Servicing Main Valve

WARNING

IF THE VALVE SNAP RING IS DIFFICULT TO REMOVE, RESIDUAL WATER PRESSURE MAY BE REMAINING IN THE SYSTEM. TO PREVENT POSSIBLE SERIOUS INJURY DUE TO VALVE BEING EJECTED UPWARD UNDER PRESSURE, CONFIRM THE FOLLOWING CONDITIONS EXIST PRIOR TO REMOVING THE SNAP RING AND VALVE:

A.WATER SUPPLY TO SPRINKLER IS SHUT OFF AT SOURCE.

B.All PRESSURE IS BLED FROM SYSTEM, INCLUDING CONTROL TUBES.

C.AC POWER IS DISCONNECTED AT SOURCE.

1.See WARNING above. To remove valve assembly, squeeze snap ring ears together with snap ring pliers (P/N 995-100) and remove snap ring from sprinkler body. See Figure 4.

2.Use valve removal tool P/N 995-08 for 830S or 995-09 for 850S to remove valve assembly from base of sprinkler body. Valve removal tool is inserted into sprinkler body and pushed through valve ribs. A slight twist will catch tool under ribs enabling valve removal by pulling straight up and out. See Figure 5.

Note: If valve removal tool is not available, use snap ring pliers to grasp rib of valve cylinder assembly and pull up and out of sprinkler body.

3.Reinstall valve assembly using valve insertion tool P/N 995-76 for 830S or 995-101 for 850S as follows:

•Load snap ring on insertion tool carrier with stepped side against carrier as shown in Figure 6. While holding snap ring in compressed position, slide retainer clip in to hold snap ring ears

•Load valve assembly on carrier as shown.

Figure 4

Figure 5

•Locate position of communication tube in bottom of sprinkler body and orient insertion tool accordingly.

•Insert tool straight down into sprinkler body aligning bosses on t-handle with holes on sprinkler body flange. When valve assembly clears vertical side wall ribs inside body, pull up on snap ring release mechanism (850S models only) and press valve assembly into position. Snap ring will lock into groove when properly installed. Remove insertion tool and check snap ring to confirm that it is fully seated in groove.

830S, 850S specifications

The Toro 850S and 830S are cutting-edge ride-on mowers designed for commercial landscaping professionals who demand durability, efficiency, and optimal performance. Both models boast an array of advanced features and technologies that provide unparalleled mowing capabilities while ensuring ease of operation and maintenance.

The Toro 850S is known for its robust engine performance, powered by a high-torque, gasoline engine designed to deliver outstanding cutting power. Its 60-inch or 72-inch cutting deck options allow for a broad mowing path, enhancing productivity by covering large areas quickly. Enhanced with Toro’s patented Smart Speed Technology, the operator can easily adjust the speed without compromising cutting performance, allowing for precise control when navigating tight spaces or around obstacles.

Similarly, the Toro 830S offers impressive performance with its own high-powered engine while providing a slightly more compact design. The 830S features a 52-inch cutting deck, which is excellent for smaller properties or areas with constrained access. Its agility and responsiveness make it a favorite among landscapers who need to manage intricate landscapes without sacrificing speed or cutting quality.

Both models integrate Toro’s patented Zero Turn technology, enabling the mowers to pivot within their own footprint, significantly reducing the time spent maneuvering around obstacles. This makes them particularly effective in complex environments, where traditional mowers may struggle.

User ergonomics are a top priority, with both mowers featuring comfortable seating and intuitive control layouts. This attention to operator comfort minimizes fatigue during long hours of operation, allowing landscapers to maximize productivity without compromising personal well-being.

Fuel efficiency is another area where the Toro 850S and 830S shine. Their engines are engineered for reduced emissions and optimized fuel consumption, making them environmentally friendly while also cutting operation costs over time.

Maintenance is simplified through a modular design that allows for easy access to vital components. This means that regular upkeep can be done quickly, ensuring that both the 850S and 830S remain in peak operating condition with minimal downtime.

In summary, the Toro 850S and 830S mowers are exceptional choices for professionals needing reliable, powerful, and efficient tools for their landscaping needs. Their combination of innovative technologies, operator-friendly features, and robust construction ensures that they stand out in the competitive market of commercial ride-on mowers.
