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
- •Reduced maintenance costs over the life of the machine
Heavy-Duty Commercial Decks
ZD decks are the heaviest and most durable in Kubota's mower lineup. Fabricated from thick-gauge steel with reinforced edges and commercial spindle assemblies, these decks are designed for daily use on parks, campuses, cemeteries, and other institutional properties.
- •48-inch (ZD1011) to 72-inch (ZD1511) deck options
- •Fabricated heavy-gauge steel with reinforced leading edges
- •Commercial greaseable spindle assemblies
- •Side discharge, mulch, and rear discharge configurations available
Hydrostatic 4WD Option & Premium Comfort
Select ZD models offer 4-wheel drive for superior traction on slopes and wet turf — a feature nearly unique among zero-turn mowers. Combined with a deluxe suspension seat, spacious operator platform, and Kubota's legendary diesel reliability, the ZD is built for decades of commercial service.
- •4WD option available for unmatched zero-turn traction
- •Deluxe suspension seat for all-day comfort
- •Wide operator platform with ample legroom
- •ROPS standard with folding option for low-clearance areas
