⚠️ Please note that the Spraying While Seeding Kit is:
- only compatible/recommended for 450mm and 500mm row distance. Other distances could cause interference with rear wheels!
- only allowed for seeding position, as there could be interference with rear wheels in weeding position.
It is possible to retrofit the Spray While Seeding Kit on any existing FD20 robot, that has + Spray.
The tools you need for completing the task are:
- 2x 13mm spanner or socket wrench
- 10 mm spanner or socket wrench
- Sidecutter

RETROFITTING PROCEDURE
Throughout the procedure, please handle the +SPRAY tubes with care as they might contain residues of chemicals!
STEP 1 - Dismantle back wheel and console/scraper
Two types of back wheel.
Figure 2 With additional weight bracket: Figure 2 Only 1x M6 bolt+ Nut
Figure 3 Without additional weight bracket: Figure 3 2x M6 bolt+ Nut
Figure 4 Keep wheel, bolt, nut and washer. They need to be mounted again later
STEP 2 - Mount new Rear wheel bracket for spraying
Figure 5 2 x bolts M6x20 + Nuts on the back side (not visible)
If previous back wheel is mounted, with additional weight bracket, use the extra bolt and nut that comes with the "Spray while seeding" kit !
Figure 6 Upper hole (marked with Green arrow) for mounting the back wheel after mounting the new bracket. Be Aware ! There are 2 holes for the wheel to be mounted!. Upper hole is Standard, lower hole (Red Arrow) is for when Shallow seeding cant be reached with normal settings!
STEP 3 - Replace the “Seed cover Plow”
The seed cover plow needs to be changed to a shorter model. The standard, long model will hit the wheel.
Figure 7 Loosen nuts and replace Plow with new short model (comes with the Spray while seeding kit) Reuse bolts and nuts
Figure 8 Change to short model (comes with the Spray while seeding kit) Bolts + Nut to be reused
STEP 4 - Move the nozzle
