope, most mowers can handle up to 15 degrees. In other cases, especially larger mowers with powerful engines, they can go up to 20 degrees but nothing more than that.

  • Safety features

All ZTR mowers are equipped with multiple security measures to ensure the safety of the rider, but one of the most important features to remember are the brakes and the rollover protection system. A powerful and accessible braking system will make it easier for you to immediately put your machine to a stop when you’re starting to sense the danger of mowing.

A rollover protection system is also handy since it would help maintain the center of gravity of your machine.

  • Mower weight

This consideration is highly controversial, some would say choose a lightweight machine since it would ease through a hill, while others would opt for a piece of heavier machinery.

As it turns out (after trials and errors) I’ve concluded that going for a heavier unit is better. It has more safety features added and it also has a heavier and more secure grip on the ground.

Heavier machines have a wider center of gravity making it less like to topple over. See "How much does a zero-turn weigh" for more pros & cons and comparison between heavy and lightweight z-turn mowers. 

  • Transmission: Automatic or Manual?

Manual transmission is great for a lawn mower that is if you’ve fully mastered riding your ZTR. Plus, it is quite different from driving a car. It’s a bit difficult to keep changing gears when you’re going downhill then uphill. An automatic transmission easily adjusts to the changes in slopes and will also help you move your way over a hill with ease.

  • Engine Power

A powerful engine is needed to keep your mower well-balanced when going over a hill. And with a zero-turn mower’s twin-engine, it improves that stability of your mower. However, a powerful engine comes at the expense of more fuel consumption.
