[QUOTE="ploughman1963, post: 5550620, member: 165"] We had a 750A on demo yesterday - got to be careul what I say as it wouldnt be difficult to work out where from. Drilling wheat into sprayed off grass - loads of seed sitting on top of the ground and slots not closed. Seed was going in at 1". Coulters about 1/4" / 1/2" off ground surface. Demonstrator set fan speed at over 3000 and said couldnt be lowered as tubes would block. Well, I tried to talk this through and sumised that seed was either bouncing or too much wind? In the end i insisted we tried lowering fan speed and saw an immediate effect. Without further consulting we dropped fan speed to around 2500 rpm and got the seed loss to an 'acceptable' level. Could we/should we have gone lower? I guess fitting bleed valves/exhaust would be the way forward? Side press wheels were i middle setting - I insisted we move to the top setting and the slot closure was much better. Demonstrator suggested a follow up with a flat roll today would help close the slots :unsure: Did we diagnose correctly, make the right changes? What else should we have done? [/QUOTE]
