Starting And Stopping The Engine - Toro Groundsmaster 4100-D 30411 Operator's Manual

6. Cut grass in a test area to determine if all cutting
units are cutting at the same height.
7. If cutting unit adjustments are still needed, find a flat
surface using a 6 foot (2 m) or longer straight edge.
8. To ease measuring blade plane, raise the height of
cut to the highest position; refer to Adjusting the
Height of Cut.
9. Lower cutting units onto the flat surface. Remove
the covers from the top of the cutting units.
10. Loosen the flange nut, securing the idler pulley, to
release the belt tension on each cutting unit.
Center Cutting Unit Setup
Rotate blade on each spindle until the ends face forward
and backward. Measure from the floor to the front
tip of the cutting edge. Adjust 1/8 inch shims on
front castor fork(s) to match height of cut to decal
(Figure 26); refer to Adjusting the Cutting Unit Pitch
procedure in Mower Maintenance, page 52.

Wing Cutting Unit Setup
Rotate blade of each spindle until the ends face forward
and backward. Measure from the floor to the front
tip of the cutting edge. Adjust 1/8 inch shims on
front castor arm(s) to match height of cut to decal
(Figure 27). For the outside blade spindle only, refer to
4. Shims
5. Axle mounting holes

Matching Height Of Cut Between Cutting Units
1. Position blade side to side on outside spindle of
both wing cutting units. Measure from the floor
to the tip of the cutting edge on both units and
compare. These numbers should be within 1/8 inch
(3 mm) of each other.
2. Add or remove 1/8 inch shims as needed on wing
castor wheels. Recheck measurement between
outside edges of both wing cutting units and adjust
as necessary.
Starting and Stopping the
Engine
Important: The fuel system will automatically
bleed itself when any of the following situations
occur:
• Initial start up of a new machine.
• The engine has ceased running due to lack of fuel.
• Maintenance has been performed upon the fuel
system components.
Refer to the Bleeding Air from the Injectors procedure
in Fuel System Maintenance , page 40.
1. Ensure that the parking brake is set. Remove your
foot from the traction pedal and ensure that it is in
neutral.
