BE A SAFE OPERATOR, THINK BEFORE OPERATING.
READ ALL INSTRUCTIONS BEFORE
ASSEMBLY OR OPERATION OF THE CULTIVATOR!
INTRODUCTION:
The Model 888 Cultivator/Lister has two primary functions: cultivation of growing crops and pre-plant bedding
operations. Independent parallel-linked gangs assure consistent operation over uneven ground.
When congured as a cultivator, a combination of sweeps and barring-off discs clear weeds from areas between
rows of growing plants.
For bedding operations, busters, lister bottoms, or bedding sweeps are mounted on the shank at the rear of each
gang.
In irrigation trench operation, a small buster, shovel, or point replaces the buster or bedding sweep used in bedding
operations.

BIGHAM BROTHERS, INC.
The BIGHAM BROTHERS Model 888 Cultivator is
equipped with an uneven number of parallel linkage
tooling gangs—one for each crop seedbed plus one.
Normal conguration includes a leading trash-cutting
coulter with depth band or height adjustable tire, a center
swivel coulter, sweeps or barring-off discs, and a rear
chisel shank with bedding or cultivating tools.
Gang Placement
Check/set row spacing from the center line at the point
of the sweep, buster, or irrigation shovel—not at the top
of the clamp on the tool bar. Manufacturing tolerances
may affect position at the end of the tool. Set center gang
between two stringer plates. Ensure center of sweep or
buster is on center. Run a tape from center point and
ensure each point is the right distance from this point.
For example, for 38” rows, points should be at 38”, 76”,
114”, 152”, 190”, 228”, etc. from the center point. Do not
measure one point to the next, because any error can be
compounded to the next gang.
Set chisel shanks all the way to the top by adjusting the
4x4 mounting tube to its upper-most position.

Mount Gangs to Tool Bar
Two types of gang mounting assemblies are available: the Rear Mount assembly and the Wrap-around assembly.
Each is fastened by use of two u-bolts for each gang. See pictures 1-5. Position each clamp so the gang is centered
between the crop rows. Note alignment cuff on rear mounted clamp assembly. If equipped with screw jack, ll the
jack cavity with grease once each season through the grease zerk in picture three.

Set Operating Depth: Front Tire or Coulter
Gang operating height is set by either an adjustable depth control tire or one of several front-mounted residue
cutting coulters. Rigid and Swivel Coulters mount directly to the gang and do not adjust vertically. The Adjustable
Coulter and Adjustable Tire allow vertical adjustment via the screw jack (picture 8).
Using the adjustable coulter or tire allows working height of the gang independently of the other tooling.
Note: Adjust gauge wheels or three-point lift so the parallel linkages on the gang are level at operating depth.
If hard ground prevents the tool from fully engaging, install down-pressure spring kit. Failure to give the gang
proper up and down travel range can result in damage to coulters, wheels, tooling, and gang.
On a gang with rigid coulter or xed swivel coulter, all tooling heights are set to the coulter.
Scrapers are available to keep wet soil from sticking to coulters (picture 10).
See pictures 6-10.

Rear Shanks
The cultivator gang mounts a chisel shank featuring Bigham Brothers’ No-Twist™ foot piece. Note the rear mounting
tube that may be adjusted vertically with four ange bolts. Start by moving the
The rigid shank mounts directly to the chisel shank mount tube at the rear of the gang. If you are mounting a 1x3”
straight shank with a clamp, request the mounting tube, part number 689-244 without the chisel shank guides.
The Spring Reset Chisel Clamp attaches a chisel shank to the rear tooling tube through an automatic spring reset
mechanism. Note the three spring mounting positions that give pressure settings of 400, 800, and 1200 pounds. See
special mounting instructions on next page.
See pictures 15-18.

The Spring Loaded Chisel Clamp should be assembled when you receive it. How-
ever, you will need to partially disassemble it to mount it on the 4x4 tooling bar.
When assembled, the chisel shank clevis obscures the bottom end of the u-bolt
(#1) which secures the clamp to the 4x4” bar. To install the nut, you must rst
remove the pivot bolt (# 2). The nut will be left loose from the factory. You may
need a hammer and punch to drive the bolt out and align the clevis when you are
ready to reinsert the bolt.
When the bolt is removed, swing the clevis back out of the way (# 3). Make sure the bushing does not fall out. Insert the
u-bolt, and securely fasten the clamp to the 4x4” bar (# 4). Realign the clevis. Use a tapered punch or other tool to align.
DO NOT ALIGN THE CLEVIS WITH YOUR FINGER. Reinsert bolt and lock washer, then tighten to 150 foot-
pounds.
Grease the clevis at the grease zerk (# 1) and periodically thereafter.
Note that point pressure (trip pressure) is set by positioning the spring assembly in the proper holes in the clevis. The
front holes (# 6) set the pressure at 400 pounds. The center holes (# 7) set pressure at 800 pounds. The rear holes (# 8) set
it at 1200 pounds.
The spring pressure is set at the factory with adjusting nuts on top and bottom. The distance between the inside of the top
bracket (# 9) and the bottom cap (# 10) should be set at 17-1/4 inches plus or minus 1/8 inch. The spring pressure is set
at the factory and SHOULD NOT BE ADJUSTED IN THE FIELD. Adjusting spring pressure will result in changing
operating angles and tool alignment.

