Procedure for Reel Motor Case Drain Check:

1.Make sure hydraulic oil is at normal operating tem- perature by operating the machine for approximately 10 minutes. Make sure the hydraulic tank is full.

2.Make sure machine is parked on a level surface with the cutting units lowered. Make sure engine is off and the parking brake is engaged.

CAUTION

Operate all hydraulic controls to relieve system pressure and avoid injury from pressurized hydraulic oil.

3.On suspected bad motor, clean hose connection and disconnect hose from motor that returns to the man- ifold (see table).

IMPORTANT: Make sure oil flow indicator arrow on the flow gauge is showing that the oil will flow from the motor through the tester and into the hose.

4.Install tester in series with the motor and the discon- nected return hose. Make sure the flow control valve is fully open.

5.Make sure backlap knob on the valve block is in the mow position.

6.One person should sit on the seat and operate the machine while another person reads the tester. Start en- gine and move the throttle to full speed (3200  100 RPM).

CAUTION

Keep away from reels during test to pre- vent personal injury from the rotating reel blades.

7. Engage reels by pulling the knob on the instrument panel out. While watching pressure gauges, slowly close flow control valve until a pressure of 1200 PSI is obtained.

8. Disengage cutting units and stop engine.

 

9. Clean hose fitting and disconnect hose from case

 

drain on the manifold block (see table). Plug the man-

 

ifold port.

 

10. Put case drain hose into 1 quart container gra-

 

duated in ounces (1 liter container graduated in millili-

 

ters).

 

11. One person should sit on the seat and operate the

 

machine while another person holds the hose and reads

 

the tester. Start engine and move the throttle to full

 

speed (3200  100 RPM).

12. While sitting on seat, engage cutting units by pulling

 

the knob on the instrument panel out. Make sure gauge

 

pressure still reads 1200 PSI. After 15 seconds, push

 

knob on the instrument panel in to disengage cutting

 

units. Stop the engine.

 

 

13. Measure the amount of oil collected in the container.

 

Divide the number of ounces collected by 32 to get gal-

 

lons per minute. (Divide the number of milliliters col-

 

lected by 250 to get liters per minute).

 

14. Disconnect tester from motor and hose. Reconnect

 

hose to the pump.

 

15. Remove cap from manifold fitting. Reconnect case

 

drain hose to the motor.

 

16. If flow was greater than 0.7 GPM (2.6 LPM), repair

 

or replace the reel motor as necessary.

Toro 2600D, 2300-D service manual Procedure for Reel Motor Case Drain Check

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.
