Page 4: Introduction
This document describes the operation and maintenance of both the tow-between and tow- behind Equalizer Air Cart. Tow-between refers to a setup where the Air Cart is hitched to the tractor with the seeding implement running behind the cart. Tow-behind refers to a setup where the Aircart is hitched behind the seeding implement. -

Page 14: Check The Air Delivery System Setup
QUICK GUIDE 5.7 CHECK THE AIR DELIVERY SYSTEM SETUP Check that the air delivery system is completely air tight. Fix any air leaks before advancing to the next step. Check that all seed metering units are set to 100% upper air lines. Check that the gear ratio of the metering units is set correctly to high or low range depending on the product application rate. -

Page 17: Telescopic Ladder
FRAME 6.2 TELESCOPIC LADDER The tow-between and tow-behind Air Carts have a telescopic ladder which can be retracted for transportation. Gas struts mounted to the top of the ladder provide additional pulling force, making the process of lifting the ladder effortless. A spring bolt ensures the ladder remains either in the lowered position or transport position. -

(marked as hydraulic drive) due to the fact that only one of these two functions are in use at any given moment. A three-way valve, located in the front left section of the Air Cart, allows for selection between these two functions. A high-pressure filter mounted upstream of the valve provides filtration. -
Page 19: Hydraulic Remote Points (Tow-Between Only)
Remote point lines. These lines are only applicable to tow-between Air Carts and are used to supply hydraulic oil, via the Air Cart, to the hitched implement at the rear. The specific codes for each of the different systems are shown on the next page. These codes... - Page 20 FRAME NOTE: Remote point 1 and 2 have ¾” hoses while remote points 3, 4, 5 and 6 have ½” hoses. Remote points 1 and 2 therefore have a higher flow capacity. It is recommended to use these hoses for the planter raise/lower function. IMPORTANT: Make sure the 1”...

Connect the quick couplers of the parking jack to the tractor’s hydraulic supply. 4. Set the height of the tow eye on the Air Cart to level of the tractor towbar using the parking jack. -
Page 23: Hitching To The Seeding Implement
HITCHING TO THE SEEDING IMPLEMENT NOTE: The below procedure refers to the tow-between Air Cart. 1. With the Air Cart connected to the tractor back the cart into position, aligning the seeding implement hitch with that of the air cart. -
Page 24: Auger
AUGER AUGER The top fill auger is driven by a hydraulic motor and feeds seed and fertilizer into each bin via the lid opening at the top. Three hydraulic cylinders position the auger for each filling position. An electro-hydraulic system which included a hydraulic manifold block and a Lodar electronic remote-control system is used to control the hydraulic cylinders (positioning of auger) as well as starting and stopping the auger. -

Page 26: Electronic Interlocks
AUGER ELECTRONIC INTERLOCKS When the auger is latched for transportation, the latching mechanism triggers a whisker switch, which prevents the system from being operate. An emergency stop switch mounted to the frame will immediately stop the auger when depressed. Emergency Whisker stop switch... -

7. Move the auger into the desired filling position by manipulating the inner and outer swing arms, being careful not to hit the auger against the Air Cart bins. 8. When in position, tilt the auger so that the inlet chute rests on the ground. -
Page 30: Air Delivery System
AIR DELIVERY SYSTEM AIR DELIVERY SYSTEM 8.1 DESIGN OVERVIEW The air delivery system work on a closed tank system where all the air fed into the system by the fan can only exit at the seed or fertilizer application points, carrying the product with from the hopper tanks. -
Page 31: Air Delivery Options
The air delivery is set up for either single or dual delivery. For a single delivery system, only one product (seed or fertilizer) is delivered from the Air Cart to the seeding implement. Air is normally supplied from a single fan and the metering units all connect to a single delivery system. -
Page 32: Component Description
If oil squirts out from the relief valve, it is an indication that something is wrong. Check that the return line is connected to the tractor. Under no circumstances should this valve be adjusted without the consent of an Equalizer representative. Air Carts with factory fit Müller ISOBUS control systems come standard with fan speed... -
Page 33: Metering Units
AIR DELIVERY SYSTEM Relief valve (20 bar). IMPORTANT: A pressure gauge on the fan motor’s inlet indicates the hydraulic pressure. Under no circumstances should the hydraulic pressure on the hopper fan exceed 15 MPa. IMPORTANT: The fan speed should never exceed 4500 rpm, due to the risk of the explosion. METERING UNITS As mentioned before, the Air Carts are supplied either with single outlet metering units or dual outlet mixer metering units. - Page 34 AIR DELIVERY SYSTEM The hydraulic motor drives the stirrer shaft through a worm gearbox which in turn drives the metering shaft through a set of spur gears. The spur gears are secured to the shafts by linchpins. These can be removed and the gears can be swopped around to achieve a low and high gear ratio.
- Page 35 AIR DELIVERY SYSTEM This adjustment allows the operator to achieve very low product application rates for fine seeds such as Canola as well as high application rates for product such as fertilizer. For most products the metering unit can be set in the high range. The mixer plate is adjusted to the desired setting by turning the knob outside of the metering unit.

Page 36: Hydraulic Variable Drive System
AIR DELIVERY SYSTEM The toolbox on the Air Cart contains a funnel bag and hanging scale that can be used when calibrating the metering unit. Calibration is done electronically from the electronic control system. HYDRAULIC VARIABLE DRIVE SYSTEM The hydraulic system which controls the speed of the metering unit, is referred to as the variable drive system. -

Page 38: Operating Procedures
AIR DELIVERY SYSTEM 8.4 OPERATING PROCEDURES REGULATING AIR FLOW IMPORTANT: Only tractors with "closed centre" hydraulic systems are suitable for this setup: Flow control on the tractor’s ports is essential. Background to the working of the system: The fan delivers an air stream passing underneath the metering units which delivers product at a calibrated rate into said air stream. -
Page 39: Sufficient Air Flow Test
AIR DELIVERY SYSTEM NOTE: Setup according to the table must be done while the Air Cart is stationary. No product may flow through the pipes while the setup takes place. The above values serve only as a guideline. NOTE: During planting/seeding the air pressure will settle at a much higher value, 2-3 kPa higher than the static setting, which is normal. -
Page 40: Equal Distribution Check On Fan Manifold
AIR DELIVERY SYSTEM EQUAL DISTRIBUTION CHECK ON FAN MANIFOLD Fan diffusers are equipped with 2 setting tabs which ensures the equal distribution of air between the various outlets. This setup is done in the factory. If the distribution is uneven, the following procedure will rectify it: Setting tabs 1. -
Page 41: Calibrating The Metering Unit
Select a container/bucket to use for calibration. Before starting with the calibration process this container must be hung on the scale (supplied in the toolbox of the Air Cart) and the scale must be zeroed. Ensure the hydraulics of the Air Cart is connected to the tractor and the tractor’s hydraulic system is in operation. - Page 42 AIR DELIVERY SYSTEM Place the container below the funnel bag. On the ISOBUS control system console, select the calibration program. Run the automatic calibration. Ensure that the metering shaft is rotated at least 20 times in order to achieve an accurate calibration. Once the calibration has stopped, ensure that all the product have run down the funnel bag into the container and that there are no hang-ups.
