109-2339 – Toro Motion Control Damper (4DJ) (Genuine Toro OEM Control Damper)
The Toro 109-2339 Motion Control Damper (4DJ) is a genuine OEM replacement component designed to provide smooth, controlled movement of the steering levers on compatible Toro and Exmark commercial zero-turn mowers. Engineered to Toro's exact factory specifications, this motion control damper reduces sudden lever movement, minimizes operator fatigue, and improves precision during mowing.
Constructed with a heavy-duty sealed hydraulic damping mechanism, the 109-2339 Motion Control Damper is built to withstand constant use, vibration, and harsh commercial mowing conditions. Replacing a worn damper restores smooth steering response and enhances overall machine control.
