Introduction

Engine to Transmission Coupler (Fig. 1)
Engine power is transmitted from the engine through a
flexible coupling and drive link to the hydrostatic trans-
mission. With this Toro design, there is no clutch used
between the engine and the transmission.
The drive coupling consists of three main components:
a metal drive coupling (shaft), a rubber coupling bolted
to each end of the shaft, and the pump hub.
PTO System (Fig. 1)
The power take-off (PTO) system transmits power from
the engine to the cutting deck or other implement at-
tached to the from of the machine.
The PTO lever has two positions: ON (engage) and OFF
(disengage). To engage the PTO shaft, slowly push the
Introduction
PTO lever fully forward to the ON position; this will start
the implement or cutting unit blades. Slowly pull the
lever backward to the OFF position to stop the imple-
ment's operation. The only time the PTO lever should
be in the ON position is when the implement or cutting
unit is down in the operating position and the operator
is in the seat.
Do not start the engine and engage the P.T.O.
lever when the P.T.O. shaft is not connected
to the gearbox on the cutting unit or other
implement. If the engine is started and the
P.T.O. shaft Is allowed to rotate, serious In ury
could result.
