Have you ever looked at your neighbor’s perfectly manicured lawn and thought, “How do they get their grass so short?” Maybe you’ve even tried adjusting the height settings on your lawnmower, only to find that it still leaves your lawn looking shaggy. The quest for the lowest cut can be a real struggle, especially if you’re dealing with a stubborn lawn or a lawnmower that just doesn’t seem to be up to the task.
This article delves into the world of lawn mowing and tackles the question of which lawnmower cuts the lowest. We’ll explore the factors that influence cutting height, dissect the pros and cons of different types of mowers, and equip you with the knowledge to choose the right tool for a perfectly manicured lawn.
Short Answer: The lawnmower that cuts the lowest is generally a reel mower, followed closely by rotary mowers with adjustable cutting heights. However, the actual lowest cut achievable will depend on the specific model and the type of grass you’re mowing.
The Factors Influencing Cutting Height
Before we delve into the specifics of different lawnmower types, let’s understand the factors that determine how low you can cut your grass:
1. The Deck Design
The deck is the base of the mower that houses the blades and the cutting mechanism. Its design significantly impacts the cutting height.
- Reel Mowers: These mowers utilize a set of rotating blades that cut the grass against a stationary blade, similar to a pair of scissors. Reel mowers generally offer the lowest cut, as they’re designed for a precise, clean cut.
- Rotary Mowers: These mowers feature a single rotating blade that cuts the grass in a spinning motion. The cutting height is determined by the position of the blade relative to the ground, which is adjusted using a lever or dial.
- Robotic Mowers: These autonomous mowers work independently, cutting the grass frequently and maintaining a consistent height. Their cutting height is typically adjustable, but not as low as reel mowers.
2. Blade Sharpness
Dull blades will cause your lawnmower to scalp the grass, tearing it instead of cutting it cleanly. This can result in an uneven and unhealthy lawn.
- Sharpened Blades: Sharpened blades cut smoothly, leading to a consistent height and a healthier lawn.
- Dull Blades: Dull blades struggle to cut cleanly and can leave a ragged, uneven finish. It’s crucial to maintain sharp blades to achieve the lowest possible cut.
3. Grass Type
Different types of grass have different tolerances for low mowing.
- Fine Grasses: Grasses like fescue and bentgrass can handle lower cuts than coarse grasses like Bermuda or Zoysia.
- Coarse Grasses: These grasses need a bit more height to thrive and can become stressed if cut too low.
4. Mower Maintenance
Regular maintenance, including blade sharpening, deck cleaning, and proper lubrication, helps ensure your lawnmower cuts effectively and maintains a consistent height.
