[QUOTE="Simon Chiles, post: 1878930, member: 1233"] They have, it's just the changes were subtle. They have gone through three series of openers, the opener spring was modified to have some free float in it to enable the drill to work in cultivated seed beds. The Gauge wheel has more bolts in it now and is half plastic to grip the central bearing better. The RID tyres had their cleaning lip reduced from 11mm to 7mm to make them last much longer ( loosing the lip is not much of a problem now). They increased the hardness of the disc which has improved wear rates dramatically. The press wheel has gone from a wide one to a v shaped one to help improve slot closure. The closing wheel spring has had about 4 versions, the last type design has reduced it becoming coil bound and therefore increased their life. The seed boot has had three versions, the latest one sits further back in the shadow of the disc and reduces side wall compaction of the slot as well as having better wear rates. The press wheel bearings have been improved and last much longer than the original ones. Coupled with all the above the frames have been strengthened where the old ones used to crack and the metering unit software has had several versions, the latest version being capable of VR. I'd freely admit that you have to be a bit of a nurd to appreciate all the mods but I think it's testament to the original design that the changes were actually only slight and that the other manufactures are now making drills that copy it as close as they dare without infringing patents ( the problem with that is they still haven't got some of the finer points that actually make a difference ).
