CARE FOR HYDRAULIC SYSTEM

To keep the hydraulic system in working order, there are a few steps needed to take place. If synthetic oil were used we would suggest a full synthetic oil such as Mobil 1 15W50, Quaker State Full Synthetic 5W50, or a similar oil.

Oil viscosity is very important to transmission life. For optimum performance the oil viscosity should maintain a viscosity of 13 cSt [70 SUS].

The minimum oil viscosity to prevent component wear is 9 cSt [55 SUS]. These Viscosity requirements are for an oil temperature of 110 degrees Celsius [230 degrees Fahrenheit] Typically; standard SEA 20W-50 multi-viscosity motor oils will meet this requirement. If the operating temperature is elevated then synthetic oil with greater viscosity index, or more viscosity at elevated temperatures, may be needed to meet viscosity requirements.

System Start-up: (purging air from system). Factory Fills unit with SAE 20W-50 multiviscosity motor oil. This will need to be checked when setting up with instructions below.

At system start-up, several things need to be accomplished to ensure a properly running system.

1.Fill the BDU case and expansion level and ensure they do not empty during the following procedure.

2.Start engine and increase throttle to at least 2/3 speed.

3.Open bypass valve by depressing bypass plunger and holding.

4.Adjust control linkage such that transmission control is stroking full forward.

5.Move and hold control in forward for

3 seconds; repeat two additional times.

6.Close bypass valve be releasing bypass plunger.

7.With engine still at same speed, repeat step 5.

8.Move control to neutral.

9.Check engine speed. Adjust to recommended maximum engine speed.

10.Adjust neutral position.

11.Adjust forward control stop to recommended axle speed.

12.Adjust reverse control stop to recommended axle speed.

13.If axle speed is not achieved ensure linkage allows proper movement of transmission control.

14.If transmission control lever is rotating fully but recommended axle speed is not achieved, repeat start-up procedure.

15.Refill expansion tank oil to recommended level.

Classen TSS-20, TRS-20 manual Care for Hydraulic System

TRS-20, TSS-20 specifications

Classen TSS-20 and TRS-20 are two powerful tools designed for turf care and soil management, specifically targeting professional landscapers and dedicated gardening enthusiasts. Both models are equipped with a host of features, technologies, and characteristics that facilitate efficient turf maintenance and soil aeration.

The Classen TSS-20 is primarily recognized for its superior turf seeding capabilities. With a 20-inch seeding width, it allows for wider coverage and faster operation, making it ideal for larger areas. The TSS-20 features a precision seed delivery system that ensures even seed distribution and minimizes waste. This system is designed to accommodate a variety of seed types, including fescue, rye, and bluegrass, enabling users to customize their seeding approach based on their specific lawn care needs.

On the other hand, the TRS-20 is tailored for aerating soil and enhancing root systems. The TRS-20 utilizes a core aeration method, where it pulls out soil plugs, thereby reducing soil compaction and promoting better drainage. The unit is equipped with heavy-duty tines that penetrate deep into the soil, enabling it to reach areas otherwise inaccessible. This process significantly enhances turf health by allowing essential nutrients, water, and air to penetrate the root zone.

Both the TSS-20 and TRS-20 are powered by reliable, high-performance engines, ensuring robust operation even in demanding conditions. Their compact and lightweight design allows for easy maneuverability, while the collapsible handles provide convenient storage options when not in use.

In terms of maintenance, both models are designed for durability and longevity. They feature corrosion-resistant components and are easy to service, ensuring minimal downtime for users. The intuitive control interfaces make operation straightforward, allowing even novice users to achieve professional-quality results.

In conclusion, the Classen TSS-20 and TRS-20 represent cutting-edge solutions for turf care and soil management. Their unique features, innovative technologies, and user-centric designs make them invaluable assets for anyone looking to maintain a healthy and vibrant lawn. Whether for professional landscaping or personal gardening projects, these machines deliver consistent performance and results that exceed expectations.
