IMPORTANT NOTE:
The required (hydraulic) power depends on the working depth, soil
conditions, working speed etc. The condition of the triplex greensmower
and the ambient temperature determine the available capacity. Everybody
should check the greensmower during work if it isn’t overloaded by
checking the heat built up and take the correct measurements.
MAREDO DOES NOT TAKE ANY LIABILITY FOR
GREENSMOWER DAMAGES.
Note:
For a safe operation it is essential, that the operator reads and
understands the manual of the Maredo head and the triplex
machine.

TIPS/ REMARKS.
1. Clean the unit regularly with air or low pressurized water. DON’T USE
HIGH PRESSURIZED WATER. The water can enter the bearings causing them to
seize.
2. Use the trolleys to move the heads easily to the triplex. Next connect the
head to your triplex. In some cases, you need to raise the head and remove the
trolley, before you can mount the hydraulic motor.
3. Be careful with tightening the hydraulic motor bolts. Do it evenly and do
not over tighten. The ears of the hydraulic motor may crack.
4. Raise the heads and see if they stay in the right position and does not hit
anything. If it does, make some adjustments till if fits well.
5. Be sure that the heads do have enough ground clearance. Otherwise the
shoes can hit the ground during transport, causing them to damage.
6. Make your first test run outside the green. Play with the engine throttle and
the driving speed. Continue till you are satisfied.
7. Be sure that the hydraulic motor speed setting of the triplex is set at its
maximum.
8. Be careful with dropping the units on a hard (concrete) floor. Put
something (trolley or rubber carpet) underneath to protect the shoe plates against
damages. Damage to the heads may also occur.
9. Check bolts and nuts regularly. Re-tighten if necessary.
10. The optimum forward driving speed is 2,5- 3.0 kmh. At this speed the shoes
push vertically down and enrol themselves along the surface. If you go faster or
slower, the shoe plates may slide along the surface (isn’t a problem, but it is better
to prevent).
11. START AND STOP PROCEDURE: Set the engine throttle at appr. 80%. Drop
the heads on the green and move forwards. Increase throttle till 100% of max revs.
At the end of the pass raise the heads fully.
12. You can make curves with the heads during work, BUT DO NOT MAKE TIGHT
CURVES. Damages to the units and green may appear.
13. CHECK THE (HYDRAULIC) DRIVE OF THE GREENSMOWER REGULARLY.
DO NOT OVERHEAT THE (HYDRAULIC) DRIVE. MAREDO IS NOT
RESPONSIBLE FOR DAMAGES TO THE GREENSMOWER.

FIRST SETUP:
The heads are standard delivered with the motor connection at the Right-Hand side.
We can easily change this to a Left Side drive by removing the clutch parts and
mount them to the other side of the machine (swop the side weights at the same
time). Make sure you mount them in exact the same position as before (do not
mirror them), see picture.
Just easily change the
parts from Right to Left
This point should always face towards the front side
Next, we need a parts kit to mount the head to your triplex greensmower. Maredo
has several kits available. Each kit comes with its own mounting instructions and
partslist.
MAINTENANCE.
CHECK BOLTS
AND NUTS REGULARLY
