The tractor used with the E6910 unloader
should have no less than 60 HP.
Hydraulic circuit can be either open loop or
closed loop.
The PTO drive shaft should not exceed a 360
millimeter (14”) length, measured from end of
PTO stub shaft to drawbar hitch pin (Fig. 1) This
is to ensure adequate torque transference
between the two sections of the drive shaft.
A 12V electric hoist is used to raise and place
bag in position on the tunnel hood, so the tractor's
battery should provide that voltage.
Hitch pin “A” should be 30 to 32 mm. (1 3/16” to 1 1/4”) in
diameter and have its corresponding retaining clip “B” (Fig. 2).
A spacer should be placed between hitch tongue and drawbar
to prevent vertical rocking motion.
