The Claas Matador Gigant harvester you've mentioned seems to be a powerful and efficient machine with a decent capacity for both fuel and grains. With its 90HP engine power and a maximum speed of 19.5 kph, it can handle a variety of harvesting tasks effectively. The 150-liter fuel tank ensures that you can work longer without frequent refueling stops, while the 2150-liter grain tank capacity allows you to harvest more before unloading.
In terms of cutters, the Cutter 420 offers a wide working width of 4.2m, albeit at a slightly slower working speed of 5.5 kph. This cutter would be suitable for larger fields where efficiency is key. On the other hand, the Cutter 300 has a working width of 3.0m but operates at a faster speed of 7 kph, making it more suitable for smaller or more intricate fields. Both cutters come at reasonable prices, with the Cutter 420 priced at $5,500 and the Cutter 300 at $4,500.
The configuration options of adding a beacon light and cabin provide additional functionalities and comfort during operation. However, it is worth noting that the Interactive Control mod is necessary for fully utilizing the features and functions of this equipment.
Overall, the Claas Matador Gigant with its available cutters and optional configurations seems to offer a well-rounded harvesting solution for a reasonable price of $17,500.
