Blade Pitch

Matching Blade Pitch for Both Sets of Blades

Sometimes it may be necessary to match blade pitch between the two sets of blades. There are some signs that this may be necessary. For example, the differences in pitch could cause a noticeable difference in finish quality between the two sets of blades, or, the difference in blade pitch could make the machine difficult to control. This is due to the surface area in contact with the concrete (the blade set with the greater contact area tends to stick to the concrete more).

Single Pitch

On a Single Pitch trowel each spider assembly can be pitched individually, forcing the operator to constantly make adjustments on each pitch tower.

Twin PitchTM

Trowels equipped with Twin PitchTM Controls may need to have blade pitch between the two sets of blades "syncronized". If the blades need to be syncronized this is easily accomplished by performing the following. Refer to Figure 33.

1.Lift the pitch adjustment handle on either side. Once lifted, that side is now disconnected from the Twin Pitch system.

2.Adjust to match the opposite side.

3.When adjusted, lower the handle to Twin Pitch operating position.

Blade Pitch Adjustment Procedure

Maintenance adjustment of blade pitch is made by adjusting a bolt (Figure 34) on the arm of the trowel blade finger. This bolt is the contact point of the trowel arm to the lower wear plate on the thrust collar.The goal of adjustment is to promote consistent blade pitch and finishing quality.

Look for the following indications if blades are wearing unevenly. If so, adjustment may be necessary.

„„Is one blade is completely worn out while the others look new?

„„Does the machine have a perceptible rolling or bouncing motion when in use?
