ZD Series Diesel Zero-Turn
The ZD series is Kubota's premium diesel zero-turn line — the only zero-turns on the market powered by Kubota's own diesel engines with shaft-driven PTO. These are heavy-duty commercial machines designed for municipal, institutional, and large-property use where diesel fuel efficiency, torque, and extreme longevity are priorities.
Kubota Diesel Engine Power
While most zero-turns use gas engines, the ZD series runs Kubota's own 3-cylinder diesel engines — the same proven platforms used in Kubota tractors. Diesel delivers significantly more torque than gas at low RPM, which means the ZD powers through thick grass and tough conditions without bogging down.
- •Kubota 3-cylinder diesel: 19 HP (ZD1011) to 30.8 HP (ZD1511)
- •Diesel torque advantage — powers through heavy, wet grass without stalling
- •Fuel efficiency savings of 30-40% vs comparable gas engines
- •Kubota-built engine with worldwide parts support
Shaft-Driven Mower Deck (No Belts)
The ZD series drives its mower deck via a shaft-drive PTO system rather than belts. This eliminates belt slippage, stretching, and replacement — one of the most common maintenance headaches on commercial mowers. The result is consistent blade speed and reduced downtime.
- •Shaft-drive PTO eliminates mower deck belts entirely
- •Consistent blade speed regardless of load or conditions
- •No belt replacement, tension adjustments, or slippage
What Owners Say

- •Shaft-drive PTO and heavy-duty deck handle the most demanding commercial properties
