Multiquip 20409-1 Left Trowel Blade Arm - OEM Replacement Part for Power Trowels

This left-side trowel blade arm controls blade pitch and movement during concrete finishing operations on ride-on power trowels. The arm attaches to the left spider assembly and holds the trowel blade at the correct angle for smooth, fluid rotation during finishing work.

Each trowel arm connects to the spider plate via a hex head bolt with integrated Zerk grease fitting for regular lubrication. The arm features a hexagonal shaft section at the top, round shaft body, and precision blade attachment bolt holes. Proper maintenance includes checking arm straightness regularly, as rough handling or striking exposed plumbing, forms, or rebar during operation can bend the arm and prevent smooth blade rotation. Bent arms should be checked using the trowel arm adjustment tool (P/N 9177) with adjustment bolts set to .010" distance specification.

The silver-finished arm includes lever mounting slots and roll pin configuration specific to left-side counterclockwise blade rotation. Regular inspection and adjustment ensures even pitch and flat finishing performance.
