This operator's manual is for Valtra T3 Series HiTech tractors. The T3 HiTech models are T133 H, T153 H, T173 H and T193 H. The manual is meant for agricultural tractors only. If the tractor is used for other applications, it is the owner's responsibility to ensure compliance with local regulations. In this case, always contact your dealer first. The purpose of this manual is to enable the owner and operator to use the tractor in a proper manner. Providing that the instructions are followed carefully, the tractor will provide years of service in the tradition of Valtra.
Valtra T3 Series User Manual
Switching off the air conditioning with the air conditioning system on/off button activates the ECO mode. The air cooling compressor is turned off and the system tries to achieve the target temperature by other available means, such as fresh air intake and fan speed.
Activate the air conditioning system to increase the fan speed by pressing the air conditioning system on/off button.
The efficiency of the fan speed can vary when the system tries to maintain the adjusted cab temperature. An increase in the sun heat radiation increases the fan speed.
You can change the driving direction smoothly with the power shuttle lever. The engagement of the power shuttle is automatic. You can request a driving direction change with the power shuttle lever at any driving speed, but the transmission starts to engage the new driving direction only when the speed is below 10 km/h. If the driving speed is higher, the transmission does not automatically start braking until the speed is low enough.The new direction arrow starts to flash to indicate that the driving direction change has been requested, and is lit constantly when the new direction is engaged. If you return the power shuttle lever to the original direction when the driving speed is still over 10 km/h, the traction engages immediately.
When driving with automatic or semiautomatic driving mode, the tractor does not move unless you press the driving pedal.
The operator detector prevents the shuttle engagement if you are not on the seat. If the direction is selected, the arrow of the selected direction flashes on the display panel. The selected direction does not engage until you sit on the seat and move the power shuttle lever to the parking brake position (P) and then to the desired direction.
Select the desired driving direction.
Move the power shuttle lever to the forward (F) or reverse (R) driving direction. Change the driving direction at lower driving speeds with high load so that there is less stress on the power transmission. When driving with automatic or semiautomatic driving mode, the tractor does not move before you press the driving pedal.
Adjusting the power shuttle engagement speed
You can adjust the power shuttle engagement speed through the tractor terminal transmission settings. The index determines how quickly the torque of the power shuttle increases to the maximum value when the clutch is engaged. The index affects both the F (forward) and R (rearward) clutch engagements.
The tractor transmission system has four speed gears and three range gears. In addition, the tractors have 3–step quick-shift gear. These together give the tractor 36 forward and 36 reverse gears. The range gears are named LL, M and H. The range gear LL is called creeper range gear. The actual driving speeds achieved depend on the engine speed and the tyres. The following table includes approximate driving speeds for each speed range with engine speed of 1400–2200 rpm.
Preprogramming gear for driving direction changing
You can preprogram the wanted speed range and Powershift gear to engage automatically when changing driving direction. For example, when working with the front loader and changing the direction to forward, Powershift 1 can be engaged, and when changing the direction to backwards, Powershift 3 can be engaged.
