Safety railings
Jam nuts on hold-down bar
Safety Railing / Ladder
Your Air Cart is equipped with a ladder and safety railings for
access to the top of the tanks. Always make sure that the safety
railings are secured in the raised position when operating the air
cart. The railings may be lowered for storage if required.
To lower the railings,remove spring pins and fold down the side
railings over the top of the tank, then proceed to fold down the
front and rear hand rails over the side rails. Reinsert the spring
pins for storage.
Product Bin Lids
The compartment lids on the air cart compartments must be
properly closed and sealed for the meters to deliver product
properly.
Periodically check the lid for proper adjustment and inspect the
seal for damage.
To determine whether the lid is adjusted properly, observe
the lid when it is unlatched. It should incline slightly toward the
latch end. A firm pull on the latch handle should be required to
over-center the latch.
To adjust the hinge end of the lid, loosen or tighten the jam
nuts on the hold down bar. (See photo)
To adjust the latch, loosen or tighten the nuts on the toggle u-
bolt. (See photo)
In the off season, it is recommended that the latch be released to
relieve pressure on the gasket.
Caution
Do not lower the railings while standing on the catwalks.
Use a suitable ladder and lower them from below. Always
have the railings raised when working on top of the air cart.
Caution
If equipped with screen baskets, do not step or lean on the
screens. They will not support a person's weight and may
fall into the tank, resulting in injury.

Using the Auger to Load Products
The auger can be used to load and unload the seed tanks. Use
the diagram on the right to help in locating the auger arms to the
correct position. Always find a level area to fill the cart, if not,
arms may be difficult to move.
To place the auger in operating position:
1. Drop the lock pin into the neutral position.
2. Pull down the spring loaded pin on the inner arm and the
outer arm into the detent position.
3. Remove the Auger from the clamp and pull the inner arm into
position by swinging the hopper away from the Air Cart.
4. Once the inner arm is in position to fill the desired bin,
release the detent pin on the inner arm and lock into place.
Pull down the outer arm pin so the auger is free to move from
the inner arm.
5. Position the auger over the lid of the tank which you would
like to fill.
Auger
Your Air Cart is equipped with an auger for loading and unloading
the product bins. The auger is mounted on a swing arm that al-
lows a flexible discharge hose to be moved to each compartment
without moving the hopper. The swing arm also enables the
auger to be turned around to unload and clean out the compart-
ments.
The auger's hydraulic drive is supplied with oil from the blower
hydraulics. A diverter valve in front of the machine directs oil to
the auger. This may be switched with the blower running.
The auger also has a three position variable speed valve mount-
ed on it to run the auger forward, backward or to stop.
A diverter valve in front of the machine selects either the fan or
auxiliary (auger and/or winch) function. Push the knob in to run
the blower. Pull the knob out to run the auger or winch.
Note
When moving to a different compartment, remember to return
the spring loaded pin into the detent position or damage may
occur.
A diverter valve in front of the cart selects fan or auxiliary (auger
and/or winch) function. Push the knob in to run the blower. Pull
the knob out to run the auger or winch.
Tip
Place the hopper on the ground in a position perpendicular to
the center tank lid. From this position the discharge end of the
auger should be able to be moved between compartments without
moving the hopper.

Using the Auger to Unload Products
1. Swing the inner arm far enough away from the machine to
allow the hopper to fit in front of the wheels. See diagram for
inner arm position.
2. Place the hopper under the meter for the compartment you
wish to empty.

3. Close the metering slide.
4. Remove the product meter door.
5. Open the metering slide to control flow from the compartment.
Note
Removing the pointer allows the gate to be opened without chang-
ing the rate setting.
Cleaning Out the Auger
1. Tip the hopper upside down to empty.
2. Run the auger backwards until the auger tube is empty.
Tip
For the rear tank, the outer arm will have to swing greater than
180 degrees in order to achieve this.

