Husqvarna Z254-967638501-00 rear-engine riding lawn mower Parts

The Husqvarna Z254-967638501-00 is a Z254-series zero-turn mower that commonly comes equipped with a Kawasaki FR-series V-twin engine (most often the FR691V, 23 HP class). To confirm the exact engine on your mower, match the engine model and spec numbers printed on the engine ID label.

Look for the engine identification label (usually on the blower housing, valve cover area, or near the starter). Record:

• Engine manufacturer (often Kawasaki)
• Engine model (example: FR691V)
• Spec or type code (narrows down the exact build)
• Serial number (helps with parts lookups)
• Any emissions family label (useful for service matching)

Use this table to make sure you are reading the right information:

The engine model and spec code determine the correct maintenance parts and service procedures (oil filter, air filter, spark plugs, starter components). If you’re troubleshooting a no-crank or intermittent starting issue, the mower’s starting circuit parts are also key, such as the lawn tractor starter solenoid 582042802.

If you need to test the solenoid, ignition switch circuit, or PTO safety interlocks, use a meter and follow safe testing practices. Our guide how to use a multimeter to test electrical parts video walks through the basics.

The Husqvarna Z254-967638501-00 is a residential zero-turn mower, not a true commercial mower. It is built for homeowner lawn care and light property maintenance; commercial mowers are typically heavier-duty with higher-hour components and serviceable driveline systems.

• Duty cycle: residential mowers are designed for weekly mowing; commercial units are built for daily, all-day use
• Deck and frame: commercial decks and frames are thicker and more impact-resistant
• Hydro drives: commercial units usually have heavier, serviceable hydro pumps and wheel motors
• Spindles and pulleys: commercial spindles often have larger bearings and longer service intervals
• Controls and ergonomics: commercial models prioritize operator comfort for long shifts

Some residential mowers are described as having “commercial power” or “commercial-grade” features (for example, higher horsepower or a fabricated deck). That wording points to performance features, not the mower’s overall commercial duty rating.

If you are maintaining a Z254-967638501-00 for heavier use, these wear and control parts are the ones we see customers replace most often:

• Husqvarna lawn tractor deck idler pulley 532196106 (belt tension and deck drive)
• Husqvarna lawn mower idler pulley, left-hand stationary 532196104 (idler routing and belt tracking)
• Husqvarna lawn tractor blade idler spring 532196105 (maintains proper belt tension)
• Husqvarna lawn tractor electric clutch 587241601 (PTO engagement for the deck)

Using a residential mower like the Z254-967638501-00 in a commercial schedule can shorten belt, pulley, spindle, and PTO clutch life. Matching the mower’s duty rating to your mowing hours helps prevent downtime and repeat repairs.

A Husqvarna Z254-967638501-00 rear-engine riding lawn mower is typically worth about $1,500 to $2,800 on the used market, with the exact value driven by condition, hours, deck condition, and local demand. For repair-related value, pricing out key replacements from our parts list helps you estimate total cost to get it mowing again.

• Engine hours and starting reliability (hard-starting or no-crank lowers value)
• Deck condition (rust-through, cracks, or a bent housing lowers value)
• PTO engagement and cut quality (slipping, squealing, uneven cut)
• Hydro drive response (slow, surging, or weak hill performance)
• Tires, steering, and seat condition (cosmetic and safety items still matter)

If you are deciding whether to fix or sell, these parts often swing the math:

• No-crank or intermittent crank: lawn tractor starter solenoid 582042802
• Blades not engaging or PTO issues: switch.pto.8 582107601 and Husqvarna lawn tractor electric clutch 587241601
• Belt routing/tension problems: Husqvarna lawn tractor deck idler pulley 532196106 and Husqvarna lawn mower idler pulley, left-hand stationary 532196104
• Deck damage: Husqvarna craftsman lawn tractor 54-in deck housing 583909301

A mower’s resale value is closely tied to whether it can start reliably and cut consistently. Even a single high-impact issue (like a failing electric clutch or a damaged deck housing) can cost enough in parts and labor to shift the best choice from “repair” to “sell as-is.”

Using the full model number helps ensure you get the correct parts for your exact build.
