Frame Weight
The standard CTA4000HD includes four weight kits on
the center frame. Each kit consists of one pair of
700 pound (318 kg) weights, for an implement total of
5600 lbs (2540 kg). This is the maximum allowed. Install
no additional weights.
This extra weight is necessary for opener down-force
settings which, when summed for all rows, are near or
above the total weight of the implement.
In unusually soft soil conditions, remove weights to
reduce weight on the tires. Remove the weights in pairs,
from symmetrical locations about implement centerline.
The weights are held in place by gravity, and are easily
removed with a hoist rated for at least 700 pounds
(318 kg).
Tipping Hazard: Never add weights to the wings. The weights
will tip over during folding. Even if secured to the frame,
machine damage is likely. Wing weights are also unnecessary.
The hydraulic weight transfer system is capable of transferring
the entire weight of the implement to the wings.
