TRANSMISSIONS OVERVIEW
The John Deere 1520 features an advanced 8-speed collar shift, a robust 16-speed two-speed power shift, and an efficient 8-speed power shuttle, providing versatile transmission options. This allows for optimal torque management and speed control, enhancing productivity across various applications such as plowing or hauling. The challenge may lie in the learning curve associated with effectively utilizing the power shift and shuttle systems for new operators.
| Description | 8-speed collar shift 16-speed two-speed power shift 8-speed power shuttle |
TRANSMISSION 1
The John Deere 1520 features a collar shift transmission with 8 forward and 4 reverse gears, allowing for versatility in operation across various terrains. The dry disc clutch provides reliable engagement but may require more maintenance than wet clutches, especially in muddy conditions. This gearbox configuration is advantageous for tasks requiring frequent gear changes, such as plowing or hauling, but can present a learning curve for new operators due to its manual nature.
| Type | collar shift |
| Gears | 8 forward and 4 reverse |
| Clutch | dry disc |
| Description | Four gears (1-4) in two ranges (I/II) plus reverse (R) range |
TRANSMISSION 2
The John Deere 1520 features a two-speed power shift transmission, providing a total of 16 forward and 8 reverse gears, enhancing versatility for various field operations. Its dry disc clutch allows for efficient power transfer but may require more frequent maintenance compared to wet clutches. This setup is ideal for applications needing precise speed control, such as tilling or plowing, however, operators should be aware of potential clutch wear under heavy use.
| Type | two-speed power shift |
| Gears | 16 forward and 8 reverse |
| Clutch | dry disc |
| Description | Four gears (1-4) in two ranges (I/II) plus reverse (R) range. Left-hand power shift lever on dash |
TRANSMISSION 3
The John Deere 1520's power shuttle transmission features 8 forward and 4 reverse gears, optimizing maneuverability for diverse agricultural tasks. The left-hand reverser lever allows for quick direction changes, but reverse is limited to the low range, which may affect efficiency during certain high-speed operations. This design is advantageous for low-speed tasks, such as tilling and loader work, but presents challenges in scenarios requiring rapid transitions from forward to reverse at higher speeds.
| Type | power shuttle |
| Gears | 8 forward and 4 reverse |
| Description | Four gears (1-4) in two ranges (I/II) with left-hand reverser lever. Reverse only available in low (I) range |
MECHANICAL
The John Deere 1520 features a 4x2 two-wheel drive chassis, ideal for lighter duty applications but may struggle on uneven terrain. Its mechanical rear differential lock enhances traction in slippery conditions, while power-assisted steering improves maneuverability. The variety of transmission options, including 8-speed and 16-speed power shifts, allows for versatility in speed control, making it suitable for various farming tasks, though the open operator station may expose the operator to the elements during operation.
