Craftsman 917299570 roto-spader Parts

For Craftsman parts for model 917299570 (roto-spader lawn tractor attachment), we recommend starting with the model-specific parts listing and diagrams on Sears PartsDirect so you can match the exact component by model number and illustration callout. If you are sourcing more broadly, use your model number and the part description to confirm fit.

Best way to get the right part for model 917299570

Using the model number is the fastest way to avoid ordering the wrong item, especially on older Craftsman attachments where similar-looking hardware and drive components can vary.

• Confirm the model number on the ID tag: 917299570
• Use the exploded-view diagrams to identify the exact assembly (drive, gearbox, tine shaft, guards)
• Match the part description to your failed component (for example: chain, sprocket, bearing, shear bolt)
• Compare mounting style and measurements (bore size, keyway, tooth count) before ordering
• Order using the model number search on Sears PartsDirect

What to check before you buy

Small differences can cause big fit issues on roto-spader style attachments.

What to verify	Why it matters
Attachment model number	Ensures the parts list matches your exact unit
Assembly location	Prevents buying a similar part from the wrong section
Dimensions and tooth counts	Critical for sprockets, chains, and drive parts
Hardware grade and length	Prevents breakage and misalignment

Why it matters

Craftsman lawn tractor attachments often share design families, but parts can change across production runs. Starting with the correct model-based lookup reduces returns and gets your roto-spader back in service faster.

To tell what year your Craftsman riding mower is, we use the model and serial number on the product ID label and decode the date information embedded in the serial number. The label is usually under the seat, on the frame, or near the engine area.

Where to find the model and serial number

Check these common locations on Craftsman riding mowers and lawn tractors:

• Under the seat pan or on the seat support
• On the rear fender deck (left or right side)
• On the frame rail near the footrest
• Under the hood near the dash tower
• Near the engine mounting area (sometimes on a separate engine label)

How to decode the year from the serial number

Many Craftsman riding mowers use a 6-digit date code within the serial number in this format:

• MMDDYY (month, day, year)
• Example: 031398 = March 13, 1998

If your label shows a longer serial number, look for a 6-digit block that matches a valid month and day.

Quick decode table

Serial digits	Meaning	Example
First 2	Month (MM)	03 = March
Next 2	Day (DD)	13
Last 2	Year (YY)	98 = 1998

If the serial format does not match MMDDYY

Craftsman has used more than one labeling format over the years. If you do not see a clean MMDDYY pattern:

• Look for a manufacture date printed separately on the label
• Check for a letter-coded year on newer labels (some newer units use letters instead of a 2-digit year)
• Use the model number to narrow the era, then confirm with the serial/date code
• If your mower has multiple labels (tractor and engine), use the tractor frame label for the mower’s build date

Why it matters

Knowing the build year helps us match the correct parts and diagrams, especially for wear items like belts, blades, pulleys, idlers, and attachment hardware. It also reduces the chance of ordering a look-alike part that does not fit.

For help matching parts once you have the model number, search by model on Sears PartsDirect.

Craftsman riding mowers most often have trouble starting, staying running, engaging the blades, or moving under load. If you are troubleshooting while using the Craftsman 917299570 roto-spader attachment, focus first on the tractor basics (fuel, spark, battery) and then on attachment-related drag or belt issues.

Common mower symptoms (and what they usually point to)

• No crank or clicking: weak battery, corroded terminals, starter solenoid, safety switches (seat, brake)
• Cranks but will not start: stale fuel, clogged fuel filter, dirty carburetor, fouled spark plug, ignition coil
• Starts then dies or surges: restricted fuel cap vent, dirty carburetor jets, plugged air filter, water in fuel
• Blades will not engage (mower deck): worn deck belt, idler/tensioner issue, PTO switch or electric clutch
• Won’t move or slips on hills: worn drive belt, idler/tensioner problem, transmission linkage out of adjustment

When the issue shows up only with the 917299570 attachment

A roto-spader adds load. If the tractor runs fine alone but struggles with the attachment, check these first:

• Attachment drive belt condition and tension (if equipped)
• Binding in the attachment drivetrain (chain, gearbox, bearings)
• Debris jammed in the spader mechanism
• Tractor engine speed set to full governed RPM before engaging

Quick checks we recommend first

• Use fresh fuel; replace old fuel in the tank and can
• Clean and tighten battery terminals
• Inspect belts for cracks, glazing, or slack
• Check air filter condition and cooling-air blockage

Symptom-to-check table

Symptom	Check first	Typical fix
Clicks, no crank	Battery and terminals	Charge/replace battery; clean terminals
Cranks, no start	Spark plug and fuel flow	New plug; fresh fuel; clean carburetor
Dies under load	Air filter, fuel delivery	Replace filter; clean carburetor
Loses drive	Drive belt and tensioner	Replace belt; repair tensioner

Why it matters

A mower that is already running lean, weak on spark, or slipping a belt will fail faster under attachment load; fixing the base tractor issue prevents repeat stalling and premature belt or clutch wear.
