Most field managers, on the other hand, have thatch problems that they don’t deal with as often as they should – mostly because it’s expensive – and their fields usually show it.
Yes, dethatching machines are expensive to buy or rent. So think outside the box: what machine is readily available for rent and will remove 7-8’wide swaths of thatch in a single pass?
A power street broom with a rotary brush!
Sweeping thatch away
The brush will easily remove the thatch if the operator holds it up and allows only the tips of the broom to hit the surface. The loose material is windrowed for easy pickup and a field can be cleaned quickly. It may be used in a similar manner to remove acorns, walnuts, etc.
Most first-timers experience a small learning curve regarding the travel speed of the machine vs. the engine speed and brush RPM.
Two or three windrows may be rolled together to make removal easier. The windrows may be carefully scooped with a light tractor with front bucket or hand removed; the broom will groom the area under the windrow after removal to make the appearance consistent with the other areas of the field.
Removing silt after flooding
In the event that a field is flooded and silt is left on the turf, the same type broom may be used to sweep the silt out of the grass. This has been done successfully, even though the silt was 4” deep over the grass. The power broom will leave the grass intact while making the silt removal much easier.
