Summary of 48"/52" GrandStand changes for 2010 ...
Engine: The 24 hp Kawasaki FS engine replaces the 23 hp Kawasaki FH engine.
Deck lift system: The deck lift assistance on the 2010 models is provided by a pair of extension springs (as opposed to the gas springs used on the 2009 models). Benefits include improved longevity and the ability to adjust the amount of lift assistance to accommodate different preferences or different applications. In addition, improvements were also made to the lift handle and associated parts.
Frame: Changes were made to the design of the frame primarily to accommodate the addition of the new 60" GrandStand model, and to ensure greater consistency in the manufacturing process.
Throttle control: The 2010 throttle control cable "pulls" the engine control plate to high idle (as opposed to the 2009 design where the cable "pushed" the control plate to high idle). This change was made to better handle variation in the resistance of the engine control plates.
Steering controls: A number of enhancements have been made to the Toro steering controls for 2010, including more robust spherical rod ends on the steering cables, oil impregnated bushings in pivot hubs, improved alignment and clearance between parts, and tighter tolerances (including the replacement of wire form connecting links with laser cut parts for greater consistency). Because the hydraulic pumps move relative to the control levers (in response to changes in the height of the cutting deck), the hydraulic pumps cannot be controlled with a solid link. We will continue to utilize push-pull cables (rather than a series of moving links) to activate the hydraulic pumps, because they significantly simplify adjustment of the controls and they ensure the machine can achieve maximum ground speed throughout the entire range of cutting heights. As an added benefit, GrandStand models will continue to feature the exclusive variable speed control (patent pending) that can be used to change the drive tire response by adjusting the sensitivity of the control levers.
Fuel tank: Fuel capacity of the 2010 models increases from 6.8 gallons to 7.8 gallons.
Operator pad: The material of the operator pad on the 2010 Toro GrandStand models changed from vinyl to a Cordura(R) fabric, which breathes better and is more durable in this application.
What didn't change for 2010: The 2010 models will continue to deliver the outstanding operator comfort, exceptional hillside performance, and incredible TURBO FORCE cut (particularly in dense and wet conditions) that made the Toro GrandStand the talk of the industry in 2009.