Hydraulic Systems
The hydraulic system on 5250 air carts consists of a blower con-
trol circuit, an auger control circuit, and a hydraulic meter drive
control circuit. A combination of various control valves enables
all three circuits to be powered by one hydraulic remote on the
tractor. This system was designed to function under a maximum
hydraulic pressure of 2900 psi.
Air Cart to Drill Hydraulic Couplers
(tow behind cart)
The couplers connecting the air cart to the drill/implement are
(3/4”) #12 ISO 7241 Series B, high-flow couplers. Using these
reduces the pressure drop across the coupler and enables the
operator to easily disconnect the air cart from the drill/implement.
It is important to ensure that the pressure line on the tank is con-
nected to the pressure line on the drill.
The blower motor case drain line employs a (5/8”) #10 ISO 7241
Series B coupler. This smaller size ensures that it cannot be
confused with the larger couplers.

Caution
Be sure that the case drain line on the blower motor is not
connected to pressure. Damage to the shaft seal or motor will
result.

12
The couplers connecting the air cart to the tractor are (1/2”) #10
ISO 5675 (Pioneer) tip couplers connect the blower pressure and
return lines to the tractor.
A (3/8”) #8 ISO 16028 (flat-face) coupler tip on the drill connects
the case drain line to the tractor. This line must be connected or
the blower motor will be damaged. If a case drain return port is
not available on your tractor, contact your dealer for assistance
in determining how to connect this line to the tractor's hydraulic
reservoir.
A (3/4”) #12 ISO 7241-1 Series A low-pressure return tip is
included with all Amity implements. It is also available through
Amity Service Parts P/N (69120). If your tractor has a low-pres-
sure port available, this tip can be used on the 3/4 inch blower
return line to eliminate the pressure drop caused by the 1/2 inch
Pioneer tip and the tractor's hydraulic valve on the return side.
This tip can also be used on the case drain line, if the 3/8 inch
flat face port is not available and the 3/4 inch low pressure return
port is.
Do not install a tee connecting the blower return line and the
blower case drain lines together. The blower case line must
always be connected to a direct return to the hydraulic reservoir
or blower motor failure will result.
The hydraulic line marked Pressure must be used to operate the
blower. A check valve is installed in the blower circuit to protect
the motor from an accidental pressurization of the return line and
prevents cavitation during shutdown.
Note
The 3/4 inch low pressure return tip is not compatible with the
3/4 inch high flow fittings used at the front of the cart. They
look similar, but they are not compatible.
This air cart is equipped with the hydraulic drive option that uses
electric-over-hydraulic (EOH) technology to control the meter
speed independently of ground speed. This gives the operator
the benefit of a faster calibration procedure and on-the-go rate
changing capability as well as the potential to apply product to a
prescription map using GPS.
The hydraulic drive control valve diverts 5 GPM of hydraulic fluid
flow from the right hand fan circuit to power the hydraulic drive
motors. An electro-proportional flow-control valve controls the
speed of each motor, allowing the meters to turn at speeds com-
pletely independent of each other.

Blower
The air cart's blower system generates air pressure/flow to
carry the seed or other input products through the system to the
implement. The blower is driven by a hydraulic motor and two ¾”
hydraulic lines supply oil to the blower.
The only serviceable part on the blower is the shaft seal. This
may be replaced if the motor leaks at the shaft. Do not disassem-
ble the motor to replace the shaft seal. It is secured by a snap
ring and can be removed with a seal pick.

Caution
Be sure that the case drain line on the blower motor is not
connected to pressure. Damage to the shaft seal or motor will
result.
Warning
Do not under any circumstances disassemble the motor. It is
very difficult to assemble correctly and motor destruction will
result from running an incorrectly assembled motor.
The hydraulic drive motors mount to the meter housing and
provide a direct drive of the meter shaft. The motor has a built-in
speed sensor to provide accurate meter speed feedback to the
electronics system.
Hydraulic drive Meter Drive Motor

14
The blower should be operated at as slow a speed as possible
to prevent damage to seed. If operated too slowly, line blockage
will occur. Typical blower speeds are between 3000 and 6000
RPM. Drill width, product, rate, humidity and other factors affect
blower speed.
If you do not have a run blockage monitor, carefully watch to
see that all runs are operating after changing blower speeds. To
check runs, turn meter(s) with blower running and look to see
that there is product at each ground opener.
Note
A diverter valve (2) in front of the cart selects fan
or auxiliary (auger and/or winch) function. Push
the knob in to run the blower. Pull the knob out to
run the auger or winch.
Warning
Do not under any circumstances disassemble
the motor. It is very difficult to assemble cor-
rectly and motor destruction will result from
running an incorrectly assembled motor.

