Toro 110-0549 Hoc Adjustment Knob Lawn Mower

Product Description

The TORO 110-0549 is a height-of-cut (HOC) adjustment knob designed for use on Toro walk-behind lawn mowers and turf maintenance equipment. This knob serves as the operator interface for setting the cutting deck height, allowing the user to select and lock in the desired grass cutting height during mowing operations. It is a direct OEM replacement part intended for installation by lawn equipment technicians or experienced equipment operators performing routine maintenance and parts replacement.

This HOC knob is a common wear and replacement item on walk-behind mowers and similar Toro turf equipment. Over time, knobs can crack, strip, or break from repeated use and exposure to outdoor conditions. Replacing the knob restores proper deck height adjustment function and ensures accurate, consistent cutting height control during operation.

Installation Notes

Installation is typically performed by a small engine or turf equipment technician. Before replacing the knob, disengage the blade, shut off the engine, and remove the ignition key to prevent accidental startup. No special tools are generally required for knob replacement, though needle-nose pliers or a flathead screwdriver may assist with retaining clips or fasteners. Consult the equipment service manual for model-specific disassembly steps.
