The Multiquip 42602 is a genuine OEM Engine Hatz 4H50TIC designed for HTX6H and STX6H Whiteman ride-on power trowels. As a direct OEM component, this engine was sourced and supplied to the exact specifications Multiquip required for these hydrostatic trowel platforms. Please note that this part carries an NLA (No Longer Available) designation, meaning it has been discontinued by the manufacturer — confirm current stock availability with DHS Equipment before placing your order. If you are sourcing 42602 for a HTX6H or STX6H trowel, act promptly, as remaining inventory of discontinued OEM engine assemblies is typically limited.
Key Features
- Genuine OEM Engine Assembly — Sourced directly to Multiquip specification, ensuring the correct displacement, mounting configuration, and output rating for these trowel models.
- Hatz 4H50TIC Power Unit — The Hatz 4H50TIC is a purpose-built diesel engine known for compact dimensions and reliable output in concrete finishing equipment applications.
- Direct Application for HTX6H and STX6H — Engineered specifically for Whiteman hydrostatic ride-on trowels, with correct interface points for the hydraulic drive system and frame mounting.
- NLA Status — Verify Availability First — This part has been discontinued; current stock reflects remaining OEM inventory only. Confirm with DHS Equipment before ordering.
- Critical Drive Source for Hydraulic Trowel Operation — The engine powers the hydraulic system that controls both blade pitch and machine propulsion; a failed or worn engine directly stops finishing operations on the slab.
The engine on a hydrostatic ride-on trowel is the primary power source for the machine's entire hydraulic circuit. On the HTX6H and STX6H, that hydraulic circuit drives both the rotor blade pitch control and the propulsion system, meaning the engine is not just a mobility component — it dictates the trowel's ability to finish concrete at all. When the engine loses output, overheats, or fails entirely, the operator loses control of blade speed and machine movement, bringing finishing work to a halt. Replacing a failed engine with the correct OEM unit, such as the Multiquip 42602, ensures all hydraulic interfaces, throttle linkages, and mounting points align without modification.
