Craftsman 107277860 zero-turn rear-engine riding lawn mower Parts

Craftsman uses engines from multiple manufacturers across its mower lineup; the engine brand depends on the specific mower model and engine family. For your Craftsman model 107277860 rear-engine riding mower, confirm the exact engine make and model using the identification information and specifications in the owner's manual.

Use these quick checks on the mower itself (they are faster than guessing by series name):

• Look for an engine label on the blower housing (top of the engine) or valve cover
• Check the emissions label; it often lists the engine manufacturer and displacement
• Record the engine model, type, and code numbers (common on Briggs & Stratton engines)
• Match those numbers to the engine parts breakdown when ordering service parts
• If the label is missing, use the mower model number 107277860 to cross-reference the correct engine family in the documentation

Craftsman has historically sourced engines from several major small-engine makers. Which one you have is model-specific.

The engine brand determines the correct tune-up parts and service specs (spark plug type, air filter, oil capacity, governor settings). It also prevents ordering the wrong gasket, belt, or hardware for repairs tied to engine mounting and exhaust routing.

If you’re chasing an exhaust leak (popping sound, soot near the muffler, loss of power), replacing the gasket is a common first step. For this model’s parts list, we stock the exhaust gasket 690970.

The model number for this Craftsman rear-engine riding mower is 107277860. In the operator documentation, it’s listed as a ZTS 7500 series model (42-inch mower deck variant); you can confirm the exact labeling and deck size details in the owner's manual.

We recommend matching the printed model number on the mower’s ID label to 107277860.

• Check under the seat area near the seat support and frame
• Look on the rear frame rails near the engine compartment
• Check around the footrest or fender pan area
• Wipe dirt and grass off the label so all digits are readable
• Record the full model number exactly as shown (including any punctuation)

The ZTS 7500 name is a series/line identifier, while 107277860 is the specific model number used to match parts and documentation.

Using the exact model number prevents ordering the wrong belt, brake, or hardware. For example, drive and control components can vary by deck size and production run, even within the same mower series.

If you’re confirming fitment while troubleshooting, these are common part categories shown for model 107277860:

• Ground drive belt and pulleys
• Parking brake and linkage
• Transmission and hydro components
• Decals and safety labels
• Fasteners (nuts, screws, bolts)

For your Craftsman riding mower, we look up the model number by finding the model tag on the mower and matching the full number exactly (for this page, the model is 107277860). On many Craftsman riders, the tag is under the seat or on the frame near the engine or rear fender area; confirm the exact location in the owner's manual.

Check these common spots first (wipe dirt and grass off the tag so every digit is readable):

• Under the seat pan or on the seat support area
• On the frame rail near the rear wheels
• Near the engine compartment or muffler heat shield area
• Under the footrest area or on the chassis near the pedals
• On a fender or rear body panel (inside edge)

Use the full model number exactly as shown on the tag. For Craftsman equipment, we also recommend recording any additional identifiers printed nearby.

Craftsman riding mowers often share similar frames across multiple models, but key parts can differ by deck size, transmission setup, and control linkage. Using the exact model number helps you land on the correct diagrams and prevents ordering the wrong belt, brake, or hardware.

Use the mower’s physical configuration to narrow it down:

• Measure the cutting deck width (blade tip to blade tip across the deck)
• Note whether it is rear-engine and the control style
• Compare the parts you need to common wear items listed for this model (for example, a ground drive belt like the lawn tractor ground drive belt 1734048SM)

Common problems on Craftsman riding mowers like model 107277860 usually fall into a few buckets: no-start or weak-start conditions, engine stalling under load, blades not engaging, and drive or traction issues. Many of these trace back to routine maintenance items, worn belts, or safety interlock and brake-related problems (see the 107277860 owner's manual).

• Won’t crank or cranks slowly: weak battery, dirty/loose battery cables, failed starter solenoid, safety switch not made (seat, brake, PTO).
• Cranks but won’t start: stale fuel, clogged fuel filter, fouled spark plug, carburetor varnish.
• Starts then dies or stalls while mowing: restricted fuel flow, dirty cooling/air intake areas, plugged bagger chute or heavy/wet grass load.
• Blades won’t engage or cut is uneven: PTO not engaged, worn or slipping belt, debris buildup under the deck.
• Poor drive, slipping, or no movement: worn ground drive belt, linkage out of adjustment, transmission or hydro drive issues.

1. Confirm safety interlocks: parking brake set, PTO disengaged, operator seated.
2. Inspect belts and pulleys for glazing, cracking, or slack.
3. Check fuel quality and look for fuel restriction symptoms (surging, dying on hills).
4. Clear deck and chute buildup; the manual notes wet grass and debris can plug the collector chute and cause stalling.
5. Use safe shutdown steps before clearing jams: disengage PTO, stop engine, remove key, set parking brake, wait for all moving parts to stop.

Catching belt wear, brake issues, and clogging early prevents bigger failures (overheated belts, damaged pulleys, poor control on slopes). The manual also emphasizes safe mowing practices, including avoiding steep slopes and shutting down correctly before clearing a plugged chute.
