Exmark 116-8117 Wheel Caster BR270KC36 BRS270CKC36000

What It Is

The Exmark 116-8117 is an OEM replacement wheel caster assembly designed specifically for Exmark commercial zero-turn mowers. This part supports the front of the mower deck, allowing smooth pivoting and steering during operation.

Fitment & Compatibility

Before purchasing, verify your mower model matches Exmark’s BR270KC36 or BRS270CKC36000 series. This caster is not universal—it fits only select Exmark 60-inch deck models from the Lazer Z and Quest lines. Check your mower’s serial number against Exmark’s parts lookup tool. The caster includes a wheel, yoke, and axle hardware; measure your existing caster’s bolt pattern and wheel diameter (typically 11 inches) to confirm physical match. Aftermarket alternatives exist but may vary in bearing quality and durability.

Key Things to Know

• Installation difficulty: Moderate. Requires basic hand tools (socket set, wrench) and a jack to lift the mower deck. Expect 30–60 minutes.
• Common gotcha: The caster’s pivot bushing can seize if not greased regularly. Check your old caster for wear—if the yoke is bent, replace the entire assembly, not just the wheel.
• Quality: OEM part, so fitment is guaranteed for listed models. The steel yoke and sealed bearings are built for commercial use, but the price is higher than aftermarket options.
• Single unit: Sold individually. If both front casters are worn, order two.

Should You Buy It

Buy this if you own a compatible Exmark commercial mower and need a direct, no-guesswork replacement that matches OEM specs. It’s overkill for residential mowers or non-Exmark brands—consider aftermarket alternatives if you’re on a budget or have a different deck.
