JOHN DEERE 870 ENGINE

The John Deere 870 is equipped with a Yanmar 1.4L 3-cylinder diesel engine, known for its fuel efficiency and reliability in various agricultural tasks. This tractor's compact size enhances maneuverability in tight spaces, making it ideal for small farms or landscaping work. However, the limited engine displacement may restrict its power for heavier implements, necessitating careful consideration of load requirements when selecting compatible attachments.

TRANSMISSIONS OVERVIEW

The John Deere 870 tractor features a 9-speed partially synchronized transmission, enhancing gear engagement and providing smoother shifting compared to its unsynchronized counterpart. This system benefits operators by reducing the likelihood of gear grinding during shifts, making it ideal for varied field conditions. However, operators must still be aware of the need for proper RPM adjustments to ensure optimal performance when changing gears.

Description 9-speed unsynchronized gear 9-speed partially synchronized

TRANSMISSION 1

The John Deere 870 features a non-synchronized 9-forward and 3-reverse gear configuration suited for various field tasks, providing versatility but requiring operator skill due to the need for a complete stop and clutch engagement during shifts. Its 225mm dry two-stage clutch offers durability, which is advantageous for heavy-duty applications, yet it may present challenges in smoother gear transitions. With an oil capacity of 22 quarts (20.8L), proper maintenance is crucial to ensure efficient lubrication and prolong the lifespan of transmission components.

Type unsynchronized gear
Gears 9 forward and 3 reverse
Clutch 225mm dry two-stage
Oil capacity 22qts / 20.8L
Description Three speeds (1-3) plus reverse (R) with three ranges (1-3). The collar shift was the standard transmission. Tractor must be stopped, and clutch used, to shift gears or ranges.

TRANSMISSION 2

The John Deere 870 features a partially synchronized transmission with 9 forward and 3 reverse gears, allowing quick speed adjustments while on the move, which enhances operational efficiency. However, shifting ranges requires the tractor to be stationary, potentially causing delays in tasks that require frequent range changes. With a 22-quart oil capacity and a 225mm dry two-stage clutch, maintenance and cooling can be effectively managed, but attention should be given to clutch wear under high use.

Gears 9 forward and 3 reverse
Clutch 225mm dry two-stage
Oil capacity 22qts / 20.8L
Description Three speeds, plus reverse, in three ranges. Speeds may be shifted on the move. Tractor must be stopped to shift ranges.

MECHANICAL

The John Deere 870 tractor features 2WD or MFWD options, providing versatility for various terrains, with the 4x4 drivetrain enhancing traction in challenging conditions. Its planetary final drives and mechanical rear differential lock offer robust torque transfer, while the power steering and wet disc brakes ensure precise handling and improved stopping power. The 9-speed unsynchronized or partially synchronized transmission provides flexibility in speed management, although the unsynchronized option may require adept user skill for smooth gear changes.

JOHN DEERE 870 TIRES

The John Deere 870 tractor offers both 2WD and 4WD configurations with various tire options, impacting traction and stability. The 4WD variant, equipped with larger front (7-14) and rear (12.4-24) tires, enhances performance on uneven terrain, making it ideal for heavy-duty agricultural tasks. Conversely, the 2WD option with wider rear tires (12.4-24) can provide better flotation in softer soils, while the lawn/turf tires facilitate versatility for landscaping applications, although they may compromise traction in challenging field conditions.
