Mowing a golf green requires a lot of precision and the right equipment. Golf courses use specialised reel mowers to cut the grass at a very low height, and dial calipers to ensure consistency in grass height to the one-thousandth of an inch. The process of mowing a golf green starts with a straight first stripe, and it's important to mow often, cutting only 1/3 of the blade at a time to keep the lawn healthy.

What You'll Learn

Use a specialised reel mower
To achieve a golf-green lawn, you'll need to invest in a specialised reel mower. Reel mowers differ from traditional rotary mowers as they use a scissor-like cutting action, producing precise, even cuts that create the coveted striped effect seen on golf courses.
Reel mowers can be costly, with prices upwards of $9,000 for the type of walk-behind reel mower used on a golf course. Used reel mowers can be purchased at a discount, but they may require expensive replacement parts, such as new bearings, a new bedknife, or a new reel cylinder. In addition, reel mowers require specialised grinding equipment to maintain sharp blades and precise cutting angles.
Before using a reel mower, it is important to prepare your lawn adequately. This includes levelling the lawn to ensure a flat, even surface. Proper preparation is essential to achieving a pristine, golf-green appearance.
When using a reel mower, it is important to mow frequently, sometimes several times a week, to maintain the desired short grass length. Golf courses typically maintain their greens at or below a 0.125-inch height of cut, requiring dedicated upkeep.
By investing in the right equipment, putting in the necessary preparation, and committing to regular maintenance, you can transform your lawn into a golf-green masterpiece.

Mowing frequency
Before mowing, it is important to ensure that the grass is healthy and actively growing so that it can withstand and recover from the injury caused by mowing. If the grass is experiencing any type of stress, such as high temperatures, frozen conditions, or a pest infestation, mowing practices should be adjusted and scaled back.
To achieve straight and consistent mowing lines, it is recommended to start by mowing towards a point in the distance, such as a tree, and then aiming the lines on the bucket at the edge of the previous stripe. It is also important to ensure the rollers of the cutting unit are true and minimise any variance in height, as even a minuscule difference can lead to a noticeable decline in putting quality.
Additionally, the blades of the reel mower should be checked and sharpened before each mowing session, as they can have anywhere from 11 to 15 blades that need to be maintained. This level of precision and maintenance is necessary to achieve the smooth and fast greens desired by golfers.

Lawn health
To achieve a golf course-like lawn, several factors need to be considered to ensure optimal lawn health.
Firstly, the type of grass is important. Golf courses typically use Bermudagrass or bentgrass. Bermudagrass is a warm-season grass that requires full sun and good drainage. It is heat-, drought-, and traffic-tolerant and has a fast growth rate. Bentgrass, on the other hand, is better suited for colder climates. The grass type will determine the mowing height and frequency. Golf greens are typically mowed to a height of less than 0.25 inches to provide a fast and smooth playing surface. However, it is recommended to not mow Bermudagrass lower than 5/32 of an inch, and this height should be raised slightly during the summer due to extreme heat.
Secondly, the right mower is essential. Golf courses use reel mowers, which cut the grass like a pair of tight scissors. These mowers are designed to cut turf at low heights, well below 1 inch. The mower blades require regular sharpening and careful maintenance to ensure precise cutting. The frequency of mowing will depend on the grass's growth rate, which is influenced by factors such as mowing height, nitrogen fertilizer application, and temperature or season.
Thirdly, the health of the turfgrass is critical. Mowing practices should be adjusted during periods of stress, such as high temperatures, humidity, frozen conditions, or pest infestations, to prevent further decline. Cultural practices like verticutting, rolling, and aerification can boost turf health and playability. Additionally, the use of fungicides, pesticides, and herbicides can help control diseases, insects, and weeds, respectively.
Finally, other techniques can be employed to enhance the lawn's appearance and performance. Topdressing, fertilization, and the use of plant growth regulators (PGR) can improve soil quality and promote a greener lawn. Changing the direction of mowing can also prevent ruts and alleviate stress on the turfgrass. It is important to note that mowing too low or irregularly can damage the grass crowns, affecting the colour and recuperative ability of the turf. Therefore, a balanced approach to mowing and turf management is crucial for maintaining a healthy and aesthetically pleasing lawn.

Mowing technique
Mowing a golf green requires a specific technique to achieve the desired results. Here are some detailed instructions and considerations for the mowing technique:
Firstly, it is essential to use a specialised type of reel mower to achieve the low cutting height required for golf greens. Reel mowers create a scissor-like cutting action, allowing for a much lower cut than a rotary-style mower. Before mowing, ensure the 11-15 blades of the reel mower are sharp and in good condition.
Secondly, consistency and accuracy in grass height are vital. Dial calipers and dial indicators can be used to ensure the rollers of the cutting unit are true and that the mowing height is accurate to the thousandth of an inch. This precision minimises any variance in the height of the grass, which is crucial for maintaining putting quality.
Next, the mowing pattern and technique are important. It is recommended to mow from one side to another, avoiding starting in the middle. Picking a target off in the distance, such as a tree, and focusing on that while mowing can help achieve straight lines. It is also important to mow towards a point in the distance, especially when dealing with slopes, to ensure the lines are straight once you reach a flat section.
Additionally, it is crucial to mow frequently. To maintain the health of the grass, only a third of the blade should be cut at a time. With very short grass, this may mean mowing every day or every other day.
Lastly, be mindful of the condition of the grass. If the turf is experiencing stress from high temperatures, humidity, frozen conditions, or pest infestation, scale back mowing practices until the grass recovers to prevent further decline.
By following these techniques and considerations, you can effectively mow a golf green, achieving the desired low height and smooth, straight lines while maintaining the health of the turf.

Equipment maintenance
Firstly, it is important to note that reel mowers, which are typically used on golf courses, have anywhere from 11 to 15 blades that need to be sharpened. This is significantly more blades than a rotary mower, which only has one blade. To maintain sharp edges and precise angles, reel mowers require specialised grinding equipment. Before mowing, it is important to check all the blades of the reel mower and ensure they are sharp.
Accurate gauges are also vital to achieving consistent results. Dial calipers and dial indicators are used to ensure the rollers of the cutting unit are true and that mowing heights are accurate to the thousandth of an inch. These measurements need to be taken before every mowing session, as even a minuscule difference can lead to a noticeable decline in putting quality.
In addition to blade sharpening and accurate measurements, it is important to consider other aspects of equipment maintenance. This includes keeping the mower clean and free of debris, ensuring the moving parts are well-lubricated, and performing regular checks and servicing to identify any potential issues or worn-out parts.
Furthermore, it is worth noting that the condition of the grass itself can impact the maintenance requirements. For example, if the grass is experiencing stress from high temperatures, humidity, frozen conditions, or pest infestations, it is recommended to adjust mowing practices and reduce their frequency until the grass recovers. This proactive approach helps prevent further decline and promotes the health of the turf.
