Why change weeding tools - Weeding knives - Weeding wires
Most of the hours spent in the field by your FD20 are going to be for one operation: weeding.
Using highly-worn or damaged weeding knives and wires is useless under the weed-control point of view. Using damaged or worn tools will increase the weed pressure and reduce the expected yield. Therefore, it is only in your interest to maintain properly the weeding tools.
It is difficult to explain in few words when the weeding knives and wires should be replaced, as the best advice possible it to observe the robot during daily operations and determine if any of the tools is not working as it should due to wear.
Down here, you can find a table with some examples of tools that worn out, to help you determine whether the parts should be replaced or not.
WEEDING KNIVES
Weeding wires get thinner and thinner as they work in the field, depending on the amount of hours the robot spends in the field and on soil texture.
They normally would not bend, so they should be replaced when they are too short to cover the area you want them to sweep.
New conditions | |
Almost new conditions | |
Starting to get worn, can consider to replace in a short while | |
Worn, this knife should be replaced as it cannot sweep the whole weeded area | |
Extremely worn, this knife is not able to cover the weeded area and should be replaced as soon as possible | |
Completely worn, using this knife is just a loss of time as it won't be able to remove any single weed |
WEEDING WIRES
Similarly to the knives, also the weeding wires get thinner as they work in the field, depending on the amount of hours the robot spends in the field and on soil texture. However, as they get thinner, they can also bend.
Straighten a bended weeding wire is not a problem if the metal wire is thick enough.
We recommend to replace the weeding wires when the they get too thinned to be straightened again or when they have been permanently damaged (e.g. missing a side).

Used but in nearly new conditions | |
Slighly bended. Can be straighten and used with success | |
Bended, but can be straightened if the wire is thick enough | |
Completely bended wire. When they get so bent, it's because of the metal wire has worn out too much and, for this reason, they should be replaced | |
Completely bended. This weeding wire should have been replaced long ago. It is completely useless as it is |
Replace the weeding knives and wires on time and get all those weeds out of the ground! 😀👇
