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:

• Replaceable oil filter keeps the oil cleaner for a longer engine life.
  • Extends the time between oil changes
• Full-pressure lubrication is more effective.
• No-tools oil drain is convenient to use.

John Deere recommends the use of fuel stabilizer in gasoline. See Fuel-Protect for gasoline engines (8 oz) for more information.

• Better traction

The operator platform is roomy and uncluttered for maximum comfort, and the controls are convenient to use:

• Easy to get on and off the mower
• Ample legroom for comfortable operation
• Adjustable motion-control levers for height and position, enabling the operator to stay comfortable while using them
• Color-coded and logically placed controls

60-in. (152-cm) HC Mower Deck

The 60-in. (152-cm) HC Mower Deck has a deep-deck design.

60-in. (152-cm) HC Mower Deck shown on a Z540R

Reinforced mower edge for durability

The 60-in. (152-cm) HC Deck is stamped from heavy, 9-gauge, 0.150-in. (3.8-mm) steel to minimize the number of welds and provide a smooth underside for reduced material buildup:

• Deep-deck design delivers excellent airflow, so material can be processed quickly and efficiently.
• Wider and higher discharge opening provides even clipping dispersal for an excellent finished appearance in all conditions.
• Durable plastic deflector spreads grass clippings evenly across the lawn, is hinged, and can be raised to minimize the storage space required.
• 1-in. (25.4-mm) cold-forged spindles are heat-treated for strength and are supported by ball bearings.
• Standard front roller and two double-captured anti-scalp wheels give a more even mowing job and reduce the chance of scalping.
• Front edge is raised above the blade plane to allow even cutting of tall grass.
• Blade overlap is greater than many conventional decks, for a clean cut.
• Mower can side-discharge or mulch.

• The special mulching blades that are included can also be used for side discharging, though overall performance may be slightly less than with the standard mower blades.
• Order: BM23978, 60 HC mulching attachment

Optional MulchControl™ attachment

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 the lawn material. Advantages of mulching grass clippings include:

• A beautiful looking lawn
• Grass clippings not blown onto the operator, driveways, or flower beds
• Less fertilizer use
• Elimination of the effort needed to dispose of clippings

MulchControl is an innovative, simple design that is easy to use and maintain:

• The MulchControl attachment includes baffles to control the flow of material under the deck.
• The left mower blade area is completely enclosed and optimized for mulching, thus will mulch even when the mower is in the side-discharge mode.
• Baffles around the center and right blades are optimized for mulching when the discharge baffle is closed.
• The MulchControl handle is located on top of the mower deck and used to open and close the discharge baffle.
• The operator is required to get off of the machine in order to engage or disengage mulch mode.
• Changing from mulching to side discharge or vice versa takes only a few seconds.

MulchControl is well-suited to the following mowing situations:

• Usually mulch, but side-discharge when grass gets too long
• Usually side discharge, but would like to be able to close the chute to control clippings
• Always mulch a main lawn, but often side discharge secondary lawns

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 the side-discharge mode 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, as it helps to reduce the amount of material being discharged. Other times this could work as a disadvantage:

• When cutting strong southern grasses, such as Zoysia and Bermuda
• When cutting in wet, high-growth conditions, such as those found in the Pacific Northwest United States
• When optimum lawn clean-up is desired

MulchControl compatibility

MulchControl is a field-installed attachment. Mulching blades are included:

• MulchControl is for 2015 and later EZtrak™ Z665 Mower (SN 170,001-) and ZTrak™ Z540R.
