Round Bale Feeder Cover, Clyven

The Clyven Round Bale Feeder Cover is built for most feeders under eight feet in diameter. It features a large top cover and a Western farm industrial design that emphasizes durability and outdoor practicality. Best for operations with standard 8 ft feeders, this cover helps keep hay dry and cleaner, reducing feed waste by up to 40% by shielding against rain, wind, and trampling. The fabric is 420D Oxford with a thick waterproof coating to withstand rain and sun exposure. A potential limitation is that it may not fit feeders larger than 8 ft, so measure before purchase.
Breathable Green Hay Cover 32′ x 41′

This generic, breathable tarp emphasizes airflow to keep hay cool and moisture able to escape. It’s water-resistant and wind-resistant enough to minimize wind flap during installation. Best for buyers prioritizing ventilation and a lower purchase price, it may be less robust in extreme weather and should be checked for proper fit on non-standard round bales.
CrystalSylara 5.5ft Round Hay Bale Cover

CrystalSylara offers a 5.5 ft round bale cover tailored for standard round bales and ring feeders. It uses double-layer waterproof PE with reinforced hems to prevent leaks and edge fraying, ensuring a snug wind-resistant fit. This option is best for mid-sized bales and feeders; avoid it if you have larger or smaller feeders, as fit may loosen on sizes outside 5.5 ft.
Weathermaster HD2536D Heavy Duty Hay Bale Cover

Weathermaster HD2536D is designed for rugged outdoor use with heat and cold resistance. Its heavy-duty construction makes it suitable for year-round protection in demanding environments. Best for frequent exposure to harsh weather, but the heavier build may be less convenient for smaller operations or quick setup.
Woanger 20′ x 48′ Heavy Duty Hay Tarp

The Woanger hay tarp is a large, heavy-duty option designed for long outdoor storage of hay stacks and round bales. It features a 260 GSM polyethylene construction with a 1200D double-layer design, plus UV resistance for extended sun exposure. Best for vast storage needs, but its size requires ample space and a secure setup to manage wind.
Caution: Ensure proper anchoring in windy locations to prevent flapping or tearing. This tarp is best paired with reinforced corners and tie-downs for durable use.
Buying Guide
What to consider when choosing hay bale covers
- Size and fit: Measure bale diameter and feeder compatibility. Choose a cover that fully encloses the bale without excessive slack.
- Material durability: Look for UV resistance, waterproof or water-repellent coatings, and reinforced seams to extend outdoor life.
- Weather protection needs: For frequent rain or snow, prioritize heavier fabrics and double-layer construction. For windy locations, wind-resistant designs with drawstrings or buckles help secure the cover.
- Ventilation vs. moisture control: Breathable fabrics prevent condensation for drier hay, but fully waterproof covers prevent leaks. Assess climate and storage duration to balance airflow and protection.
- Ease of use: Simple installation and securing mechanisms save time during field work. Consider covers with clear channels for ropes or cords.
- Portability and storage: If you move bales often, lighter covers are easier to handle but may offer less protection. Check if the cover folds neatly for off-season storage.
- Compatibility with feeders: Some covers are specialized for ring feeders or specific bale sizes. Always verify compatibility with your equipment before purchase.
