8R easy access one-piece tilt hood

Regular service and maintenance are essential to the performance, productivity, and longevity of all farm machinery. 
 
Maximum uptime is also an important element of productivity.
  • Service points are quick and simple to check.
  • Greater accessibility improves serviceability.
 All items in the daily service schedule can be performed without the use of tools:
  • Engine oil, hydraulic oil, coolant level, and the water separator can be conveniently accessed from ground level without having to open the hood
  • The engine can be easily accessed by simply raising the one-piece hood for more periodic maintenance checks
  • A single-point latch mechanism and self-contained leash ensure easy hood opening and closure.
NOTE:  Always refer to the operator’s manual for complete maintenance and service recommendations.
Typical maintenance and service information includes:

The fuel indicator will flash when approximately 60L (16 U.S. gal) of fuel remains.
 

• 680 L (180 U.S. Gal) storage on all 8R Series Tractors.
• 750 L (200 U.S. Gal) storage on all 8RT Series Track Tractors. 

Note:
• John Deere supports the usage of bio-diesel. Bio-diesel should meet ASTM D6751 (US) or EN 14214 (European) fuel quality standards.
• Tractors receive fuel containing a 2% bio-diesel blend at the factory
• Acceptable blend levels may vary by geographic region 

For more information about the use of bio-diesel in John Deere engines, refer to www.JohnDeere.com/biodiesel

The one-piece tilt hood design provides side shields and guards for additional engine compartment protection.
Hood release

Hood release

Pull out the hood release (located on the front, left side) and tilt hood back to open.
Hydraulic and transmission oil level

Hydraulic oil fill location

Hydraulic oil fill location

A sight glass for the transmission/hydraulic oil level and an oil fill neck are located at the rear of the tractor. 
 
  • Daily and 10-hour inspections of the transmission hydraulic oil level  requires operating the engine at approximately 1000 rpm for at least one minute. Stop the engine for an additional three minutes allowing  the oil to settle back into the differential case before checking oil level.
 
NOTE: The tractor should be off and parked on level ground with the hitch in the lowered position when checking oil level.
 
  • Sight glass observations will be significantly higher with hot oil temperatures and lower with cold oil or if engine has not run long enough.
 
NOTE:  Oil level above the top mark on the sight glass can result in power loss and heat generation during transport applications.

Air brake reservoir (if equipped)
 
Air trailer brake reservoir draining

Air trailer brake reservoir draining

When equipped, the air trailer brake reservoir tank should be drained of moisture before beginning daily operations.
 
A drain valve is located on the bottom of the valve so it opens when the tank drain cable is pulled.  The valve will allow any condensation collected by the reservoir to drain.
Oil cooler/condenser and radiator clean out

Primary air filter access
 
Primary engine air filter inspection

Primary engine air filter inspection

The primary engine air filter is accessible from ground level for cleaning and replacement annually or as operating conditions require.  The filter is aspirated and extends filter life in dusty conditions by aspirating over 95 percent of incoming dust.  Aspirator suction is created by utilizing the air flow from the cooling fan.
 
  • In the cab, a warning light indicates when cleaning of the primary air filter is required.
  • The air cleaner cover is easy to remove and replace
    • Clean filter using compressed air (less than 500 kPa; 75 psi)
    • Use a bright light inside of filter to inspect for damage
    • Replace filter if screen is damaged or shows the slightest rupture or hole
    • Do not attempt to clean the secondary filter
    • Replace filters at least once a year, after six cleanings, or if air filter service alert light remains on after cleaning
Oil change intervals
 
Engine oil check/fill location

Engine oil check/fill location

The 9.0L (548 cu. in.) engine features a 500-hour change interval when using approved John Deere PLUS-50 II oil and John Deere oil filter.
  • Previous initial oil and filter change at 100 hours in no longer required due to the factory oil fill of Break-In Plus.
  • If using anything other than John Deere PLUS-50 II a 250-hour change interval is required.  CJ-4 must still be used.
  • Only use ultra-low sulfur diesel fuel and CJ-4, ACEA E9 or ACEA E6 oil
  • An oil change of 500 hours is possible when using fuel with less than 15 parts per million (ppm) of sulfur, along with John Deere PLUS-50 II oil.
 
See the tractor's operator's manual for further details.
Battery access
 
Battery access

Battery access

A removable cover adjacent to the cab entry steps conceals the tractor’s two 12-V batteries (1850 total CCA).

Although the batteries are maintenance-free, conditions such as long periods of operation at high ambient temperatures and excessive engine cranking may require adding water. 

Battery boost terminal

A battery boost terminal is located on the left-hand side of the engine for convenient and proper boost-assisted starting.
Fuse and relay panel
 
Fuse panel location

Fuse panel location

The electrical fuse and relay panel is located behind the operator’s seat and just below the cab's rear window. Simply lift up on the operator manual cover for access.
  • Contains easy-to-replace automotive blade-type fuses and relays for quick servicing.
  • Spare fuses are provided for each amperage size used.
  • The diode module contains many of the diodes contained in the system:
    If a diode problem occurs, simply replace the diode module for easy service and increased uptime.
  • Relays are also fully interchangeable for quick service.
 
Electrical system (smart load center)
 
The electrical system provides a full CAN-bus based system on the tractor for improved tractor implement integration and flexibility. Incorporated with the system is a smart load center which provides fewer fuses, fewer connectors, and simplified wiring for increased reliability.
 
The solid-state load center’s primary function is to control the majority of high-current loads, such as fender floodlights and the horn. This electronic circuitry will monitor loads and voltages to provide fast reaction time and the ability to alert the operator if a circuit overloads or if voltage is out of specification, i.e. open circuit (undercurrent) or short circuit (over-current).
Cab air filters
 
Cab fresh air filter inspection

Cab fresh air filter inspection

The cab fresh air filter is conveniently located beneath the left side of the cab:
  • External service means no mess in the cab from dusty filters
  • Filter housing acts as a dust accumulator compartment
  • Hand screw eliminates need for tools
  • Replace cab fresh air filter every 1000 hours or sooner if plugged or damaged
Cab air recirculation filter
 
Cab recirculation filter

Cab recirculation filter

Cab air recirculation filter is located in the roof liner above the operator. 70 percent of the total air volume is recirculated with a “blanket effect” for enhanced operator comfort.
  • Replace cab air recirculation filter every 1000 hours or sooner if plugged or damaged.
    • Note: Intervals may vary according to operating conditions.
 
Cab air filters are not designed to filter out harmful chemicals. Follow the instructions in the implement operator’s manual and those given by the chemical manufacturer when using agricultural chemicals.
