The Z925 EFi features a closed loop fuel injection system that constantly monitors engine performance, with the injectors responding to changes in engine load to deliver the maximum fuel efficiency for the conditions. The fuel savings delivered by this new model will no doubt be welcomed by landscaping contractors, commercial gardeners, groundskeepers and other high volume users.
"With a closed loop system, the engine actually checks for unused oxygen in the exhaust multiple times per second," said Jamie Palmer, John Deere product manager. "This means the engine can fine-tune the amount of fuel injected into the engine, resulting in up to 25 percent fuel savings in real-world use."
The 20.1 kW (27-hp)* engine includes an exclusive Tuff Torq® integrated transmission. The transmission, which is standard across the ZTrak PRO 900 Series, features 13cc piston style pumps and 13cc wheel motors for increased efficiency. Another series exclusive, is the cross-porting system that routes the coolest hydraulic fluid to the hydraulic pump doing the most work.
The Z925 EFI offers a 54-inch (137.2 cm) or 60-inch (152.4cm), '7-Iron' PRO mowing deck, with zero-turn manoeuvrability. The decks are stamped from 7-gauge steel for maximum durability and enhanced mowing performance. The 54-inch deck also includes exclusive Mulch-On-Demand technology that allows the operator to switch between mulching and side discharging without ever leaving the seat.
Two other convenient features include the Height-of-Cut Adjustment system, and the Brake & Go™ starting system. The Height-of-Cut Adjustment system allows the operator to adjust the mower deck height without ever leaving the operator's seat. With the Brake & Go starting system, the operator only needs to set the parking brake and turn the key to start the mower. Along with the rest of the Z900 series, the Z925 EFI features a C-Chanel frame, and cast iron rear bumpers and front forks, with internal wet disc brakes for superior braking.
"The John Deere Z900 Series provides the power and performance that landscape contractors expect," said Palmer. "And now with the John Deere Z925 EFI, they can get the fuel savings they need."
