Technical Details


KDT series of SaMASZ mowers is the most frequently purchased series in our offer. Since the beginning of their introduction to the market KDT mowers have been used by thousands of customers in Poland and in the whole world. During their design we took into consideration the most up-to-date global development trends. Thanks to that, KDT match modern mowers of leading european manufacturers. They are much cheaper in purchase as well as in maintenance, made of the best materials, they are a great alternative even to the most demanding customers.

Since 2011 KDT mowers have been equipped with new Perfect CUT cutterbar. Disc mowers are economical alternative to drum mowers especially on large farms, because they are 20% cheaper in maintenace and are more durable.


2 Mechanical safety breakawaydevice (with hardened inserts)

In case of coming into an immovable obstacle the breakaway device is pulled out and the mower folds backwards giving time to an operator to stop working and evade an obstacle. The force at which the device will operate is regulated by means of a spring, which is set by the manufacturer and ensures proper work. During design of the device hardened insert were used.
3 Larger support springs

They enable decrease of pressure on the ground, which lowers resistance during work
4 Support mechanism when taking turns over swaths.

Owing to this solution an operator does not have to pay attention to the height to which he lifts the machine. It also spares time crucial during forage pick-up.


During transport there are the following protections:

1. Mechanical lock
2. Shut off hydraulic cylinde

Transport and operation

Modern, lighter and hardened suspension as well as hydraulic mechanism facilitate manouvering and transport. Switching from working to transport posi- tion by means of hydraulic mechanism.
1. V-belts – the drive is transmitted through V-belts, which also function as star ratchet clutch.

2. New intersecting axis gear – 60% harder and 200% more durable transmits the drive from V-belts to cutterbar. Replaceable pivot bushings with quick change.

3. Replaceable hardened protecting slide (new) and other sliding skids made of hard-to-tear steel.


Using tine conditioners decreases nutrition loss of the plants and increases thickness of the swath. When mowing caney crops the best effects are reached with roller conditioners.


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.
