2 min read | Spring is finally here and it's time to get out the spreader and start working on your turf for the big summer season. But before you go zipping out of the shed and across the grass with the fertilizer, there are a few settings that need to be addressed to make sure you get the turf you've been dreaming about all winter.
Fertilizing turf is a great way to get that dense, lush look that people love and also helps keep the weeds at bay. The Lely Turf Fertilizer Spreader Calibration Tool is a great resource to double-check your scale settings and speed to ensure the best output of that fertilizer. Not sure your output is where it should be? We can help.
To determine the output rate, begin by checking the calibration stop that is recommended in the Calibration Guide, which can be found in the Owner's Manual. Fill the hopper with a known small quantity of fertilizer and measure the area covered as the hopper empties (working width of the spreader x feet covered).
For example, if your working width equals 40 feet and the distance driven equals 100 feet then your output rate is 40 feet x 100 feet or 4,000 square feet.
If you want to spread 250 pounds per acre of coarse granular fertilizer and have a forward speed of 3.5 mph, according to the calibration chart you would need to set the machine calibration to six.
We know that an acre is 43,560 square feet. At 40 feet working width, we know they would travel 1,089 feet to cover a square acre (43,560 square feet / 40 feet = 1,089 feet).
While there are several ways to figure the output, one easy way is to break it down by pounds per 1,000 square feet.
For example: 250 pounds per acre / 43.56 would equal 5.74 pounds per 1,000 square feet.
Calculating for 4,000 square feet (100 feet driven x 40 feet working width), then (5.74 pounds per 1,000 square ft multiplied by four would give you 22.96 pounds).
If you followed along with our math, you should find that you will spread approximately 23 pounds in 100 feet. All material is different due to size and density, however, so checking the chart is vital to success.
