CARE AND MAINTENANCE

PROCEDURE FOR ELECTRIC CLUTCH ADJUSTMENT

Electric clutches require periodic Air Gap adjustments to extend the life of the clutch. Listed below is both an Air Gap adjustment procedure and an Ohms test to check for a faulty coil within the clutch. No replacement parts are available to repair a faulty assembly. The entire clutch must be replaced.

A. AIR GAP ADJUSTMENT

1.Remove the clutch from the engine. This is recommended because it is easier to verify the gap-

2.Locate the three rivet joints which fasten the leaf springs to the armature, (figure 1)

3.Rotate the pulley until these rivet joints are located midway along the edge of the triangular field adapter, (figure 1)

4.Locate the three holes in the brake plate, one near each adjustment nut. (figure 2)

5.Insert a .012 inch feeler gauge into one of the three windows. Be careful to position the feeler gauge between the rotor and armature faces, (figure 3)

6.Tighten the adjusting nut adjacent to the window with the feeler gauge inserted until the gauge fits snugly between

the rotor and armature. The gap should not be so tight that the feeler gauge cannot be reinserted after removal.

7.Repeat Steps 5 and 6 at the other two windows.

8.Re-check the air gap at each window and make minor adjustments as necessary to achieve a consistent

.012 inch air gap.

9.Reinstall the clutch to the engine. Be sure to torque the mounting bolt back to 50 ft. Ibs.

B.OHMS TEST:

1.Disconnect clutch from mower wiring harness which is located on the right side of the mower frame.

2.Set the multi-meter on RX1 and attach the two leads to the two wires coming from the electric clutch.

3.The reading you receive should be between 2.4 to 2.9 OHMS.

4.If the resistance is outside this range the clutch coil is faulty.

5.If the clutch coil is faulty, the clutch must be replaced.

ZTR 5424, ZTR 5020 specifications

The Dixon ZTR 5424 and ZTR 5020 are prominent models in the world of zero-turn mowers, known for their reliability, cutting efficiency, and user-friendly features. These mowers are designed for both residential and commercial use, providing exceptional maneuverability and performance.

The Dixon ZTR 5424 is equipped with a powerful 24-horsepower engine, offering robust performance and ample power for cutting through tough grass and uneven terrain. With its wide 54-inch cutting deck, this model allows for efficient mowing over large areas, minimizing the time required to complete yard work. The deck is crafted with heavy-duty materials to ensure durability, while the adjustable cutting height makes it versatile for different grass types and seasons.

On the other hand, the ZTR 5020 features a slightly smaller engine, typically around 20 horsepower, making it ideal for residential users with medium-sized yards. The 50-inch cutting deck strikes a balance between capability and maneuverability, allowing users to navigate tight corners and landscaping features with ease. Both models utilize a dual-blade design, which enhances cutting efficiency and improves grass discharge, ensuring a well-manicured lawn.

One of the standout technologies found in both models is the hydrostatic transmission, providing smooth acceleration and seamless speed adjustments. This technology allows operators to control the mower with precision while eliminating the need for shifting gears, making mowing more enjoyable. Additionally, the zero-turn design allows for the impressive turning radius, enabling users to make sharp turns around obstacles without leaving uncut patches.

User comfort is also a priority in the design of both mowers. Equipped with ergonomic seats that reduce fatigue during extended use, the ZTR 5424 and ZTR 5020 ensure a comfortable riding experience. Easy-to-reach controls, including adjustable steering levers and intuitive dashboard features, enhance operational ease.

In summary, both the Dixon ZTR 5424 and ZTR 5020 provide powerful performance, efficient cutting capabilities, and user-friendly features. Whether for commercial or residential use, these mowers are well-suited to meet the demands of various mowing environments. With their combination of technology, comfort, and durability, the Dixon ZTR series continues to be a popular choice among lawn care professionals and homeowners alike.
