Connecting the PTO Shaft and
Installing the Lift Chains
Important The PTO shaft yokes must be exactly in line
with each other when the outer PTO sleeve is installed on
the splined shaft. Remove the sleeve and change the yoke
position if the alignment is not correct. Misalignment of the
two yokes will shorten the life of the PTO shaft assembly
and cause unnecessary vibration when the cutting unit is
operated.
1. Line up the holes in the yoke and input shaft of the gear
box. Slide the yoke onto the shaft (Fig. 14) and secure
the parts together with a roll pin (3/16 x 1-1/2 in.).
Tighten the 2 capscrews and locknuts securing the yoke
to the input shaft.

2. Mount the PTO shield over the input shaft and onto the
gear box mounting plate with two self-tapping screws
(Fig. 15).
3. Attach the lift chains to the lift arm and cutting unit
(Fig. 15) with 6 shackles, shackle pins (3/8 x 1-1/2 in.),
and cotter pins (1/8 x 3/4 in.). Adjust the chain length
so that both become tight at the same time when lifting
the lift arm.
4. Connect the ends of the tension spring between the
fourth link of the rear chain and the eye of the cotter pin
that holds the cylinder pin in place (Fig. 15). Adjust the
length of the chain so that the rear caster wheels are off
of the ground in the transport position.

Greasing the Cutting Unit

Before the cutting unit is operated, it must be greased to
ensure proper lubricating characteristics; refer to Greasing
the Bearings, Bushings, and Gear Box, page 16. Failure to
grease the machine will result in premature failure of
critical parts.

Installing Rear Weight

Two Wheel Drive Groundsmaster 300 Series traction units
comply with the ANSI B71.4-1999 Standard when
equipped with rear weight. Refer to the chart in the traction
unit Operator's Manual to determine the combinations of
weight required. Order the parts from your local
Authorized Toro Distributor.
Four Wheel Drive Groundsmaster 300 Series traction units
do not need additional rear weight to comply with the
ANSI B71.4-1999 Standard.
