STEP 13: HYDRAULIC SYSTEM, PURGING

When initially putting hydraulic system into service, one or both of the wheel drives may not pull properly. This is likely to be caused by air entrapped in the system. If you experience a pulling issue during initial setup or after com- pleting repairs, perform the following procedure to purge the air from one or both of the hydraulic drive systems.

IMPORTANT: WHEN REPLACING THE HYDRAULIC FLUID FILTER, PRE-FILL WITH OIL (SAE 20W50 API SL) BEFORE INSTALLING. PRE-FILLING THE FILTER WITH OIL WILL REDUCE OR POSSIBLY ELIMINATE THE NEED TO PURGE THE SYSTEM OF ENTRAPPED AIR.

A. Locate hydraulic reservoir underneath operator’s seat. After thoroughly cleaning the area around the top of each reservoir, remove filler cap. Bring fluid to proper level (1 ½” below the top of the filler neck). With engine off, add SAE 20W50 automotive oil. See Figure 7.

B. Open pressure relief valve on hydraulic pump, turn- ing counter clockwise 2 full turns. See Figure 8.

C. Carefully raise the rear of the machine so the wheels are off of the ground. Securely block the machine to prevent it from falling.

D. While seated in the operator’s position, start the engine. Place engine speed control in FAST position. E. Release parking brake and move motion control levers out of the neutral lock position.

F.Slowly move motion control levers to the full forward and then to the full reverse positions. Repeat this process 6 times.

G.Stop engine and wait for all rotation to stop before leaving the operator’s position.

H.Close pressure relief valve on hydraulic pump, turn- ing clockwise. Tighten snuggly.

I.With pressure relief valve closed, repeat Steps D thru G.

J.Remove blocks and lower rear of machine.

K.Check fluid level in reservoir. Add SAE 20W50 automotive oil as required to bring fluid level to 1 ½” from top of filler neck. Do Not over fill.

L.Install and tighten filler cap.

Zero Turning Z-Riding specifications

The Snapper Zero Turn Z-Rider series is a robust and innovative solution for landscapers and homeowners looking for an efficient way to maintain their lawns and gardens. This line of zero-turn mowers is designed to navigate tight spaces with exceptional agility, allowing users to tackle a variety of mowing tasks with ease.

At the heart of the Snapper Zero Turn Z-Rider is its unique zero-turn technology. Unlike traditional riding mowers, which require wide turning arcs, the Z-Rider can pivot 180 degrees in place. This capability drastically reduces mowing time, especially in complex landscaping where obstacles, trees, and flower beds are present. The dual-lever steering system further enhances maneuverability, allowing the operator to seamlessly control speed and direction with just a touch of their fingers.

One of the standout features of the Snapper Zero Turn Z-Rider is its powerful engine options. Equipped with durable Briggs & Stratton or Kohler engines, these mowers deliver the performance needed for heavy-duty cutting tasks. Users can choose from various engine sizes to match their specific mowing needs, ensuring optimal power and efficiency. Coupled with a high-performance cutting deck, typically available in sizes ranging from 48 to 60 inches, the Z-Rider delivers a clean and even cut every time.

Technology plays a critical role in the design of the Snapper Zero Turn Z-Rider. The mowers feature a robust hydrostatic transmission that provides smooth speed control. This advanced transmission system allows for rapid acceleration and deceleration, making it easier to navigate various terrains. Additionally, the Z-Rider boasts an ergonomic design with adjustable seats and controls to enhance operator comfort during extended mowing sessions.

Durability is another key characteristic of the Snapper Zero Turn Z-Rider. The chassis is constructed from heavy-duty steel, providing a sturdy platform that can withstand the rigors of regular use. Furthermore, the mower is equipped with reinforced cutting decks that are built to last, reducing the need for frequent replacement or repairs.

Safety features are designed with the operator in mind. These include anti-tip technology and automatic brake systems, ensuring that the mower remains stable and secure during operation. The easy-access maintenance points simplify routine checks and upkeep, making it user-friendly for both novice and experienced operators.

Overall, the Snapper Zero Turn Z-Rider series combines cutting-edge technology, powerful performance, and robust durability, making it an ideal choice for anyone looking to achieve a beautifully manicured lawn with minimal effort.
