Iseki TH4330 - Three-Point Hitch and Implement Attachment

OPERATION
47
THREE-POINT HITCH
Three-point hitch combines Tractor and implement into
one working unit. Implement position and raising are con-
trolled hydraulically. In addition, implement weight and
loads impose downward pressure at Tractor rear wheels
to increase traction.
Hitch Controls
FIG. 5-27: Control quadrant, to right of operator's seat,
controls the system to provide the following hitch control
functions:
Position Control - Maintains hitch position at constant
height in relation to the Tractor. As position control lever,
1, is moved rearward, hitch (and implement) are raised.
Moving lever forward will lower hitch to selected position.
Each lever setting provides a specific hitch (and imple-
ment) position.
Draft Control – When installed regulates hitch height to
provide constant draft, or “pull”, of ground engaging
implements (plows, subsoil’s etc.). Moving draft control
lever, 2, forward will provide deeper implement working
depth. Moving lever rearward will provide a shallower
depth. As ground contours and/or soil conditions change,
the system will raise or lower implement as needed to
keep even load on Tractor.
CAUTION: Use position control lever, 1, when
attaching or detaching implements. Place
draft control lever, 2, fully forward when
using position control.
Draft control can be installed, as an accessory.
FIG. 5-28: Lowering Rate Control - Knob, 3 controls dis-
charge rate of hydraulic oil to adjust lowering speed of
hitch and implement. Turn knob clockwise to slow drop
rate, counterclockwise to increase drop rate. Turning
knob fully clockwise will lock implement in raised position.
CAUTION: When working on or around
mounted implements, always lower to ground
prior to work. If implement must be raised,
always block implement and lower links
securely.
