Craftsman 107277680 zero-turn rear-engine riding lawn mower Parts

For the Craftsman 107277680 zero-turn rear-engine riding mower, the operator’s manual specifies a Briggs & Stratton engine (19 HP) paired with a 42-inch mower deck. For other Craftsman riding mowers, engine brands can vary by model and series, so always match parts and service info to your exact model number.

What this means for parts and maintenance

When you know the engine brand, you can choose the correct tune-up and repair parts (filters, ignition parts, gaskets) and follow the right service intervals.

• Use the engine make and model from the ID tag when ordering engine-related parts.
• Check the underside of the seat for the mower’s identification tag.
• Record the engine code/serial number for accurate parts matching.
• Follow the maintenance schedule in the owner's manual to reduce hard-starting and power-loss issues.

Where to find the engine information on model 107277680

The manual notes the identification tag is under the seat; tilting the seat forward gives access. That tag is where you’ll typically find:

• Model description name/number
• Unit serial number
• Engine make (brand)
• Engine model
• Engine type/spec
• Engine code/serial number

Quick reference: this model vs. other Craftsman models

Best way to confirm	Operator’s manual and ID tag	ID tag and model-specific manual
Parts matching	Use model number + engine model/spec	Use model number + engine model/spec

Why it matters

Engine brand and engine model/spec determine the correct replacement parts and adjustments. Using the wrong engine parts can cause poor performance, leaks, or premature wear.

Common problems on the Craftsman 107277680 rear-engine riding mower include no-start conditions (controls not in PARK, PTO ON, stale fuel, weak battery), drive issues (belt slip or broken belt), parking brake not holding, and uneven cutting from dull blades or deck setup. See the owner's manual troubleshooting tables for model-specific checks.

Most common symptoms and what usually causes them

• Engine will not turn over or start: controls not in PARK, PTO switch ON, choke/key position, out of fuel, flooded engine, old or water-contaminated fuel, dirty battery terminals, discharged battery, faulty spark plug, loose/broken wiring
• Engine runs but mower will not drive: transmission release levers left in PUSH position, drive belt slipping or broken
• Parking brake will not hold: brake not fully released, brake incorrectly adjusted
• Uneven or rough cut: tire pressure mismatch, deck not level, ground speed too fast, engine speed too low, dull blades, oily or worn mower drive belt
• Vibration or stalling with blades engaged: loose blade hardware, bent/out-of-balance blades, dirty deck underside, chute plugging

Quick checks we recommend first (fast, no parts needed)

1. Set ground speed controls to PARK and confirm the PTO is OFF before starting.
2. Verify fresh fuel; drain and replace old fuel if it smells sour or looks dark.
3. Check the battery terminals for corrosion and tightness.
4. Confirm transmission release levers are in the DRIVE position (not PUSH).
5. Set throttle to FULL when mowing and slow ground speed if the engine bogs.

Troubleshooting guide by problem area

Problem area	What you notice	Most likely fix path
Starting/safety interlocks	No crank or no start	PARK and PTO OFF checks; fuel and battery basics; spark plug and wiring inspection
Drive system	Engine runs, no movement	Verify release levers; inspect drive belt for wear, glazing, or breakage
Parking brake	Mower creeps or won’t hold on flat ground	Confirm full release; adjust brake per manual
Cutting quality	Uneven cut, rough look, stalls with blades on	Level deck, match tire pressure, sharpen/replace blades, clean deck underside

Why it matters

Catching belt slip, stale fuel, and brake adjustment issues early prevents bigger problems like overheating belts, hard starting, poor traction, and unsafe handling on slopes.

A rear-engine riding mower like the Craftsman 107277680 puts the engine weight over the drive wheels, which improves traction on flat lawns and makes the mower compact and easy to maneuver around trees, beds, and tight gates. It is a practical choice for smaller to mid-size yards.

Key advantages you will notice

• Better traction: rear weight bias helps the drive wheels grip when starting and turning.
• Compact footprint: typically easier to store and fit through narrower openings than larger tractors.
• Good maneuverability: shorter overall length helps you trim around obstacles with fewer back-and-forth moves.
• Simpler deck access: many rear-engine riders are designed for straightforward deck height changes and belt routing.
• Comfortable visibility: the hood area is lower than many front-engine tractors, so it is easier to see ahead.

What to keep in mind (trade-offs)

Rear-engine riders are optimized for maneuvering and routine mowing, not heavy towing or steep terrain.

• They are best on level to gently rolling lawns.
• They usually have less ground clearance than larger lawn tractors.
• They are not the first pick for frequent heavy attachments.

Quick comparison

Feature	Rear-engine riding mower (like 107277680)	Lawn tractor (front-engine)
Maneuverability	High	Medium
Storage space needed	Lower	Higher
Best yard size	Small to mid-size	Mid to large
Heavy towing/ground work	Limited	Better

Why it matters

Choosing the right layout affects cut quality and safety. For example, the owner's manual emphasizes shutting the engine off, removing the key, and disconnecting the spark plug wire before clearing blockages or servicing the mower deck. Following those steps is easier when the mower is sized and configured for your yard.

Craftsman model 107277680 is a ZTS 7500 zero-turn rear-engine rider (19 HP Briggs & Stratton with a 42-inch mower deck), but the model number by itself does not identify a single model year. To get the exact year for your mower, match the manufacture date on the ID tag to the date format shown in the 107277680 owner's manual.

How to find the year on the mower

Look for the product identification label, then use the date information on that label to determine the year.

• Check under the seat and around the seat deck/frame rails for the model and serial label.
• Clean the label gently so the serial/date code is readable.
• Write down the full serial number exactly as shown.
• Compare the serial/date code format to the identification details in the 107277680 owner's manual.
• If the label is missing or unreadable, use the manual’s illustrated parts sections to confirm you have the correct mower family (ZTS 7500, 42-inch deck).

What the model number tells you (and what it does not)

The model number confirms the mower platform and major configuration, but not a single production year.

What you have	What it confirms	What you still need for the year
Model number: 107277680	ZTS 7500 rear-engine rider platform	Serial/date code from the ID tag
42-inch deck references	Deck size and related assemblies	The manufacturing date on the label
Briggs & Stratton 19 HP	Engine family used on this configuration	Engine date code (optional cross-check)

Why it matters

Knowing the exact year helps us match the correct parts diagrams, hardware, and deck or control group components so you order parts that fit the first time (for example, deck hardware like the carriage bolt 703185 or deck height components).

Quick parts cross-check (optional)

If you are confirming you have the 42-inch deck setup used on this model, these parts are commonly tied to the deck and support groups:

• Lawn tractor deck height adjuster crank 1727681SM
• Craftsman lawn tractor blade idler pulley arm 1732502ASM
• Rod hitch m 1713578SM
• Chute deflector 94707MA
