Easy to use control panel

Easy to use control panel

The John Deere ZTrak instrument panel is the easiest to use on the market. Think 'yellow to go, orange to mow’ and you’ll be alright. The on-the-deck adjustment twist knob is one of a kind. No worries of having to move a pin or break your back pulling a lever. Just select your cut height with the black knob, press in the easy use foot lever and unlock the deck with the yellow knob.

Add tweels for a better ride

Add tweels for a better ride

We all know the obvious of airless tires... no flats. What most don’t know is that they give you a better ride on rougher terrain, have a longer life and have more traction on hillsides than pneumatic tires. The same quality and engineering that you would expect from companies like John Deere and Michelin.

60" 7-Iron stamped deck

60" 7-Iron stamped deck

You may hear other commercial mower manufacturers talk about their 7-Iron decks, but the difference is in how they are made. Most are manufactured and have welded corners where clippings build up and reduce vacuum lift, resulting in lower cut quality. John Deere’s stamped deck provides a smooth surface, preventing grass clippings getting caught up in corners.

Easy to access maintenance points

Easy to access maintenance points

From the onboard maintenance chart to the flip up foot panel and seat, the z915E is an easy machine to work on. The Kohler engine doesn’t have the regular drain plug for oil; instead, it has a drain hose which keeps oil changes clean and easy. Come check it out at one our locations.

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.

Adjustable levers

Easy-to-operate height-of-cut adjustment enables on-the-go changes
Mower deck height adjustment knobMower deck height adjustment knob

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:

  • Use the foot-lift pedal to lift the deck and engage the transport lock.
  • Rotate the knob to adjust from 1 in. to 5.5 in. (2.5 cm to 14 cm) in 0.25-in. (0.64 cm) increments.

This design increases productivity by allowing operators to change the cutting height without having to leave the seat.

    • This design minimizes the number of welds on the deck shell itself.
  • There is an anti-skid pad on the top corner of the trim side of the deck.
  • High blade tip speed - 18,500 fpm (5,638.8 m/min) for more blade cuts per inch mowed.
  • A deep-deck design of 5.5 in. (14 cm) delivers excellent airflow so material can be processed quickly and efficiently.
  • The wide and high discharge opening provides even clipping dispersal for an excellent finished appearance in all conditions.
Mower leading-edge reinforcement Mower leading-edge reinforcement
Double captured anti-scalp wheelDouble captured anti-scalp wheel
  • Deck has rectangular leading deck edge reinforcement, and the rounded corners of the stamped deck help distribute impact stress to reduce the potential of damage when the mower contacts trees, rocks, curbs, and other fixed obstacles.
  • Dual-captured anti-scalp wheels on the front of the deck provide flotation over even the toughest terrain. 
  • Three 1-in. (2.54-cm) cold-forged spindles are heat-treated for strength without bulk and are supported by ball bearings, providing reliability and performance; spindle housings are ribbed cast aluminum, providing both excellent strength and heat dissipation.
  • The front edge is raised above the blade plane to allow even cutting of tall grass and is reinforced with a square bar for durability. The front baffle has been designed to better manage airflow and control clippings.
  • Grease fittings on each of the three spindles are accessible from the top.
  • Blade overlap is 1.6 in. (40.6 mm) to reduce striping between blades.
  • Quick-change cutting-height adjustment is available.
