<p>A small-sized transplanter trailer comprising a trailer main body (1). Sequentially arranged on the main body (1) are, alternately indented/protruded, a first ditch-digging groove (1a), a first ridging groove (1b), a second ditch-digging groove (1c), a second ridging groove (1d), and a third ditch-digging groove (1e). The ridging grooves are all trapezoidal structures. The protruding side of the first ditch-digging groove (1a) faces downwards. The downward-facing protruding sides of the first ditch-digging groove (1a) and of the third ditch-digging groove (1e) are lower than the downward-facing protruding side of the second ditch-digging groove (1c). The small-sized transplanter trailer is capable of prompt removal of excess water and dirt for the first ridging groove and the second ridging groove, thus ridge-forming is facilitated, and, as the resistance against a forward movement is small, labor intensity is reduced.</p> |
