The engine load readout gives the operator a gauge on the percentage of the available engine power being used at any given time. New Holland recommends operating in the 80% to 100% range with a safety margin beyond that for slug feeding. A readout of 100% tells the operator that the engine is at full power at 2100 rpm unboosted.

Operating the CR/CX combine above 100% power will lead to poor performance due to rpm drop, especially if rpms drop for the cleaning system. The combine operates most efficiently when engine rpm is kept at 2100 rpm. If unloading on the go, it will be necessary to reduce ground speed if the engine is already above 100% before engagement of the unloading auger.

Operation above 100% load may actually reduce capacity and will lead to more operator fatigue. Compared to engines on older model combines, the CR/CX engines are electronically managed. Therefore, the operator will not feel or hear the engine pull down as with the older designed mechanically controlled fuel systems.

See your Operator's Manual "Main Info Screen Setup" section for instructions on how to place the percentage of engine load on your harvest screen.

The unique New Holland stone detection system (ASP) uses four sensors, two above the crop and two below. When the system detects a stone, the feeder stops automatically, the operator is notified, the ejection door opens and the rock is ejected. You close the door from the cab.

Here's how to close the ASP stone door after a stone has been detected:

1. Raise the head a few inches and back away from the uncut crop.
2. Push down on the header engagement switch.
3. Reverse the feeder to clear the stone door opening of any crop.
4. Pull the combine forward a few feet to make sure the stone door does not scoop the crop that was just reversed out of the feeder.
5. Without pausing, raise the feeder to its highest position and wait a few seconds to allow the latches to engage the door.
6. Lower the feeder to make sure the door is closed. If the stone door light on the A-post illuminates and A0071-"attempt stone door re-latch" appears on the InfoView™ monitor, the door did not latch. Proceed to step 7. If no messages appear, the door has latched and harvest can continue.
7. Press the emergency stop (red) button on the propulsion handle to retract the latches for another closing cycle.
8. Go to step 3 and repeat as necessary.

The Automatic Crop Settings (ACS) system allows you to store and select machine settings for different crops or harvesting conditions. ACS will then automatically change the machine's settings when the operator indicates that the crop type or harvesting condition has changed.

The operator can indicate that the harvesting conditions have changed by changing ACS modes. There are three ACS modes: two working sets possible per crop and one extra set that will be selected automatically when traversing the headland. (Figure 2.)

Mode 1 and Mode 2 are easily selected using the Mode (or Alternate Settings) switch on the right-hand console. While harvesting in header stubble height or auto float modes, double clicking the "Resume" button raises the header and places the machine in its third mode: Headland mode. When the "Resume" button is pressed a single time to lower the header, Mode 1 or Mode 2 is re-entered depending on the current position of the Mode switch. Each mode can be assigned a different settings type.

There are three settings types: Default (Factory), User, or None (No set). Default settings are the factory or recommended values for a particular crop. User settings are custom values that are specified by the operator. “None” means that the settings will remain unchanged when the crop or ACS mode changes.

There are Default (Factory) settings for 22 specific plus 10 custom crops totaling 32.

User settings can be assigned to any of the 32 crops (However, you are limited to 12 active user settings at any given time.)

You can also make manual adjustments to the machine and save the settings quickly for any crop and mode. When you choose to save your current settings, the type for the selected mode is automatically set to "User". This makes it easy to set the machine up to your liking and then "memorize" the settings. (Figure 3.)

Do the settings have to change when I change modes?

No. If you have individual settings that you want to remain unchanged, define the same value for these settings for the two modes in question. If you don't want any of the settings to change, set the ACS type to "None" and all of the previous settings will remain unchanged. For instance, if you donít want the settings to change in the headlands, set the ACS type to "None" for the Headlands mode.
