Residential ZTrak™ Mowers
24-hp (17.9-kW) engine
Overhead valve engine Key engine features include:
Air filter cover
Cover removed to show air filter First-stage foam filter stops large dirt particles before they make contact with the filter.
The air filter is easily removed for cleaning or replacement.
Engine cooling-air screen
Engine oil fill, filter, and drain Air screen cover provides protection for the rotating air screen. Rotating screen filters out debris and reduces the size of material that gets through so it will pass harmlessly past the engine fins.
Full-pressure lubrication system provides plenty of oil to the engines moving parts to ensure reliable operation and long life:
John Deere recommends the use of fuel stabilizer in gasoline. See Fuel-Protect for gasoline engines (8 oz [237 mL]) for more information.

MulchControl with baffle closed
MulchControl handle The MulchControl attachment makes mulching more practical for many mowing situations because it not only does an excellent job of mulching but it also allows the mower to be easily converted for times when it is more desirable to side discharge or collect the lawn material. Advantages of mulching grass clippings include:
MulchControl is an innovative, simple design that is easy to use and maintain:
MulchControl is well-suited to the following mowing situations:
MulchControl puts the operator in control of the clippings. Now the operator can have all the benefits of mulching with the ability to easily change to side-discharge or bagging when needed.
MulchControl limitations
While in the side-discharge mode, MulchControl will still mulch about one third of the material. Therefore, the side-discharge mode is essentially a partial-mulch mode. This can be an advantage when side discharging or bagging, as it helps to reduce the amount of material being discharged. Other times this could work as a disadvantage:
MulchControl compatibility
MulchControl is a field-installed attachment. Mulching blades are included:
