IVT Selector Guidelines and Examples

RXA0086589


A-Four-Position Switch
B-Position OFF


C-Position 1-PTO


D-Position 2-Heavy Tillage


E-Position 3-Transport or Light Tillage

NOTE: For most applications, maximum productivity and fuel economy is realized when the selector is in positions 1, 2 or 3

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

The IVT selector is a four-position switch (A) 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.

Four-Position IVT Selector Switch
B-Position 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.)
C-Position 1 Most PTO and High Hydraulic flow Applications Use full throttle positionOperating under load: transmission automatically adjusts speed to maintain Heavy Load RPM setting (1950 rpm)Operating under light load : engine speed will be approximately 2000 rpm (Low RPM Default)a
D-Position/Auto 2 Plowing and Tillage Use full throttle positionAdjust Auto 2 set speed to match applicationOperating under load: transmission automatically adjusts to maintain 1950 rpmOperating under light load: minimum engine speed is 1500 rpm
E-Position/Auto 3 Transport and Light Tillage Use full throttle positionAdjust Auto 3 set speed to match applicationOperating under load: transmission automatically adjusts to maintain 1950 rpmOperating under light load: Minimum engine speed is 1200 rpm
