The master who has used the rg40 harvester of Leiwo Valley God, please talk about the shortcomings.

The disadvantage is high fuel consumption. Sometimes an acre of land is almost 20, especially Oda is trapped again. The car is too heavy to turn slowly. Harvesting wet grain, burning the belt carelessly. The harvest cleanliness is not good, and the grain is very hairy. If the harvest speed is fast, the sieve will not win, and a pile of grain will be thrown out at once. Accessories are always changing. There are many differences between last year's car and this year's car. Then the tensioner of the chassis is not well designed, and the crawler is easy to fall off. Once in the field, the speed of reversing was a little faster, and the track was removed when the ridge slipped. Found that four people didn't install it until noon.
