Explanation of Maintenace Checklist tasks:
- Tire Pressures: Refer to the Operators Manual for all proper tire pressures. Information will be located at the front of the manual. If you do not have an Operators manual, view our online manuals.
- Wheel Bolt/Nut Torque: Refer to the Operators Manual for all the proper torque specifications. Information will be located at the front of the manual. If you do not have an Operators manual, view our online manuals. Wheel torquing must be done using a torque wrench and not an impact wrench. Impact wrenches can damage the threads on the wheel bolts/studs.
- Transport Hubs and Maintenance: All transportation hub assemblies should be greased to ensure proper lubrication of the wheel bearings. All transport wheels on the machine will have a grease zerk on the transport hub assembly.
- Transport Caster Maintenance: All transportation caster wheels should be greased to ensure proper lubrication of the caster main pivot and walking beam pivot. All transport caster wheels on the machine will have a grease zerk on the main pivot point. Walking caster wheels will also have a grease zerk on the walking beam pivot pin.
- Transport Caster Adjustments: To adjust the main frame casters wheels, pull the machine forward. With the castor positioned (driving forward), loosen all four jam nuts on the caster pivot point bolts. Tighten the two rear bolts until they are snug ensuring left and right bolts are tensioned equally. Back the machine up so the caster is turned forward (reverse the drill). Then, tighten the two front bolts until they are snug ensuring left and right bolts are tensioned equally and the same as the rear bolts. Lastly, tighten the top jam nuts locking everything in to place. NOTE: Main frame casters will be adjusted to caster firmer than wing caster wheels. Wing caster wheels should turn freely (by hand) after adjustment. If they do not, loosen the bolts equally until they pivot freely.
- Frame Connection and Component Inspection: Inspect and check all frame components. Inspect frame fasteners and u-bolts, and all hydraulic cylinders. Inspect additional options including Lift Kit, Active Wing Braces, Smart Hitch, and Packing Force Sensor (if equipped). After inspecting all components, ensure that they are operating at proper hydraulic pressure and speeds. Incorrect hydraulic pressure can affect drill performance. Refer to the Operators Manual for all proper hydraulic pressures. If you do not have an Operators Manual, view our online manuals.
- Hitch Tongue / Pintle Hitch and Pivot Pins: Inspect and check all hitch pins to ensure that they are in place and not damaged. Ensure all keeper bolts are in place to retain the pins to manage the risk of a pin falling out. All hitch tongues and Pintle style hitches should be inspected for excess wear and stress marks. Ensure that all hitch fasteners are in place and properly secured. Replace any stressed or worn out components. Refer to the Parts Manual for parts breakdowns. If you do not have a Parts Manual, view our online manuals.
- Pivot Pins and Keepers: Inspect and check all wing folds, hitch pins and transport wheel walking pivot pins to ensure that they are in place and not damaged. Ensure all keeper bolts are in place to retain the pins to manage the risk of a pin falling out. Replace any damaged components. Refer to the Parts Manual for parts breakdowns. If you do not have a Parts Manual, view our online manuals.
- Cylinder Pins: Inspect and check all wing fold hydraulic cylinder pins and clevises to ensure that they are in place and not damaged. Ensure all keeper pins are in place to retain the pins to manage the risk of a pin falling out. Replace any damaged or worn out components.
- Packer Wheel and Hub Inspection: To inspect, start by raising the openers and inspecting for any lose wheel nuts or packer hub bolts. Spin each packer wheel and check for mud and dirt build up, or potentially failed bearings. If you have pneumatic packer tires, check air pressure. The factory pressure is 12psi.
- Air Compressor Air Filter Maintenance: The Auto Zone Command air compressor has an air filter. This filter requires regular cleaning to allow the compressor to inhale clean air. This air filter should be removed and cleaned daily in dusty conditions. A pre-filter upgrade kit can be installed for very dusty conditions (SeedMaster part # 408890). This pre-filter will allow the air compressor to draw from inside the electrical panel box. Please note this is an upgrade which can be purchased through a certified dealer.
- Air Compressor Air System: To test the air compressor, start by connecting all wire connections on the machine. Next, power the monitor on. This will start the air compressor. Ensure the compressor starts and builds air pressure in the air tank. Ensure that the air compressor shuts off after building air pressure to 105psi. The compressor will restart when the pressure drops to 85psi. Inspect the air system for any air leaks or potential air loss.
