The John Deere ZTrak PRO Z925 with Electronic Fuel Injection (EFI) offers a closed-loop fuel injection system that constantly monitors engine performance. Fuel injectors respond to the load on the engine with the right amount of fuel, delivering maximum fuel efficiency for the conditions.
“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 27-hp engine includes a 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 or 60-inch, 7-IronPRO mowing deck. 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.
For durability, the Z925 EFI, and the entire Z900 Series, provides a C-Chanel frame, and cast iron rear bumpers and front forks. Additional confidence is provided by internal wet disk brakes for superior braking.
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.
