Rubber feed scraper on the rear (RVSA)
The feed alley scraper on the back is, like the other Kemp feeders, capable of swivelling 70 degrees, left and right. Because the slide swings 70 degrees, the feed can be slide well towards the cows and it will not start to accumulate. In addition, it is important that the feed is placed next to the vehicle, so that the vehicle does not drive over the feed. Therefore, it is important that the scraper can pivot. Pivoting 70 degrees is possible through the use of two hydraulically driven cylinders. The second advantage of these two cylinders is that there is more power to pivot the scraper during feeding.
The next advantage of the Kemp feed scrapers is that they can oscillate. This means that the rubber strip can move with respect to the mounting frame. The advantage is a good ground adaptation and uniform wear of the rubber.
It is important that the feed is pushed next to the vehicle. The slider is thus available in several sizes, so that there is a suitable scraper for every vehicle.
The core task of the feed sliders is of course the feeding of feed, however, the slide can also be used as a mud slide, snow blade, to slide away any residual feed or to push the sand away on the silage pit.
The RVSA is suitable as a feed scraper on the rear of the tractor. Thus, the feed slider is supplied with Cat. 2 attachment parts.
The RVSA can be supplied with four different rubber strips. The sizes of these rubber strips are 2.800*400*40 / 2.800*500*50 / 3.200*400*40 / 3.200*500*50. The advantage of the rubbers that are 500 mm high is that two rows of holes are drilled in these rubbers. This allows you to turn over or lower the rubber when one side is worn.

Adjustable angles (manually): The feed scrapers are standard equipped with a straight beam, however it is also possible to choose for manually adjustable angles. These angles can be adjusted 35 degrees with respect to the beam. The adjustable angles give you more control to keep the feed near the rubber and thus slide away in the direction of travel.
Hydraulic adjustable angles: When the angles can be hydraulically operated, it is possible to adjust the angles during feeding/sliding. When the corners are in the 35 degree position, a large amount of feed can be moved and when you fold the corners in, it can be pulled in properly.
When choosing hydraulically adjustable angles, two hydraulic functions must be operated. If the vehicle has one double-acting valve, you can choose with a 6/2 control slide from the driver's seat which function is to be operated.
The second option is a 3-way ball valve, which allows you to manually select which function to operate.
Shock valve: a shock valve is needed with vehicles above 4,000 kg. The shock valve provides protection when the scraper collides with something. In this case, the shock valve ensures that the oil from the cylinder, which has come under pressure, is moved to the other cylinder. As a result, the scraper swings past the obstacle and the chance of damage is reduced. The shock valve is of course only possible with two cylinder scrapers.
Throttling, to control the speed of pivoting. This gives you more control when hydraulically slewing the scraper.
