The SCHOUTEN Rabbit R1825 is a pre-construction scarifier for the sweeper Phoenix PX1802. The mounting points for this are welded to the frame of the sweepers as standard and the drive unit is equipped with an additional output with which the scarifier unit can be driven. By mounting the scarifier unit directly on the sweeper, the machine can be used more widely and can be varnished and swept in 1 pass. The working depth is infinitely adjustable in height. Due to the fixed starblades an intensive and effective operation realized. Quick and easy assembly and dismantling, without the use of tools, make the Rabbit in combination with the Phoenix PX1802 a multifunctional machine.
