FIND A TEDDER FOR YOUR MOWER
The equation below determines which tedder matches the working width of your mower to cover 3 or 5 windrows. It is recommended to cover an odd number of windrows so the tractor wheels do not drive on the forage. This is important for ensuring forage quality, reducing harvesting losses, and above all, for safety on sloping terrain.

A = 2W + S + △
B = 4W + S + △
W – cutter bar working width
S – windrow width
A, B – tedder working width
△ – additional tedder overlapping
Example:
Calculation for a 6-disc mower with a working width of 2.60 m (W) and a windrow width of 1.50 m (S).
A = 2W + S + △
A = 2*2.60 + 1.50 + △
A = 6.70 + △
B = 4W + S + △
B = 4*2.60 + 1.50 + △
B = 11.90 + △
A suitable tedder for a 6-disc mower therefore has a working width of at least 6.70 m. In this case, the ideal tedder would be the SPIDER 685|6 (A) for the overlapping of 3 rows or the SPIDER 1100|10 (B) for the overlapping of 5 rows.
