EPR Deck Rebuild Kit Compatible with John Deere 42 Inch 105 115 D100 D105 D110 D120 D130 LA100 LA105 LA110 LA115 LA120 LA125 LA135 S100 S120 S130

What It Is

This EPR Deck Rebuild Kit replaces all wear-prone components on a 42-inch John Deere mower deck—spindles, belts, pulleys, and hardware—to restore cutting performance and eliminate vibration or uneven cuts. Designed for residential John Deere models with Edge™ or standard stamped-steel 42-inch decks.

Fitment & Compatibility

• Deck size: Only fits John Deere 42-inch (107 cm) decks. Measure your deck width from blade tip to blade tip; if it’s 42 inches, this kit fits.
• Models: Compatible with 100-series (105, 115), D100–D130, LA100–LA135, and S100–S130. Double-check your model tag under the seat or on the frame.
• OEM vs. aftermarket: EPR is a third-party kit, not John Deere genuine. It uses aftermarket spindles, belts, and pulleys. Works as a direct replacement but may differ slightly in bearing quality or belt length tolerance.
• What to verify: Ensure your deck has the standard 5/8-inch spindle shaft and single-belt drive (most 42-inch decks from 2000 onward). If you have a “Quick Spindle” design or dual-belt system, this kit won’t fit.

Key Things to Know

• Quality: Bearings are sealed and pre-greased—good for 2–3 seasons under normal use. Some users report belt tension is slightly tighter than OEM; adjust the idler arm accordingly.
• Installation difficulty: Moderate. Requires removing the deck, disassembling spindles, and replacing belts/pulleys. Expect 2–3 hours with basic hand tools (socket set, pry bar, torque wrench).
• Common gotchas: The kit includes new blade bolts—use them. Old bolts may be worn or stripped. Also, check that the spindle housings are not bent before installing; if they are, buy separate spindles (not included).
• Included parts: 2 spindle assemblies, 1 drive belt, 2 pulley sets, blade bolts, and hardware. Does not include blades, idler pulleys, or deck wash fittings.

Should You Buy It

Yes, if your John Deere 42-inch deck has worn spindles (noisy, wobbling) or a slipping belt, and you want a cost-effective, all-in-one refresh without buying OEM parts individually. Not ideal for heavy commercial use or if you need exact OEM tolerances—genuine John Deere spindles may last longer but cost 2–3x more. Good for DIY homeowners who want to restore cut quality for $100.