Setting Blower Speed
Tip
If high rates are being applied with this implement and it is
equipped with two fans, use the fan only circuit with the low
pressure return fitting, if applicable. This will help alleviate the
backpressure in the circuit and give the maximum output.
Note
The number of outlets on the drill will directly affect the blower
rpm. The more outlets in use, the higher the pressure required to
maintain blower rpm. See your dealer for hydraulic adjustments
to your tractor, if necessary.

15
Your Air Cart utilizes a state-of-the-art electronic system to moni-
tor and control the air cart's functions. The D3 ISO Monitor sys-
tem is based on the ISO 11783 standard, often also referred to
as ISOBUS. ISOBUS is a communications standard that enables
a variety of agricultural electronics systems to talk to each other.
Its purpose is to integrate all current and future farm functions
by standardizing communication between tractor and imple-
ment. ISOBUS permits the use of the same tractor terminal on a
number of different machines and hence control of a wide range
of implements without the need to reprogram a system.
D3 System Hardware
The D3 ISO System includes a D3 electronic control unit (ECU),
which connects to a variety of sensors and an electric-over-
hydraulic (EOH) meter drive system. The ECU communicates
with a virtual terminal (VT) located inside the tractor cab. The VT
displays information and enables you to configure, calibrate and
operate multiple systems from a single user interface.
D3 Electronic Control Unit
The ECU is mounted on the air cart. It monitors all system sen-
sors and controls the meter drives. The ECU connects to the VT
in the tractor cab via an interconnecting cable that plugs into the
front of the ECU on one end and into the standard ISOBUS con-
nector on the tractor at the other end.
Virtual Terminal
The VT in the tractor cab provides a user interface for the sys-
tem, communicating with the D3 ECU and (any other ISOBUS-
compatible equipment you may add to your equipment). Your
VT could be theAmity-supplied VT, the tractor's OEM VT, or any
other ISOBUS-compatible VT.
Several companies manufacture ISOBUS-compatible virtual ter-
minals. All terminals use the same screen icons to represent the
main functions. The control screens, or pages, for the implement
(which are displayed in the central area of the screen) are identi-
cal for any ISOBUS-compatible terminal.
Currently the following virtual terminals can be used with your
ISO Drill Manager system:
• GTA Console 1 and Console 2 (AGCO)
• AFS Pro 600 & Pro 700 (Case IH)
• GreenStar2 & GreenStar3 (John Deere)
• IntelliView II IntelliView Plus II (New Holland)
• IntelliAg (DICKEY-john)
• LH6000 (TeeJet)

Blower Speed Sensor
An inductive sensor on the blower fan provides speed informa-
tion to the ECU.
Bin Level Sensor
Optical bin sensors indicate when the level of product in the
bin has decreased to the level of the sensor. The same sensor
detects all types of products. The sensor height can be adjusted
vertically to set the alarm point at any desired level.
Meter Box Flow Sensor
A capacitive sensor detects when the meter box is empty. This
indicates if the bin is completely empty, or if the product has
stopped flowing into the meter box because of bridging or a
leaky lid on the bin.
Meter Shaft Speed Sensor (Hydraulic drive)
If the air cart was purchased with the hydraulic drive option, an
integral speed sensor is provided with the hydraulic motor. This
sensor is very accurate and provides the prcise meter speed
control that is needed.
Ground Speed Sensor
This unit is equipped with a GPS speed sensor. This is used for
speed sensing only and cannot be used for mapping.

