Caltric 42" Deck Caster Wheel Compatible with Exmark Quest E-Series/Quest S-Series Zero-Turn Mower/Qty 2

What It Is

This is a pair of aftermarket caster wheels for the 42-inch cutting deck on Exmark Quest E-Series and Quest S-Series zero-turn mowers. These wheels support the front of the deck, allowing it to float over uneven terrain without scalping the grass.

Fitment & Compatibility

Before buying, confirm your mower is an Exmark Quest E-Series or Quest S-Series with a 42-inch deck. Measure the existing wheel diameter (these are 8-inch), spindle hole diameter (typically 1/2-inch), and the stem length. Check that the wheel’s mounting bracket matches your deck’s bolt pattern—Caltric wheels often use a standard two-bolt pattern, but verify against your OEM part number (Exmark OEM numbers include 1-523046 or 103-6936). These are direct replacements for worn or damaged factory wheels, not universal fit.

Key Things to Know

• Quality: Caltric is a budget aftermarket brand. Expect solid construction for residential use, but they may not last as long as OEM under heavy commercial duty.
• Installation: Simple bolt-on swap—remove the old caster, slide in the new one, and tighten. No special tools needed, but check that the stem fits snugly into the deck bracket.
• Gotcha: Some users report the included hardware (bolts/nuts) doesn’t match the Exmark thread pitch. Keep your original bolts or buy grade-8 replacements.
• Quantity: Sold as a pair, so you get both deck casters at once—good for matching wear.

Should You Buy It

This is a good buy if you have an Exmark Quest 42-inch zero-turn and need a budget-friendly, quick replacement for worn or broken deck casters. It’s a direct fit for the specified models, but if you mow commercially or want maximum longevity, consider spending more on OEM Exmark wheels. For homeowners, this is a solid value.
