This statement is still true today.

these limitations will lead to better performance and life from the hybrid electrical components (e.g., e-reel motors and generator).

Before Operation: – Check the air cleaner before starting the scalping process. – Maintain reel and bedknife sharpness. – Maintain proper reel to bedkife clearance. Toro recommends light contact. – Follow and maintain the 1/3rd rule (i.e., only cut 1/3rd of the grass height). – Reduce the reel speed. The reel motors, as with any electric motor, trade speed for torque: at a higher speed, less torque is acquired; at a lower speed, more torque is acquired.

– When possible, reduce long passes, especially when scalping up hills. • Verticutting: Verticutting requires the most power from the machine, as this is a ground-engaging process. Depth of the verticutters, reel speed, and traction speed are the variables that must be adjusted correctly for the Reelmaster 5010-H to operate efficiently. Follow these best practices for verticutting: Before Operation: – Reduce the reel speed.
PAGE 5
During Operation: – Use the InfoCenter to monitor both engine coolant and generator temperatures (Figure 4). – Frequently check the rear radiator screen and the air cleaner and generator air inlet screen (Figure 3) above the radiator for chaff build up. – When possible, reduce long passes, especially when verticutting up hills. • Machine Maintenance: Scalping and verticutting are dirty jobs that create a lot of chaff, dust, and debris.
