the working of particular mechanisms, their regulation and proper adjustment.
2- Before and while working it is recommended to NOT have any alcoholic drink,
medicine or other, which could alter physical and mental capabilities.
3- Before getting to work, the digger and the tractor efficiency should be checked out.
Before setting the digger in motion, it should be also checked if there is any people
around.
4- Speed should be adequately limited and precautions taken while turning and going
up.
5- Soon after having finished the work and during breaks, the digger should be
lowered to the ground and detached from the tractor.
6- Connection to the tractor should be done with extreme caution.
7- Repairs, regulations, cleaning, maintenance, technological disturbances removal
ought to be made with the digger and the tractor NOT connected.
Most of the accidents at work are due to non-observance of the basic
precautions of safety.
Many accidents happen while moving the group tractor-machine on the road
and in the farm.
It is forbidden:
To use the digger without having read this handbook attentively.
To lubricate, adjust or repair the digger while it is connected to the tractor.
To use the digger or a tractor which are not efficient.

To allow unauthorised people to use the digger.
To make sudden turns.
To transport people.
To leave the digger in the transport or working position.
To work on slopes without proper precautions.
Every time the group tractor-machine has to be moved, it is necessary to
comply with the rules of the Highway Code.

2.3 Target of the machine
The potato digger KMC has been projected to dig one, two or more rows of potatoes
(depending on model and working width) and to unload products to the ground in a
central windrow.
It is forbidden to modify the machine or parts of it, addressing it to a use
which is different from the foreseen and here specified one.
The machine must be connected to the 3-points hitch of the tractor, and gets its
movements from the tractor PTO, through the cardan shaft.
Any other connection is considered unauthorised.
2.4 Functioning
Thanks to its features it can be used to dig both early and ready products.
The front digging part is made of 70/80/90 “V” shaped opening shoes (according to
the model) and 2 disks for cutting grass.
After being dug, the product is cleaned from exceeding soil on the main web and then
unloaded to the ground at the rear part of the machine in a central windrow.
The web is placed on rollers and supports, and it is equipped with triangular shakers
that help cleaning potatoes from soil.
The web is moved by means of two driving belts, protected by a plate fasten to the
frame.
The implement can be equipped with further cleaning devices: second web or rear
oscillating grid.
2.5 Workers
The machine KMC has been projected to have NO workers on board.
It is so forbidden to people to stand around or on the machine while it is working
(minimum distance=mt. 3).
Staff:
N. 1 Tractor driver. He must be trained and informed on how safely and
meticulously run the group tractor –machine.
N. 1 Qualified technician. He provides the operations of adjustment, repair,
installation and use. He must be qualified, trained and informed in all these
operations.
All the other people are considered unauthorised
2.6 Transport
Thanks to its dimension (see table at paragraph 2.2) the machine KMC can be
transported on trucks, trailers, ….

Only operating staff which has been trained in the use of a forklift, a crane
or any other lifting equipment, is allowed to lift and load the machine.
Hook the 3 lifting points (see table at paragraph 1.2) with a chain or a rope, then lift
the implement
3 INSTALLATION AND USE
All the operation of installation, connection, adjustment,…must be carried on when the
machine and the tractor are not connected.
Never do these operations on slopes and / or hills, or in any other place
which do not assure the complete steadiness of the machine.
Proceed as follows:
wear working gloves, glasses and shoes
follow all safety rules presented in chapter 1 of this handbook.
3.1 Preparation of the digger
The qualified technician, in order to prepare the machine for its first activation,
should:
Make a general overhaul of the implement.
Check tyres’ pressure.
Check web functioning.
Check oil level
Check that all safety devices, removed for transport exigencies, have been
replaced.
3.2 Connection to the tractor: 3-points hitch
Proceed as follows:
Get the tractor close to the machine and lower its lifting arms
Switch off the tractor engine and remove keys
Connect the first and second point to the tractor lifting arms
Connect the third point (Pict. 2, point 2)
Connect the cardan shaft to the tractor PTO (see paragraph 3.3 Cardan shaft).
Pict. 2

After having connected the digger to the tractor, make it running at slow speed.
During this first activation, special attention should be paid to proper working of the
driving elements and the carrying web.
Safe working rules presented in the handbook (chapter 1), should be obeyed
during the first activation of the implement.
ATTENTION !!
Make sure that pins are correctly inserted and locked by snap slip pins.
Tractor must have a PTO running at 540 rpm with a clockwise rotation .
While working the PTO has to be settled at 350 rpm.
The potato digger KMC should not be connected to a PTO rotating at 1000
rpm, otherwise the reducer could be seriously damaged.
3.3 Cardan shaft
The potato digger KMC is supplied to the customer with a cardan shaft and its use and
maintenance handbook.
Before connecting the cardan shaft to the machine and the tractor, carefully
read its use and maintenance handbook.
Check cardan shaft length as soon as you receive the digger and every time you have
to change tractor.
Pict. 3 cardan shaft in closed position
Connection of cardan shaft with snap split pin:
Check that cardan shaft split pins can freely slide. If not, properly clean and
lubricate.
Connect the cardan shaft, first to the digger and then to the tractor.
Check that pin 1 is housed in seat 2 (Pict. 4)
Vigorously pull cardan shaft to make sure it is locked.
Repeat this operation from tractor side.
