MODELFARMER Posted October 24, 2009 Share Posted October 24, 2009 The reason I ask is we have the AD 303 top Pack drill, (mechanical gravity seed drill) but I wonder what is the advantages of the air drill equivilent?? the AD-P Special/Super 303??? Any comments or experience i'd be grateful Quote Link to comment Share on other sites More sharing options...
Gav836 Posted October 24, 2009 Share Posted October 24, 2009 I'd stick with the box drill myself, we had a RPD402 where I used to work, it has since been replaced with a new one and also a RPD302. They're just so simple, theres sod all to go wrong with them and they do a good job. If you're on hills they are better than a pto driven air drill as with being driven independant of the tractor it makes no difference to seed flow if the revs die down, thats one of the reasons we ran the box drill Quote Link to comment Share on other sites More sharing options...

archbarch Posted October 24, 2009 Share Posted October 24, 2009 yes they do but as revs die so does the air flow, seed rate will be the same its whether you will achieve accuracy across the width of the drill may even block pipes with seed on very steep ground. I havent used an Amazone drill but ive used both types and i would stick with what youve got. Quote Link to comment Share on other sites More sharing options...
