| 64 openners vs 48 on a 40 foot double disk drill. 32 more bearings and openner disks to replace. As was mentioned earlier, residue flow can be drastically prohibitted by the narrower spacing.
Seems like in advertising periodicals such as Troctorhouse and the like, you see a great deal more late model 7.5 versions of drills than 10 inch. Talking with a dealer who's sold Great Plains and he said the 10 inch models are by far the more popular. The only application I would give preference on a 7.5 inch model would be for drilling 15 inch milo. | |
