Mounting The Cutting Units To The Traction Unit; Servicing The Blade Plane - Toro Groundsmaster 3505-D Operator's Manual

Mounting the Cutting Units
to the Traction Unit
1. Perform the pre-maintenance procedure; refer
to Preparing the Machine for Maintenance (page
37).
2. Move the cutting unit into position in front of the
traction unit.
3. Slide the cutting unit carrier frame onto the
lift-arm-pivot pin and secure it with the lynch pin
or retaining nut (Figure
4. Using the hydraulic-motor-mounting screws,
install the hydraulic motor to the cutting unit
(Figure 67).
Note:
Ensure that the O-ring is properly
positioned and not damaged.
5. Grease the spindle.

Servicing the Blade Plane

The rotary cutting unit comes from the factory preset
at 5 cm (2 inches) height-of-cut and blade rake of 7.9
mm (0.31 inch). The left and right heights of cut are
also preset to within ± 0.7 mm (0.03 inch) of the other.
The cutting unit is designed to withstand blade
impacts without deforming the chamber. If the blade
strikes a solid object, inspect the blade for damage
and the blade plane for accuracy.
Inspecting the Blade Plane
1. Remove the hydraulic motor from the cutting
unit and remove the cutting unit from the traction
unit.
Note:
Use a hoist (or a minimum of 2 people)
and place the cutting unit on a flat table.
2. Mark an end of the blade with a paint pen or
marker.
Note:
Use this end of the blade to check all
heights.
3. Position the cutting edge of the marked end
of the blade at the 12 o'clock position (straight
ahead in the direction of mowing) and measure
the height from the table to the cutting edge of
the blade (Figure
68).
69).
4. Rotate the marked end of the blade to the 3
o'clock and 9 o'clock positions and measure the
heights (Figure
5. Compare the 12 o'clock position measured
height to the height-of-cut setting.
Note:
It should be within 0.7 mm (0.03 inch).
The 3 o'clock and 9 o'clock heights should be
3.8 ± 2.2 mm (0.15 ± 0.09 inch) higher than the
12 o'clock setting and within 2.2 mm (0.09 inch)
of each other.
If any of these measurements are not within
specification, proceed to
(page 55).
Adjusting the Blade Plane
Start with the front adjustment (change 1 bracket at a
time).
1. Remove the height-of-cut bracket (front, left, or
right) from the cutting unit frame
