Rear hitch attachment
Three-point hitch attachment of 2
category provides coupling to tractor
mounted and semi-mounted agricultural
machinery and implements, having the
following coupling elements:
• length of suspension axle «L»
(distance between joints «
А
» and «
В
»)
equals to 870mm;
• height of machine post equals to 510
mm; 610 mm;
• diameter of pins for coupling to joints
of lift links (1) equals to 28.7 mm;
• diameter of pin for coupling to top link
(2) equals to 25 mm.
ATTENTION! Carefully study this section
before coupling machines.
Lift links consist of two parts:
• front part or the link itself;
• rear end with ball joint. Standard length
of lift links is 885 mm.
To increase the length of suspension
install lift ends with bent front joints (F70-
4605050-01/055-01).
To increase lifting capacity of hitch
attachment replace rear ends of links (of
400 mm long) with lift ends, where the
distance between joint pin and front hole
is 320mm (N50-4605040
А
2/045
А
2).
Total length of the lift link will be 805 mm.
Attention! If the link length is 805mm,
lifting capacity of hitch attachment will
increase up to 10%, with simultaneous
decrease of lift height by 10%. The
same increase of lifting capacity can
be provided by installation of brace(1)
at additional points (lift height will
decrease by 10% as well).
