Fendt CVT at a glance

TRANSMISSION


Facilities 50kph top speed. Engine/transmission control now integrated by switchable TMS system. Basic (joystick) or pedal driving as required. Separate road/field speed ranges.


Controls Joystick with enable button, cruise control and direction shuttle functions. Separate tab switch by steering column for direction shuttle. Pedal/basic mode selector in armrest, together with slider to vary response in pedal mode. Separate selector on joystick varies response in basic mode. Engine load control and two cruise memory settings accessed only through the Varioterminal.


UNDERSTANDABILITY


First level Depends on mode left by last driver. If left in stick mode, find activation switch behind joystick then drive like stepless powershift. If left in pedal mode, just select travel direction and push drive pedal to move off.


Second level Deep diving is complicated. Must know about (and invoke) TMS to unleash powerful engine/transmission integration, and find mode button (hidden behind joystick) to transfer driving control to the floor pedal. Have to locate engine load control among Varioterminal screens and engage individual cruise memories from console pushpads. Must also remember that left joystick flick changes shuttle direction, right flick engages selected cruise memory.


GOOD NEWS


Transmission remembers last mode used when engine switched off. Good for experienced driver, less so for novice


Very handy, obvious slider in armrest gives very wide response control; useful in low-speed fieldwork or traffic


Varioterminal display visually much clearer than Massey’s tiny dash panels


Transmission is geared for 65kph though speed limited to 50kph. So eco mode can allow very generous rpm drop in transport, automatically adjusting (where load allows) to give 50kph at 1550rpm


Management’s extensive control of engine revs also lets revs drop right back as load lifts in fieldwork, so headland turns can be very calm


Can programme different forward and reverse speeds


Can increase engine braking by pulling back joystick without dropping out of pedal mode


Can switch between pedal and stick modes on the move


Can switch from road to field range at low speed


BAD NEWS


Joystick still ugly, uncomfortable to hold


Varioterminal takes several seconds to fire up after engine starts


Must remember to change ranges between field and road for best efficiency. No obvious wrong-range clue as with conventional gearbox


Vital button for TMS system too inconspicuous


Many turns of Varioterminal knob needed to change engine load control setting – too slow


Tab switch on steering column stalk far less satisfactory than a conventional shuttle lever


Mode switch hidden behind joystick


Hunts slightly for speed under load in full eco mode


No safety interlock in seat, so in pedal driving mode can accidentally move tractor when leaving by offside door


SPRAYING/SPREADING SIMULATION


Fix pto revs in Varioterminal, then control forward speed independently on the joystick or through cruise control.


FORAGING/BALING SIMULATION


As above, with the option of switching to pedal mode for forward speed control if both hands busy elsewhere.
