731-12350B Left Hand Bagger Support Cover for CUB Cadet MTD Riding Lawn Mowers Double Bagger 42" 46" Deck LTX1045 LTX1046 LTX1042 LTX1040 LTX1046VT XT1-LT46 and 50" Cub Cadet

What It Is

The 731-12350B is the left-hand bagger support cover for Cub Cadet and MTD riding mowers with a double-bagger system. It mounts on the left side of the mower deck to secure the bagger chute and support the grass collection bag, used on 42" and 46" decks (and some 50" models) for grass collection during mowing.

Fitment & Compatibility

• Deck size: Fits 42", 46", and 50" decks—double-check your deck width stamped on the mower frame or deck shell.
• Models: Works with Cub Cadet LTX1040, LTX1042, LTX1045, LTX1046, LTX1046VT, XT1-LT46, and similar MTD-built models. Also fits some 50" Cub Cadet models with the double-bagger kit.
• OEM vs aftermarket: This is an OEM Cub Cadet part (OEM #731-12350B). Aftermarket copies may have slightly different hole spacing or thinner plastic—stick with OEM for a guaranteed fit.
• Check before buying: Verify your bagger is the factory double-bagger (two bags, left and right). Single-bagger systems use a different support. Measure the distance between mounting holes on your deck frame—should be about 6–7 inches apart.

Key Things to Know

• Build quality: Made from durable black plastic, but can crack if over-tightened or hit by debris. Inspect for stress marks before installation.
• Installation: Easy—no special tools needed. Two bolts secure it to the deck frame. Takes 10–15 minutes if you have a socket set.
• Common gotcha: The left-side support often gets bent or broken when the mower hits a tree root or curb. If your bagger chute sags or rubs the tire, this cover is likely the culprit.
• Price note: At $66, it’s mid-range for this part. OEM replacements typically run $50–$80. A cracked cover can cause the bagger to detach during operation, so don’t delay replacement.

Should You Buy It

Buy this if your left bagger support cover is cracked, missing, or bent, and you want a direct OEM fit for your Cub Cadet or MTD double-bagger mower. It’s a simple, reliable fix—skip it only if you’ve switched to a single-bagger or a third-party bagger system that uses different mounting hardware.
