TRANSMISSION
The Kubota B7100 tractor features an unsynchronized 6-speed forward and 2-speed reverse transmission, which may pose challenges in smooth gear shifts, particularly under load. The use of a dry plate clutch allows for effective power transfer but may require more maintenance compared to wet clutches, particularly in challenging conditions. With an oil capacity of 12.2 quarts, regular checks and timely oil changes are essential to maintain optimal transmission performance, ensuring effective operation in agricultural settings.
| Type | unsynchronized gear |
| Gears | 6 forward and 2 reverse |
| Clutch | dry plate |
| Oil capacity | 12.2qts / 11.5L |
| Description | Transmission shifted using two levers. Left-hand lever selects three forward gears or reverse, right-hand lever selects high or low range |
MECHANICAL
The Kubota B7100 tractor features a robust 4x2 and 4WD configuration, making it versatile for various terrain conditions, though the lack of fully synchronized transmission may limit seamless gear shifting at higher speeds. Its mechanical wet disc brakes and rear differential lock enhance traction and control, ideal for heavy-duty applications or challenging off-road tasks. However, the open operator station may expose the operator to the elements, potentially impacting comfort during prolonged use.
