John Deere TCU19900 Replacement: Compare 2 Options

How to find your model number

Check your model number before you buy a replacement for the TCU19900. On a riding mower or lawn tractor the model and serial label is usually under the seat, on the frame beside the seat, or near the battery. Deck parts may also need the deck size, which is often on a decal on top of the deck.

• Briggs & Stratton engines: the model, type and code numbers are usually stamped on the engine shroud or on a sticker on the blower housing.
• Kohler engines: a label with the model, specification and serial numbers is usually on the blower housing.
• Honda engines: the engine type (for example GCV160) is usually cast or printed on the engine block, with the serial number nearby.

If the old belt is still readable, the part number is often printed on its back. To measure it, run a cloth tape along the outside of the belt and note its width.

Maker's part vs aftermarket: the TCU19900

John Deere's own TCU19900 is available. 1 brand sells a belt listed as its replacement, including 8TEN.

• Maker's own part: made and sold by the equipment or engine maker (for example John Deere, MTD or Briggs & Stratton). Usually the highest price.
• Aftermarket parts: made by other companies to the same size and fit. Usually cheaper; materials and build quality vary by brand.
• Before you buy: find your equipment's model number (see How to find your model number, above), compare the size of your old part, and confirm the fit on the product page.