- Air Tank/Regulator/Return Air Filter: The air compressor air tank has a drain located on the bottom of the air tank. It is important to drain moisture from the air tank regularly. Moisture in the tank can cause damage to the system. There is a second drain valve located at the bottom of the air regulator by the air tank. The regulator has a clear lens to see moisture in the air system. The return air filter located on both Nova Carts and on board tanks also needs to be cleaned as it exhausts air from the Zone Command cylinders. This helps to maintain a proper operating air system.
- Zone Command Adjustments: The Zone Command disengaging and engaging arms can be manually tested by hand when the machine is stationary. This can be done by manually extending the air cylinder which disengages the Zone Command arm and engaging gear. This helps ensure the air cylinder moves freely. When letting the air cylinders go, the Zone Command arm and engaging gear should freely return back to engaged. This helps ensure that each zone moves freely and properly when the air is applied to the system. Refer to the Operators manual for all proper Auto Zone Command adjustments. Information will be located within the Tank Zone Command section of the manual. If you do not have an Operators Manual, view our online manuals.
- Drive Chain Adjustments and Maintenance: The hydraulic drive variable rate tanks drive a hex style common drive shaft. Ensure that the drive chains are aligned between both the common drive shaft and metering box. Drive chains that are not properly aligned can cause high drive pressures, excessive wear, and hard turning meter boxes. Make sure that sprockets are securely fastened and the chain tensions are not adjusted too tightly. Smooth running drives allow for smooth and accurate product rates.
- Zone Command Operation: The Zone Command is operated by air solenoids located in the panel box on either an on frame tank or a Nova tank. It can also be tested using the remote console or in cab switch box. It is important to ensure that the air regulator is set to 65psi to allow each zone to pressure and cycle ensuring free movement of the zone and proper operation. Make sure all engaging gears mesh and are properly aligned. Refer to the Operators manual for all proper Auto Zone Command adjustments. Information will be located within the Tank Zone Command section of the manual. If you do not have an Operators Manual, view our online manuals.
- Fan Inspection and Maintenance: All product delivery fans should be inspected. Ensure that the fan blade is aligned, turns freely, and is free of any dirt and bug buildup on the fan blades. Fan delivery lines should be inspected to ensure that they are free of excess moisture, product build up, or any type of obstruction. Nova Carts using high flow fans utilize grease zerks on the main drive shaft bearings. These grease points are outlined online in Service Bulletins.
- Tank and Lid Seals: SeedMaster Nova Carts operate poly-style tanks. It is important to ensure that all 2013 to 2014 tanks have tank braces installed inside the tanks for added tank support. Contact your SeedMaster Certified Dealer regarding tank bracing. Open the tank lids using the tractor hydraulics to ensure that the lid seal is in good condition. You will see an indentation where the lid seal contacts the lid frame. Next, close the tank lids, and with the fans running, inspect the tanks and tank lids for any air loss. Nova tanks must be sealed for accurate rate application.
- Product Delivery Towers: The product delivery towers should be inspected to ensure there are no blockages, excessive wear, or air loss from tower cap. 2015-2016 style towers ensure that the tower cap inserts are correct for the product type and are properly installed into the tower head. 2012 to 2014 SeedMaster towers used plastic pulse rings and should be replaced with the new steel version. See Service Bulletins for details.
- Conveyor Clean Out: Ensure that the conveyor is properly cleaned out and any accumulated product is properly removed. The clean out doors can be removed and left off allowing moisture to drain out. It is important to properly clean out your conveyor whether the cart is stored indoors or outdoors.
- Tanks Cleaned Out: Ensure to completely clean out the inside and outside of all product tanks. Make sure there is no product remaining in the tanks or meters. Start by removing the bottom clean out doors on all meter boxes. Thoroughly clean the inside of the tanks inside and out. With the clean out doors off the meter boxes, remove the bottom roller clean out plate on each side of the roller. Clean around and inside the meter box rollers, removing any accumulated product. The clean out doors can remain off the meter box while the Nova is sitting so it does not build up condensation inside the meters or tank.
- Pre-storage Maintenance: If you are washing your machine before storage, it is essential that the proper steps are taken to ensure that the components are washed thoroughly. By using hot water, soap, thorough rinsing, compressed air drying of moving components, and proper post-wash lubrication. To lubricate, apply a generous coating of penetrating oil such as Fluid Film to drive chains, sprockets, and any other appropriate moving components.
- Storage: It is recommended to keep the drill unfolded when stored for extended periods of time with all hydraulic pressure relieved. This will keep rain and snow from accumulating in the packer hub assemblies as well as help preserve hydraulic seals. Indoor storage, if available, is ideal. Hydraulic pressure on the opener cylinders should still be relieved.
