Servicing The Cutting Blades - Toro 74919TE Operator's Manual

13. If the deck is too low, tighten the single-point
adjustment bolt by rotating it clockwise. If the deck is
too high, loosen the single point adjustment bolt by
rotating it counterclockwise
Note: Loosen or tighten the single-point adjustment
bolt enough to move the height-of-cut plate mounting
bolts at least 1/3 the length of the available travel in
their slots. This will gain some up and down adjustment
on each of the 4 deck links.
14. Tighten the 2 bolts at the bottom of the height-of-cut
plate (Figure 98).
Note: In most conditions, the back blade tip should
be adjusted 6.4 mm (1/4 inch) higher than the front.

1. Single-point adjustment bolt
15. Torque the 2 bolts to 37 to 45 N∙m (27 to 33 ft-lb).
16. On both sides of the deck, measure from the level
surface to the back tip of the blade (position B) as
shown in Figure 94.
Note: The measurement should read 8.3 cm (3-1/4
inches)
17. Fine-tune the screw adjuster by turning it to get 8.3
mm (3-1/4 inches) height
Note: To increase the height, turn the adjustment nut
clockwise; to decrease, turn counterclockwise.
18. Measure until all 4 sides are the correct height.
19. Tighten all the nuts on the deck-lift-arm assemblies.
20. Lower the discharge chute.
