RA 4400 R : the manure is turned and mixed at the first run, at about 500m³/h to reach 1500m³ at the second run.   Characteristics RA 4000 R rotor Ø 1,10 m Power take off 1000 tr/min Electric control inside run width 4,00 m inside run length 1,85 m Overall width 7,15 m Overall length 2,55 m Overall height 2,10 m 4 wheel drive Swivelling coupling and gear box Transmission with cam limiter Adjustable hydraulical working height Driving speed 45L/mn 0 à 0,5 km/h Weight 4 460 kg Tractor's power 100 à 120 CV Overall length 7,75 m Overall width 2,55 m Coupling on fixed drawbar and 2 free wheels Drawbar with hydraulical suspension Slurry injectors Counter     Standard Option   Advantages of the compost - Reduce manure volume till 50%, leading an important reduction of the spreading costs - Deodorized manure - Quick transformation of the manure's compostion (more precise and homogen spreading adapted to widths) - Use of the compost on corn or grass fields - Concentration of mineral material - No effect on the starting of crops (no phytotoxicity and no "holy ground") - A technic without overcosts compared with the traditional method (a saving of time and money) - Destruction of the wild weeds   To make good compost (example : cattle manure) - Strawing : about 6/7kg/day/animal minimum. - After the turning, the temperature must reach 60°. - The second run has to be made when the temperature decreases to less than 50°, so 8 to 10 days after the first run. - Usually, for an agricol use, two runs are sufficient and you get your compost 40 days after the first run. - A good strawing will guarantee your good results.
