e)Move lever out of transport (or 5” (12.7 cm) cutting height) position and down onto height adjustment pin to mow at selected height.

f)To transport, move lever back up to transport (or 5” (12.7 cm) cutting height) position.

Note: The foot operated deck lift assist lever can be used to momentarily lift the deck to clear objects. Be sure that PTO is disengaged.

g)Adjust anti-scalp rollers for Normal Operating Conditions. Stop engine, wait for all moving parts to stop, and remove key. Place rollers in one of the positions shown in Figure 10. Rollers will maintain 3/4 in. (19 mm) clearance to the ground to minimize gouging and roller wear or damage.

For Maximum Deck Flotation, place rollers one hole position lower. Rollers should maintain 1/4 in. (6.4 mm) minimum clearance to ground. Do Not adjust rollers to support the deck. Be sure bolt is tightened properly or loss of anti-scalp roller may result.

FOR CUTTING HEIGHTS ABOVE 3.5” (38 mm) USE THE BOTTOM

e)Raise the deck to the 5” (12.7 cm) height position (also transport position) and take all force off of the two large deck lift springs by loosening the nuts at the front of each spring. See Figure 11.

f)For 60” units - Lower the deck to the 1-1/2” (3.81 cm) height position.

For 72” units – Lower the deck to the 1-1/2” (3.81 cm) height position. Force the left rear deck support arm downward about 1/4” (6.4 mm) to get the deck to rest at the 1-1/2” height position. Place locking pliers between the rear swivel and spring stop to hold the deck in this position. See Figure 11.

h)Loosen the two (2) top chain bolts in slots in the rear deck lift arms. Loosen jam nuts and back off the socket head adjusting screws on the bottom of the arms until the chains are just loose. Turn the socket head adjusting screws in until slack is taken out of each chain. Tighten the jam nuts. Tighten the chain bolts in the deck lift arms making sure they don’t move while tightening.
