Tailgate; Pickup Assembly; Bale Oversize Protection; Forming Belts - MASSEY FERGUSON MF1734 Service Manual

Tailgate

FIG. 7: The tailgate is the rear half section of the bale
chamber and is supported by a hinge at the top. The
tailgate is operated by two hydraulic cylinders to unload
the bale. The tailgate has three forming belt idler rolls and
at the bottom, a bale carrier roll.
The tailgate hydraulic cylinders are connected to linkage
that releases the latches when the tailgate is opened.
When closed, the tailgate is latched to the mainframe.
This latch must be engaged when making the bale. If the
tailgate is not latched, the tailgate will swing open as the
core is started and the core will stop rolling. The bale
must be unloaded. When the tailgate closes, the hydraulic
cylinder must be completely retracted in order to latch the
tailgate.
An indicator rod (1) operated by the right-hand hydraulic
cylinder will move out of view at the top of the machine to
indicate that the tailgate is closed and latched.

Pickup Assembly

FIG. 8: The pickup (1) is belt driven and has three tine
bars, each bar having tines for clean crop pickup. See the
Specifications section for the number of tines. The tines
extend when entering the windrow. The tines retract from
the crop as the crop is fed into the throat of the bale
chamber. Operate the pickup just high enough so the
tines will clear the ground. The pickup drive belt (2) has a
spring loaded tensioner (3) to hold proper belt tension.

Bale Oversize Protection

Overfill protection is given by declutching the pickup drive,
using a declutcher rod (4) connected between the forming
belts tension arm and the pickup drive belt tensioner arm.
The declutcher is used to prevent damage to the machine
from filling too full because of operator error or machine
malfunction.

Forming Belts

FIG. 9: The forming belts (1) are made of a high tensile
strength, controlled stretch, synthetic fabric bonded to the
covering material. The ends of the forming belts are
joined with lacing pins. See the Specifications section for
more information on the forming belts.
