| How many acres do you have on that 750?
I have seen the bottom of the seed tubes wear (to the point they flop over and present seed flow issues on a box drill, especially when working on slopes). When guys replace the boots it straightens them up somewhat (as some of the wear is within the top hole of the seed boot). Replacing the pointed bolt and the seed boot periodically has helped most guys address this seed tube concern however (especially if they tighten up the pivot points on the seed boot with a bushing kit to stop the boot/tube flopping all the time).
The seed tubes themselves are made of a very hard material, so it takes a lot of acres before they need replacement (which is good becuase they are not cheap). I know of a 36' 1850 that has over 100,000 acres and another 30' 1850 that has 80,000 acres, those are what I use for durability testing attachments ! If well maintained and operated, such seeders can still perform to an acceptable standard however.
