系列四轮驱动拖拉机在田间重负荷作业或在潮湿松软土壤上工作，若只靠后轮驱动，
拖拉机的牵引力可能不足，此时挂接前驱动桥可以增大拖拉机的牵引力，降低打滑率，从而提高拖拉
机的作业适应性。为了便于接合和分离前驱动桥，应遵循下述操纵程序。
SHUHE SH 90series of 4-wheel drive tractor can make heavy-duty operations in the field or on the wet and
soft soil. If only rear wheel acts to drive, the traction performance of the tractor may not be enough. Now
front drive axle can be used to increase the traction force and decrease the slippage so as to improve the
operation adaptability of the tractor. In order to engage and release the front axle. the following operation
sequence should be followed:
4.8.1
前驱动桥的挂接
Mount front drive axle
踩下主离合器踏板，挂好变速箱档位，然后慢慢松开离合器踏板，待拖拉机稍动时，及时向上拉
动前驱动桥操纵手柄（前一页图中序号
1
）
，使两轮驱动变为四轮驱动。
Step on main clutch pedal and engage the gearbox shift, then release clutch pedal slowly. After the tractor
moves a little, pull up front drive axle control handle backward immediately and change two-wheel drive into
four-wheel drive.
4.8.2
前驱动桥的断开
Disconnection of front drive axle
需要断开前驱动桥时，踩下主离合器踏板，向下推动前驱动桥操纵手柄（前一页图中序号
1
）
，使前驱
动桥分离。
When it is necessary to disconnect the front drive axle, you need to press the main clutch pedal to the floor,
push the front drive axle control handle down to disconnect the front drive axle.
重要事项：
IMPORTANT:
拖拉机在硬路面作一般的运输作业时，不允许接合前驱动桥，否则会引起前轮过早磨损，增加燃
油消耗。只有当雨雪天气，路面较滑，上大坡后轮容易打滑时才能接合前驱动桥。当拖拉机驶出
困难区段后，应将前驱动桥分离。
The tractor will run out of the slip area with the same rotating speed when the tractor transports on the
hard road, it is not allowed to connect front drive axle. Otherwise, it will result in early wear for front
wheel and oil consumption increase. Only in rainy or snowy days, which road is comparatively slip and it
is easy to slip when climbing the large slope, the front axle can be connected. When the tractor gets out of
adverse circumstances, front drive axle shall be disengaged.
拖拉机运输作业时，前轮胎磨损较快且轮胎花纹左右两侧磨损不均时，可根据情况将左右轮胎调
换使用。
When tractor performs a transportation operation, front wheel tyres wear rapidly and left/right sides of
tyre tread patterns are worn unevenly, therefore, it's possible to exchange the left/right tyres.
