John Deere Easy Change 30-second oil change system

John Deere Easy Change 30-second oil change system

The John Deere Easy Change 30-second oil change system makes changing the engine oil easy, quick, and clean. Changing the oil is as easy as removing the old oil-filled filter and twisting on a new oil-filled filter. Oil does not need to be drained from the engine. The removed filter contains the captured contaminants and a portion of the engine oil. Easy Change is standard equipment on the X166 and X166R.

Fuel tank has sight gauge to show fuel level from the operator's seat

Fuel tank sight gauge

The fuel tank sight gauge allows the operator to tell how much fuel is in the tank without leaving the seat:

• Fuel level is easy to check.
• Convenient location - sight gauge can be seen from the operator’s seat.
• Fuel tank capacity is 8 L (2.1 gal.).

John Deere Easy Change 30-second oil change system

The John Deere Easy Change 30-second oil change system makes changing the engine oil easy, quick, and clean. Changing the oil is as easy as twisting on a new oil-filled filter. Oil does not need to be drained from the engine.

The John Deere Easy Change filter is an additional engine oil reservoir. Changing the filter removes the captured contaminants and replaces about 0.8 qt (0.76 L) of the engine oil.

The functionality does not stop with ease of use. The Easy Change oil system has several meaningful benefits over the traditional oil filter system of the 100 Series:

• A synthetic filter material is used for more predictable filtering and longer life.
• Filtering capacity is greater than with a standard oil filter.
  • More filter surface area
  • More oil flow capacity
• The system has 40 percent more oil volume.
• The oil and engine run cooler.
• The oil filter valve closes whenever the engine stops, so filtered particles are captured and cannot drain back into the engine.
• The risk of spilling during oil service is greatly reduced.
• Waste oil (and new oil production) is reduced by over 1,000,000 lb (453,592.4 kg) per tractor production year.
• This system is not a compromise to just make oil changes easier—these engines pass the same expectations and rigorous testing as always.

Partly due to these improvements, it is not necessary to remove and dispose of all the oil in the engine during service.

Everyone who uses the John Deere Easy Change system saves time and avoids the mess of a traditional oil change. In the past, many 100 Series Lawn Tractor owners rarely or never got around to changing their engine oil. With John Deere Easy Change, even owners who previously would not consider changing the oil themselves can easily do it now. The Easy Change 30-second oil change system is a no-mess, no-fuss solution the competition cannot match.

Installation instructions are in the Operator’s Manual and in the John Deere Easy Change service part box.

Please recycle. Many local government recycling programs, authorized retailers, auto-service centers, and auto-parts stores will puncture and recycle used oil filters and oil.

RIO switch

Mowing while backing up is strongly discouraged.

The operator who deems it necessary to keep the mower (or other implement) engaged while backing up should first bring the tractor to a stop and look behind the tractor to be sure there are no bystanders. Then actuate (push in) the RIO button. The RIO button must be held down in the reverse implement position as the shift lever is moved into reverse (reverse foot pedal is depressed on models with a hydrostatic transmission).

The operator may then release the button and the mower will continue to operate while backing up and also when resuming forward operation. This procedure must be repeated the next time the operator chooses to keep the mower engaged while backing up. If the mower power take-off (PTO) is engaged and the operator shifts into reverse or depresses the reverse pedal prior to pressing the RIO button, ignition to the engine will be shut off. The engine will stop unless the operator either pushes on the RIO switch or shifts out of reverse.

If the engine does stop, the operator must return the mower engagement (PTO) switch or lever to the off position, depress the brake pedal, and then turn the ignition switch to restart the engine.

• The mower deck is stamped from 11-gauge, 3-mm (0.120-in.) steel to provide smooth contours for a quality appearance and excellent performance.
• With no side-discharge chute, the mower can trim on either side for mowing efficiency and convenience.
  • A smaller storage area requirement is an additional benefit.
• A standard V-belt and non-timed blade design gives superior reliability and trouble-free operation.
• Offset mower blades permit blade overlap with the use of a standard V-belt drive.
  • The blades cut cleanly without being able to contact each other.
• A heavy-duty V-belt and large spring-loaded idler pulley transfer power to the mower blades efficiently and reliably.
• Four mower wheels help level the mowing job and reduce the chance of scalping the lawn.
• Cut-height increments of 0.64 cm (0.25 in.) allow for operating the mower at the optimum cutting height.
• A quick-adjust deck-leveling system is provided to make keeping the deck properly adjusted easy.

