Craftsman 917270822 lawn tractor Parts

On the Craftsman lawn tractor model 917270822, the owner’s manual lists the tractor as 19.5 HP. If you are asking about a generic 420cc Craftsman-branded engine, horsepower varies by engine design and tune, but this specific tractor is rated at 19.5 HP per the manual.

What to use as the “correct” horsepower

We recommend using the horsepower rating shown for your exact tractor model because decals and engine families can vary even when displacement (cc) looks similar.

• Check the cover and specifications section in the 917270822 owner's manual
• Look for the hood or dash decal that lists HP (often near the model and safety decals)
• Use the tractor model number (not just engine cc) when ordering parts
• If the engine was replaced, confirm the replacement engine’s label and spec tag

420cc vs HP: why the numbers do not match 1:1

Displacement (cc) measures engine size; horsepower depends on RPM, carburetion, compression, governor settings, and emissions tuning.

What you have	What it tells you	What it does not tell you
420cc (displacement)	Approximate engine size	Exact horsepower rating
HP rating (manual/decal)	Power rating for that configuration	Engine displacement
Model number 917270822	Correct parts and specs for the tractor	Specs for a different engine swap

Why it matters

Using the correct HP rating for Craftsman 917270822 helps you match maintenance parts and deck-drive components to the tractor’s intended setup, especially when troubleshooting performance or selecting mower deck parts.

The Craftsman lawn tractor model 917270822 uses a Briggs & Stratton engine; the engine model listed for this tractor is 42E707-2631-E1 (a 19.5 HP class engine). For the exact engine identification details and parts breakdown, use the 917270822 owner's manual.

How to confirm the engine model on your tractor

We recommend verifying the engine ID directly on the engine label because it matches you to the correct tune-up and repair parts.

• Park on a flat surface, set the parking brake, and remove the key
• Let the engine cool completely
• Locate the Briggs & Stratton ID label (often on the blower housing or valve cover area)
• Record Model, Type, and Code from the label
• Match the Model to 42E707 and the Type to 2631-E1

What “42E707-2631-E1” means

This is Briggs & Stratton’s engine identification format.

Label item	What it tells you	Example for this tractor
Model	Engine family/displacement series	42E707
Type	Specific configuration (carb, crank, charging, etc.)	2631-E1
Code	Build date code used for exact part revisions	Varies by unit

Why it matters

Using the correct engine model and type prevents ordering the wrong ignition parts, fuel system parts, or gaskets. It also ensures the right maintenance specs and diagrams when you service the mower deck, belts, and engine.

Craftsman model 917270822 identifies the tractor design and parts list, not a single guaranteed model year. To pin down the exact production year for your specific unit, match the tractor’s product/serial label information to the identification details in the 917270822 owner's manual.

How to find the year for your exact tractor

Use the tractor’s ID label and record these items; they are what we use to narrow the build period:

• Model number: 917270822
• Product number (often shown as “product” or “model/product”)
• Serial number
• Engine model and type (from the engine tag)
• Any date code printed on the label or tag

Where the ID label is usually located

On most Craftsman front-engine lawn tractors, the identification label is commonly found:

• Under the seat (seat pan area)
• On the frame rail near the rear wheels
• Near the hood support or engine compartment area

Clean the label gently so every digit is readable before you use it for parts lookup.

Why it matters

Craftsman tractors can keep the same model number across multiple production runs; small running changes affect belt length, steering components, and deck hardware. Confirming the exact product/serial information prevents ordering the wrong replacement part.

Common parts that vary by production run

These examples are configuration-sensitive on many 917-series tractors:

System	What can change	Example part
Ground drive	Belt length and routing	Lawn tractor ground drive belt 532140294
Steering	Shaft/sector gear design	Rally lawn tractor steering shaft kit 584371701
Mower deck	Mandrel style and pulley stack-up	Husqvarna lawn tractor mandrel assembly 532130794

On the Craftsman lawn tractor model 917270822, the choke control is on the dash/steering area as part of the engine speed controls. Many versions use a pull-out choke knob; you pull it out to start a cold engine, then push it back in as the engine warms up (see the 917270822 owner's manual).

How to identify the choke control

Look for one of these common setups near the steering wheel:

• A knob labeled CHOKE (often a pull knob)
• A choke symbol on the control panel (the manual’s symbol chart includes CHOKE)
• A combined throttle/choke control where the choke is at one end of the throttle range

How to use the choke correctly (cold start)

We recommend this basic routine for model 917270822:

• Set the parking brake and sit in the operator seat (seat switch must be made)
• Move the throttle to the recommended starting position
• Engage choke: pull the choke knob out (cold engine only)
• Start the engine
• As the engine smooths out, slowly push the choke in to disengage
• Run at full throttle for best mowing performance once warmed up

Quick reference: choke vs. throttle

Control	What it does	When to use it
Choke	Richens the fuel mixture for starting	Cold starts only
Throttle	Sets engine speed	After starting; mowing typically at full throttle

Why it matters

Using the choke only for cold starts helps prevent rough running, plug fouling, and power loss. The manual also notes that running with the throttle left in the choke position can contribute to poor performance.

For the Craftsman lawn tractor model 917270822, the engine is typically supplied by a major small-engine manufacturer (most commonly Briggs & Stratton, Kohler, or Kawasaki) depending on the exact production run and spec package; the sure way to identify yours is to match the engine brand and model on the engine label to the 917270822 owner's manual.

How to identify the engine maker on your 917270822

Use these quick checks on the tractor itself:

• Look for the engine shroud decal (top or side of the engine) showing the brand name.
• Find the engine model and type code stamped on the label (often near the valve cover or blower housing).
• Check the air cleaner cover; many engines print the brand there.
• Compare the horsepower and features listed on the tractor documentation (your manual shows a 19.5 HP, electric start tractor).
• Use the engine model code when ordering tune-up parts (spark plug, air filter, fuel filter).

What the owner's manual tells you (and what it does not)

Your Craftsman documentation for model 917270822 confirms the tractor configuration (19.5 HP, electric start, 42-inch mower deck) and provides maintenance specs such as oil type and spark plug type. It does not name a single engine manufacturer because this tractor platform was commonly built with different engine suppliers.

Key maintenance specs shown for this model

Item	Spec (from manual)
Engine oil type	SAE 30 (above 32°F), SAE 5W-30 (below 32°F)
Oil capacity	3.0 pints
Spark plug	Champion RJ19LM (or J19LM), gap 0.030 in
Tire pressure	Front 14 PSI, rear 10 PSI

Why it matters

The engine maker determines the correct engine-specific parts (carburetor parts, ignition coil, starter, air filter) and the right service procedures. The tractor model number 917270822 helps with chassis and deck parts, but the engine model number is what locks in the correct engine parts.
