- Connect the hydraulic hose (1) on the blower to a
single acting or double acting valve.
- Connect the hydraulic hose (2) of the blower to a free
return on the tractor. If the tractor is not fitted with a
FLAT FACE coupler, use the one supplied with the

return.
After connecting the hoses, check that there is no risk of
catching them during operation.

seeds engaged on the disks.
For a precise measure of the suction value, a
