3 Basic Information
3.1 Use of the Machine
The rotary hoe is designed for inter-row soil digging and small weeds disposal. It guarantees soft soil softening and its loosening
between the rows of sown crop cultures. It does not turn soil over, it only mixes it. Based on its type of knives used, it is particularly suitable
for lighter soils. The RP-T2/S rotary hoe’s power drive is PJGCV160 or PJGCV190.
It is forbidden to remove any protective devices and covers from the machines.

3.2 Description of the Machine and its Parts
The rotary hoe RP-T2/S (Fig. 2 ) features a few groups:
Gearbox T-2/S (1) - the steering wheel is attached to the front of the gearbox using the pins; a carrier with a skive and hoeing device
cover are attached to the rear side, using the same pins. The hoeing device is mounted to the output shaft through the axial pin. The drive unit
is attached to the flange at the top of the box, and it is secured with quick-release clamps.
The hoeing device (2) with its working widths of 12, 18, 28, and 34 cm with angular knives is an autonomous working component of
the rotary hoe. It consists of 4 regular stars, 2 narrow stars 2 spacers and 2 axial pins. There is no distinction between the left and right stars.
The hoeing device is attached to the gearbox output shaft.
The covers (3) are the machine’s integral parts that must not be removed. They prevent treated soil from hitting the machine operator.
They consist of a cover holder, top cover for the working widths of 12 and 18 cm, top cover for the working widths of 28 and 34 cm, left and
right sides, hinged cover for the working widths of 12 and 18 cm, and hinged cover for the working widths of 28 and 34 cm. The covers are
mounted on the gearbox together with the skive carrier by means of two pins, which are secured with cotters.
The steering wheel (4) is used for moving the machine. It prevents the machine from being buried in very light soil while working.
Together with the skive, it sets the hoeing depth. It is mounted to the front side of the gearbox by means of two pins, which are secured with
cotters.
