flat terrain. If scalping occurs or the cut is uneven from side to side, there may be too much weight on the deck and the weight may have to be transferred to the machine: i.e. increased counterbalance pressure. By contrast, if too much weight is transferred to the machine, the deck will bounce excessively and the cut will be uneven. - Page 20 Figure 13 1. Lift valve 3. Jam nut 2. Counterbalance valve 4.

Hydraulic Lift Lever The hydraulic lift lever (Figure 19) has three lever positions that actuate four operating modes; LIFT, LOWER, FLOAT & HOLD. To lower the deck, in preparation for mowing, move the lever forward and then allow the lever to freely return. This will allow the deck to drop at a controlled rate and enables the deck ground following float function. -
