Vervaet Beet Eater - Model 925 - Sugar Beet Harvester
From Manure Processing
Vervaet is a family business that started in 1974 by building self-propelled beet harvesters. The first Hydro Trikes were developed in 1989. Currently, more than 180 people work for Vervaet, making sure that clients from all over the world get their Q616, Q621 and their Beet Eaters 625 and 925 on time. The production of these machines takes place between February and September while the rest of the year, the staff work hard on the production and timely delivery of the Hydro Trikes. The factory premises cover 50,000 m2 nowadays, of which 13,500 m2 has been built on. Vervaet invests almost 10% of its turnover in research and development (R&D) and produces 75 to 100 new self-propelled machines every year.

Product Details
In 2001, to stay ahead of the competition, and to keep sugar beet lifting profitable in the future, Vervaet introduced the 'Beet Eater', the first 9-row ,tanker sugarbeetharvester in the world.
Capacity has proven to be at least 50% more then the conventional 6-row machines. Up to 3 Ha (7,5 acre) per hour is possible
New constructions (Patent applied for) have been developed, unique for sugar beet harvesters. On the Agribex agricultural show in Brussels, we won the prestigious 'gouden aar'
Let us go through the machine from the front to the rear.
Why the Beet Eater 925?
- Maximum capacity
- Minimal maintenance costs
- Full width equal hit
- Big tires for minimal ground pressure
- Variable Adjustable row distance 45-50 cm
- Agile
- Not too wide on the road (max 3.50 m)
Lifter
3x3 is 9…
Obviously, the lifter needs to fold-up for road transport too. This one folds up in 3 parts (3 x 3 rows) This lifter can bend down a little more then horizontal,so when the land is not flat, it can still maintain a shallow lifting depth.Each side of the lifter has it's own depth control,as well as the middle section,which has a left and right depth control, like the conventional 6-rows. Both side-sections are also provided with an automatic rowfinder. They can move left and right for about 15 cm (6 inches) on top of the 8 cm which each element could move already, solving the problem of beet being drilled with 6 or 12 row drills. It is even possible to lift only 6 rows, simply by lifting up the right hand side section. The shares are driven separately, by hydraulic motors, instead of v-belts.
Behind the lifting shares are 3 turbines (1,35 meter on the sides and 1,85 meter in the middle) Due to the ideal turbine configuration, the beet flow is just perfect and the length of topper + lifter are nearly the same as the 6-row 17-Tonner. Hydraulic 45-50 cm (18-20 inch) row-width adjustment from the cab is optional. Other row widths are possible on request.
Topper
Combi 2 TOPPER: For all possible circumstances
The topper can fold-up in two parts, maintaining good visibility for the driver.1 part is 6 rows (3 meter) , and the other is 3 (1,5 meter) While folding,the entire topper slides to the left, positioning the 6 row part in the middle of the machine. After the leaf is cut of by the flails, an auger transports the leaf to the right hand side, where it is dropped onto and spread by a disc-type leaf spreader. The leaf spreader has been increased by about 35%, to handle the extra leaves. Adjusting the scalpers from 18 to 20 inch row-width is done hydraulic.
Cleaning
When we want to lift 9 rows at the same speed as a six row machine,we need to have bigger and additional turbines accordingly.That is why we have 5 big turbines behind the 3 of the lifting unit.
The gates around the turbines are adjustable from the cab, and mounted in rubber silent-blocs for beet-friendly treatment,and less maintenance.
Needless to say, that all the speeds of the turbines are adjustable from the cab as well.
Tank
The ring elevator also been extended. The width is now 90 cm instead of 80 and the depth of the baskets has also increased, thus giving 50% more capacity.
Tank capacity is 25 tonnes.The discharge elevator is situated behind the front wheels making it possible to lower the tank floor about 30 cm compared to other systems, effectively lowering the centre of gravity.
The discharge elevator is 1,70 m wide and unloads the entire tank in approximately 40 seconds.
Drive
This is something special:
Because of the working width of 4,5 meter, we can use the same area to drive on. We accomplished this by extending the front wheels each by 50 cm. Consequently the machine drives one wheel per track.
Also the stability of the machine is greatly improved with the wide front axle.
For those who don't favour full land coverage; it is also possible to lift with the front axle kept narrow, leaving about 1 meter of ground un-touched.
All 4 front wheels are mounted on hydraulic cylinders,which are coupled so their weight is spread 50-50. Also it makes the wheels follow the surface perfectly.
It is possible to lift the machine up 10 cm should the machine get stuck ,or lower it 10 cm for low bridges etc.
All 6 wheels are driven and steered ,which gives a short turning circle of only 8 meter, despite of its size.
The new Michelin radial tyres are 800-70 x 38 and have a 2,10 m. diameter.
There are other wide tyre options, because of the wide working width.
