PREPARATION AND SETUP

DR12x2 Row Hopper Planter OM-EN 

4-4

Implement-to-Tractor 

Connection

The DR12x2 Row Hopper Planter features a dual-mount 
hitch to dictate whether using twin row or single row 
operation. As part of the unique dual-mount hitch, the 
hitch top link has two mounting locations for the tractor 
3-point hitch. For more information, see “Hitch Pin 
Position” on page 4-11.

See the tractor operator’s manual for more information 
on properly connecting the implement.

The tractor’s hydraulic system must be able to support 
3000 psi (207 bar) of working pressure, and have a 
minimum 2250 psi (155 bar). The hydraulic system 
capacity should be 2 gal (7.5 L) minimum. 

DANGER

!

Avoid crushing. Failure to follow this information will 
result in death or serious injury. Make sure all personnel 
are clear of the implement before lowering.

DANGER

!

Avoid crushing. Failure to follow this information will 
result in death or serious injury. Do not stand between 
the tractor and implement when connecting or 
disconnecting the implement.

1. Back up tractor to the implement hitch. Place the 

tractor in park, turn off the engine, and remove the 
key before connecting the implement. Injury or death 
can result from being trapped between the tractor 
and implement.

2. Set tractor’s three-point hitch lift links. Hitch lift links 

should be adjusted to the operating depth 
dimensions indicated in the tractor operator’s 
manual. 

3. Set tractor’s three-point hitch lateral float pins. 

Lateral float pins should be placed in the lower holes 
to allow machine to “float” and follow the ground 
surface.

4. Set tractor’s three-point hitch sway blocks. Sway 

blocks and bumpers should be installed if no 
implement guidance is being utilized with machine.

5. Connect the tractor’s lower three-point hitch points 

(1) to the lower hitch tug pins (2) on the implement.

6. Adjust the tractor’s upper three-point hitch point (3) 

as necessary to connect the hitch point to the upper 
hitch pin (4) on the implement.

Figure 4-2:  Single Row Planting Hitch Pin Position

NOTE: 

Single row planting hitch position is shown. For 

twin row planting hitch position, see “Hitch Pin 
Position” on page 4-11.

DANGER

!

Avoid high-pressure fluid hazards. Failure to follow this 
information will result in death or serious injury. Relieve 
hydraulic pressure before servicing or disconnecting 
hoses.

7. Relieve hydraulic system pressure before connecting 

the tractor. Attach hydraulic hoses to the tractor 
according to the operator preferences.

8. Attach toolbar controller electrical connections and 

toolbar safety lights to the tractor.

9. Make sure all electrical and hydraulic lines are 

plumbed over the hitch to the tractor to avoid wear or 
damage.

10. Raise bar stands to highest point and install stay 

pins.
