7-Iron PRO mower decks have demonstrated quality, performance, and durability. They deliver a high-quality cut in diverse conditions.
Key features of the 7-Iron PRO mower deck:
On every commercial mower deck there are three 25-mm (1-in.) spindles that are cold-forged and heat-treated for strength. Spindles are supported by precision ball bearings that provide great performance and reliability.

The deluxe comfort seat with armrests and isolation is available on the E, M, and R Series:
Two-lever hydrostatic control provides the following:
The Brake & Go starting system is a John Deere exclusive. This feature makes the starting process on all ZTrak™ mowers easier, while also making it possible to remove two interlock switches from the machine.
The Brake & Go starting procedure helps a novice operator look and feel like a professional. To start the machine, the parking brake must be engaged. It does not matter whether the power take-off (PTO) switch is on or off, nor does it matter if the control levers are pulled in or in the out position.
As long as the parking brake is engaged, the machine will start. When the parking brake is applied, the control levers cannot be moved to the forward or reverse positions.
The motion control levers have two height positions and can also be adjusted forward or rearward within the slotted holes. The levers should be adjusted so the operator can achieve a full range of control operation comfortably.
The easy-to-turn (from-the-seat) tracking adjustment allows operators to keep their mowers straight and produce professional striping results.
Several storage areas are provided on the ZTrak machines. A convenient cup holder is also available.
The controls are grouped together on the right console, providing one central location for key switch, throttle, PTO engagement, height-of-cut, diagnostics, and hour meter.
An easy-to-use cutting-height lift system allows the operator to adjust the mower deck height with no tools and minimal effort. The easy-to-grip knob allows operators to dial in the desired height of cut (HOC).
Cutting height can be adjusted from approximately 1 in. to 5.5 in. (2.5 cm to 14 cm). Each increment on the knob adjusts the HOC approximately 0.25 in. (0.64 cm). The deck can also be raised and locked in a transport position to provide maximum ground clearance when moving the machine from one area to another.
The transport lock function allows the deck to be returned to the previous HOC after being in the transport position:
This design increases productivity by allowing operators to change the cutting height without having to leave the seat.
An exclusive 2-year, unlimited hour/3-year, 1200-hour (whichever comes first) bumper-to-bumper warranty is standard for all John Deere E and M Series Mowers. The warranty is best in its class and places John Deere at the forefront of commercial mowing. It is also hassle free, with one company handling all of the paperwork.
NOTE: 36 months or 1200 hours, whichever comes first. For the first 24 months, there is no hour limitation.
An exclusive 2-year, unlimited hour/3-year, 1500-hour (whichever comes first) bumper-to-bumper warranty is standard on all John Deere R Series mowers. The warranty is best in the industry and puts John Deere at the forefront of commercial mowing. It is also hassle free, with one company handling all of the paperwork.
NOTE: 36 months or 1500 hours, whichever comes first. For the first 24 months, there is no hour limitation.
Mowers decks are evaluated by the manufacturer (John Deere Turf Care) and conform to American National Standards Institute (ANSI) B71.4 2004 safety certification specifications for commercial turf care equipment.
The durability features of the frame are as follows:
A steel rear bumper provides protection for the machine. The bumper is made of two pieces, making it easy to remove and install when using a material collection system (MCS).
A rear hitch can be added to the steel bumper for towing purposes. ZTrak E, M, and R Series Mowers can tow up to 400 lb (181.4 kg).
