Rotary Tiller RXT, BXV & CXT Series
Working Depth Adjustment
The working depth is controlled by raising or lowering the side skids. If the skids are raised, the working depth
increases. By lowering the skids, the tilling depth with decrease.
Tailgate adjustment
Position the tailgate to its desired opening by fitting the bolts into the appropriate holes of the adjustment
flange located on the top of the main frame. To adjust the degree of tension, tighten or loosen up on the 24mm
nut on the top of the spring support rod.
Multi-Speed Gearbox
On certain models, the tiller will come standard with a multi-speed gearbox to allow rotor speed changes. This
is particularly useful on uneven ground so as the tractor speed can maintain a constant ground speed and rotor
speed to adapt to different soil conditions.
To change the rotor speed, do the following:
1. Ensure the gearbox is not too hot to work safely without burning your hands.
2. Tilt the tiller forward to prevent excessive oil from coming out of the back cover.
3. Unscrew the bolt holding the rear cover of the gearbox.
4. Adjust the gears inside the gearbox to obtain the desired speed.
5. Replace cover and tighten bolts.
IMPORTANT: Make sure the spacers located behind the gears do not fall
into the gearbox! If this happens damage to the gearbox or gears can occur.
