im not sure, what is a 2 speed box?Yea no bother it should all be in the book for settings, have you got the two speed spinner box?
oh ok, mine doesnt have that. it does have a second stub shaft but it makes the discs spin in reverse.On your spinner box there can be an alternative stub shaft to attach the pto drive shaft to giving you a faster disc speed
yea 100% sureAre you sure that is not the high speed shaft?
