How Big of a Mower Do I Need for 1 Acre? (Solved & Explained!)

Having a mower with a cutting deck width that ranges between 14 inches to 28 inches is ideal for an acre of land. You could get one with a larger deck, which will reduce mowing time. But this will depend on the surface and general terrain.

How Long Does It Take to Mow an Acre of Grass?

Depending on the size of the cutting deck and speed of the engine, an acre of grass can take as little as 15 minutes for something like a 50 inch. But, it could take as long as an hour for a 20 inch cutting deck.

There are several kinds of mowers: zero-turns, riding mowers, hand push and even robotic ones. Each has different characteristics and functions that can handle different types of terrain and lawn layouts.


Robotic mowers are often electric or battery-powered and are around 20 inches wide or less. They operate with sensor technology, so you program the mowing area and it does the job without much effort on your part. Robotic ones offer low maintenance, but also GPS tracking capabilities. This does raise privacy concerns depending on the brand.

Riding Mowers

Riding mowers are most ideal for one-acre lawns. They have a huge range of cutting width, from as little as 24 inches to as much as 60 inches. While they do cost a bit more, they’re worth the investment and offer an easy way to mow.

Hand Push

  • Battery-Powered: Hand push mowers that come powered via a battery are usually cordless models you have to charge. While there are a few on the market good for mowing an acre, it’s important to pay attention to how long the battery holds the charge in relationship to the size of the cutting deck. These can get as large as 40 inches.
  • Manual: Also called a push reel, this is the most affordable kind of mower. While the cut width is usually never more than 18 inches, it can take quite a bit of time to mow an entire acre of grass. However, the terrain of the lawn may warrant the use of a push reel in certain circumstances.

Zero-Turn Mowers

Zero-turns offer the best maneuverability and ease of handling. They can come in a range of sizes for the cutting deck. There are ones that are 30 inches and others as high as 74 inches. Often better for commercial or industrial operations, there are some models available for residential use.

Which Kinds of Mowers Are Advisable for an Acre of Grass?

  • Forest-Like Terrain: Bumpy, bulbous and uneven lawns should use a hand push mower. This will offer more control in narrow, tight areas and work around trees, bushes and other such objects. But, it should have a smaller cutting deck to handle the roughness.
  • Rocky & Uneven: Gardens and landscaping often has plentitudes of rocks, stones, pebbles and other such solid objects. Using a hand push or robotic mower will be best for this. The robotic one may be ideal to guard against flying debris.
  • Steep Inclines/Declines: A riding lawnmower designed for hills will be best for an acre. Manual ones will require a lot of physical force and will tire average user easily. Plus, a riding mower offers more speed, which is good for steep inclines.
