The instrument display has the look and feel of a modern automobile. A power-up sequence cycles lights and gauges to indicate they are working:

Display features dark-cockpit design to minimize operator distractions.
Display is back lit for night visibility.
- Night visibility is especially useful with snow blower use.
Hour meter makes it easy to tell when oil changes and other maintenance should be performed.
Electronic fuel gauge provides real-time fuel level information.
A tachometer graphically displays engine speed.
- Target-zone graphics inform the operator of the engine speed range to use for best cut quality.
An indicator tells the operator when the PTO is operating.
Bright caution and stop lights capture the operator's attention when important information is on the instrument cluster.
- Damage can be prevented and repair costs reduced by addressing problems early.
Operators are advised of what the problem is if they attempt to operate the mower with unsatisfied PTO, seat, or park brake interlocks.
- The indicators are also useful to identify the reasons the PTO or engine may have shut off when an interlock is unsatisfied.
Operators are advised if battery voltage is low, normal, or excessive.
The service indicator light illuminates to indicate a diagnostic error code is stored.
- On-board diagnostics provides trouble codes for use by trained technicians.
  - For example, a technician will be able to test switch functionality and circuit continuity without tools.

Twin Touch™ foot control is easy to use and has cruise control

Twin Touch foot control

Cruise control

Twin Touch foot pedals control the speed and direction of travel:

Automotive-type accelerator control for easy operation
Twin Touch design that allows operator to change direction without lifting foot off platform
Large pedal surface for increased operator comfort

When the master brake pedal is depressed, the PTO and cruise control disengage.

Cruise control is standard equipment:

To engage, push in on the cruise lever and hold until the foot is removed from the forward pedal.
For emergency stop, the cruise control can be released by pushing on the master brake pedal or pushing down on the forward pedal.

Differential lock

Differential lock control

A foot-operated differential lock supplies positive power to both rear drive wheels for increased traction:

Differential lock button is conveniently located on the left footrest for easy engagement.

Two-function hydraulics give effortless control of equipment

Dual hydraulic control levers

A two-function hydraulic control system is standard equipment.

The hydraulic system allows effortless equipment control:

Raising and lowering
Angling and spout rotation
Control levers

Levers are positioned on the steering pedestal for quick, easy, and precise fingertip control of equipment.
Lower lever has a float position, allowing front-mounted equipment such as a blade, snow blower, or rotary broom to follow the contour of the ground.

Hydraulic power steering gives effortless control

Power steering control valve

Power steering is standard equipment. It provides effortless, automotive-like control:

Reduced operator fatigue
Better maneuverability
Increased productivity

Parking brake control

Controls shaped and located for easy use

Controls shaped and located for easy use

Park brake control and brake pedal

The parking brake control is conveniently located below the key switch on the steering pedestal:

Holds the brake pedal securely in the locked position

Depressing the brake pedal disengages the PTO and cruise control:

Allows the engine to be started
Applies wet-disk brakes (internal in transmission) for use as a parking brake

Mower deck height-of-cut control

Mower deck height-of-cut control

Exact Adjust ports

The depth stop allows setting the mower height from the operator's seat:

Locks the mower in fully raised position so 3-point hitch equipment can be raised or lowered independently of the mower
Returns mower deck to the same preset height each time it is lowered
Provides a mower cut-height range from 1 in. to 5.25 in. (2.5 cm to 13.3 cm)
Informs the operator of the approximate mower cut-height through an indicator

Exact Adjust ports on either side of the fender deck allow access to the rear mower deck height adjusting links:

Allow mower deck to be easily leveled side-to-side
Leveling can be done from above the fender deck by using the Exact Adjust tool

Exact Adjust

Exact Adjust tool and mower leveling gauge

Exact Adjust tool and mower leveling gauge

Exact Adjust tool and mower deck leveling gauge are stored in the toolbox to provide a convenient means of checking and adjusting the deck level:

Used in conjunction with Exact Adjust ports for easy and accurate leveling of the mower deck for optimum mowing performance

Deck-leveling gauge placed under deck

Using included ball-hex tool to level mower deck

Using included ball-hex tool to level mower deck

Consult the operator's manual for the correct adjusting procedure. Basic adjusting steps to properly level the mower deck include:

Park the tractor on a level surface.
Inflate tires to the correct pressure.
Consult the label for the cutting-height knob that is located on the console of the machine. This label shows deck-leveling position and location of deck-leveling adjustment points.
Set mower cutting-height knob to the correct deck-leveling position.
Adjust mower wheels as necessary so they do not contact the ground surface.
Remove the onboard deck-leveling gauge and Exact Adjust tool that are located in the tractor toolbox.
Using the Exact Adjust ports and tool, adjust mower deck side-to-side level so the deck-leveling gauge just slips under the left and right lower deck rim. The location of adjustment points will vary slightly between decks.
- Left- and right-rear adjustment points are under the deck rim near the rear mower wheels.
Adjust mower deck front-to-back level, if necessary.
- Loosen rear nuts equally on each side of front lift rod.
- Turn front nut equally on each side clockwise to raise front of mower or counterclockwise to lower it until gauge just slips under the front adjustment point.
  - Front adjustment point varies by mower deck
- Tighten rear nuts after adjustment is complete.
Return the gauge and tool to their storage position in the toolbox.

NOTE: The adjusting tool supplied with the tractor is an 8-mm ball-hex key. The rounded end allows for some misalignment with the bolt as the deck is adjusted.

Hydraulic outlets

Four hydraulic couplers with color-coded covers are available for quick, easy connections.

Power take-off (PTO)/RIO switch (yellow switch)

Power take-off (PTO)/RIO switch (yellow switch)

Left-hand RIO switch (yellow button)

CAUTION: Children or bystanders may be injured by rotating blades. Before traveling forward or rearward:

Carefully check the area around the machine.
Disengage the mower before backing up.

NOTE: Backing up while the mower is engaged is strongly discouraged. RIO should be used only when operating another attachment or when the operator deems it necessary to reposition the machine with the mower engaged.

Stop forward travel.
Look behind the machine to be sure there are no bystanders.
Push and hold in the RIO switch while depressing the reverse pedal slightly
NOTE: If the mower or other attachment stops while repositioning the machine, return the attachment engagement switch to the off position. Start the engine and engage mower or other attachment. Begin again with step 2.
Release the RIO switch and reposition the machine as the machine begins to move rearward.
Resume forward travel. The mower or other attachment should continue operating.
Repeat procedure to position the machine again.

NOTE: For tractors equipped with an optional front PTO kit installed, the front implements will rotate while backing up without engaging RIO.

Interlock switches

The hydrostatic transmission foot pedals must be in neutral, with brake depressed, PTO disengaged, and the ignition key used, before the tractor will start.

Once the tractor is running, the engine automatically shuts off if the operator leaves the seat with the PTO engaged, brake pedal unlocked, or hydrostatic foot controls out of the neutral position.
