This completely new generation of Trac’s, the VT7028 in a 2- and 3-axle configuration, sets a new standard in manure spreading, because of the Deutz V8 engine with 687hp, Stage 4 / Tier 4 Final, brand new Vredo CVT stepless transmission, 900/60R42 tires and up to 32,000 liter slurry tank. The VT7028 makes it possible to take big steps in the logistic process of improving and optimalisation of manure processing, because of the 32,000 liter tank and 12,000 liter/minute pump capacity with stepless speed adjustment during the spreading of manure. The VT7028 is modular designed as a 2- and 3- axle multifunctional machine with a load capacity at the front, back and on the chassis behind the cab.

Vredo with sugarbeet transportbox

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.



Vredo with wood-chipper

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, for example, a wood-chipper, which needs lots of mechanical horsepower to be driven. The hook-up of the chipper on the front can be either permanently mounted or held in the optional 3 point hitch.



Vredo with silage dozer

The Vredo Silage dozer
Thanks to its front mounted optional 3 point CAT 3 hitch system, the VT7028 is an ideal machine to be used as a silage dozer and compacter. The pump-cutter unit on the front and the tanksystem can be easily quickly removed in order to install the dozerblade and ballast weights. The VVT700 CVT transmission also makes the machine very useable as silo dozer.

Perfect weight distribution

VT7028-2 with 21.000 l. tank

The machine is designed for an optimum weight distribution over front and rear axle, so that the lowest possible tyre inflation pressure can be used on all four or six wheels. The cab is also placed far to the front so that the implement systems can be optimally positioned.



VT7028

The two axle VT7028-2 carries a lightweight polyester slurry tank of 21.000 liter, the three axle VT7028-3 carries a 32.000 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 of the pump makes sure that all larger particulates in the slurry are chopped or separated from the liquid slurry. To avoid damage to the pump and prevent the slurry injector hoses clogging up. The heavy duty 3 point steerable rear hitch with CAT 3N, 3 or 4N pickup hooks is capable of handling all kind of injectors on the market. The hitch is automatically steered in accordance with the crab steering.



VT7028 Tebbe Spreader

The VT7028’s flat and long loading platform in both the two and three axle machine builds, is an excellent place for a dry manure/compost spreader system. The mounting points are suitable for the installation of loadcells between mounting points and body. This gives optimal spreader control and monitoring of the work being done. The 2 axle machine has a 18 m3 or 20 tons spreader box, the 3 axle up to 27 m3 or 30 tons. Thanks to the hydraulic drive mechanism, the machine can be driven in the most fuel efficient way with a constant spreader drive rpm for an accurate spreading pattern.



VVT700

VVT700

Owing to the lack of a suitable CVT transmission available in the market for its new Trac, Vredo made 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, Vredo created a high efficiency and very functional transmission with three pump pads for external hydraulics, a shiftable full power mechanical PTO and continuous all wheel drive with differential locking option.

32000 Zs Flex Tank

Vredo has developed a new special slurry tank for the biggest self-propelled slurry applicator, the 3-axle with 32m3 volume; VT7028-3. 

The world innovation is that this tank is 0.5m smaller, but the volume is still the same 32m3! This is achieved by a flexible slurry bag on the top of the polyester tank which is automatically filled during the reloading process. The polyester base tank has a volume of 26m3 and the flexible bag 6m3.

The importance of the 32m3 tank volume is because the trend in the United Kingdom and the continent as well goes to more road transport by truck and trailer, which also has the max. capacity of 32m3.

With this innovation, it has been achieved that the VT7028-3 stays within the 3.00m transport width even with a dribble bar or sliding shoe toolbar up to 30m working width. This is the same transport width as the vehicle itself. With a 36m dribble bar the transport width is 3.40m.

The aim with this innovative patented construction is to increase the versatility of the biggest slurry applicator in the market, still small on the road and great in the field.



Tire pressure change system 

A tire that is too inflated, leaves a deep trial behind. That can damage the crops and the soil structure and besides, it costs more fuel. . To prevent this you drive with soft tires on the land. Are you going to drive on the road? Then it’s better to drive with hard tires. By pressing the switch just once, you control the tire pressure from within the cabin, with adjustable hard/soft tire.