Contoured deck and discharge blade, 92-cm (36-in.) Mower for X146R shown

The mower deck is contoured and free of obstructions to ensure optimum cutting and bagging performance:

• Grass clippings flow smoothly around the deck and up the chute into the hopper.
• Clipping buildup is minimized to ensure continued high-performance and easy cleanup.
• Special discharge blades (standard equipment) have a large wing to propel grass clippings up the chute and into the hopper.
• Mower fills and packs the 300-L (8.5-bu) hopper with a large volume of grass clippings and/or leaves.

Wash port

Hose-end adapter example for use with wash port

Wash ports are provided on each side of the mower deck. They can be used to supply water to the underside of the deck so it can be easily cleaned after use:

• Wash ports are designed for a hose quick-connect fitting.
• Connect hose to the wash port on one side of the mower at a time and operate the mower to clean.
• Using the wash ports cleans bottom of deck and chute.
• Wash ports work best if used immediately after the mowing job is completed.
• Operating the mower deck while the water is running removes grass clippings.
• Use of the wash ports prevents buildup of material from affecting performance the next time the mower is used.

A hose-end adapter for the appropriate water hose to be used can be purchased locally for connection to the wash ports.

Optional rear deflector

• Plug closes off opening on bottom of deck so material cannot enter the chute.
• Special mulch blades are provided to optimize mulching performance.
• The mulching blades will also provide excellent performance when used with the rear-discharge deflector and good performance for collecting. If collecting in heavy or wet conditions, it may be necessary to reinstall the standard bagging blades for optimum performance.

X146R Tractor mowing lawn

300-L (8.5-bu) hopper is raised to empty grass

The large-capacity, rear-mounted hopper makes collecting grass and leaves easy. The rear design allows excellent maneuverability when mowing.

The 300-L (8.5-bu) capacity hopper holds a lot of material for longer mowing times between emptying. Emptying the hopper is easily accomplished from the operator’s seat.

The durable plastic bottom will last a long time, even when operating in rougher conditions.

Hopper-full sensing switch

Hopper-full indicator light on tractor dash

When the hopper is full, a light on the dash will come on and an audible alarm will sound to alert the operator to disengage the power take-off (PTO).

• When there is enough material in the hopper to activate the sensing switch, it simultaneously turns on the dash-mounted hopper full indicator light and an audible alarm.
• This reduces the potential for plugging the system.
• The hopper must be full, with enough material to activate the hopper-full switch, to activate the hopper-full indicator and alarm.

Easy-to-empty 300-L (8.5-bu) hopper

Adjustable hopper latch

The hopper is emptied by pulling up, then forward, on the hopper handle. Using the leverage of the long handle, pull forward hard enough to overcome the spring-loaded hopper latch and rotate the hopper upward.

The hopper latch is easily adjustable for operator preference and conditions:

• The spring can be located in any of three holes.
• More latching effort is required for hilly or rough operating conditions.

Front hopper support

Standard-equipment hitch

The hopper is easily removed from the tractor by using the rear handle to raise the back of the hopper 25 degrees, or about 13 cm (5 in.), and then using both handles to lift the hopper vertically out of the notches in the mounting brackets:

• No tools are required.
• There is nothing to disconnect.

When the hopper is removed from the tractor, it allows use of additional tractor features including:

• Optional rear deflector
• Optional mulch plug
• Rear implement hitch
• Tow-release lever

Interlock switches make the operator and others safer

Operator mowing with X146R Tractor

Brake pedal and parking brake lock

Safety-interlock switches are designed to help protect the operator and others. The operator must be in the seat to start or operate the tractor. The brake pedal must be depressed or the parking brake set for the tractor engine to start.

Hopper-installed sensor switch

When the hopper is removed, a safety interlock switch will prevent the mower deck from operating unless the rear deflector or mulch plug is installed, however the engine will run and the tractor will operate so the rear hitch can be used.
