GROUNDSMASTER® 5900/5910 SERIES
MODEL GROUNDSMASTER 5900 GROUNDSMASTER 5910
ENGINE
Yanmar 3.3L, EPA Tier 4 Final and EU Stage V emissions compliant, turbocharged diesel with direct injection and electronic high-pressure common rail. 72 hp (53.7 kW) @ 2500 rpm,
Torque: 206 lbf•ft (279 N•m) @ 1625 rpm Displacement: 202 cu. in. (3.3 L).
COOLING SYSTEM
24V dual electric fan banks for separate engine radiator and hydraulic oil cooling; fan banks are variable speed, with auto-reverse feature (SmartCool®, based on coolant and oil temps),
radiator is cross flow, 3 rows, 9 fins per in. (FPI). Hydraulic oil cooler is crossflow, 6 FPI. Cooling fan banks tilt away for fast, easy cleaning.
CAPACITIES Fuel: 35 gal (132 L) Hydraulic: 19 gal (71.9 L) Engine Oil w/filter: 11 qt (10.4 L) Coolant: 13.5 qt (12.7 L) (Model 31698), 18 qt (17 L) (Model 31699)
HYDRAULIC SYSTEM Capacity: 19 gal (71.9 L) reservoir, Remote spin-on charge filter, Oil: Toro premium all-season extended life PX Hydraulic Fluid.
POWERTRAIN
Full time automatic forward and reverse 4WD in low (mow) range. Front wheel drive in transport. Parallel hydrostatic, closed loop with cross wheel traction (CrossTrax™) design;
traction drive pump: variable displacement piston, servo control. Front drive: 2-speed, fixed displacement high torque, low speed radial piston motors. Rear drive: single speed, fixed
displacement, high torque, low speed radial piston motors. Smart Power® feature controls traction speed to maintain optimal cutting blade speed.
PRODUCTIVITY
Infinitely variable speed. Forward speeds: mow: 0-10.8 mph (17.4 km/h) Transport: 0-20 mph (0-32.2 km/h). Reverse speeds: mow 0-5.7 mph (0-9.2 km/h), transport: 0-10.5 mph (0-16.9
km/h) transport. Speed control: Electronic, limits max speed. Maximum productivity: 20.8 acres/hr. (8.4 ha/hr).
