• Rotary mowers use a fast-spinning blade. They cut grass by hitting it. They work well for most lawns, especially taller or thicker grass.

• Robotic mowers cut your lawn by themselves. They save you time. They are quiet and good for the environment. They are best for small to medium-sized lawns.

• Consider your lawn size, how much money you want to spend, and how much work you want to do. This helps you pick the best mower for your yard.

• Regular care keeps your mower working well. Clean it often. Sharpen blades when needed. This makes your mower last longer.

Reel Mowers

How Reel Mowers Work

Reel mowers are a traditional type of lawn mower. Many people know them as push mowers. They use a unique horizontal slicing action. This action involves multiple blades and a cutting bar. The spinning reel itself does not cut the grass directly. Instead, the cutting happens where the spinning edges of the reel meet a stationary cutter bar. This bar is at the rear of the mower. The reel’s cylinder scoops up the grass. It guides the grass towards this cutter bar. This process is similar to how a barber uses a comb to position hair for cutting. This scissor-like mechanism provides a very clean cut.

Reel Mower Advantages

Reel mowers offer several benefits for your lawn’s health.

• Clean Cut vs. Shredding: Reel mowers use a scissor-like action. They lift and cut individual grass blades cleanly. This prevents the ‘white-tip’ condition. This condition makes grass tips turn white or brown. Rotary mowers often cause this by chopping or tearing, especially with dull blades. A clean cut means a healthier and better-looking lawn for you.

• Natural Fertilization: Reel mowers let grass clippings fall back onto the soil. These clippings act as a natural fertilizer. They return nitrogen to your lawn. This helps enrich the soil and improves overall lawn health.

• Environmental Impact: These mowers are often human-powered. They do not produce air pollution from fossil fuels. This indirectly benefits your lawn’s environment. They also need less frequent blade sharpening than rotary mowers. This reduces maintenance and resource use. Reel mowers are also much quieter than other types.

Reel Mower Disadvantages

While reel mowers offer many benefits, they also have some limitations.

• Manual Effort: Pushing a reel mower on uneven surfaces requires physical effort. This can lead to inconsistent blade-to-ground contact. The result is an uneven cut.

• Height Adjustments: Adjusting the cutting height on uneven ground can be difficult. Reel mowers have fewer adjustable features compared to other mower types.

• Obstacles: Rocks, roots, and dips can block the mower’s path. These obstacles can damage the blades. This increases maintenance costs for you.

• Grass Conditions: Reel mowers work best when the grass is not too long. They are also less effective on wet or undulating lawns. You might struggle if your grass is overgrown or damp.

Ideal Use for Reel Mowers

Reel mowers are perfect for specific lawn types and conditions. They excel at maintaining lower mowing heights, often under an inch. If you have a small, flat lawn, a reel mower is an excellent choice. They are also ideal for certain grass species.

• Annual ryegrass

• Bermudagrass (seeded and hybrids)

• Colonial bentgrass

• Creeping bentgrass

• Dichondra

• Hard fescue

• Kentucky bluegrass

• Kikuyugrass

• Perennial ryegrass

• Red fescue

• Rough bluegrass

• Seashore paspalum

• Tall fescue

• Zoysiagrass

If your lawn features these grasses and you prefer a very short, manicured look, a reel mower will give you excellent results.

Rotary Mowers

Rotary mowers are a common type of lawn mower. They use a different cutting method than reel mowers. You will find them suitable for many types of lawns.

Rotary Mower Mechanics

A rotary mower works with a single blade. This blade spins very fast around a vertical axis. The spinning blade cuts the grass by impact. Think of it like a propeller. This action is effective for cutting medium to long grass. The blade’s speed is important for a clean cut. The RPM of a rotary mower blade does not directly relate to its tip speed. Blade lengths vary. Tip speed is usually measured in feet per minute (fpm). Some users operate their mowers at 3300 RPM. They suggest higher engine speed helps cut thick turf. One user increased their 21-inch mower from 2600 RPM to 3500 RPM. They noted improved cutting.

Gas Rotary Mowers

Gas-powered rotary mowers use an internal combustion engine. This engine powers the spinning blade. You often find these mowers on larger lawns. They offer strong power and do not need an electrical cord. An ExMark Lazer S zero-turn mower shows their fuel use. This model has a 60-inch deck and a 27hp Kawasaki gas engine. It uses about 1.5 gallons of fuel per hour. This happens when it operates at wide-open throttle and mowing speed. These gas-powered rotary mowers are powerful tools for your yard work.

