GENERAL INFORMATION

Introduction

There are presently 3 variations of the K-71 transaxle
being used.
The K-71E has a differential lock, automatic controlled
traction, and a charge pump that in addition to maintain-
ing the closed loop of oil between the pump and motor,
allows the unit to have hydraulic lift and power steering.
The K-71G has no differential lock, but does have auto-
matic controlled traction, and a charge pump which
allows the unit to have hydraulic lift and power steering.
The K-71J has no differential lock, but does have auto-
matic controlled traction, and a charge pump. The
charge pump in this unit is of a different style and will not
provide hydraulic lift or power steering.
Some unique features of this transmission include:
• An internal wet brake.
• The transaxle case is divided into two sections which
results in a number of benefits. Most particulate
contamination from the gear train is kept away from
the sensitive components of the hydro. The transaxle
case is strengthened, and the unit is quieter in opera-
tion. Oil also gets a chance to cool as it flows
between sections.
• There are three filters in this transaxle. The first is
the main filter within the hydro section that filters the
oil prior to it being circulated through the rotating
groups. The second separates the two sections of
the transmission and keeps particulate contamination
away from the hydro section. The third is the spin on
filter under the seat deck.
