Troy-Bilt Mower Parts: Wheels, Blades, Spindles and Starters

Best for
TB210 to TB270ES self-propelled mowers

The Set of 2 Front Drive Wheels from ZALANA replaces part numbers 734-04018, 734-04018A, 734-04018B and 734-04018C, plus 12AV569Q597. The listing names Troy-Bilt TB210, TB230, TB240, TB250, TB270ES and the Tuff-Cut 210, along with a long run of 12A-series model numbers such as 12A-264U011, 12A-446A011 and 12A-466M011.

The wheels are rubber with a 53-tooth drive gear, 8 inches in diameter and 2-1/8 inches wide, with a 1-3/8 inch hub offset and a 1/2 inch bore. Worn gear teeth are a common reason a self-propelled mower suddenly stops pulling, even when the belt and transmission are fine, so replacing both front wheels at once is a sensible fix. Installation is a hex nut off, old wheel off, new wheel on.

ZALANA offers a 6-month warranty. This suits owners of front-wheel-drive TB models whose wheels have worn or cracked. Check the offset and bore on your old wheel if your model is not listed.

• Replaces 734-04018, A, B and C
• 8 in. diameter, 2-1/8 in. width, 1/2 in. bore
• 53-tooth drive gear
• Set of two, 6-month warranty

Best for
21-inch push mowers missing a chute

The Lawn Mower 731-07486 Side Discharge Chute from DECKMAN replaces part 731-07486 on many 21-inch push mowers. The Troy-Bilt models named include the TB110, TB130, TB220 and TB230, plus 11A and 12A series numbers like 11A-A23N011, 11A-A26M011 and 11A-B29Q711.

The chute is black plastic, 11 inches along its longest side and 3.4 inches tall, weighing 0.23 kg. Screws are not included, so keep the ones from your old chute. The seller also lists models it does not fit, including 12AEB2JA001 (2011), 12AVD39Q701 (2011) and 12A-A03M700 (2012 and 2013), and warns that dimensions can vary by year.

This suits push-mower owners who side-discharge tall grass and need a replacement for a snapped chute. Measure your old one against the listed dimensions before buying.

• Replaces 731-07486
• 11 in. long, 3.4 in. tall
• Plastic, reuse your old screws
• Excluded models listed

Best for
21-inch decks needing a 3-in-1 blade

The Grasscool 942-0741A Troy Bilt 21 inch Mulching Blade replaces a long list of part numbers, including 942-0741, 942-0741A, 742-0741, 742-0741A and 742-04276. It fits 21-inch decks on walk-behind, push and self-propelled mowers, and the Troy-Bilt list includes the TB105 through TB270 ES range, Tuff-Cut 200 to 230, Pro-Cut 300 to 320 and TB449E.

It is a 3-in-1 blade for mulching, bagging and side discharge, made from 40MnB steel. It measures 20-7/8 inches long, 2-1/4 inches wide and 9/64 inch thick, with a bow-tie center hole and a 1-1/8 inch lift. Grasscool says the airflow helps it handle damp grass without clogging and lift seed heads off weedy lawns.

This suits any 21-inch Troy-Bilt owner with a dull or damaged blade. Always disconnect the spark plug wire before removing a blade, and balance the new one if you sharpen it later.

• Replaces 942-0741A, 742-0741 and more
• 40MnB steel, 20-7/8 in. long
• Bow-tie center hole, 1-1/8 in. lift

Best for
Pony, Bronco and TB42 42-inch decks

The 918-06991 618-06991 Spindle Assembly Fit from JYLEYJParts is the one part here for riding mowers. It comes as a two-pack and replaces 918-06991 and 618-06991. Troy-Bilt fitments include the Pony 42, Bronco 42, Colt XP 42, TB42 and TB2246 with 42-inch decks.

A worn spindle shows up as grinding noise, a wobbling blade or an uneven cut on one side of the deck. Replacing both spindles at the same time keeps the deck balanced. The package measures 12.32 x 7.87 x 6.38 inches and weighs 9.77 pounds. The listing does not give bearing or shaft specs.

The seller says each unit passes inspection and invites contact for problems within a year. This suits 42-inch Troy-Bilt riders only. If you are thinking about retiring the rider altogether, our look at a GPS robot lawn mower shows what a hands-off yard looks like.

• Replaces 918-06991 and 618-06991
• Two spindles per pack
• Fits Pony 42, Bronco 42, TB42
• One-year seller support

Best for
Switching 21-inch mowers to mulching

The Hinged Mulch Plug 987-02516A Compatible from yewposy replaces part numbers 987-02516A, 987-02516, 687-02516 and 687-02516A. It fits 21-inch mowers, with Troy-Bilt models named including the TB110, TB130, TB210, TB230, TB250, TB270ES, TB280ES, TB320, TB330XP and TB350XP.

A mulch plug blocks the rear discharge opening so clippings stay under the deck and get cut again, then fall back into the lawn. The hinged design lets it flip out of the way when you want to attach a bag. It measures 8.5 x 6.5 x 0.5 inches and weighs 7.8 ounces.

This suits anyone who lost their original plug or wants to start mulching. Pair it with the 3-in-1 blade above for the best mulching results.

• Replaces 987-02516A and 687-02516
• Hinged design
• Fits many 21-inch TB models
• 8.5 x 6.5 x 0.5 inches

Best for
TB110 and TB200 pull-start repairs

The 593959 591139 Recoil Starter for Troy Bilt mowers, from Kuupo, replaces 593959, 591139, 593961 and 590588. It fits Troy-Bilt TB110, TB115, TB200 and TB554, and engines in the 450E, 500E, 550E, 550EX, 575EX, 600E and 625E series, along with 08P502, 093J02, 09P602 and 09P702, in 125cc to 150cc sizes.

The listing gives useful dimensions: 50 x 183 mm overall, mount holes about 5.5 mm in diameter and about 172 mm apart, and a 57 mm core. The seller asks buyers to verify engine model and part numbers before ordering.

This suits owners whose pull cord will not rewind or will not catch the flywheel. It is one of the simplest mower repairs: a few bolts on top of the engine. Compare the mount hole distance with your old starter before buying. If you would rather skip pull starts entirely, our review of a robot lawn mower is worth a look.

• Replaces 593959, 591139, 593961, 590588
• Fits TB110, TB115, TB200, TB554
