4 Pack GX10168 Deck Wheels Replace John Deere GX10168 Gauge Wheels for John Deere 115 D100 D105 D110 D130 D140 D160 D170 L100 L110 L120 L130 LA115 LA135 LA145 Z345R Z355E Z425 Z445 Z540M Deck

What It Is

This 4-pack of GX10168 replacement gauge wheels helps stabilize the mower deck on John Deere lawn tractors and zero-turn mowers, reducing scalping on uneven terrain. Designed for 42” to 54” decks, they’re a direct aftermarket substitute for OEM part GX10168.

Fitment & Compatibility

Before buying, confirm your deck size and model. Fits John Deere D100–D170 series, L100–L130 series, LA115–LA145, and Z345R, Z355E, Z425, Z445, Z540M. Also fits select 100-series and X300 models with GX10168 wheels. Measure your existing wheel’s outside diameter (should be ~6.5”) and axle hole size (0.5”). These are aftermarket, not OEM, so check that your deck uses a single bolt/washer retention—some older models may need a different shoulder bolt length. Verify your deck has four mounting holes (two per side) for a full set.

Key Things to Know

• Quality: Durable plastic with steel bearings; holds up on residential lawns but may wear faster on rough, rocky terrain.
• Installation: Simple—remove the retaining bolt, swap the wheel, and re-tighten. No special tools needed. Takes ~10 minutes for all four.
• Common gotcha: The included bolts may be slightly too short for decks with thick brackets; reuse your original hardware if needed.
• Fitment note: Not compatible with older 300-series or LX models that use different wheel designs (e.g., GY20578).

Should You Buy It

Buy this if you need a budget-friendly, drop-in replacement for worn or missing gauge wheels on a compatible John Deere lawn tractor or ZTR. It’s a solid value for residential use, but if you mow commercially or on very rough ground, consider OEM for longer life.
