A Series Quick Guide / HiTech
Valtra A series transmission has
12 + 12 gears in two working ranges.
Having 6 gears in one working range
minimizes the need of two gear lever
changes when working.
Optional Super Creeper available when
the slowest speeds are required down
to 140 m/h* or even to 90 m/h**,
making the transmission 24 + 24 gears
with excellent overlapping over the
gears. See the example of the available
speeds.
In HiTech models you can change the driving
direction without using the clutch pedal. Just use
the power Shuttle lever under the steeting wheel. You
can also use clutch pedal if you prefer.
* at 1400 rev/min with 16.9R34 tyres (Small)
** at 1400 rev/min with 18.4R38 tyres (Large)

2 Oil level gage
3 Leakage oil reservoir for the quick
couplings
Before starting the tractor, please make sure that daily
maintenance checks are done. Daily maintenance check
points are:
1.
Check the engine oil from dip stick
Engine oil stick is situated on the right side of the engine.
Make sure that engine oli level is between the lower and upper mark.
If necessary, add oil through the oil ller cap.
2.
Check coolant level
Make sure that the coolant level in the coolant expansion tank is above the
uid level mark for cold uid. Coolant expansion tank is located under the
engine hood
3. Visual check: tyres, oil leaks, radiators.
Clean front grill & radiators if needed.
4.
Check oil level in the transmission and hydraulic system
The oil level must be between the minimum and maximum lines of the oil
level gage. Gage is located at the rear of the tractor, next to PTO shaft. If
the leakage oil reservoir for the quick couplings is full, remove the oil and
discard it.
5. Check Fuel and AdBlue levels
