Agrison HP ULTRA Series Operation Manual page 39

machinery must be lift at first and then the tractor can turn, after entering straight line
driving position, the agricultural machinery can be dropped.
2.16.3 Using of suspension mechanism
This series of tractor is connected with agricultural machinery by adopting a
three-point linkage.
2.16.3.1 Connection of the lower pull rod
There are two connection holes on the lower pull rod and the lifting rod: front hole and back
hole. Generally, the central hole will be connected during normal operation; however, the front hole
shall be connected when the agricultural machinery needs to be hung and moved for a long
distance.
The hole connecting the lower pull rod and the limit rod is the central hole.
2.16.3.2 Connecting of the lifting rod
Generally, the length of the lifting rod shall be adjusted at the central position. The adjustment
of the left lifting rod and the right lifting rod shall be uniformly implemented through rotating the
welding of the central lifting rod conduit. Rotate deasil and the lifting rod will be prolonged;
conversely, the lifting rod will be shortened. To adjust the lifting rod is mainly to adjust the lateral
level position of the agricultural machinery.
When tractors connect PTO driving agricultural implements, it is should be consider that the
rationality between tractors' suspension rod and agricultural implements. To reduce the included
angle between PTO shaft with universal drive shaft, it is usually adjusting the lift rod to the longest.
Lift rod lower long hole connect with lower pull rod pin, it make lower pull rod have a lot lever
adjustment. It is advantage of using the widest type agricultural implements.
2.16.3.3 Connection of the upper pull rod
To adjust the height of the upper pull rod is mainly used to adjust the longitude horizontal
position of the agricultural machinery and to adjust the consistency of the heights which are
ploughed by the front plow and the back plow.
2.16.3.4 Adjustment of the limit rod
The limit rod is mainly used to limit the lateral oscillating quantity of the agricultural machinery
(namely the lower pull rod). To insert the lock pin into the round hole at the front of the limit sleeve
can fix the limit rod without moving. To rotate limit sleeve with threads can adjust the length of the
limit rod. The round hole at the back side is a jack socket for placing the lock pin when adjusting
the length of the limit rod.
The amount of movement of the limit rod can be selected according to the working type of the
agricultural machinery. A certain amount of movement shall be maintained for the limit rod when
the tractor is equipped with plow, harrow, etc, which can maintain the tractor with good operation
performance. The limit rod shall be fixed without moving when the tractor is equipped with rotary
