[4] ECO 40 km/h FUNCTION

(1) Range Gear (6th) Switch
(2) Tractor ECU
(3) Engine ECU
 Travel Speed Limiter (ECO 40 km/h)
With the 6-speed main gear shift type, the highest travel speed is reachable when the engine rpm is at around
the middle level with the maximum travel speed range. This provides for a fuel-efficient run while traveling along
roads, pulling a trailer, etc. Step on the foot throttle, and the engine rpm rises proportionally and the travel speed goes
up accordingly. But the engine speed is limited to 1960 min
throttle is increased. When the main gear shift lever is set to the High-6th position, the Rev-Limiter indicator
illuminates.
This figure is "Travel Speed Limiter" mechanism.
This mechanism is controlled by the Tractor ECU, the range gear shift (Hi) switch, the main gear shift (6th) switch,
the shuttle revolution sensor and the engine ECU. The tractor ECU checks in condition of 6th (main) and high (sub).
The range gear shift (Hi) switch and range gear shift (6th) switch are normal close. When sub range shift (6th) gear
is changed from 5th position to 6th position, the switch opens. After that, when the tractor exceeds 40 km/h, the tractor
ECU communicates the engine ECU to be limited the engine rpm (1960 min
When the tractor becomes out of condition, this feature releases.
Even if one of each sensor is gone wrong, the tractor never extends 40 km/h in any condition. This function is fault
safe.
