Buhler 2335, 2425, 2290, 2375, 2360 manual Operation

SECTION 2 - OPERATION

The “+/–(SET)” button will change the setting 10 RPM per momentary push. When the button is held down, the RPM will continue to move up or down. However, the dash RPM display will not keep up with RPM changes when the button is held down. In this case, it is advisable to estimate the setting by ear, wait for the dash to catch up, and fine tune the RPM using momentary pushes. It is never possible to set the cruise higher than the current throttle lever position.

If the last cruise setting was above the throttle position, the system will remember that cruise setting unless the “+/–(SET)” button is pressed in cruise mode. The cruise RPM will return to the stored cruise setting if the throttle is moved above that RPM.

The electronic system remembers the current cruise control setting at all times. The cruise setting remains in memory after the cruise switch is turned off, after the engine is shut off, or if the batteries are disconnected.

Alternate Engine Speed Overrun - All N14 engines in 2360 and 2425 tractors have a rated engine speed of 2100 RPM. Actual high engine speed, when the throttle lever is placed in the full forward position, is 2225 +/-- 50 RPM. The difference between the rated speed and the actual full throttle speed (125 RPM) is called throttle overrun (or sometimes referred to as high speed droop). The 125 RPM results in a 6% overrun (125 RPM ⎟ by 2225 RPM = 0.06 x 100%) of the engine in normal loaded operating conditions when tractor ground speed is below approximately 18.5 KPH (11.5 MPH).

In situations where engine load is minimal and tractor ground speed is high above 18.5 KPH (above 11.5 MPH), the Electronic Engine Control System will progress to an alternate engine speed overrun condition. The full throttle overrun will now be 15% (2450 +/-- 50 RPM) instead of the normal 6% (2225 +/-- 50 RPM). An example of this would be a tractor traveling at

12.9KPH (8 MPH), over the road, with the throttle lever fully forward and the cruise switch in the OFF position. Maximum engine RPM shown on the EICS of the tractor will be 2225 +/-- 50 RPM. If the transmission is shifted into a higher gear and ground speed increases above

18.5KPH (11.5 MPH), the engine will accelerate to a new higher speed, with the EICS now displaying a maximum engine speed of 2450 +/-- 50 RPM.

The alternative engine speed overrun feature of the electronic engine controls provide a higher ground speed when traveling over the road with the tractor.

If tractor ground speed is reduced below 18.5 KPH (11.5 MPH), the system will revert to the 6% normal overrun mode.

IMPORTANT: Loads placed on the engine while roading (implements, road grade) will affect tractor ground speed and the alternate speed overrun feature.
