Craftsman 917256580 rocker arm & pivot lawn tractor Parts

Craftsman model 917256580 was made across a production run (not a single model year). The exact year for your tractor is determined by the serial number on the ID tag, not the 917 model number itself.

Look for the model and serial tag in one of these common spots:

• Under the seat pan (lift the seat)
• On the rear fender pan near the seat
• On the frame rail near the engine

Once you find the serial number, use this quick method:

• The first 6 digits typically represent the month, day, and year (MMDDYY)
• Example: 041503 reads as April 15, 2003

The build year affects which parts fit your Craftsman riding mower, especially for deck and drive components like the blade drive belt, mandrel parts, and electrical starting parts.

When you confirm the year, we use it to help you choose the correct replacement parts, such as:

• Lawn tractor drive belt 532144200 (deck/blade drive belt)
• Solenoid 532146154 (starter solenoid)
• Husqvarna lawn tractor mandrel assembly 532130794 (spindle/mandrel assembly)
• Molded ignition key 532140403 (ignition key style)

The model number for this Craftsman riding mower is 917256580. Use 917256580 when looking up parts diagrams and ordering replacement items like belts, blades, or electrical parts for your front-engine lawn tractor.

Most Craftsman riding mowers have a model and serial tag in one of these spots:

• Under the seat on the seat pan or frame
• On the rear fender deck near the seat
• On the frame rail near the engine
• Near the steering column or dash support

Craftsman model numbers identify the exact configuration of your mower (deck setup, drive system, and hardware). That is what ensures you get the right replacement part the first time.

Here are a few common parts listed for model 917256580:

• Match the mower model number exactly: 917256580
• Compare the part name and part ID to your old part when possible
• Replace worn deck-drive items together (blade, belt, and mandrel components) if you have vibration or poor cutting

Using the correct model number prevents ordering parts that look similar but mount differently, have the wrong length, or do not match your deck and engine setup.

Craftsman is a brand name, and the company that actually manufactured a Craftsman lawn tractor can vary by model and production era. For Craftsman model 917256580, the tractor was built for Craftsman by a major outdoor power equipment manufacturer; you can confirm fitment by matching parts to this model’s parts list.

Craftsman has historically sourced riding mowers and lawn tractors from different manufacturers. The most reliable way to identify what fits your tractor is to use the model number and the parts diagrams for 917256580.

Common indicators you can use:

• The model number prefix (for example, many 917.xxxxx models are associated with a specific manufacturer family)
• The engine brand (often Kohler, Briggs and Stratton, etc.)
• The deck and spindle (mandrel) design used on the mower deck
• The electrical system layout (key switch, solenoid, wiring harness)

When you see parts like a mandrel assembly, blade drive belt, and starter solenoid listed for your exact model, that confirms you are looking at the correct manufacturer configuration for your tractor.

Examples of model-matched parts on this page:

• Solenoid 532146154
• Lawn tractor drive belt 532144200
• Husqvarna lawn tractor mandrel assembly 532130794

Knowing who manufactured the tractor is less important than matching the correct Craftsman model number (917256580) to the right OEM-spec parts. That prevents belt misrouting, incorrect spindle fit, and electrical no-start issues caused by mismatched solenoids or keys.

The Craftsman riding mower model 917256580 uses a single-cylinder gasoline engine; the exact engine brand and horsepower can vary by build and engine family used on this tractor. The most reliable match is to identify the engine model from the engine shroud tag, then order tune-up and starting parts by that ID.

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

• Engine manufacturer name (commonly Briggs & Stratton or Kohler on many Craftsman tractors)
• Engine model number
• Type/spec code
• Code/date (helps match carburetor and ignition parts)

These visual cues narrow it down fast:

• Oil filter present: many single-cylinder engines use a spin-on filter; if yours does, match it to the oil filter 12-050-01-s1
• Starter solenoid style: compare your solenoid mounting and terminal layout to the solenoid 532146154
• Deck size and layout: many 917-series tractors commonly run a 42-inch deck; deck parts like the husqvarna lawn tractor mandrel assembly 532130794 and lawn tractor drive belt 532144200 are often tied to that deck configuration

The engine model (not just the tractor model) determines the correct ignition, carburetor, starter, and maintenance parts. Using the engine tag info prevents ordering the wrong oil filter, solenoid, or carburetor parts.

Yes, replacing the engine on your Craftsman 917256580 front-engine lawn tractor is worth it when the deck, transmission, and steering are solid and the total engine-swap cost stays well below the value of a comparable replacement tractor; it is a poor investment when the chassis and driveline are worn or multiple major systems need work.

• Deck condition: no severe rust-through, cracks, or bent mounting points
• Transmission and drive: tractor moves strongly forward and reverse, no slipping or loud grinding
• Steering and front end: tight steering, no excessive wheel wobble (bearings, bushings)
• Electrical starting: key switch and wiring are serviceable (a no-crank issue can be inexpensive)
• Parts availability: common wear parts are still easy to get for your model

A practical rule is to replace the engine when the all-in cost (engine, hardware, belts, fluids, and your time or labor) is well under half the cost of a similar replacement tractor in comparable condition.

Many “dead engine” complaints are actually starting or deck-drive issues:

• No crank: battery connections, safety switches, starter circuit, or a bad solenoid
• Cranks but will not start: fuel delivery, carburetor condition, ignition, stale fuel
• Runs but will not mow well: blade condition, belt slip, mandrel/spindle wear

If you have a no-crank symptom, start by inspecting or testing the solenoid 532146154 and the key circuit.

An engine swap is only a win if it restores a tractor that is already mechanically sound. If the deck, belt drive, and mandrels are worn out, you can spend engine money and still end up with poor cut quality and frequent downtime.

• Lawn tractor drive belt 532144200 (if glazed, stretched, or oil-soaked)
• Oil filter 12-050-01-s1 (basic maintenance after installation)
• Molded ignition key 532140403 (if the original is worn or intermittent)
