Transmission slip feels like the engine revs up but the mower moves slowly or doesn't respond to throttle. The blades may spin but the deck barely creeps forward, or you lose power going uphill. Worn clutch plates, low fluid, or a failing transaxle seal cause this. Don't ignore it—slipping gets worse and can leave you stranded.
The PTO (Power Take-Off) clutch engages the blade spindle when you pull the blade control lever. The transmission clutch (or drive clutch) engages the wheels. Toro mowers have both. If only the drive fails, you need a transmission or transaxle part. If only the blade doesn't turn, the PTO clutch is your issue.
Check the frame or engine housing for the model and serial number. Write both down and search our parts finder. Toro uses different transaxles and clutch designs across model years, so the exact number ensures you get compatible replacement parts.
Minor leaks from loose fill plugs or dipsticks are fixable. Seals and gaskets can be replaced on some models. But if the transaxle case is cracked or internal seals fail, replacement is the safest choice. OEM Toro transaxles are pre-sealed and tested for reliability.

Toro prints the model number on a label or plate on the mower frame near the blade deck, though some models place it on the engine housing or under the seat. Look for a tag showing "Model" or "Model No." and copy the number exactly, including letters, numbers, and dashes. Type it into the model number search to pull up the parts matched to your unit. The model number applies to the entire Toro lawn mower, so it narrows the full catalog to compatible parts across every category, not just transmission or drive parts. Matching by model first helps prevent ordering a part from a similar-looking mower and gets your repair moving sooner.

The right online resources take the guesswork out of a Toro Lawn Mower repair. Repair Clinic's diagnostic articles, part testing videos, exploded-view diagrams, and step-by-step written repair guides walk owners and technicians through each stage from symptom identification to final reassembly. Look up your model number to confirm the correct OEM part before you order.
