Traction (Electric) Clutch

Note: When disconnecting the clutch, use the electri- cal connector that connects the clutch directly to the wir- ing harness. Do not use the connector attached to the traction clutch switch. This connector contains a diode in the circuit which will give incorrect resistance read- ings

Deenergized Testing

Note: Prior to taking small resistance readings with a digital multimeter, short the test leads together. The me- ter will display a small resistance value (usually 0.5 ohms or less). This resistance is due to the internal re- sistance of the meter and test leads. Subtract this value from from the measured value of the component you are testing.

1.Disconnect the clutch electrical connector from the wiring harness.

2.Using a digital multimeter, measure the resistance between the connector terminals. The resistance should be from 3.0 to 4.0 ohms.

3.Connect the clutch electrical connector to the wiring harness.

Note: Low resistance may be accompanied by the 10 amp engine fuse blowing from drawing high current. High resistance may be accompanied by the clutch not engaging from drawing insufficient current.

Live Testing

1.Disconnect the clutch electrical connector from the wiring harness.

2.Connect a 12 VDC source across the electrical con- nector terminals. The clutch should engage with a dis- tinct audible ºclickº.

3.Disconnect the 12 VDC source from the connector terminals.

4.Connect the clutch electrical connector to the wiring harness.

Traction (Neutral) Interlock Switch

The traction interlock switch is normally open and closes when the traction pedal in in the neutral position.

1.Disconnect the electrical connector to the switch.

2.Check the continuity of the switch by connecting a multimeter (ohms setting) across the connector termi- nals.

3.With the engine off, slowly push the traction pedal in the forward and reverse direction while watching the multimeter. Continuity should be broken in the forward and reverse directions.

4.Allow the traction pedal to return to the neutral posi- tion. There should be continuity across the terminals.

5.Reconnect the electrical connector to the switch.

2600D, 2300-D specifications

The Toro 2300-D and 2600-D are industry-leading reel mowers specifically designed for the professional turf care market. Known for their durability, efficiency, and advanced technology, these models provide exceptional cutting performance for golf courses, sports fields, and other high-quality turf applications.

One of the standout features of the Toro 2300-D and 2600-D is their powerful engines. Powered by efficient diesel engines, these mowers deliver robust performance while being fuel-efficient. This capability ensures extended operation periods, allowing grounds crews to maintain pristine conditions across large areas without frequent refuelling stops.

Both models are equipped with Toro’s exclusive DPA (Dual Precision Adjust) cutting system, providing precise cutting heights for optimal turf health. This system allows for adjustments from 1/8 inch to 1 inch, enabling operators to achieve the correct level for various grass types and turf conditions. This level of precision ensures a clean cut and promotes the overall health of the grass.

Another notable characteristic is the ergonomic design, which includes a comfortable operator station to reduce fatigue during extended use. The controls are intuitively located, enabling easy access and operation, and the mower's compact design allows for nimble maneuverability around obstacles, ensuring that every inch of turf can be accurately maintained.

In terms of technology, the Toro 2300-D and 2600-D feature advanced traction control systems that provide excellent grip and stability on slopes and uneven terrain. The lightweight alloy construction of the frame contributes to this stability, giving operators confidence whether they are working on flat surfaces or more challenging landscapes.

Furthermore, these mowers are designed with sustainability in mind. The diesel engines not only offer efficiency but also are compliant with strict emissions standards, making them an environmentally responsible choice for turf maintenance.

The Toro 2300-D and 2600-D also feature a robust maintenance management system that alerts operators of necessary maintenance tasks, promoting longer lifespans for components and enhancing overall performance.

In summary, the Toro 2300-D and 2600-D deliver cutting-edge technologies and features, including powerful engines, versatile cutting systems, ergonomic design, advanced traction control, and sustainability focus. These models represent the pinnacle of reel mower engineering, making them ideal choices for professionals dedicated to maintaining the finest playing surfaces.
