Son  in law has just bought a second hand Flexi coil seeder  bin.
Hydraulic driven fan, presurised boxes, infinitely variable seed and super rates.
The question I want to ask other owners is how is the variable drive unit drive attached to the seed and super distribution sectors.
On the box [bought from a dealer] S-I -L  has the drive cog on the variable unit is connected to the seed distribution shaft by a crappy three bolt arangement  that just wobbles around as it turns. To me it looks like the drive shaft on the variable unit does not line up  with the shaft on  the distributoin units.
Could some one please describe what the drive should look like?
TAI.
