Level Frame Front to Rear
Level the drill front-to-rear with eye bolts located on the
rear axle only.
6. Repeat the steps “
page 142 using only the rear cylinders, until the drill
is level front-to-rear when drilling in actual seeding
conditions.
When drill is level, opener bodies are at level or
slightly higher at rear.
Drill must be level front to rear in actual planting use
or row plugging will occur. Adjusting wheel depth
stop too low or excess opener spring force can
cause the front of drill to roll forward when planting.
Conventional till ground can also cause drill to run
low in the front if wheel depth is set too low.
7. Have an assistant check front to rear level while
planting by observing the drill from a safe distance.
Drill should run with box and frame level or slightly
lower in the front.
Box Alignment
To check and adjust box alignment:
1. Unfold drill (“
” on page 27) and
place a block ahead of each wing caster wheel. Pull
drill forward against blocks to rock frames back. Pull
forward until stop bolts are firmly against tool bars.
2. Check for proper alignment by running a string line
across back of drill toward outer ends of wings. For
proper alignment, outside ends of boxes
(dimension
) should be 0 to
1
/
4
inches (0 to 6 mm)
ahead of inside ends (dimension
).
