The above photo shows the tractor mounted Amazon cutting and collecting the mown grass land on the right hand side of the 15th hole.
The grass is mown after it has set seed and before it naturally dies back releasing unwanted nutrients into the soil profile. These nutrients promote the wrong type of grasses for a golf course rough. Natural infertile soils help promote the desirable Fescue and Bent species which develop thin whispy swards that are more acceptable for golf. This process is long term managment and will improve the sward year on year. Smaller areas will be strimmed and collected by hand.
