Operation and function of shock load damping system
Text-module
Functional description of shock load damping system
Pitching can be induced in tractors with heavy mounted implements by uneven tracks and roads.
The draft-sensing pins (B031 / B032) are used to measure lower-link loads in order to reduce
front-axle load changes when transporting heavy mounted implements and thus to increase
steerability.
The draft-sensing pin signals are evaluated via the EPC ECU A005
The EPC ECU A005 feeds electronic signals to the EPC controller. The signals trigger a lowering
motion which has a damping effect.

A: without shock load damping
Front axle and implement oscillate.
Text-module
B: with shock load damping
Damping lowering motions initiated by the draft-sensing pins ( B031/B032 ) reduce the oscillations.
Result: smooth roadability, safe driving

Bullet-List
Benefits of shock load damping
●
Pitching is reduced.
●
Steerability increases (front wheels do not lift so easily).
●
Travel speed can be increased.
●
Ride comfort is improved.
●
Dynamic loads are reduced.
●
Stabilisation of the absolute lift height above ground

Note:
If the shock load damping system is faulty:
Check for clearance of mounted implement (note bottom link category).
If implement coupling is faulty, draft-sensing pins (B031/B032) feed incorrect signals to
EPC ECU A005.
