Twister Mechanism Difficulties—Continued

SymptomProblemSolution

Tension break on top of bale

Force required to feed wire around bale exceeds wire strength

Reduce bale density (it may be necessary to remove side hay resistors).

Oil wire coils (light oil).

Adjust feeder fingers to put less hay on side where wire is breaking.

Use proper size wire (1.9 mm dia., 14-1/2 gauge).

Change wire coils.

 

Too much force required to pull wire from wire cartons

Check wire pulleys. Pulleys must turn freely.

Check for proper wire threading.

Make sure all of the knockout disk is removed from the front of wire cartons.

Check for any indication of catching wire.

Check front of needle for grooves or buildup of foreign material retarding wire flow.

Check for rough or uneven wire.

Check top wire guide for grooves deep enough to cause wire to wedge.

Tension break on front end of bale

Wire catches in wire pulleys

Check wire pulleys and other locations where wire could catch.

Wire breaks at base of knot

Repeated bending of wire after tying cycle because no hay is entering baler

Stop baler when no hay is being fed.

Plan windrows to avoid traveling in areas without hay.

Rake heavier windrows.

Increase ground speed.

 

Tension breaks

See .

Two successive bales not tied. (One long piece of wire with each end twisted, but not twisted together)

Bottom wire strand was missed by the needle.

Eliminate excessive side movement of needle frame. Check for properly shaped needle tip. Replace needle if necessary.

Adjust needle.

Adjust lower center wire guide.

 

Wire not placed in gripper

Adjust needle.

Wire not cutting clean

Worn or broken parts

Replace parts as necessary.

 

Gripper and shear blade assembly not adjusted properly

Place shims between top of gripper arm and mounting plate.

Wires not twisted together

Foreign material in twister assembly

Clean twister assembly.

 

Needles not adjusted properly

Adjust needles.

 

Spring seized in gripper drive tube assembly

Clean gripper drive tube.

Excessive wear on indexing surfaces of intermittent gear and pinion

Twister hooks retarded beyond maximum limits

Advance twister hooks.
