Frame Height
Frame height is determined by an adjustable hydraulic
depth control valve, and has a significant effect on
planting depth.
Frame height adjustment methods depend on coulter
configuration. Frame-mounted coulters (FMC) are
standard on some 3N-40 models and optional on others.
The 3N-4010HDP accepts either FMC or unit-mount
coulters (UMC), although only one type of coulter can be
installed simultaneously.
For adjustments:
1. Frame-Mounted Coulters (FMC)
frame height information begins on page 75.
2. Unit-Mounted Coulters (UMC, 10HD and 25P only)
frame height information begins on page 101.
3. No Coulters
use the same frame height setup as UMC, page 101.
Frame Height without
Frame-Mounted Coulters
Use these instructions with a drill having no coulters, or
having unit-mounted coulters (UMC). Adjustments to
individual unit-mounted coulters themselves (10HD
models only) are on page 101.
