5-1 BASIC MACHINE ASSEMBLY

CAUTON

BASE UNIT IS EXTREMELY TOP HEAVY WHEN DISCONNECTED FROM CUTTER DECK AND SHOULD BE MOVED ONLY BY CONNECTING TO TRACTOR 3-POINT HITCH. DO NOT REMOVE WOODEN SUPPORT UNLESS UNIT IS CONNECTED TO TRACTOR 3-POINT HITCH OR OVER- TURNING WILL RESULT.

A. Connect base unit to tractor 3-point hitch. B. Remove wooden support.

C. With cutter deck flat on ground, connect it to base unit using pivot pin, two washers and roll pins.

D. Connect lift linkage to cutter deck with pin and

roll pins. It may be necessary to remove cylinder port caps to extend cylinder. With port caps removed, watch out for oil spraying out of cylinder ports.

E. Remove cover plate and gasket from spindle housing on cutter deck. Remove O-ring gasket packed inside spindle housing and retain for motor installation.

F. Fill spindle housing with 26 fl. oz. of EP80W- 90 gear oil or until oil reaches check plug.

G. Mount hydraulic motor to spindle housing using O-ring gasket to seal. Fasten with nuts, bolts and lockwashers removed from cover plate.

H. Assemble hydraulic valve kit (Fig. 5-1) or tractor kit (Fig. 5-2). Use pipe joint compound on pipe fit- tings only. Do not use thread tape. Do not over- tighten fittings.

I. Check hydraulic oil level. Fill as needed to bring oil level to bottom of filler strainer. See paragraph 4- 3 for compatible hydraulic oils.