Warning! Position barring-off disc hubs as detailed below.
Barring-Off Disc Hubs Mounted on Cultivator Gangs
Description:
(1.) Covering Disc Hubs MUST run in the correct direction or the spindle bolt will work loose, resulting in loss of
disc and bearings. The spindle is fastened with either a left-handed or right-handed bolt. It MUST be installed on the
proper side of the row to insure that the bolt stays tight during operation.
(2.) Spindles are different on left- and right-handed hubs (left-handed bolt/right handed bolt).
(3.) Spindles are made to run with EITHER a Link Belt/BBI Premium bearing OR a Fafnir (a few older models)
bearing. They will not interchange.
Right-hand hub on LEFT side Right hand bolt with red marking Left hand spindle detail
Identication of Left-Hand and Right-Hand hubs
Hubs are made left- or right-handed by the Spindle Bolt. Upper right shows marking on the hex spindle shaft. There
are three markings:
(A.) F/L: The spindle marked ‘F’ takes the Fafnir bearing only. The ‘L’ spindle will use either Link Belt or BBI
Premium bearings. Order bearings accordingly.
(B.) LH/RH Marks spindle as either Left-Hand or Right Hand. This refers to the direction the spindle bolt tightens.
A left-hand spindle uses a left-hand thread spindle bolt. A right-hand spindle uses a right-hand thread spindle bolt.
The right hand bolt may be marked with RED paint.
(C.) Soil Flow Direction - The arrow points to the REAR of the machine.
Cultivator Field Installation Instructions:
Locate the barring-off disc assemblies as shown in the photo at left. Note that the
hub with the right-hand bolt is placed on the left side of the gang as seen from the
rear. The right-hand bolt points right and the left-hand bolt points left as seen from
the rear of the plow.
Note: If you reverse the direction of soil ow (ex. move soil toward row instead of
away from row), move disc to the opposite side of the gang so the hub is facing the
same direction in relation to the plow.

Attaching Tractor to
Model 888 Cultivator
Choosing the proper tractor:
1. It is extremely important to utilize a tractor with
sufcient horsepower and traction. Soil conditions and
tooling (i.e. bedding tools vs. cultivator sweeps) will
effect horsepower requirements, but allow 10-30 HP per
row, i.e., 4 rows requires a 40-120 HP tractor.
2. The Model 888 Cultivator is equipped with rear-
extending gangs. The three-point linkage of the tractor
must allow 36 inches between the ground and the lower
hitch points in the “fully raised” position to provide
adequate transport clearance.
3. Ensure that both the right and left lift arms are
identical in length, and the tool bar is level (right to left).
They must be equal to achieve uniform operating depth
and transport clearance.
4. Sway blocks or stabilizing chains should be adjusted
to minimize lateral movement.
5. Insure tractor has sufcient front end weight to permit
constant positive steering at all times.
6. Insure tire pressures are equal and set at
manufacturer’s recommended pressures.
CAUTION
NEVER STAND BETWEEN TRACTOR
AND MODEL 888 CULTIVATOR WITH THE
TRACTOR ENGINE RUNNING.
A. Tractors Equipped With Quick Hitches:
1. Attach quick hitch to the Model 888 Cultivator and make
sure lower pin locks are secured.
2. Raise the parking stand into the clamp body or remove to
allow the Model 888 Cultivator into a working position.
3. When disconnecting the Model 888 Cultivator adjust stands
to leave the Tool Bar tilted slightly forward. This will permit
easier disconnecting and reattaching.
WARNING: Never Work under the Model
888 Cultivator When it is in the raised position.
Always lower the unit to the ground before
making any adjustments.
Tractors Without Quick Hitch:
1. Attach lower lift arms of the tractor to the Model 888
Cultivator utilizing appropriate pins. Standard equipment for
all units is a Category III wide hitch with 1-7/16” Lower and
1-1/4” Upper Pin diameters.
2. Attach top link after connecting lower lift arms. Raise
parking stands into clamps or remove. When disconnecting,
place stand to leave the Model 888 Cultivator in a stable
position.
CAUTION
DO NOT MOVE TRACTOR WITHOUT
MAKING SURE TOP HITCH IS
CONNECTED TO TRACTOR.
Field Use and Adjustments
NEVER ALLOW ANYONE TO
RIDE ON THIS EQUIPMENT
DURING OPERATION
1. Maximum operating speed 4 - 8 mph. If obstructions
are present, lower operating speed to a safe level. This
will help minimize damage.
2. Adjust the depth by raising or lowering the depth
control wheels.
3. The frame must be horizontal (level) front to back
when in use. Adjust by lengthening or shortening the
tractor’s top link.
4. Check and adjust if necessary the coulter position in
relation to the tillage shank working depth.
5. Never reverse the tractor when the Model 888
Cultivator is in the ground.
6. Do not make sharp turns when the Model 888
Cultivator is in the ground.
7. For best results make sure to operate on matching
rows.
