Replacement Battery Bracket BatteryHold Down Assembly Fits John Deere 100 200 300 400 Series Riding Lawn Mower Tractors

What It Is

This replacement battery hold-down assembly secures the battery in place on John Deere 100, 200, 300, and 400 Series riding lawn mower tractors. It prevents battery movement during operation, reducing vibration damage and terminal corrosion.

Fitment & Compatibility

Before buying, verify your tractor model number (e.g., D100, X300, LA145). This assembly fits most 100–400 Series models from the late 1990s through 2010s, but not all—check if your original bracket uses a single rod or two-piece clamp. Measure your battery’s length and width: this bracket fits standard Group U1 batteries (roughly 7.7” x 5.1”) but may not accommodate larger or odd-sized batteries. OEM part numbers to cross-reference include AM107520, AM130725, and GY20579. If your tractor has a side-mount battery tray (common on later 300 Series), this might require additional hardware or not fit at all.

Key Things to Know

• Quality concerns: With a 3.0 rating from only 3 reviews, expect thin metal or poor fitment on some models. The rods may bend under heavy vibration.
• Installation difficulty: Easy—about 10 minutes with basic hand tools. You’ll need a 10mm socket or wrench for battery terminals and bracket bolts.
• Common gotcha: The included hardware (bolts, nuts) may be metric while your tractor uses SAE. Have a tap/die set or replace with your original bolts if threads don’t match.
• Missing parts: Some buyers report missing J-bolts or wing nuts. Check the package contents immediately upon arrival.

Should You Buy It

This is a budget-friendly choice if you need a quick replacement and your original bracket is rusted or broken, but only if you’re comfortable with potential fitment issues and lower build quality. For a more reliable, longer-lasting hold-down, consider spending $5–10 more on an OEM or heavy-duty aftermarket option.
