PRESEASON CHECKLIST
Essential information about preseason prep for your Brent Grain Cart.
Checks before initial field use:
- Lubricate all grease fittings.
- Change auger gearbox oil yearly using 80W-90. Check the oil level with the vertical auger tilted all the way down.
- Ensure track auto-greaser is functioning properly if equipped.
- Verify tracks are in alignment.
- Verify torque on wheel bolts or track idlers.
- Verify tire pressure.
- Verify drive belts on double auger carts are properly tensioned and in good condition. The tensioner springs should measure 1 ¾” when belts are tensioned.
- Verify transport lights are working properly.
Checks after initial field use:
- Verify track alignment.
- Verify tire pressure.
- Verify torque on wheel bolts or track idlers.
SETUP & REFERENCE GUIDE
Brent Cart Service Points:
- Ensure that PTO is in good operational condition. Make sure that this telescopes in and out as it should and is greased properly.
- On double auger carts, check drive belts for wear. Make sure they are tensioned properly and oiled properly if applicable.
- Check gearbox oil. Ensure that oil and box is in good condition along with being filled with the proper amount of oil.
- Lubrication Points - Grease all applicable areas. Common areas of need: U-Joints/drive components, bearings, Fold pins and linkages.
- Verify drive belts on double auger carts are properly tensioned and in good condition. The springs should measure 1 ¾" when belts are tensioned.
- Flighting - Check flighting to make sure that this is not worn past an acceptable amount and is in good condition.
- Engagement Components - Make sure that the drive dog connection between the upper and the lower is not worn and significant marring is not present.
- Safety Components - Ensure safety chains, lights and SMV’s are all in good working condition.
- Hopper Components - Ensure interior of cart is in good working condition with no loose components inside.
- Tarp - Ensure tarp is free from tears and rolls freely.
- If equipped with electric tarp, please refer back to decal for specific instructions.
Double Auger Grease Bank
Undercarriage:
- Wheels: Ensure that wheel nuts are torqued to the proper spec. On new carts especially, it is critical to re-torque wheels to the appropriate spec once a load has been applied to the cart.
- Tires: Ensure that tires are in good working condition. Ensure that tires are operating at the proper pressure recommended in the owner’s manual.
- Brakes: If a cart is equipped with brakes, ensure that brakes are not dragging and are in good working condition. Make sure caliper and disk is in good shape. Make sure the tractor pulling this cart is equipped with the proper brake hook-up. Failure to connect brakes when operating may cause heat build-up and brakes to drag even though they are not connected due to oil expansion in lines.
Wheel Nuts
Tracks:
- Ensure track belt is in good working condition and free from rips and tears.
- Ensure that belt is running true and is aligned properly. We do not want any heat building up from improper alignment. After running the cart for ½ mile- 1 mile in straight course, check guide lugs for heat build-up on both sides. If heat is present make adjustments. Refer to manual for proper steps.
- Check belt tension. Current tracks are equipped with hydraulic tension. Ensure that hydraulic pressure is within 100 PSI of recommended pressure.
- Bearing and Idler Condition. Ensure wheel nuts and lugs are torqued properly. Check bearings for end play. This can be done by jacking up the track and taking the tension off.
- Lubrication: Ensure that autogreaser is set at the proper interval and full of grease. If cart is not equipped with autogreaser, ensure that grease bank lines are full and in good working condition. Grease hubs on wheels. All grease locations have purgeable seals.
Autogreaser
Scale Components:
- Ensure proper calibration number is stored in scale device.
- Ensure that all wires are routed properly and connected securely to junction block and load cells.
- For Recalibration refer to the equation below. We need to make sure we are using full cart loads. In addition to this, it is recommended to use the sum of several cart loads as this will increase our accuracy with a larger sample size.
Operation Checks:
- Ensure auger folds out and locks properly.
- Condition the tracks if they are still tacky/green rubber.
- Ensure PTO is operated at 1000 rpm actual speed (operating too slow can cause severe driveline damage).
- Verify the tarp is open before unloading.
- Ensure the joystick is connected to the same battery source as the 7-pin plug on the cart (if equipped).
- Ensure all valves on the joystick hydraulic block are locked in the neutral position (if equipped).
Tractor Hookup:
- Ensure drawbar position is 20 inches from the PTO.
- Verify the proper category hitch and pin are being used for your specific grain cart.
- Install plastic wear shoe underneath the grain cart hitch to reduce wear.
- Hook up safety chain.
- Hook up SCV hoses in the desired order.
- Set all hydraulic flows to 4-5 GPM on standard units.
- Set hydraulic flow to 4-6 GPM for units equipped with a joystick.
- If equipped with a water delivery system, set the hydraulic flow for the pump to a minimum and then increase the hydraulic flow until the water pressure reaches 40-60 PSI.
- Properly stow the tongue jack.
