Before installation/maintenance, the tractor and attachment should
be stationary with the hydraulic lift system in a neutral position and
the ignition key removed.
On a flat area of ground lower the three point linkage on the tractor to its
lowest position. Attach the attachment to the tractor using the three point
linkage pins and linch pins:
Installation Overview
1.
With the attachment on the ground, adjust the length of the top link
arm so that the attachment is level.
2.
Check the clearance between the attachment skids and the blades for
the tilling depth.
3.
Raise the tilling depth for drier patches of ground or heavier soil
types. To do this, raise the tractor
’
s hydraulic lift arms and adjust the
skids on the attachment to increase the blade tilling depth. A lower
pass can be made when the top layer of soil is broken up.
4.
The working speed of the attachment should be at a walking pace of 1
to 4 mph. Heavier soil should be cultivated at a slow pace for the best
finish and to avoid any damage to the attachment.
5.
Lubricate all grease points including PTO drive shaft. Attach the PTO
drive shaft and ensure locking pin is secure on both the tractor and
attachment sides. Attach the chain to a secure point on the tractor/
attachment.
6.
Ensure all safety guards are in place.
Always replace worn or
damaged
PTO drive shafts.
Operate the attachment with tractor in a
low gear range, keep the PTO output from the tractor at 540 rpm.

Installation Overview (Continued)
•
Check the tractor's 3
-
point hydraulic lift system. It should operate up
and down smoothly and hold its position when set.
•
The tractor should be equipped with stabiliser bars, and adjustable
sway chains or sway blocks to keep the attachment from swinging
side to side.
•
Small tractors may require front counter weights to counter
-
balance
the weight of the attachment. We recommend the tractor has a
Rollover Protection System (ROPS) and a seat belt is used.
Operating Advice
1.
Take extreme care when travelling, slow down on turns and watch out
for uneven land. Always reduce speed on slopes/corners to avoid
tipping.
2.
Check the soil type and moisture level. If the ground is too dry, the
blades will struggle to cut in, and if too wet the soil will
‘
ball up
’
in the
rotor and blades. Typically, sandy soils can be worked better than
heavy clay or loam soil types.
3.
Before starting any work, check for/remove any obstructions such as
buried pipes, rocks and stumps.
4.
Set correct working depth, check the drive chain, belts and blade
condition and the tightness of all bolts, buts and screws.
5.
Check the oil level in the gearbox and chain case.
6.
Begin by slowly easing the rotovator into the soil:
Lower the
rotovator so the blades are just off the ground, then start the PTO
drive from the tractor, slowly increasing to 540 rpm to engage the
blades. Lower the linkage slowly, to allow the blades to cut into the
soil. Move forward in a low gear, and increase speed to suit the
ground conditions. If the tractor/attachment appears to struggle, slow
the speed.
7.
We recommend using two passes when tilling hard or compacted
soils. For consistency and to minimise compaction, make a second
pass at an angle to the first.
8.
Use the rear flap to maintain a level seedbed. Adjust the angle of the
flap if necessary using the chain and brackets.
