IVT™/AutoPowr™ Selector Guidelines and Examples

NOTE: For most applications, maximum productivity and fuel economy is realized when modes 1, 2 or 3 are selected.

RXA0103941-UN-24JUL09

RXA0104049-UN-22JUL09

A - OFF

B - PTO Mode

C - Auto Mode 2—Heavy Tillage

D - Auto Mode 3—Transport or Light Tillage

Minimum engine speed values of modes 1, 2, or 3 are adjustable. See Setting IVT/AutoPowr Options in this section.

IVT (Infinitely Variable Transmission)™/AutoPowr™ has four modes providing two automated productivity functions:

• Load control provides automatic transmission ground speed adjustment under load to maintain constant peak power levels and maximum productivity.
• Fuel economy function provides constant vehicle speed at reduced engine speed in light load or no-load conditions.

IVT/AutoPowr Modes
A-OFF	Transmission will not shift automatically to maintain engine rpm with varying loads	Use OFF position if application is causing undesired automatic shifting. Use OFF position when operating on steep and/or slippery downhill slopes. (See Downhill Operation in Slippery Conditions in this section.) Load control function OFF Fuel economy function OFF
B-Auto Mode 1	Most PTO and High Hydraulic flow Applications	Load control function ON * Fuel economy function OFF Using correct engine speed is very important for PTO operations. Field Cruise may be used to limit engine speed. Refer to implement Operator's Manual for specific implement speeds Approximately 1800 engine rpm equals 540 PTO rpm Approximately 2000 engine rpm equals 1000 PTO rpm
C-Auto Mode 2	Plowing and Tillage	Use full throttle position Adjust Auto 2 set speed to match application Load control function ON * Fuel economy function ON **
D-Auto Mode 3	Transport and Light Tillage	Use full throttle position Adjust Auto 3 set speed to match application Load control function ON * Fuel economy function ON **