Electric Corded Rotary Mowers

Electric corded rotary mowers get their power from an outlet. You plug them into a standard electrical socket. These mowers are quieter than gas models. They produce no emissions. Most electric mowers in North America use 120V household current. They typically feature 13A motors. This limits them to about 1,560 Watts of power. In the UK, 230V electric mowers usually have a power output between 1200 and 1600W. This is similar to their 120V counterparts.

Battery Rotary Mowers

Battery rotary mowers run on rechargeable batteries. They offer the convenience of corded electric mowers without the cord. You get freedom of movement. These mowers are also quieter and produce no emissions. Battery life varies by voltage platform.

Most Canadian yards can be finished on a single charge. You need an appropriately powerful battery mower. Weekly mowing sessions often last between 20 and 30 minutes.

Rotary Mower Advantages

Rotary mowers offer many benefits. They are very versatile.

• Handles Tough Conditions: Rotary mowers have heavy, high-powered blades. Their thick blades cut through saplings and dense vegetation easily. They clear overgrown brush, grass, and trees effectively.

• Cuts Taller Grass: These mowers handle taller and thicker grass more easily. They are not designed to mulch it as finely as finish mowers.

• Robust Design: They are more robust. They handle obstacles like rocks and sticks better. Rotary cutters are more forgiving of occasional rocks. This is true compared to mowers with traditional fixed blades.

• Traction: They maintain traction in wet and hilly conditions. This is due to all-wheel drive CrossTrax® systems and turf-friendly tires. They power through thick grass. They still provide a clean, finely manicured finish.

Rotary Mower Disadvantages

Rotary mowers also have some drawbacks.

• Noise Levels: Gas-powered rotary mowers can be quite loud. They typically produce noise levels from 85 to 100 dB. The average decibel level for a gas-powered lawn mower is 90 dB. This can be disruptive.

• Less Precise Cut: The impact cutting action can sometimes tear grass blades. This is especially true if the blade is dull. This can lead to a less healthy look for your lawn.

• Maintenance: Gas models require fuel, oil changes, and spark plug maintenance. Electric models need battery charging or cord management.

Ideal Use for Rotary Mowers

Rotary mowers are great for many different lawn types. They are effective on ‘semi-rough’ mowing. This includes former hayfields. You can use them on various lawn sizes. The Toro Groundsmaster line offers cutting widths from 60 inches (152 cm) to 192 inches (488 cm). These mowers can achieve productivity rates of up to 20.9 acres per hour. This makes them suitable for small to large areas. They even work well for wide open public spaces. Rotary cutters do a very nice job mowing grass. You just need to keep your ground speed reasonable.

Robotic Mowers

Robotic mowers offer a modern solution for lawn care. These advanced machines handle mowing tasks for you. They provide a convenient way to maintain your yard.

How Robotic Mowers Operate

Robotic mowers work autonomously. They navigate your lawn without direct human control. These devices, sometimes called “Automowers,” use sophisticated technology. For example, they use RTK GPS navigation technology and georeferencing alerts. Some models use Visual SLAM for 3D mapping and positioning. Others combine integrated GPS with a camera system. This allows them to understand their surroundings and cut your grass efficiently.

Robotic Mower Features

These mowers come with many features. Safety is a key aspect. Autonomous Mowing Robots™ include a complete Safety Interlock System. They use LiDAR technology for 360-degree object detection. This stops them automatically for people, animals, or vehicles. You will also find on-machine emergency stop buttons and a Remote Stop handheld unit. Geofencing controls boundaries. Operator authentication requirements add security. Remote-controlled mowers also feature anti-tilt-and-drop sensors. These shut down the machine if you do not hold the controller safely.

Robotic Mower Advantages

Robotic mowers offer significant benefits. They save you time. Homeowners with a half-acre lawn save about 60 hours per year. This means you save over an hour each week. These electric mowers are also good for the environment. They produce zero direct emissions. Their carbon footprint is much lower than gas mowers. They operate quietly, usually under 60 dB. This is like a normal conversation. These rechargeable lawn mowers also mulch grass clippings. This returns nutrients to your soil.

Robotic Mower Disadvantages

Robotic mowers also have some drawbacks. The initial cost can be high. Models can range from about $1,900 to nearly $14,000. Commercial units can cost over $33,000. They also have limitations on lawn size. Some robot lawn mowers, like the LawnMaster OcuMow™ R1600, cover up to 1,600 square feet. This makes them best for smaller yards.

Ideal Use for Robotic Mowers

Robotic mowers are ideal for people seeking hands-free lawn care. They suit small to medium-sized lawns. If you want consistent mowing and enjoy smart home technology, these are a great choice. They work well for those who prefer quiet operation and an eco-friendly option.