Selecting Air Stream (Dual Chute Only)
4.Switch pressurization tube to the desired stream.
Note
Do not use wrench to tighten wing nuts. Over tightening will
cause failure to stud (330031).
In dual chute equipped systems; one can switch air streams for
any desired product combination.
To switch air streams:
1.Remove wing nuts from baffle slide & plug
2.Remove slide and direct into the air stream desired
3.Replace plug and wing nuts
Note
If switching frequently:
Apply small amounts of Anit-Seize to stainless studs. This will
prevent them from seizing and breaking off.
Caution!
If the pressurization tube is not switched seeding rates
will become inaccurate.

19
The product meters deliver seed or fertilizer from the product
bins to the air stream via a fluted roller. The amount of the roller
that is being used determines the rate at which products are ap-
plied.
There are two moveable components in the meter that determine
the rate setting.
The primary setting is a flow plate adjusted by a rod connected
to a pointer. When a rate setting is selected, the pointer is simply
placed by measuring from the meter slide fully close to the de-
sired number on the tape measure. A lock bolt on the pointer rod
secures the setting.
The second part of the adjustment is the meter shut off slide. For
any rate setting the proper place for shut off slide is against the
stop on the pointer. This opens the bottom of the tank compart-
ment the proper amount for the rate setting. A ½” drive ratchet
supplied in the toolbox is used to adjust the meter shut off slide.
Any time that a new rate is set, the rate setting should be con-
firmed by calibrating the meter.
A scale and catch bag are supplied in the tool box for calibration.
Once a rate setting is determined from the rate charts and the
meter is set to that setting, perform the following calibration
procedures.
When using all of the tanks for one product, determine the
rate for each meter by splitting the desired rate by the ratio of
the tanks (33/43/24). This will result in all tanks emptying at the
same time.
Note
Plate (1) controls how much of meter roller will be
used.The shut off slide (2) is opened to the stop on the
pointer for any rate setting. When making large rate
reductions, close the slide and empty the meter to al-
low the plate to move to the lower setting. Remember
to reopen the slide until it contacts the stop on the
pointer.
Example
If you desire to seed 120 lbs of wheat using all meters, split
the desired pounds per acre rate to the ratio of the size of the
tanks. i.e. If the Air Cart is a 33/43/24 split, set the meters as
follows: 39.6 lbs (120*.33), 51.6 lbs (120*.43), and 28.8 lbs
(120*.24)
Adjusting Product Meters
Note
When decreasing the meter setting, it may be necessary to
close the shutoff slide and turn the meter to empty it. This will
empty the meter and allow the plate to move to a smaller set-
ting.

Preparing to Calibrate the Meter
Hydraulic power is needed for calibration. The following proce-
dure sets up the air cart for the calibration procedure.
1. Ensure that the air cart’s hydraulic lines are connected to a
tractor.
2. Verify that the tractor hydraulic remote for the blower is in
neutral until hydraulic power is needed.
3. Ensure that the monitor wire harness is properly connected to
the tractor.
4. Power up the monitor in the tractor.
5. Verify that the VT in the cab is communicating with theAir
Cart ECU.
6. Ensure that the meter door is properly attached to the meter.
7. Ensure the bin is at least 25% full of the product that will be
applied.
8. Set the meter gate to the appropriate position for the rate be-
ing applied.
9. Ensure the auger selector valve is directing oil to the fan/me-
ter circuit.
10.Close the blower ball-valve.
11.Actuate the tractor remote controlling the blower circuit.
12.Make sure the blower is not spinning for the following steps.
If the blower is spinning, check the ball valve to make sure
that it is full closed and blocking all flow to the blower..
13.Open the cleanout door below the meter you wish to cali-
brate.
The meter must be calibrated if:
• The gate setting has been changed
• A different product is being used
• A different meter roll is being used
Each meter must be calibrated individually, even if all the
gates are set the same.
Hydraulic Drive Calibration and Operation
Calibration is done in four parts. First, you must prepare the system for calibration. Second, you prime the meter.
Third, you take a sample and weigh it. Finally, you enter the sample, or Accumulated weight into the virtual terminal.
