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

Mower deck height adjustment knob Mower 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.

  • Three 1-in. (2.5-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 iron providing both excellent strength and heat dissipation.
  • The trim edge of the deck is equipped with a bumper that provides great abrasion resistance to protect the machine and the property.
  • 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 redesigned to better manage airflow and control clippings.
  • Three spindle grease fittings are accessible from the top.
  • Blade overlap is 1.6 in. (40.6 mm), nearly 0.79 in. (20 mm) greater than previous decks, to reduce striping between blades.
  • Quick-change, cutting-height adjustment.

Mulch Kits
Mulch kitMulch kit
Mulch kit shown on Estate ZTrak™ mower deckMulch kit shown on Estate ZTrak™ mower deck

The mulching attachment allows converting the mowers so they can be used to perform the mulching function (grass or leaves) of this system.

The attachment consists of special mulching blades, mulch baffles to direct the clippings into the blade for recutting, and a discharge closure and hardware. The adjustable baffle can be moved to one of five positions to match conditions using the convenient wing nuts.

 

Operating tips when mulching:
  • Mow when the grass is dry.
  • Observe the one-third rule.
    • No more than one-third of the grass blade should be cut off at one time. This allows more efficient mulching and will promote the continued good health of the grass. If the desired cut height cannot be achieved by cutting off one-third, or there is clumping of the clippings, it may be required to cut higher; wait a day, then lower the mower and make a second pass.
  • Mow at proper intervals - approximately every four days to five days.
  • Always mow with sharp blades.
