Cutting Unit Drive: Gear box mounted on cutting unit is driven by PTO shaft, Power is transmitted to the blades by three B section belts.
SET-UP INSTRUCTIONS 3. Slide spacers onto caster spindle to get desired height-of-cut: refer to Height-of-Cut Chart, page 10 Slide thrust washer onto spindle, push large caster spindle through front caster arm and small caster spindle through rear caster arrant, install remaining spacers onto spindle and install lynch pin to secure assembly (Fig. 1, 2}, Figure 1 1. Lynch pin 3. Th east washer 2. Spacers 4.
SET-UP INSTRUCTIONS 4. Position Belly Shield mounting hooks over hub of push arm mounting brackets {Fig. b}, Figure 5 1. Befit shield mounting hooks 5.

SET-UP INSTRUCTIONS 7. Raise front of lift arm until hole in movable end of cylinder fines up with holes in §ift arm brackets. Use caution as lift earn is spring-loaded. Hold parts together with cylinder pin, spring pin, and WARNING cotter pin. Cotter pin must be to the outside. Since the right hand push arm is spring toadied to about 100 pounds (445 M), a helper is beaded to push the push arm down. Sudden reseals of the push arm could cause injury, 3.
SET-UP INSTRUCTIONS PP A WARNING Since left hand push arm is spring loaded to about 150 pounds (667 N) a helper is needed to push down on-the push arm, Sudden release of the push arm could cause injury. 2. Have a helper carefully push down on the push arm until ball joint mount contacts front of mount bracket on cutting unit. Immediately slide {102 x 102 mm) block of wood between top of push arm and underside of chassis. A Make sure the wooden block does not slip out accidentally.
SET-UP INSTRUCTIONS GREASE CUTTING UNIT Before the machine is operated, it must be greased 1o assure proper lubricating characteristics: refer e Lubrication, page 12. Failure to grease the machine will result in premature failure of derivative parts. 1. PO shield 4. Spring in dth link 2.
