a retarding force. Keep towing vehicle in gear at all times. Slow down for corners and rough terrain.
•Make sure you are in compliance with all local and state regulations regarding transporting equipment on
public roads and highways. Lights and slow moving signs must be clean and visible by overtaking or
oncoming traffic when feeder is transported.
•SAFETY CHAIN - If equipment is going to be transported on a public highway, a safety chain should be
obtained and installed. Always follow state and local regulations regarding a safety chain and auxiliary
lighting when towing farm equipment on a public highway. Be sure to check with local law enforcement
agencies for your own particular regulations. Only a safety chain (not an elastic or nylon/plastic tow strap)
should be used to retain the connection between the towing and towed machines in the event of separation
of the primary attaching system.
•Install the safety chain by crossing the chains under the tongue and secure to the draw bar cage or hitch or
bumper frame.
•Beware of bystanders, particularly children! Always look around to make sure that it is safe to start the
engine of the towing vehicle or move the unit. This is particularly important with higher noise levels and
quiet cabs, as you may not hear people shouting.

PERFORMING MAINTENANCE
•Do not allow anyone to perform maintenance on this equipment who has not been properly trained in its
safe operation.
•Good maintenance is your responsibility. Poor maintenance is an invitation to trouble. Proper servicing
and adjustments are key to the long life of any implement. With careful inspection and routine
maintenance, costly downtime and repairs can be avoided.
•Some parts and assemblies can be quite heavy. Before attempting to unfasten any part or assembly,
arrange to support it by means of a hoist, by blocking or by use of an adequate arrangement to keep it
from falling, tipping, swinging or moving in any manner which may hurt somebody or damage the
equipment.
•Always use lifting equipment that is adequately rated to do the job. Never lift equipment over people.
•Make sure there is plenty of ventilation. Never operate the engine of the towing vehicle in a closed
building. The exhaust fumes may cause asphyxiation.
•Before working on the equipment, stop the towing vehicle, set the brakes, disengage the PTO and all

Stack Lock Adjustment
The BIGHAM Ag Stack Fold Hipper Implement is equipped with the BIGHAM STACK LOCK feature. This feature
helps lock the two lift arms together when the Implement is in the Stacked (folded) position. To ensure that this Stack
Lock Feature is always engaged, there has been some adjustment built into the assembly. To make those adjustments,
please refer to the steps below.
STACK LOCK not engaging properly (i.e. not meeting in the middle) –
- With the arms in the folded position, take a measurement of how far the components are from touching.
- Fold the arms down, and add shims as necessary to close the gap between the male (Figure 2) and female
(Figure 1) sides of the Stack Lock assembly. Longer bolts may be needed as shims are added.
- Stack Lock Assembly should engage just before the arms are fully folded to ensure a proper engagement.
STACK LOCK alignment is off vertically or horizontally –
- Slightly loosen the bolts of the male & female components. Both mounting plates are slotted in opposite
directions. Move the plates as necessary to ensure proper alignment.
- Fold the arms and make sure that the alignment is correct, then unfold the arms and tighten the bolts.
Figure 1 Figure 2
Figure 3 (STACK LOCK engagement)
Storage Stand Use
The adjustable storage stands on the back of the hipper are designed to be used when the unit is not in field
operation. FAILURE TO PROPERLY RAISE AND PIN THE STORAGE STANDS WILL RESULT IN DAMAGE TO THE
STANDS, AND POSSIBLY THE HIPPER FRAME, WHEN OPERATING THE HIPPER IMPLEMENT!!

Bigham Ag Stack Fold Hipper Page | 19
Furrowing Plow Adjustment
The Hipper Implement is equipped with an adjustable foot piece for mounting the furrow plow. Different size
plows with different bolt configurations can be mounted to the foot piece for different field conditions. The type of soil, the
soil conditions, and the speed of the tractor can all contribute to the type of furrow needed for each farming operation.
Slotted sweeps come standard with the Hipper Implement, but if the Hipper Implement is equipped with a single mounting
bolt in the plow, make sure the furrowing plow is aligned properly with the furrow shank. If the plow is mounted with a tilt
to one side of the shank it could result in the furrowing plow throwing more soil to one side of the furrow than the other,
creating undesirable seedbed formation.
Setting the Furrowing Plow Depth
Each Hipper Implement comes from BIGHAM with a specific set up on the furrowing plow depth. A general good
initial setting is with the Hipper Implement drum, chopper, or tumbler basket 4” to 4.5” from a good flat surface when the
furrow plows are evenly touching the same flat surface. Depth of each assembly can be adjusted individually by
loosening the stud bolts (shown in Figure 4) of each furrow assembly and lowering or raising the shank to the desired
depth for the application. Always tighten the stud bolts properly prior to operation of the Hipper Implement to ensure the
Furrowing Plows keep the desired adjustment.
Figure 4
Maintaining Furrow Depth
It is critically important to maintain a uniform depth to the furrows created by the Hipper Implement. Maintaining
the depth of the furrow can be done by adjusting the two (2) gauge wheel assemblies provided with the Hipper Implement.
Adjustment procedures for the gauge wheel assemblies are shown on pg. 14 of this document.
Linkage Arm Adjustment
To create a more desirable seedbed, your BIGHAM Hipper Implement may be equipped with a set of rear basket
assemblies attached to the Hipper Implement Frame with a set of Adjustable Linkage Arms (Figure 5). These arms allow
adjustment for both height and down-pressure to assist in the formation of a proper seedbed for planting. Adjustment for
those two variables is described below.
Linkage Arm Height Adjustment –
Each Linkage arm can be moved upward and downward on the mounting tubes on the rear of the Hipper
Implement frame. This adjustment is made by loosening and removing the two bolts attaching the arm, raising or
lowering the arm as desired, and re-inserting the two bolts into the next set of alignment holes. Make sure to
tighten the bolts once the desired adjustment is complete. Linkage Arms Must be adjusted in pairs, or the arms
will not move.
Spring Down-Pressure Adjustment –

Bigham Ag Stack Fold Hipper Page | 20
Each Linkage arm also has a built in down-pressure spring to ensure that the rear tumbler baskets stay engaged
with the ground and prepare the seedbed correctly. If more down-pressure is desired, tighten the spring bolt by
turning the nut clockwise. If less down-pressure is desired, loosen the spring bolt by turning the nut counter-
clockwise. When decreasing the pressure, do NOT loosen the nut past the nylon insert in the nut.
