The present invention relates to a multi-purpose farming machine that is used for various purposes, such as carrying goods or harvesting fruit in rural areas, fishing villages, orchards, etc. More specifically, a new type of farming machine capable of adjusting height or changing direction, etc. By implementing, the present invention relates to a multi-purpose farming machine capable of carrying out tasks such as transporting fruit crates, fertilizer sacks, or the like to harvest fruits at high places in orchards or rice fields and fields.

In general, orchard farming involves fertilizing a large number of fruit trees, spraying pesticides, and continuing to manage the fruit trees, so that fruit can be harvested from the fruit trees.

For example, when pruning a fruit tree, the first time the fruit grows, the ladder is leaned against the tree, and the worker climbs the ladder and prunes or cuts.

In addition, when harvesting fruit from the fruit tree, a long pole or a ladder is used to drop the fruit placed at a high position.

When you manage the fruit trees in the orchard or harvest the fruits like this, you need to use a ladder to climb to a high place, so it is difficult and inconvenient to work, and there is a risk of accidents such as falling.

In addition, orchards, etc. to transport the harvested fruit or fertilize the fruit trees, the fruit box or fertilizer bag at this time is a heavy weight, so it is very inefficient to transport directly to the workforce.

For this reason, most of them use tractors and the like to efficiently transport items such as heavy fruit boxes and fertilizer bags. These tractors are equipped with trailers for storing harvested crops or fruits.

However, these tractors and trailers do not have any function other than a simple transportation means, so the ladders required for fruit harvesting should be separately prepared and used, which is uneconomical and has a high risk of safety accidents when handling separate ladders.

Recently, in order to easily harvest the highly open fruit when harvesting fruits in orchards, some of the types of trailers can be lifted by hydraulic devices (lifts in the form of X bars). Due to the complexity, the cost of installation is not small, which causes a lot of economic burden.

As such, in the orchard or the like, there is an urgent need for a cart means that can be freely operated and maneuverable. In particular, such cart means must not only be capable of safe maneuvering and driving even in the rough terrain of the orchard, In order to protect the environment, there must be conditions such as no emission of pollution, but until now, since there is no cart means exclusively used for orchards, the efficiency can be remarkably improved by replacing farm machinery for other purposes or relying only on manual work. There was a problem such as deterioration.
