42″ Toro TimeCutter SS, SW, MX & SWX with V-Twin Engine Tune-Up Kit

We design Toro Tune-Up Kits to simplify maintenance of TimeCutter Zero Turn Riding Mowers. Full Synthetic Kit (853151007370) includes Genuine Toro parts to re-power engine and renew blades (2 blades, air filter, fuel filter, spark plugs, oil filter, full synthetic oil and fuel stabilizer). Authentic Toro parts maintain consistent performance and assure easier installation.

All our our tune up kits include the latest recommended parts to perform a simple tune up. Toro updates part numbers and may change recommendations based on testing and in field results. The items offered in this kit may vary from the original part numbers.

Please verify that your model is listed in the compatible models and contact us directly with questions prior to purchase. Customized kit fits specific 42 IN Toro TimeCutter SS, SW, MX & SWX with V-Twin Engine Tune-Up Kit. Toro Full Synthetic Oil included in kit 139-0646 is designed for extreme temperatures, everyday conditions and outstanding anti-scuff protection with added zinc and phosphorous. These fluids protect your engine across a broader range of temperature than standard oil available in other kits.

Please Note: Inspect condition of pump belt, deck belt and blade bolts when installing tune up kit. Changing these components may prevent unnecessary breakdown.
