Multiquip EM20150 Left Palm Handle Kit with Switch

The Multiquip EM20150 Left Palm Handle Kit with Switch is a genuine OEM replacement designed for PRX, HTX, STX, LD, and HHX series ride-on power trowels. This kit restores the operator's left-hand control interface to factory condition, ensuring the machine responds accurately to every blade-pitch and throttle input. It is confirmed compatible with a wide range of Whiteman ride-on power trowel models including HTX44K4, HTX44K5, HTX44Y4, HTX44Y5, HTX6H, STX55J6, STX55Y6, STX6H, STXDF, LD6, LD60, and PRX series machines.

Key Features

• Genuine OEM Electrical Integrity — Correct switch resistance and circuit compatibility ensure the control input is read accurately by the trowel's operating system, preventing erratic blade response.
• Complete Kit for Direct Swap — Supplied as a full left palm handle assembly with switch integrated, so all critical components are replaced together in a single service operation.
• Broad Ride-On Trowel Coverage — Fits PRX hybrid, HTX44, HTX6H, HTXG6DF, STX55, STX6H, STXDF, LD6, LD60, HHXD5, HHXD5-ES, HHXDF4-DF5, and HHXG5 models.
• Restored Operator Control — A worn or failed palm handle switch causes loss of blade-pitch adjustment, leaving the operator unable to properly finish concrete surfaces. This kit brings full control authority back to the left hand.
• Operator Safety Compliance — The palm handle switch is part of the trowel's operator-presence control circuit. Replacing it with a genuine OEM unit maintains the integrity of the safety system as designed.

The left palm handle assembly is the primary operator interface on the left side of a ride-on power trowel's steering frame. The integrated switch signals the machine's control system to adjust blade pitch, allowing the operator to steer and control finishing pressure across the concrete surface. When the switch wears out or the handle assembly is damaged, blade response becomes inconsistent or non-functional, making precise finishing work impossible and potentially compromising operator safety through loss of directional control.
