John Deere LT133

The John Deere LT133 is a lawn tractor that was manufactured from 1998 to 2001 in Horicon, Wisconsin, USA. It was powered by a 13 HP Kohler 398cc single-cylinder gasoline engine and featured a 5-speed gear transmission. The tractor had a wheelbase of 46.3 inches (117 cm) and weighed between 392 to 455 pounds.

The LT133 was equipped with a 2-gallon (7.6 L) fuel tank and had an open operator station with manual steering and disc brakes. It came with a mid-mount Power Take-Off (PTO) and a manual clutch. The front tires were 15×6.00-6, while the rear tires were 20×10.00-8.

This model was designed for residential use and came with various attachments. The primary attachment was a 38-inch mid-mount mower deck with two blades. Other available attachments included a snowblower and a blade for added versatility.

A unique feature of the LT133 was its availability in a Motorsports edition, which included special decals and a certificate signed by John Deere-sponsored NASCAR driver Chad Little.

The original price of the LT133 in 1997 was $1,999. The serial number for this model can be found on the tractor body, below and in front of the seat. The serial numbers started at 010001 for the 1998 model year and increased annually.

Maintenance for the LT133 included regular oil changes, with recommendations against using oils with heavier viscosity weights than SAE 5W-30 or oils meeting specifications API SG or SH, as these could potentially cause issues with the engine.

While the LT133 is no longer in production, it remains a popular model among John Deere enthusiasts and continues to be used by homeowners for lawn care and light garden work.

John Deere LT133 Drive Belt Diagram

Drive Belt Configuration

The John Deere LT133 lawn tractor uses a drive belt system to transfer power from the engine to the transmission and mower deck. The drive belt diagram for the LT133 is as follows:

Engine Pulley

The drive belt starts at the engine pulley, which is typically located at the front of the tractor. This pulley is connected directly to the engine crankshaft.

Idler Pulleys

From the engine pulley, the belt routes through a series of idler pulleys. These pulleys help guide the belt and maintain proper tension. The LT133 typically has two to three idler pulleys in its drive system.

Transmission Pulley

After passing through the idler pulleys, the belt connects to the transmission pulley. This pulley is responsible for transferring power to the transmission, which then drives the wheels.

Belt Tensioner

The LT133 is equipped with a spring-loaded belt tensioner. This component helps maintain proper belt tension and compensates for belt stretch over time.

Belt Path

The belt follows a serpentine path around the pulleys:

  1. Engine pulley

  2. First idler pulley (usually located near the front of the tractor)

  3. Second idler pulley (typically positioned towards the middle of the tractor)

  4. Transmission pulley

  5. Belt tensioner

  6. Back to the engine pulley

Important Notes

  • The flat side of the belt should make contact with flat idler pulleys.

  • The grooved side of the belt should align with grooved pulleys (typically the engine and transmission pulleys).

  • Ensure the belt is not twisted when installing.

Maintenance Tips

  • Regularly inspect the belt for wear, cracks, or fraying.

  • Keep pulleys clean and free of debris.

  • Check and adjust belt tension as specified in the owner’s manual.

When replacing the drive belt, always refer to the specific model number of your John Deere LT133, as there may be slight variations in belt routing depending on the production year and any modifications made to the tractor.
