My grandfather ran an orchard he inherited from his great-grandfather. He produced apples, Japanese pears, and Western pears. I believe this was used for pruning branches during the snowy season. I remember wearing kanjiki (snowshoes) and pulling it with a traction belt slung diagonally from my shoulder to my armpit, and it slid very lightly and smoothly. After the New Year, when the snow began to accumulate in the mountains, our fun was sliding down the slopes of the orchard. We competed to see who could slide down without hitting their heads on the apple branches and without falling on their bottoms, keeping our posture low. After the Little New Year (January 15th), when the snowfall became heavy, branches scattered on the snow surface from pruning work, and we could no longer ski. The material is very hard wood. The concerning point about the condition is a crack in the part of the sled that carries the load on one side (images 11 and 12). There is also a diagonal chip on the upper end, but this is where the surface layer has peeled off. It came off when I scrubbed the dust with a car wash brush. In addition, there is corrosion on the tip of one of the sleds (images 5 and 8). The dimensions are: the length of the sled's sliding surface is 155cm, the straight-line distance from the tip to the rear end of the sled is 150cm, and the width of the sliding surface is 8cm. From the sliding surface to the cut-in part of the loading platform, which is slightly lower, is 12cm, and to the slightly higher parts before and after that is 13cm.
