Why should I invest in a new grain bin sweep?
New grain bin sweeps excell in safety and efficiency. Older sweeps often require you to enter the bin to hook up cables, adjust tracks, or manually push the equipment when it gets stuck. The modern sweeps at Custom Agri Systems, Inc. supplies allow you to clear the bin floor entirely from the outside. Upgrading your grain sweep protects your people and cuts down on the time it takes to switch bins.
How much labor time can a modern sweep actually save me?
Modern grain bin sweeps save a lot of time. Traditional, older sweeps often require hours of manual shovel work to clear out the dead spots and corners that the machine misses. Modern sweeps feature advanced reduction drives, aggressive flighting, and rubber scrapers that leave a clean floor pass on the very first round. What used to take a crew a full day of shovel work can now be completed automatically in a fraction of the time.
My old sweep still turns. How do I know it’s actually time to replace it?
Frequent Slipping: If the wheel or drive mechanism slips whenever it hits a heavy pile of grain, it’s slowing down your entire operation.
Worn Flighting: If the edges of your auger flighting are thin or curled, the machine’s capacity is reduced. This increases the running time to move the same amount of grain.
Frequent Repairs: If you are constantly replacing chains or unfreezing gearboxes every time you open a bin, you are losing money on downtime.
What's the difference between an auger sweep and a paddle sweep system?
Standard auger sweeps use a screw conveyor to move the grain. Paddle sweeps use a heavy-duty chain with plastic or rubber paddles to drag the grain. Paddle sweeps are gentler on easily damaged crops, like seed corn or specialty soybeans, compared to auger sweeps.
