Multiquip 42280 Block Motor Mount 2 DOF Pivot Assembly Kit

The Multiquip 42280 Block Motor Mount 2 DOF Pivot Assembly Kit is a genuine OEM component designed for PRX, LD6, LD6SL, LD60, STXDF, MD80, MD105, HTXG6DF, STX6H, and HTX6H series ride-on power trowels. This kit delivers the correct two-degree-of-freedom pivot geometry required to isolate and support the motor block on these machines. Sourced directly from Multiquip, part 42280 matches the original specification for a drop-in service replacement with no guesswork on fitment. If you run any of the listed PRX, STX, HTX, MD, or LD platform trowels, this is the correct mount kit for your machine.

Key Features

• Genuine OEM Pivot Geometry — Manufactured to Multiquip's original two-degree-of-freedom specification, ensuring the motor block pivots and articulates exactly as the machine was engineered to perform.
• Complete Assembly Kit — Supplied as a full kit with all mounting components included, allowing a straightforward block motor mount service without sourcing individual hardware separately.
• Broad Ride-On Trowel Compatibility — Confirmed fitment across PRX, LD6, LD6SL, LD60, STXDF, MD80, MD105, HTXG6DF, STX6H, and HTX6H series trowels — covering hybrid, hydrostatic, and heavy-duty platforms.
• Maintains Blade Deck Control — A correctly functioning motor mount keeps the motor block properly isolated and positioned, supporting accurate blade pitch response and consistent finishing performance across the deck.
• Direct Multiquip OEM Sourcing — Part number 42280 is supplied as a genuine Multiquip component, giving you confidence that the replacement matches the original part pulled from the machine.

The block motor mount assembly serves as the structural and isolation interface between the motor block and the trowel frame on ride-on power trowel machines. The two-degree-of-freedom pivot design allows controlled movement in two axes, accommodating operational loads and vibration while keeping the motor correctly oriented relative to the blade drive system. When this mount wears, cracks, or loses its pivot compliance, operators typically notice increased vibration transmitted to the frame, irregular blade pitch response, or visible movement in the motor block — all of which degrade finishing quality and accelerate wear on surrounding components.
