Approximately 28 HP (based on model number ZD28-EC)
Torque Rating:
Specific torque figures would be detailed in the manual, contributing to its power for mowing tough grass.
Fuel System
Fuel Type:
Diesel
Injection System:
Indirect Injection or Direct Injection (Common for Kubota diesel engines of this era)
🔧 Transmission
Standard
Type:
Hydrostatic Transmission (HST) with Dual Range or similar zero-turn drive system
Optional
Variations:
Likely variations in specific transmission manufacturers or internal components depending on build date and sub-model.
Features
Drive System:
Independent wheel motors or integrated transaxles for zero-turn maneuverability.
📐 Dimensions
Exterior
Type:
Zero-Turn Radius (ZTR) Riding Mower
Weights
Operational Weight:
