Separating Cutting Unit From Traction Unit; Servicing The Bushings In The Castor Arms - Toro 30555 Operator's Manual

Separating the Cutting Unit
from the Traction Unit
1. Position the machine on a level surface, raise the cutting
unit, engage the parking brake, put the traction pedal in
neutral, the PTO lever in the Off position, shut the
engine off, and remove the ignition key.
Caution
On the Groundsmaster 200 Series, the
counterbalance spring is in tension when the deck
is in the lowered position.
Always raise the deck before adjusting or
removing the spring.
2. On the Groundsmaster 200 Series only, disconnect the
counterbalance from the traction unit, remove the lock
pins from the brackets, separate the spring tension
assemblies from the brackets, and lay them down on the
deck. Loosely secure the lock pins to the brackets to
prevent from losing them (Fig. 21).

Danger
If the engine is started and the PTO shaft is
allowed to rotate, serious injury could result.
Do not start the engine and engage the PTO lever
when the PTO shaft is not connected to the gear
box on the cutting unit.
6. The deck carrier frame must be removed if the traction
unit will be used with any other accessory.
Servicing the Bushings in the
Castor Arms
The castor arms have bushings pressed into the top and
bottom portion of the tube which, after many hours of
operation, will wear. To check the bushings, move the
castor fork back and forth and from side to side. If the
castor shaft is loose inside the bushings, the bushings are
worn and must be replaced.
1. Raise the cutting unit so that the wheels are off of the
floor and block it so that it cannot accidentally fall.
2. Remove the lynch pin and thrust washers from the top
of the castor spindle.
3. Pull the castor spindle out of the mounting tube. Allow
the thrust washers to remain on the bottom of the
spindle.
4. Insert a pin punch into the top or bottom of the
mounting tube and drive the bushing out of the tube
(Fig. 23). Also drive the other bushing out of the tube.
Clean the inside of the mounting tube to remove any
dirt.
