Caltric 2 Deck Blade Compatible with John Deere D110 D120 D125 D130 La100 La105 (21 3/8" L - 2.6" W)

What It Is

The Caltric 2 Deck Blade is an aftermarket replacement blade for select John Deere lawn tractors with 42-inch or 48-inch decks, designed for cutting grass on residential lawns. It measures 21 3/8 inches long and 2.6 inches wide, making it a direct swap for the OEM blade on these models.

Fitment & Compatibility

Before purchasing, verify your mower’s deck size (42" or 48") and confirm your model is on this list: John Deere D110, D120, D125, D130, LA100, LA105. These blades are not compatible with other John Deere series (e.g., X300, Z500) or non-Deere brands unless deck dimensions match exactly. Measure your current blade length (from center hole to tip) and width—must be 21 3/8" and 2.6" respectively. Check the center hole diameter (typically 7/8") to ensure a snug fit on your spindle. This is an aftermarket part, not OEM, so verify the mounting pattern (usually two aligned holes) matches your deck’s blade adapter.

Key Things to Know

• Quality: Caltric blades are made from hardened steel but may be slightly thinner or lighter than OEM John Deere blades, potentially reducing lifespan in heavy or wet grass.
• Installation: Requires basic tools (socket wrench, torque wrench). Torque blade bolts to 30-40 ft-lbs as specified in your mower’s manual. Over-tightening can strip threads.
• Balance: These blades come pre-balanced, but always check with a blade balancer after installation—an unbalanced blade causes vibration and poor cut quality.
• Sharpness: Blades arrive sharp but not razor-edge. For best results, sharpen after the first few hours of use, then every 10-15 hours of cutting.

Should You Buy It

If you need a budget-friendly replacement for a John Deere D-series or LA100-series mower and don’t mind occasional sharpening, this Caltric blade is a solid choice. It’s not ideal for commercial use or tough conditions (e.g., thick, wet grass), but for typical residential lawns, it offers good value at $40. If you prefer OEM durability or have a larger deck, look for John Deere genuine parts instead.
