Hydraulics

Hydraulic controls on Versu and Direct tractors

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

The maximum hydraulics output of 115 l/min is extremely high, and even 160 l/min is optionally available on Versu and Direct models. The output can be programmed according to flow and timing. Valtra’s load-sensing hydraulics meet all the requirements of the newest implements and implement combinations.

Work hydraulic valves:

• On Versu and Direct models up to 5 fully programmable valves and 2 ON/OFF valves at the rear
• 2 or 3 valves available at the front
• Standard ON/OFF valve controls quick coupling and optional ON/OFF valve is connected directly to the implement
• Power Beyond couplings can be fi tted to rear for maximum output

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 or front linkage. The linear switches in the armrest are used to control valves 3, 4 and 5. The number of control switches varies according to model.

Hydraulics on Classic and Hitech models

On these models the hydraulics are controlled by switches located on the right-hand panel. The hydraulic output is 73 litres per minute. Four valves are available.

A flow control valve on the fi rst valve is available as an option. Two valves are available for controlling the front loader and front implement. These valves are controlled electronically from the driver’s armrest. The optional front linkage is controlled using valve 3.

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, while for Versu and Direct models they are located in the driver’s armrest. Drive Balance Control comes as standard with the linkage. Autocontrol combined with wheel slip control is standard on the Versu and Direct models.

1. Autocontrol lift and lower switch
2. 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

Drive balance control

Drive Balance Control is a standard feature of Autocontrol. When engaged, this system works like a shock absorber when carrying heavy implements on the linkage over uneven ground. The system senses the variations in dynamic loading and automatically makes corrections to even out the bumps.

Drive Balance Control operates only in the transport position. The system begins to work when the factory adjusted 8 km/h limit is exceeded. The limit is adjustable in Autocontrol ACD; in ACB the function starts as soon as the tractor is moving.

Benefits:

• Driving the tractor is more even and stable
• Improves the ground contact of front wheels for safer steering
• Reduces high stress loads imposed by heavy implements in transport

U-Pilot (Versu, Direct)

Valtra’s U-Pilot Headland Management System significantly reduces the amount of work needed to turn around repeatedly in the headland. This helps to keep the driver more alert and makes turning around faster. The system also reduces the risk of human error when managing so many functions. The Off/On/Rec switch is situated in the B pillar, while the Start/Stop switch is in the driver’s armrest. The display is in the instrument cluster.

Tractor operations controlled by U-Pilot:

• three-point linkage
• two ancillary hydraulics valves (3 and 4)
• 4WD
• differential lock
• PTO (front/rear)
• cruise control
• Powershift
• DIN electrical connectors

A pause can also be programmed into the system. When storing the programme, the distance travelled by the tractor is registered, according to which the operations are timed.
