Diesel power and PRO decks — the fleet workhorse that outlasts the gas machines.

Diesel engines generally deliver better fuel economy and longer engine life under heavy daily use, which is why the ZD series is built for fleets, municipalities and estates racking up hundreds of hours a season. For lighter or occasional mowing, a gas machine like the Z700 or Z400 is usually the more economical choice.
Kubota's PRO decks are the heavier-built decks used on its commercial diesel zero-turns, intended to stand up to the wear of full-season fleet or municipal mowing better than the decks on residential machines. I'd confirm the exact construction details for the deck size you're considering before buying.
The ZD series ranges from 48 up to 72 inches, letting fleets and municipalities match deck width to the size of the properties or right-of-ways they're cutting.
Not usually. Estates with several acres of maintained lawn are exactly the kind of high-hour, multi-season use the ZD was built for. The diesel engine and PRO deck earn their keep once you're mowing several days a week rather than just weekends.
