Key Features
- Genuine OEM Filtration Media — Manufactured to Multiquip's exact filtration standards, ensuring the correct micron rating and media density for the engines used across the HTX44 and MQ62TK platforms.
- Drop-In Replacement — Engineered to seat directly into the factory airbox housing without modification, maintaining the original sealing surface and air intake path.
- Broad HTX44 Series Coverage — Compatible with HTX44K4, HTX44K5, HTX44Y4, and HTX44Y5 ride-on trowels, as well as the MQ62TK trash pump — one part number spans multiple machines.
- Protects Engine Internals — A correctly functioning air filter keeps contaminants out of the combustion chamber; a clogged or degraded filter leads to rich running, power loss, and accelerated cylinder wear.
- Supports Proper Fuel-Air Mixture — Unrestricted, clean airflow is critical on trowel and pump engines working under sustained load — this filter maintains the airflow balance the engine relies on.
An air filter's job is to strip dust, dirt, and debris from incoming air before it reaches the carburetor and engine cylinder. On equipment like ride-on power trowels and trash pumps that operate in dusty, debris-heavy environments, a clean air filter is one of the most important service items on the machine. When the filter becomes clogged or damaged, the engine is starved of clean air, causing rough running, increased fuel consumption, and in severe cases, abrasive material entering the engine and causing premature wear. Replacing the 21751-001 on schedule is a simple step that directly protects the life of the engine.
