HZ Starter Motor for Toro 136-7880 Compatible Zero-Turn Mowers — 708cc V‑Twin Fit, Includes Pinion & Bolts

HZ replacement starter motor for Toro 136-7880 and equivalent part numbers restores reliable electric starting for many Toro/Exmark zero-turn and riding mowers with 708cc V‑twin engines. This heavy-duty replacement starter is designed to fit Toro part numbers 136-7880, 127-9209, 133-1564, 133-9828 and related OEM references used on a wide range of TimeCutter, Exmark, Titan and Z Master machines. It suits mowers fitted with Chinese-made Loincin/2P/LC series V-twin engines (2PP77F, 2P82F, LC2P77F, LC2P82F) producing roughly 22–25.5 horsepower. The unit ships with mounting bolts, two spark plugs for routine maintenance, and the included pinion gear (133-1562), making it a cost-effective alternative to buying a factory starter.

Which mower models and engines will this HZ starter fit?

This starter is compatible with many Toro and Exmark models that use the specified 708cc V‑twin engines. It fits numerous TimeCutter, Exmark Quest and Radius series, Titan and Z Master models, but compatibility depends on the engine source rather than only the mower model number.

• Common Toro models: TimeCutter SS4225, SS4250, SS5000, SS5425, SW4200, SW5000, MX4200, MX5000, MX5050, MX5075, MX6050, ZS4200T, ZS5000 and similar decks (42"–60").
• Exmark fits: Quest QSS708 and Radius E‑Series/S‑Series with 708cc engines listed in OEM references.
• Engine families: Loincin 2PP77F, 2P82F, LC2P77F, LC2P82F V‑twin engines (22–25.5 hp).
• Not compatible with the same mower models powered by Kohler, Honda, Kawasaki, or other engines—verify engine part numbers before ordering.

What parts and accessories come with the starter?

The HZ starter package includes the starter motor preassembled with the pinion gear and the hardware you need for installation. Two OEM-style spark plugs are included for convenience so you can address routine maintenance while replacing the starter.

• Included pinion gear (replaces OEM 133-1562).
• Mounting bolts supplied for direct replacement installation.
• Two replacement spark plugs for maintenance while you're working on the engine.
• No additional solenoids or relay modules unless specified by your mower's wiring harness.

How do I confirm compatibility before installing the HZ starter?

Compatibility is determined by the engine part number and physical mount, not just the mower model. Inspect your engine stamping or parts manual and compare with the referenced Toro/Exmark engine codes and OEM starter numbers shown in this listing.

• Check for Toro starter references: 136-7880, 127-9209, 133-1564, 133-9828, 270360146-0001/0002.
• Verify engine code: 2PP77F, 2P82F, LC2P77F, LC2P82F (708cc V‑twin).
• Compare mounting bolt pattern and electrical connector type with removed starter.
• If your mower uses Kohler, Honda, Kawasaki, or other engines, this part will not fit—even if model numbers match.

What should I expect during installation and performance?

Installation follows standard starter replacement steps: disconnect battery, remove old starter, fit the HZ unit using the supplied bolts, reconnect wiring and test. Once installed, you should have consistent engagement and reliable cranking with the same operating behavior as the OEM unit on compatible engines.

• Basic tools required: wrenches, socket set, and safety gloves.
• Includes mounting hardware to reduce downtime during swap.
• Designed to match OEM mounting dimensions and electrical connections for plug‑and‑play replacements on compatible engines.
• Perform a quick electrical and mechanical check after fitting to confirm secure mounting and wiring.

Who is this for? This HZ starter motor is aimed at lawncare owners, fleet managers and technicians who need an affordable, OEM‑referenced replacement for Toro/Exmark machines using the specified 708cc Loincin V‑twin engines. If your mower’s engine matches the listed part numbers and you want a ready-to-install starter with necessary hardware and spare spark plugs, this kit provides a reliable alternative to expensive dealer parts. Avoid ordering if your mower uses a different engine manufacturer—double‑check engine codes before purchase.
