Bottom drive disc mowers are applied in mowing all green crops designated for direct feeding, hay or silage. The SIPMA KD 2400 PRERIA model is equipped with a conditioner.
The bottom drive design ensures even distribution of material over the entire width of the swath, which contributes to uniform drying of the cut grass, and allows direct harvest with a baler (by eliminating tedding and raking).
6 discs rotating at a speed of 3200 rpm provide high cutting quality and performance (compared to top-drive mowers) to 2,5 ha/h.
A control system with the use of the member connecting coupling frame upper point and the tractor’s three point linkage allows setting an appropriate angle and cutting height from 30 to 80 mm, which has a huge impact on the grass re-growth rate.
A swath ripper is recommended for high grass and allows laying airy swath and shortening the time for silage drying by 20-30%.
A hydraulic cylinder powered by the tractor’s external hydraulic system allows to raise the cutting unit into the transport position, which facilitates the work and enhances its comfort.
Mouldboards mounted behind the cutterbar allow for adjustment of the swath width within 60-90% of the
Swath opener beaters are made of a „V” shaped plastic. They are very effective and cause minimal material loss. Settings of the thrashing floor (working slots: 3 frontal and 2 rear) give a combination of 6 crushing degrees of the mowed material.
Elastomer safety catches allow tilting the mower bar backwards if hitting an obstacle, thus protecting the machine against damage.
Grinded gear wheels reduce noise and ensure long and trouble-free operation.
The SIPMA PTO drive shaft equipped with a one-way clutch – for smooth stopping and protection of the discs’ drives from damage.
