until the holes in the ball joint mount line up with the
holes in the castor arm. Immediately slide a 4 x 4 in.
block of wood between the top of the push arm and

the cutting unit mounting fasteners.
8. Carefully remove the wood block holding the push arm
down.
9. Pivot the blower rearward and secure the lift bracket to
the T-bar on the traction unit with the lift arm bracket
and pin.
Installing the Drive Shaft
Danger
The PTO shaft rotates with enough force to cause
serious injury.
Do not start the engine and engage the PTO lever
when the PTO shaft is not connected to the blower
gear box.
1. Remove the 5 capscrews, 6 washers, and nut securing
the belt guard to the blower frame (Fig. 6).
2. Slide the drive shaft onto the traction unit PTO shaft
(Fig. 6). Align the mounting holes in each shaft and
slide them together.
3. Secure them with a roll pin and 2 capscrews and nuts
(Fig. 6).

6. Secure them with a roll pin and 2 capscrews and nuts.
7. Install the belt shaft guard with the fasteners previously
removed (Fig. 6).
Note: To ensure proper blower operation, check/adjust the
blower belt tension after the first 20 hours of operation;
refer to Adjusting the Blower Belt, page 13.
Rear Ballast
The Groundsmaster 300 series 2WD traction unit complies
with the ANSI B71.4-1990 Standard when (5) 35 lb.
weights (Part No. 24-5790) are installed. Order two Weight
Kits, Part No. 24-5780 and one Weight Kit, Part No.
24-5790 from your Toro Distributor.
Greasing the Blower
Before the blower is operated, the PTO shaft must be
greased to ensure proper lubricating characteristics; refer to
Greasing the Blower in the Maintenance section;
page NO TAG. Failure to properly grease the unit will
result in premature failure of critical parts.
