An agriculture system (10), including: a plurality of main platforms (80A, 80B), for growing plants thereon, each including two subsidiary platforms (56A, 56B) being pivotally (72) connected one to the other； a belt (54) and a motor (40) for rotating the belt (54) about a bottom wheel (42A) and a top wheel (42B), for lifting and descending the main platforms (80A, 80B)； and a folding mechanism (108) for folding subsidiary platforms (56A, 56B) one in relation to the other about of the pivotal connection (72) upon being located near one of the bottom (42A) and top (42B) wheels, for avoiding proximate main platforms (80J, 801) from encountering one another, thereby the folding mechanism (108) allows the width (62) of each of the main platforms (80A) to be almost the diameter (64) of each of the bottom (42A) and top (42B) wheels.
