Oregon 76-031 Trunion Lift Lawn Mower Deck Part

What It Is

The Oregon 76-031 Trunion Lift is a replacement pivot bracket for the lift mechanism on EGO lawn mower decks. It connects the deck height adjustment rod to the deck, enabling smooth raising and lowering of the cutting deck.

Fitment & Compatibility

Before buying: Verify your EGO mower model number (found on a sticker under the battery compartment or near the rear wheels). This part fits select EGO 21-inch and 56-volt mower models—common compatible models include LM2100, LM2101, LM2102SP, and LM2135SP. It does not fit 20-inch or older 56V models without the trunion-style lift. Measure the original trunion’s shaft diameter (should be ~8mm) and overall length (~50mm) to confirm match. Oregon markets this as an aftermarket replacement for OEM part number 282623100.

Key Things to Know

• Quality: Molded nylon with steel insert—durable but not indestructible. Replace if cracked or worn, as a broken trunion causes uneven deck height.
• Installation: Easy—remove the hairpin clip, slide out the old trunion, insert the new one, and reinstall the clip. No tools required beyond a small flathead screwdriver to pry the clip.
• Gotcha: The trunion can bind if the deck is rusted or debris-packed. Clean the pivot area before installing.
• Gotcha: Some users report slight looseness vs OEM—this is normal for aftermarket parts and doesn’t affect function.

Should You Buy It

If your EGO mower’s deck height adjustment feels sticky, uneven, or won’t stay set, and you’ve confirmed model compatibility, this $10.47 part is a cheap, easy fix. It’s ideal for DIYers who want to avoid a $60+ OEM replacement and don’t mind a slightly looser fit that still works perfectly.
