Drop axle assemblies
The drop axle assemblies on the IVT transmission
perform three functions:
• The drop axle assemblies are a gearbox that will
transmit the power of the IVT at a reduced speed
to the drive wheels.
• The drop axle contains a dog clutch assembly to
disconnect the transmission from the drive
wheel. This allowing the tractor to be pushed by
hand.
The drop axle assemblies are serviceable, sepa-
rately from the IVT.
To remove the drop axles:
1. Remove transmission assembly from the tractor
by following the procedures described in the pre-
vious section of this chapter.
2. Remove the eight screws the secure the trans-
mission support bracket to the drop axles using
a 1/2” wrench. See Figure 5B.29
