Product description

Mobile and cost effective scale for tractor three-point hydraulic systems

This specially designed, mobile and inexpensive scale turns every tractor three-point linkage into a 6000 kg scale. The AGRETO three-point scale is simply mounted between tractor three-point linkage and implement.

Easy to attach to various implements

Implements seldom conform to category II dimensions, but the AGRETO three-point scale can be used everywhere nonetheless, thanks to the infinite adjustability of the length of the lower link (85-90 cm) and the height between lower link and top link (48-68 cm).

Certainty with regards to input and output

Continuous information on quantities entering and leaving the vehicle enables the correction of erroneous settings.

Cost savings on resources

You only distribute the needed amounts and thus prevent overdosage.

Highest possible transport and operation security

Even when in an exceptional situation a load cell breaks, the construction of the AGRETO three-point scale prevents the loss of your implement and the enormous damages involved.

How does the AGRETO three-point scale function?
The AGRETO three-point scale is mounted between tractor and implement. The implement hangs on the weighing triangle and is weighed.
Which implements can be attached to the AGRETO three-point scale?
In principle every Category II implement with a total maximum weight of 6000 kg can be mounted and weighed. The three-point scale is mostly used for weighing fertilizer spreaders, but also for transport crates, feed mixers and similar implements.
Which implements can't be attached?
Implements with attachment parts near the scale can't be attached (for instance, fertilizer spreader output adjusters).
How are implements attached that do not fully conform to Category II?
In practice, mounting dimensions very often deviate from the Category II standard. For this reason the AGRETO three-point scale can be adjusted horizontally and vertically to fit the implements.
Can the three-point scale be attached to Category III tractor hooks?
Yes, but only when Category II pins are used on the three-point scale. For this you need reduction balls from Category III (outer diameter) to Category II (pin diameter). There is more than enough space for the hook.
How are implements with rigid axles attached to the AGRETO three-point scale?
One side of the weighing triangle is pulled out, threaded to the shaft and pushed back in place. If changes are made frequently, we recommend the accessory equipment with a hook at the rear of the scale. These are to be ordered immediately.
How big is the offset to the back using the AGRETO three-point-scale?
Due to the ccompact design of the tree-point-scale, the offset to the back in the standard version is only 16 cm.
If the additional 13 cm shorter top link pins are used for the top link, the attachments only move about 14,5 cm backwards.
The offset to the back using the Walterscheid quick compling-hook is 20 cm.
Can the AGRETO three-point be used for sowing machines?
A three-point scale should in principle not be charged with high horizontal forces. A seed drill is not a problem, but a sowing machine that works the soil as well shouldn't be attached. Monitoring the content of a seed tank with a small amount of seeds (for instance, rapeseed) is not possible, as the scale's resolution is too coarse.
Why must the distance between the weighing triangle's lower link pin and top link pin correspond to the distance on the attachment?
When both heights correspond, there's a right angle between scale and upper mounting bracket. Only when this right angle is exactly 90°, does the scale measure weights correctly, no matter the position of the load.
How does one set this right angle?
There are 4 holes with a distance of 47.5 mm for attaching the upper mounting brackets. This allows for a rough adjustment. The mounting elements with the 4 holes can be infinitely adjusted through slits with a mounting range of 50 mm, until a right angle is achieved.
Does the AGRETO three-point scale have to be exactly vertical?
It would be ideal, but for many attachments the top link's mounting point sticks out further than the mounting points of the lower links. This makes a slanted position for the scale inevitable. The slant can be partially compensated by using the shorter top link brackets with 130 mm pin distance. However, a slight slant doesn't really impact weighing accuracy all that much. If necessary, calibration of the weighing indicator can be adjusted to the slanted position. The right angle between scale and top link bracket must be maintained though.
How accurately does the AGRETO three-point scale weigh?
The weighing indicator's resolution is set at 5 kg. In practice, this accuracy can be achieved with a properly set up scale as well.
Can the weighing indicator be read while driving?
Yes, the AGRETO three-point scale's weighing indicator has been set up in such a way that it shows stabilised values.
Can the AGRETO three-point scale be washed?
Yes, it can. In fact, this needs to be done regularly when used in combination with fertilizer spreaders. The scale is waterproof according to protection class IP68 and the load cells are on the inside.
How does the AGRETO three-point scale react to shocks?
The special construction for load introduction doesn't allow a lot of torque to be applied directly to the load cells. Moreover, a nominal load of 2 x 5000 kg and breaking load of 2 x 10,000 kg keeps them on the safe side.
