Technical Details


KDTC mowers have been the first disc mowers with central suspension in our offer. They have been manufactured since 2008 and have gone thorough modernization in order to be up to present condiitons. Developed and proved design is an economic alternative to KT mowers. They can be equipped interchangeably with tine or roller conditioner.

3 Hydraulic safety breakaway device

KDTC mowers have the same hydraulic safety breakaway device as double-sided mowers. It protects mower against hitting into small obstacles. In the event of hitting an immovable obstacle the cutterbar folds back about 30 degrees and at the same time rises about 70 cm. Afterwards, the cutterbar automatically comes back to its working position.

Transport position and taking turns over swaths

Putting the mower into its transport and working position and taking turns over swaths by means of hydraulic cylinder.
Advantages of use of KDTC mowers

• Equipped with modern Perfect CUT cutterbar
• Mechanical lock when taking turns over swaths
• Regulated speed of cutting unit lowering
• Regulated swath guides
• Central suspension enables even weight balance on the ground and perfect ground following
• Wide range of inclination (up to 24 degrees) enables operation on uneven or steep terrain


Drive from central gearbox to cutterbar's intersecting axis gear is done through PTO shaft with friction clutch, which protects the cutterbar against any damage.

Automatic evasion of the obstacles


Basing on the experience of our customers in Poland and in Western Europe we have introduced to our production a new model of cutterbar: Perfect CUT. Precise cut, high durability of components, protection against sudden disc stop in case of coming into an obstacle, quick and easy disc module replacement owing to modernized upper disc hub are the main advantages of Perfect CUT cutterbars. New cutterbar is mounted in every SaMASZ disc mower apart from KDL series based on Comer cutterbar.
Main advantages of PerfectCUT cutterbar:
1. Smooth regulation of cutting height from 4 to 7 cm.- sliding skids from 5 to 9 cm
2. 6307 2RSN bearings in bevel gears and 6307 2RS in disc modules are the most durable and unprecedented among our european competion.
3. Specially hardened discs and sliding skids made of Boron steel, protected against mud and dirt by means of the blades.
4. Easily replaceable knife holder pins.
5. Hardened knife holder made of Boron steel, especially designed in order to eliminate stucking of the knives under the disc.
6. Innovative system of quick knife replacement. The knife can be changed only when the disc is adjusted sheer to the cutterbar (+ - 30 degrees). The system decreases the probability of knife loss almost to absolute minimum in case of hitting into stone.
7. Modernized, hardened sliding skids made of Boron steel protect the whole surface of cutterbar on the bottom. Quick and easy replacement of the skids (only two bolts to unscrew).
8. Additional steel skid protecting cutterbar's drive.
9. Hardened cutterbar made of steel.
10. Protection against stones in standard equipment.
11. Quick and easy replacement of disc module thanks to modernized upper hub.
12. Bevel gears with 25 mm tightness.
13. High quality knives comply with strict safety rules. SaMASZ logo engraved on the knife is a guarantee of its quality.


1 Protection against stones in standard equipment

Specially designed disc module protects the cutterbar with bevel gears in case of very strong, extreme hit of the disc e.g in a stone. The force of the hit cuts off only the key. Then, only the module needs to be replaced without the necessity of expensive cutterbar repair. The replacement of the module takes only a while and can be done on the field. Owing to that solution the time crucial during forage pick-up is spared. Modernized upper disc hub enables quick module replacement. Special cavities for bolts make it very easy to disssemble the module without the necessity of unscrewing upper hub. The drive of the discs is transmitted by means of bevel gears with high diameter, which increases the resistance of the disc in case of hitting into an immovable obstacle.


2 Comparison of bevel gears
Our mowers are equipped with Perfect CUT cutterbars based on bevel gears transmitting higher strength.
5 Perfect quality of cut with Perfect CUT cutterbar
New Perfect Cut cutterbars have high quality of cutting even with very low grass during 3, 4 and further cuts. During 1 and 2 cut when high grass prevails it is recommended to cut with height between 53 mm and 68 mm. Depending on the angle of cutterbar's inclination there are the following cutting heights.
3 Perfectly profiled design
Rounded shapes of cutterbar's bottom surpass the designs of other manufacturers. Streamline shape facilitates operation on more earthen and stoney meadows. No sharp edges on the whole cutterbar, smooth surfaces of sliding skids give protection to the turf.
Quick knife replacement by means of special key.
