The company Cestari has been developing and producing grain carts with auger since 1971. The factory is based in Argentina and has in the past delivered over 8.000 overloader wagon. Grain carts are also referred to as grain carts, chaser bins and other names - the function and technical features are all similar.

The Cestari grain carts are made for harsh and tuff conditions. In Argentina many wagons are used over a period of 8 month every year. They are well-tested and very firm build. Since 1999 the Cestari overloader wagon have been improved and adjusted for European conditions. In Europe Farm Mac AB and Cestari have done numerous improvements for the European market such as fitting the trailers with BPW tandem axles, Trelleborg tyres and Azco Nobel special paint.

Cestari solves problems and work properly in many different farming systems. Here are some samples of customer groups which are using the Cestari system.

• Larger farms or groups of farmers who work together. This group have more harvesters in the system which makes more logistic necessary. Distance from field to barn makes the use of trucks more cost efficient as transport vehicle of grains. (Truck transport efficiency increases significant after an average transport distance of 5 km),
• Farms located in areas with short harvest season and high moister content in the harvested grain,
• Farms which are using more than one harvester and lot of ordinary tipping wagons to serve the harvesters. (Reduction in the amount of wagons beside the harvesters in the field)
• Contractors who use their harvesters in a more efficient way to get more ha/h done,
• Farmers who decided to make a joint venture where one farmer does the harvesting and the other the logistic,
• Filling of seeder, fertilizer, internal transport of grain feed for cattle,
• Using as an overloader for feed to avoid open transport and overloading to minimize the risk of contamination of food or feed grain,
• Filling grainbags in a system with the Manero Grain Saver,

The construction of the wagon with bottom auger makes it possible to use the machine even in very humid grain (at 40 per cent moisture).

The floor hatch can be total shut over the bottom-unloading auger, which makes starts and stops easier without unnecessary PTO forces starting the auger in a chamber full of grain. The floor hatch regulates easy the flow of grain or fertilizer. The operator can see the position of the floor hatch on an indicator at the front of the Cestari wagon. The Cestari wagons are often used for filling seeds and fertilizer. This increase the advantage of handling bulk products from the barn to the field.

Increased harvester Capacity with at least 30 percent

Smaller farms with 250 ha can get a fast payback on an investment into the Cestari overloader wagon system. Other farms have to have over 1.000 of ha before they can justify the investment. The investment is based on many factors, like length of road transport, climate factors, use of the exciting equipment and logistics workforce available during harvest. Often the harvester capacity is high but the grain handling and logistic part after the harvester is not up to date.

Less wear and tear on combiners

Practical knowledge gathered around the world shows that the wear and tear of combiners are greatly reduced when a system of grain carts are applied. This comes as a key benefit since the combiner is never stopped and thus chains, bearings and such as put udner less strain. The likely savings in alrge scale farming operation is substantial!

Reduce solil compaction

With a full combiner often carrying more than 25 tons on the front axle, soil compaction is a major issue! Why otherwise would raod legislation in Europe only allow for a 11 ton/axle axle pressure when running on hard made roads? By overloading the grain continuosly to a grain cart fitted with flotation tires like Cestari, soil compaction is now a less hazzle for large scale farming operations!

The perfect tool for Mainero Grain Saver

A grain cart is the perfect tool for fast discharge into a grain bagger. This way, grain is handled in straight line from combiner, through the overloading wagon, to the grain storage without breaking kernels or risking infecting grain with for example salmonella. Since the capacity is huge on the grain bagger, the grain cart will have do do an enormous workload to keep up. The system is ideal when bagging and storing grain close to the harvested area in especially smaller, local, on farm grain depos.

Break the traditional way of harvesting

The Cestari overloader wagon is best used when it works between the harvester and the edge of the field. Overloader wagon should work in the bottom area of the field as close as possible to the road transport vehicle. The unloading wagon is working like a shuttle over the field. The harvester has to unload the grain when the wagon comes. It will be the grain operator who decides when the harvester has to unload and not the opposite way. The harvester doesn’t need to be 100 per cent full before it unload. This can reduce soilcompation due to less load in the harvesters.
