ASSEMBLY INSTRUCTIONS FOR CNH 1250/1255 PLANTERS (12 & 16 ROW)
WARNING: NEVER WORK UNDER THE EQUIPMENT WHILE IN A RAISED POSITION WITHOUT
USING SAFETY LOCK UPS. FAILURE TO DO SO MAY LEAD TO PERSONAL INJURY OR DEATH.
STEP 1:
Start by placing 2 U-bolts at each row, threads toward the ground, between the U-bolts used to mount that seed unit to
the toolbar (see picture below labeled shim installation). Remove zip ties from planter hydraulic hoses, pneumatic tubing,
electrical cables, and vacuum hoses if needed to make it easier to install the U-bolts. Some rows may require longer U-
bolts. If a pneumatic tank is mounted to the toolbar, it may need repositioned.
NOTE:
Each CNH mount, both LH & RH, will have an indicator arrow (see picture below labeled CNH MOUNT INDICATOR
ARROW) which is the approximate location of where the slot will be to help achieve your desired spacing off the row.
STEP 2:
Start at row 1, standing behind the planter, row 1 is the left most row. Install the 4000-261 LH CNH mount so that
the left side of the mount is up against the left U-bolt that mounts the planter row unit to the toolbar. The left hand
mount will extend forward with the 2 coulter mounting holes offset to the left (see pic below labeled 4000-261).
Tighten the mount down using 5/8 lock washer, 5/8 hex nut, & an impact driver with a 15/16 socket. Install the LH
coulter using 2) ¾ X 2 bolts &2) ¾ lock washers. Tighten the coulter down with an impact using a 1 1/8 socket.
STEP 3:
Next, install the 4000-260 RH CNH mount on the last row of the right wing. Install the RH CNH mount so that the
right side of the mount is up against the right side of the U-bolt that mounts the planter row unit to the toolbar. The
right hand mount will extend forward with 2 coulter mounting holes offset to the right (see pic below). Tighten the
mount down using an impact driver with a 15/16 socket.
STEP 4:
Fold the planter to ensure the 2 coulter units installed have clearance with each other. If interference occurs,
loosen the 4000-260 or 4000-261 mounts to make the proper adjustment for clearance.
