The ZTrak™ M and R Series Mowers are equipped with either a side-discharge or Mulch On Demand™ 7-Iron PRO deck.

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:

  • Deck is stamped from 7-gauge, 0.179-in. (4.6-mm) steel to minimize the number of welds and provide a smooth underside with fewer sharp corners for reduced material buildup.
  • Significantly fewer welds on the deck shell to wear or break - it is stamped from a single sheet of steel rather than multiple fabrications. An anti-skid step on the deck provides easy machine mounting.
  • Higher blade tip speed than many competitors - 18,500 fpm (5,639 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 wider and higher discharge opening provides even clipping dispersal for an excellent finished appearance in all conditions.

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.

The ZTrak™ Z900E, M, and R Series Mowers are equipped with a standard two-post folding ROPS and seat belt. The folding ROPS enhances operator safety and provides ample clearance when storing the mower in garages or sheds:

  • ISO21299 certification
  • Foldable

The ROPS system can be repositioned without the use of tools. Under normal operation, the ROPS should be in the up position. If operating in low clearance areas, they can be folded and secured out of the way. The ROPS can also be pinned halfway down to accommodate machines equipped with a material collection system.

Spindle assembly Spindle assembly

On every John Deere ZTrak™ mower deck, there are three 1-in. (2.5-cm) spindles that are cold-forged and heat-treated for strength without bulk. The spindles are supported by precision ball bearings, providing great performance and reliability.
 
The spindle housing is made of aircraft-grade, ribbed cast aluminum on 48-in., 54-in., and 60-in. (122-cm, 137-cm, and 152-cm) decks, including Mulch On Demand™ configurations. This unique casting design embosses reinforcing gussets in the housing, which adds both strength and cooling surface area that stands up to commercial applications.
 
These spindles can be greased from the top and require no disassembly to reach. Grease channels provide lubrication to both bearings.

Propane conversion kit on a ZTrak Mower Propane conversion kit on a ZTrak Mower

John Deere provides application-specific Environmental Protection Agency (EPA) approved field-installed propane conversion kits for specific John Deere Commercial Walk-Behind Mowers, QuikTrak Mowers, and ZTrak Mowers. The conversion kits include all components required to convert the engines to operate on propane fuel. Single-tank or dual-tank brackets (depending on the vehicle) are provided for securely holding the propane tank(s) to the vehicle.

Propane tanks are not included.

An optional altitude kit is required when operating at altitudes above 2000 ft (610 m). The operator’s manual with the propane conversion kit provides further details. Parts must be ordered separately through John Deere Parts.

Propane facts:

  • Propane is flammable and commonly used as a fuel.
  • The molecular formula of propane is C3H8, and it is in the family of liquefied petroleum gases (LP gases). The other LP gases include butane, propylene, butadiene, butylene, isobutylene, and mixtures thereof.
  • Propane is commonly available and has proven to be a dependable, safe, economical, and clean-burning fuel. It can be used as household fuel, industrial fuel, and fuel for internal combustion engines. Propane has been used as a fuel since 1910.
  • At atmospheric pressure, propane boils at -44°F (-42.2°C), meaning it typically exists as a vapor. However, when contained under pressure, such as in a propane cylinder, it can exist as a liquid.
  • Propane is naturally odorless, but includes an additive odorant, usually mercaptan, which gives it a distinct odor.
  • Vapor propane is heavier than air, meaning it will settle in low areas such as along the ground or in drains.

 Advantages of John Deere propane conversion kits include:

  • Reduced fuel costs, up to 30 percent depending on fuel prices
  • Lower emissions
  • Reduced fuel-system maintenance
  • Maintains John Deere warranty
  • EPA and CARB certified
  • May qualify for national and state rebate and incentive programs. Please visit www.propane.com/commercial-landscape/programs-and-incentives/ for further information.

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.

Great power and speed

4/5

I had a 737 then the 920M both with 54” decks. The 920 seems to have more power and a better ride. No push rod issues. The flashing light trouble codes make the machine less user serviceable. The fuel fill is too small for fueling using 5 gallon cans and a funnel. If you fill too fast it blows gas everywhere.

Pros

  • adjustable seat
  • good feel on the sticks
  • fast
  • very heavy duty deck.
  • fuel gauge
  • tank holds 11 gallons.

Cons

  • fuel fill is way too small.
  • front wheels are not centered with the deck
  • fuel blows out if filled too fast

Nice mower!

5/5

First, I have been buying John Deere mowers for over 20 years. I recently caught new lawn mower fever so I traded in a 2013 model Z915b with 54” deck an 350 hrs for a new Z920m 54”deck with the suspension seat upgrade. Nothing wrong with the trade in mower. I am a residential mower; not commercial. Mower was on sale so I traded in. I LOVE my new Z920m! Mowed with it twice so far. Excellent cut, power an comfort with the Z920m. Only has about 3hrs still has the break in oil but I can tell this mower will last me 20yrs. Front caster wheels started squeaking but really not an issue. I ordered the built in jack so I can lift it to work/clean underneath the deck. Removing the front wheels and applying grease not an issue. The jack works perfectly. Was able to lift the front an remove the front wheels an apply grease to the axle bolts. Cured the squeaks. Been running it at different engine throttle speed to make sure everything will be okay with the Kawasaki engine. YuP, this Texan recommends this mower!

Pros

  • powerful kawas standa engine
  • excellent manicu look
  • very comfo
  • airless front tires

Cons

  • squeak front wheels
  • none

BEST ZERO TURN I'VE EVER OWNED!!

5/5

WOW. That's my first thoughts on this mower. What in incredible machine. I have used essentially every other brand, as I've been mowing for years, but always stayed away from John Deere's because of over priced reputation.....but now I get it. You get what you pay for. And this is the best. I'll never NOT use John Deere products again. I LOVE my Z920M.

Pros

  • mows fast
  • super powerful
  • easy to change oil
  • strong deck

Cons
