Husqvarna YTA18542: 42-Inch Riding Lawn Tractor with Briggs and Stratton Engine Service
The Husqvarna YTA18542 uses a Briggs and Stratton 18.5 gross horsepower single-cylinder engine and a 42-inch cutting deck with two blades. Two-blade 42-inch decks use separate deck engagement belts and drive belts. The deck engagement belt connects the engine to the blade spindles and is separate from the ground drive belt that propels the tractor. Annual carburetor float bowl draining before winter storage prevents the most common YTA18542 hard-start complaint at the start of the mowing season. The lawn mower repair help section covers YTA18542 deck belt routing, blade replacement, and carburetor service.
Most Replaced Parts on the Husqvarna YTA18542
Cutting Blades for the Husqvarna YTA18542
The 42-inch deck uses two cutting blades. Replace both blades simultaneously when either is bent or worn to maintain balanced cutting across the full deck width.
Deck Engagement Belt for the YTA18542
The deck engagement belt connects the engine to the blade spindles. A belt that is cracked, glazed, or worn slips under load and reduces or eliminates blade engagement.
Carburetor for the Husqvarna YTA18542
Ethanol varnish deposits during winter storage cause most Briggs and Stratton engine hard-start complaints. Draining the float bowl before off-season storage prevents this.
Spark Plug for the YTA18542
Annual spark plug replacement maintains reliable starting on the Briggs and Stratton engine. A plug with black carbon deposits indicates a rich mixture from a clogged air filter or gummed carburetor.
