Disassembly (Fig. 64)

1.Remove oil from cylinder into a drain pan by slowly pumping the cylinder shaft (6). Plug both ports and clean the outside of the lift cylinder.

IMPORTANT: Prevent damage when clamping the lift cylinder into a vise; clamp on the pivot end only. Do not close vise enough to distort the barrel (1).

2.Mount lift cylinder in a vise so that the shaft (6) end tilts up slightly.

3.Remove retaining ring (11) from the barrel (1).

4.Grasp clevis rod (14); extract shaft (6), head (10), and piston (3) by carefully twisting and pulling on the shaft out from the barrel (1).

IMPORTANT: Do not clamp vise jaws against shaft surface. Protect shaft surface before mounting in the vise.

5.Mount shaft (6) securely in a vise. Remove locknut

(2) and piston (3) from the shaft. Slide head (10) off the shaft.

6.Remove and discard uni±ring (4) and O±ring (5) from the piston (3). Remove and discard dust seal (12), backup washer (9), and O±rings (7 and 8) from the head (10).

Note: If the rod clevis (14) is to be removed from the shaft (6), note the number of threads exposed between the jam nut (13) and the smooth surface of the shaft to help reassembly.

7. Loosen jam nut (13) and remove clevis if necessary.

Inspection (Fig. 64)

CAUTION

Use eye protection such as goggles when using compressed air

1.Wash all parts in solvent. Dry parts with compressed

air.

2.Inspect internal surface of barrel (1) for deep scratches, out±of±roundness, and bending. Replace if worn or damaged.

3.Inspect head (10), shaft (6), and piston (3) for ex- cessive pitting, scoring, and wear. Replace any worn or damaged parts.

Reassembly (Fig. 64)

1.Coat new dust seal, uni±ring, backup washer, and all O±rings lightly with hydraulic oil. Install new O±ring

(5) and uni±ring (4) to the piston (3). Install O±rings (7) and (8) and backup washer (9) to the head (10). Press dust seal (12) into head (10).

IMPORTANT: Do not clamp vise jaws against shaft

(6)surface. Protect shaft surface before mounting in the vise.

2.Mount shaft (6) securely in a vise. Adjust clevis (14) and jam nut (13) so the number of threads exposed be- tween the jam nut (13) and the smooth surface of the shaft is the same as noted during disassembly. The jam nut must be tight against rod clevis for this adjustment.

3.Coat shaft (6) lightly with hydraulic oil. Slide head (10) onto the shaft being careful not to damage O±ring

(7) and dust seal (12).

4.Install piston (3) onto the shaft being careful not to damage O±ring (5). Install locknut (2) onto the shaft and tighten.

5.Remove shaft (6) from the vise.

IMPORTANT: Prevent damage when clamping the barrel (1) into a vise; clamp on the pivot end only. Do not close vise enough to distort barrel.

6.Mount barrel (1) in a vise so that the shaft end tilts up slightly.

7.Coat all internal lift cylinder parts with a light coat of hydraulic oil. Slide piston (3), shaft (6), and head (10) as- sembly into barrel (1) being careful not to damage the seals.

8.Secure head (3) in barrel (11) by installing retaining ring (1) into barrel groove.

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.
