rotary compost siever, or similar (Warden Hill GL51)

Dear all, I’m looking for rotary compost sieve or something similar that could possibly help with sieving large amounts of compost at the allotment, which is hard and exhausting work if done using ordinary sieve… I’d be very grateful and happily give it a new home if you have one that’s not in use. Thank you for reading 🙏☺️
