2.0 Summary
All the subsoilers feature a strong V shaped frame which lets soil and trash flow more efficiently,
allowing the legs to be run closer together giving total loosening. This aggressive action increases the
aeration, leaving a surface 50 - 100mm raised up. The Sumo range of Subsoilers can be used successfully
as a primary and a secondary source of cultivation, leaving the surface weather proof and ready to drill.
Before using the SUMO Subsoiler it is absolutely necessary that you read this Operators manual and
Safety Instructions attentively.
Specifications, descriptions and illustrations in this brochure are accurate, as known, at the time of
publication but may be subject to change.

Model:
Mounted Subsoiler
Date assessment written:
16th February 2012
Year:
2012
Assessor:
R. A. Hight
Purpose of machine:
Primarily designed to alleviate compaction and improve soil structure in an agricultural environment.
Notes:
Ensure the
operator manual is
read and fully
understood.
Description of machine:
A three-point-linkage mounted farm implement consisting of 2 major elements.
1. A bank of staggered subsoiler legs.
2. A rigid packer roller
All of the above is arranged in a heavy duty fabricated steel framework.
The Machine is designed to couple to a suitably powered tractor.
3.4 RISK ASSESSMENT

4.0 Operation and Adjustment
4.1 Operating
Before attaching a subsoiler to a tractor is essential that the stands are in the down position to ensure a
short top link once attached. Once attached securely to the tractor the machine can then be raised and the
stands lifted out of the way. When the machine is removed from the tractor it is equally as important to
leave the machine on the stands.
Due to the physical nature and weight distribution of the Sumo Subsoiler a category three enclosed ball
top link is highly recommended as the best option for dealing with the exaggerated loads experienced
during normal working conditions.
The top link should be as short as possible whilst remaining as close to horizontal as is achievable. In the
majority of cases this means using the bottom hole on the Subsoiler and the top hole on the tractor. It is
important to ensure the machine is running level to allow the optimum level of soil disturbance as well as
to prolong the life of the wearing parts.
Changing the points on the Subsoiler must only be done on level ground. When it is deemed necessary to
change the points, the stands should be lowered to the static position and other appropriate jacks, stands
and chocks put into position in sensible locations. To avoid the risk of sinking and potential injury it is
important to only change the points where ground conditions permit, i.e. solid concrete, tarmac etc. Care
should be taken to ensure the subsoiler is firmly and safely held before changing the points. The tractor
engine must be turned off with the parking brake applied. In order to change the points it is first necessary
to remove the nut and bolt behind the point freeing the worn part. Then a new point can be replaced in the
same position, with the appropriate nut and bolt tightened up to secure the point in position.
Bearings should be greased (see 5.0 Maintenance), stands must be in the raised position and all relevant
pins in the correct holes prior to commencing work.
Forward working speed should be governed by the local conditions as well as the finish produced by the
Subsoiler.
4.2 Adjustments
Depth adjustment of the subsoiler legs is achieved by altering the height at which the packer is set and a
combination of the top link length and lower linkage height. The machine should always remain level in
when working. The lower packer pin must be placed in the upper-most hole under the packer arm to
prevent the arms chasing and wearing in the slots every time the machine is raised. Failure to do this can
result in excessive wear to the packer arms, main side plates and the quadrants.
DO NOT TIGHTEN POINTS UP WITH AIR RACHETS OR OVER TIGHTEN WITH
SPANNERS. EXCESSIVE TIGHTENING WILL RESULT IN POINTS CRACKING

4.3 Auto Reset hydraulic circuit
1) To lift the legs up and out of the work position; pressurize line B (the lower of the two hoses
entering the valve block & marked “B” on the valve itself). The legs will lift as oil is returned to
the tractor through Line A.
2) To lower the legs back down and into the work position; pressurize line A, the legs will lower one
by one. Keep pumping until all of the legs come to a stop at the end of their stroke. Keep
pumping for a few more seconds and the two lines will then pressure up. Keep an eye on the
gauge on the right hand side of the machine as this displays the leg trip resistant pressure. The
system needs then to be put into the “float” or pressureless state between the tractor and the valve
so that any back pressure from the tractor does not affect the preset valve pressures. Putting the
system into “float” means the factory set pressure readings of 80bar on the full bore side of the
ram (gauge on RHS of machine) and 20bar on the rod side of the ram. This is unless of course
they have been adjusted to suit local conditions. The resistant pressure in adjustable up to a
maximum of 150bar
3) To increase the trip resistance of the legs –the knob marked X should be wound in. The lift and
lower process should then be repeated.

5.0 Maintenance
The packer bearings should be greased with one pump once a week and after washing off.
The condition of the subsoiler legs and the points should be regularly monitored in order to maintain the
most efficient use of the machine.
Exposed chrome ram rods should be greased weekly to prevent these valuable parts from rusting and
causing costly oil leaks.
The condition and position of the packer scrapers should also be observed in order to prevent soil
building up on the packer. Ensure the scrapers are not touching the packer though, as this will add rolling
resistance as well as causing premature wear of the packer.
5.1 Spares
When ordering replacement parts please have your serial number, part numbers (listed in Section 6.0) and
quantities at hand.
5.2 Winter storage
When machines are to be parked up for the winter period, correct storage techniques are an important part
of protecting the machine to ensuring a hassle free season. When the machine has finished work it should
be cleaned down and washed off to remove all traces of soil.
Following washing of the packer bearings should be greased with one pump. Other grease points on auto
reset machines are located on both ends of all rams and auto reset pivot hinge bushes; these should
receive two or three pumps of grease.
Exposed chrome ram rods should be greased to prevent these valuable parts from rusting over winter and
causing costly oil leaks.
When the machine is parked up a note should be made of what wearing parts require replacing ready for
the next seasons work. The wearing parts can then be ordered in time ready for the next season’s work in
good time to avoid delays when the machine is required earlier than expected!
