Frame Weight
The standard 3S-4000HD/HDF includes 2381 pounds
(1080 kg) of weight bars inside the main tool bar. This,
plus the extra weight of 00HD row units, permits
adjustment of the full range row unit down forces.
If markers are installed, additional force is available.
Although suitcase weight brackets are available for
earlier model 3S-4000/F (non-HD) drills, these weight
kits are not recommended for 3S-4000HD/HDF drills.
