Common failure areas on this model

The confirmed parts above group into a handful of failure areas. Here is what each points to and how to check it before you order anything.

General hardware and mounting parts

Symptom: A small mechanical or mounting part has failed, cracked, or gone missing.

Check: Compare the physical shape and mounting points to the original piece, and confirm the exact part number against your model plate before ordering.

Parts in this group on 17BSDALC099: 70310388A (Craftsman BRKT-TANK SU), 70310142A4021 (PLT-TANK SUP), 93111558 (Console), 94204416 (Lawn Tractor 54-in Deck Mulching Blade), 19A70038OEM (Lawn Tractor Mulch Kit), 777S35911 (Decal), 70309320F (FRAME-SEAT B), 777S35683 (LABEL-SAFETY), 9253233A (Lawn Tractor Blade Engagement Switch), 70309211A (Troy-Bilt Brkt-Lapbar), 703077874028 (Lawn Tractor Mandrel Plate), 92506221B (METER-SVC MN), 91806993A (MTD Lawn Tractor Mandrel Assembly), 72506102A (Switch Key), 9320264 (Lawn & Garden Equipment Flat Washer), 72504363 (Lawn Tractor Interlock Switch), 62504124 (Lawn Tractor Ignition Key), 73404155 (MTD Lawn Tractor Gauge Wheel), 71404040 (MTD Lawn & Garden Equipment Cotter Pin, 1/4- to 5/16-in), 71204063 (Yard Machines Lawn & Garden Equipment Lock Nut, 5/16-18), 71204065 (MTD Yard Machines Lawn Tractor Flange Nut).

Storage, trim and cosmetic hardware

Symptom: A cracked shelf, broken door bin, worn hinge, or missing trim piece -- cosmetic and storage wear rather than a functional breakdown.

Check: Match the physical dimensions and mounting tabs of the old part before ordering; these pieces are often model-specific even between visually similar models.

Parts in this group on 17BSDALC099: 70310312 (MTD Rear Bracket), 90305096B4028 (Lawn Tractor 54-in Deck Housing (Sears Yellow)), 70309352A (COVER-DECK B), 7100599 (MTD Lawn Tractor Screw).

Drive system (belts, pulleys, motors)

Symptom: A drum or tub that won't turn, a burning-rubber smell, or a loud thump or squeal during a cycle.

Check: With power off, turn the drum or tub by hand -- resistance or grinding points to the motor or a bearing, and a cracked, glazed, or snapped belt is visible once the cabinet is open.

Parts in this group on 17BSDALC099: 90305266 (Lawn Tractor Blade Idler Pulley Arm), 75604487 (Lawn Tractor Blade Idler Pulley, 6-in), 72104516 (Pulley Cap), 70309352A0691 (Lawn Tractor Blade Drive Belt Cover), 75604459A (Pulley).

Before you buy

Match 17BSDALC099 exactly against the model and serial plate on the appliance itself before ordering anything — a single mismatched character can point to a different production run with different parts. Then check the part number printed or stamped on the part you are replacing against the part numbers in the table above; the printed number is the most reliable way to confirm fitment when a model has gone through multiple production runs. RepairKitHub does not sell parts directly — every part link above routes to an Amazon search for that part number so you can compare current listings and sellers yourself.

How to confirm this is your model

Check inside a door opening, on a back or side panel, or behind a removable panel or drawer for a label printed with the model and serial number. Match every character exactly, including letters and dashes at the end — appliance model numbers often have similar prefixes but different suffixes for different production runs.

Still not sure?

Use the model lookup tool to search by model or part number, or start from the symptom your appliance is showing.
