Hydraulics

Load-sensing hydraulics

The work hydraulics are controlled conveniently and efficiently using the joystick and push buttons located on the new ergonomic armrest. The joystick can also be used to control the front loader. Due to the sensitive joystick controls and electronically controlled hydraulic valves, tractor and implement functions can be adjusted with extreme precision.

The load-sensing hydraulics meet all the requirements of the newest implements and implement combinations. The fact that the work hydraulics can be 100% electronically controlled is unique.

The maximum number of valves rear is 4 and 2 on/off valves. In the front  2 or 3 valves for front loader or front lift.

The valves use only the exact amount of fluid as needed, leaving the remaining fluid to be used by other valves or the linkage. This allows for simultaneous operations as required by modern implements. All valves feature a floating position, which allows implements that follow the ground to perform ideally.

To ensure the highest possible output for implements, a Power Beyond connection can be fitted to the rear.

Safety and comfort are further enhanced by the control button for the hydraulics that is located in the armrest:

1. Flow adjusted for small output
   - testing
2. Flow adjusted for medium output
3. Flow adjusted for maximum output
4. Adjustment position
   - 3 memory locations

Ancillary hydraulics valves:

• Standard 2 and one on/off valve
• Optional 2 or 3 ancillary hydraulics valves to the rear, plus one on/off valve.
• 2 or 3 valves available to the front (customer can choose)
• Maximum number of valves to the rear is 5 + 2 on/off valves, and to the front 3 valves for using a front loader or linkage.

The standard on-off valve is used via the quick couplings, and the optional on/off valve is piped directly to the implement.

The load sensing system allows the valve to supply only the amount of oil demanded by the implement leaving the remaining fluid to be used by other valves or the linkage. This allows for simultaneous operation of valves and linkage as required by the latest modern implements. All valves feature a float position to work with implements that follow the ground contours.

To ensure the highest possible output for implements, a Power Beyond connection can be fitted to the system at the rear.

New armrest

The joystick on the driver’s armrest is used for controlling valves 1 and 2 of the ancillary hydraulics and may also be used to operate the front loader. Most of the ancillary hydraulic system can be activated using the armrest’s joystick, switches and buttons. The switches and buttons for the remaining system are situated in the side panel. The linear switches in the armrest are used to control valves 3 and 4.

Mechanical hydraulics control on Classic and HiTech models

In Classic and HiTech models, the ancillary hydraulics are controlled by levers located on the righthand panel. The hydraulic output is 73 litres per minute. Two valves come as standard with a third and fourth as an option.

Valtra Autocontrol

Operating Valtra’s electronically controlled Autocontrol linkage is easy and all operations can be carried out from inside the cab. The switches and buttons for Classic and HiTech models are located in the side panel. Drive Balance Control comes as standard with the linkage. Autocontrol plus wheel slip control, as a combination, is optional.

1. Autocontrol lift and lower switch.
2. Position control/working depth (Classic & HiTech). Position of lower links, including a float position.
3. Dump switch. Temporary position control override.
4. Linkage lift with raise, lower and neutral.
5. Control of speed of lowering the links.
6. Control of maximum height of links.
7. Control for position control and draft control.
8. Drive Balance Control.
9. Slip Control ACD on/off (optional).
