Vredo Self-Propelled Trac

IN-HOUSE DEVELOPMENT Vredo is a leading manufacturer of agricultural equipment. Vredo’s regular production produces mainly four product lines: • Overseeders • Slicing Filters • Slurry Injectors • Self-Propelled Vehicles. • All these product lines are developed and produced fully in-house. To this end, Vredo is equipped with state of the art production equipment. Vredo sells and distributes her products directly and through a carefully selected distribution network both nationally and internationally. The beginnings of the company go back to 1947. At that time Mr. B de Vree, a farmer’s son,...

IN-HOUSE DEVELOPMENT MACHINE CONFIGURATIONS AXLES AND TRACTIVE FORCE STEERING & WEIGHT DISTRIBUTION VREDO SUPPORT/COLOPHON UNIQUE VREDO CVT TRANSMISSION VERY LOW FUEL CONSUMPTION LOWEST WHEEL WEIGHT ALL ROUND SUSPENSION HEAV Y DUT Y AXLES AND BRAKES THE NEXT GENERATION TRAC VEHICLE

The market demand for higher capacity applicators for liquid slurry injecting and dry-manure spreading has resulted in the new Vredo VT7028 Multi-purpose Trac vehicle in both two and three axle configurations. This new Trac has a midship installed Deutz 16 liter V8 engine with 687 hp together with the all new Vredo VVT700 CVT transmission. The VT7028 enjoys all round suspension, an all wheel steering and heavy duty axles with external disc brakes. The latest generation of agricultural tyres are able to be fitted on this new Trac. The machine also has a flat loading platform, which is...

Due to the lack of a suitable CVT transmission available in the market for its new Trac, Vredo took the decision to design its new VVT700 transmission entirely in-house. The newly developed Vredo Continious Variable Transmission, VVT700, is state of the art technology for maximum tractive effort, stepless speed adjustment and lowest fuel consumption in the industry. Combining the unique flexibility of the hydrostatic principle with the high effectiveness of mechanical power transmission, we created a high efficiency and very functional transmission with three pump pads for external...

MACHINE CONFIGURATIONS The Vredo Slurry System The two axle VT7028-2 carries a lightweight polyester slurry tank of 21 m³, the three axle VT7028-3 carries a 32 m³ liter tank and is capable to take a full trailer truck-load in one go. The pump-slicer unit is positioned at the front of the machine, which gives a perfect view from the cab of the reload operation from the pit, container or tanker. The 12.000 liter/min positive displament slurry pump in combination with the 10 inch reloading arm enables maximum capacity and flexibility under all circumstances. The Vredo slicing filter in front...

MACHINE CONFIGURATIONS The Vredo Sugarbeet transportbox Owing the multi-purpose chassis design, the VT7028 is capable of working with all kinds of systems, e.g. transport boxes for all types of materials: sugar-beets, potatoes, grains, etc. Owing to the powerful hydraulic system for external use, every type of box can be supplied with the correct flow and pressure of oil. The Vredo Wood-chipper The VT7028 has an optional full horsepower mechanical shiftable PTO to the rear of the machine. The optional front PTO is a direct drive from the engine. Both PTO’s offer the possibility to drive,...

Engine diagram Engine The Deutz TCD 16.0 V8 engine has a very compact design in 90 degrees V version. The engine built according to Stage 4/Tier 4 Final emission specification has a modular exhaust after treatment system (EAT) with SCR technology. The powerful Common Rail injection system and the electronic engine control(EMR4) with intelligent link to the VVT700 CVT transmission control, ensure optimum engine performance at low fuel consumption.

Transmission The VVT700 CVT transmission is built out of two main parts: the mechanical gearbox with planetary gearssets and couplings and the standard hydrostatic pump and motors, which are not integrated in the gearbox but mounted on the outside of the casing. The variable hydrostatic pump and motors(2) for controlling the powersplit have a displacement of 233 cm³. There are two speed ranges: 0-20km/h and 0-40/50km/h, which can be shifted under load whilst on the go. The transmission also has a shiftable mechanical PTO as standard, capable for full engine power. Three pumppads for...

STEERING & WEIGHT DISTRIBUTION Crab steering The serial crab steering enables the machine to drive with all four tires along each other, for mininal ground compaction to save the soil. Also the four wheel steer gives the machine an excellent manoeuvrability on the farm, during transport and in the field. GPS steering The optional GPS steering on a Vredo Trac is standard a Trimble or John Deere steeringsystem. Because it is completely integrated it functions perfectly in combination with crab steering.
