MAIN HYDRAULIC SYSTEM
7.1
Observe all fittings, pipes, tubes, and hoses for leakage. Tighten as needed.
7.2
Observe oil level in main tank. On truck mount or stationary units the dipstick
capacity allowed is 95 liters (25 gallons). For “All Hydraulic Unit” the dipstick
capacity allowed is 284 liters (75 gallons).
7.3
On tractors, the maximum pump capacity required to operate the Bale Wagon is 53
liters per minute (14 gpm) @ 2200 P.S.I. The minimum pump capacity required to
operate the Bale Wagon is 45 liters per minute (12 gpm) @ 2200 P.S.I
7.4
Manifold block specification is 53 liters per minute (14 gpm) @ 3000 P.S.I.
Caution: Do not exceed these limits.
7.5
Manifold relief valve is factory set @ 700 P.S.I. for maximum safety to the system.
7.6
Crossfeed and floor motor specification, maximum 58 liters per minute (15 gpm) @
700 P.S.I... Beater motor specification, maximum 76 liters per minute (20 gpm).
7.7
Crossfeed motor under normal operation requires a minimum of 46 liters per minute
(12 gpm) to a maximum of 53 liters per minute (14 gpm) to provide adequate unload
speed. The speed is controlled through the Crossfeed flow control valve located on
the Bale Wagon.
7.8
Stalling of the Crossfeed motor may be caused by the loss of oil pressure (P.S.I.) to
the motor, due to incorrect adjustment of relief valve or worn pump/ motor.
7.9
Slow speed of Crossfeed or floor motor may be caused by the loss of oil flow from
the pump source to the motor, due to worn pump or restricted flow in the tractor
hydraulic system/hydraulic hoses.
