Replace a Worn Hydro Pump Belt
A stretched, cracked, glazed, frayed, or damaged hydro pump belt can slip on the pulleys and interrupt power transfer to the hydraulic drive system. Common symptoms can include reduced drive response, inconsistent movement, squealing, or a mower that will not move even though the engine is running.
Why Choose a Genuine Exmark OEM Hydro Belt?
Hydro pump drive belts must have the correct length, profile, strength, and flexibility to operate properly within the mower’s drive system. The Exmark 115-9613-SL is manufactured for its specified pulley arrangement and tensioning system, helping maintain reliable hydro pump operation without modification.
Important: Verify your model and serial number before ordering. Exmark frequently uses different hydro pump drive belts across similar mower models, and fitment can vary by serial number.
