750A seed boot bolts

[Howdenshire Farmer]

do you mind me asking where you got these bushings?
i ordered new coulters and bolts with part numbers off jd parts and it never crossed my mind that there could/would be different coulters/bolts.
just for reference for anyone going to re-metal their drill, coulters with 7/16 holes are N284044(rh) and N284045 (lh). 3/8 are N280446 rh and N280447 lh. @Howdenshire Farmer

The 3/8 to 7/16 bushes came from a company called Simply Bearings who I found online.
As far as I am aware all 90 series coulters are on the bigger 7/16 bolts. I think the 5/8 are from quite old machines now but definitely worth confirming which size if they predate the 90 series.

Could always try these...

Has anyone used these, they look cool and I like the lack of drilling out related ballacheage

I emailed them about a price once. They were reasonable sort of. But the freight was astronomical considering theres nothing of them.
