NOTE:
Drive train protection system only affects operations in gears with maximum operating speeds below 7 km/h (4.4 mph).
When tractor is loaded to a very low engine speed, the PowerShift transmission may default to NEUTRAL, then PARK will engage once wheel speed drops below 4 km/h (2.5 mph) for drivetrain protection.
To engage transmission, move PowerShift transmission lever to PARK, reduce load, and then shift back into desired operating gear.
A PTP Diagnostic code will be stored and displayed when this condition occurs.
The drivetrain protection system is gear-sensitive and will not be apparent in most situations. It does not affect load starting and only affects operations in gears with maximum operating speeds below 7 km/h (4.4 mph). Full engine horsepower, plus 10 percent power

bulge is available in all other gears. With proper ballast, 4WD tractor is traction limited not power limited, at slow ground speeds.
Electronic engine controls provide protection from drive train overloading. Engine horsepower is automatically reduced to protect drive train components when:
-
Air Filter Restriction Warning is activated (CCU 000107.00) the engine performance will be reduced. Service engine air filter immediately.
-
Fuel filter(s) become plugged resulting in a loss of power due to a reduction in delivered fuel. Service engine fuel filter immediately.
-
Using a three-point hitch whenever hitch is not in transport lock position, power is limited to 317 kW (425 hp)
-
Using PTO when tractor ground speed is less than 0.5 km/h (0.3 mph), power is limited to 280 kW (375 hp)
