Hydraulic Systems – Dynamic Description

The hydraulic system of this tractor utilizes an open-center design powered by an engine-mounted gear hydraulic pump. Sharing a common transmission case reservoir and suction filter, both the hydraulic system and steering pumps ensure synchronized performance.

Key Features

• Engine-mounted gear hydraulic pump for efficient power flow.
• Open-center hydraulic system design.
• PTO solenoid valve block with integrated electric solenoid valve, reduction pressure valve, engagement delay valve, and sequence valve.
• Mid-mount two-spool hydraulic control valve containing the system relief valve.

Benefits

• Enhanced hydraulic system performance through carefully engineered valve blocks.
• Compatibility with optional rear remote valves, available in both single and double spool configurations.
• Seamless flow management to the Hydraulic Power Lift (HPL) system, featuring an adjustable drop rate valve and safety relief valve.

Usage Recommendations

• Ensure regular maintenance of the hydraulic pump and filters for prolonged system efficiency.
• Regularly inspect the PTO solenoid and related valves for optimal functionality.
• Utilize the manual to understand the sequence of hydraulic flow for troubleshooting and repairs.
• For hydrostatic models, maintain the additional HST filter and oil cooler to ensure smooth operation of the hydrostatic transmission.
