Weight Transfer Spring Adjustment

Weight transfer springs are assembled from the factory to apply the maximum amount of weight onto the drive wheels. This setting provides the greatest amount of traction. Some conditions may require the rear wheel lift to be reduced. This can be done by reducing the amount to weight transfer, which will increase the amount of weight on the front and rear casters.

1.Rotate the left motion control arm up and into the operation position.

2.Locate and loosen the knob under the rear of the left fender (see Figure 15).

3.Slide the fender forward and twist upward and outward to remove.

4.To adjust the weight transfer springs, fold the mower deck and front frame and lock in service position. See Deck Manual for complete instructions.

WARNING

Weight transfer springs may have stored energy. Removing the weight transfer springs without releasing the stored energy can cause serious injury.

Fold mower deck and front frame and lock in service position to remove spring tension and release stored energy before performing any maintenance or adjustments on the weight transfer springs. (See Deck Manual for Deck Raising instructions).

5.Remove the retaining ring and washer at either end of the weight transfer spring that retains it to the transfer bellcrank pins and/or weight transfer spring anchor pins (see Figure 16).

6.Pull the spring off of front or rear pin and re-install in the outer hole, to reduce the spring force. Re-install the washer and retaining ring.
