Serial no.:
IMPORTANT:
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
For a safe operation it is essential, that the operator reads and
understands the manual of the Maredo machine.

FIRST SETUP:
Unpack the GT424 carefully from steel side panels.
If the drive side needs to be changed to the other side, do NOT remove the main
spike shaft. You can easily exchange the side weights with the complete gearbox,
because the main spike shaft has a tap for the belt pulley at each side.
Carefully take the belt drive apart and built it exactly the same way at the other
side of the head. Same thing for the side weights incl. the bolts/ nuts.
Normally the GT424 is delivered with the right greensmower mounting kit.
We have the following kits available:
TORO Triflex 3150/3250 Jac. Gplex/ Gking JohnDeere
2500B/E

GENERAL TIPS/ REMARKS
1. Do not use the seeder unit in wet conditions. The funnels may clog.
2. You can check the dosing rates yourself. 10.3 revs of the front roller equals 1m²
(or 9.4 revs matches 10 sq ft). Measure the seed amount and you know the dosing
per m² or per 10 sqft.
3. Clean the unit regularly with air or low-pressure water. DO NOT USE HIGH
PRESSURIZED WATER. Use air to clean the seed funnels.
4. Fertilizer can be applied, as long as it can be fed through the dosing roller,
however the zinc plated dosing roller may get hurt. BE CAREFULL and CLEAN WELL.
5. Play with the engine throttle and the forward speed, if the holes do not look
nice. You may even use the heads without the hydraulic motor running (the spikes
just roll over the surface, without vibration).
6. If the holes are not deep enough, slow down on driving speed and/ or increase
the engine rpm’s, so that the vibration per spike increases and a bigger hole is
created.
7. The dosing rate is not only determined by the gear set, but also by the gap
between the dosing roller and (rear) seal plate. See also the dosing decal in the
seed box. The larger the gap, the more seed is sown. Calibrate yourself, if needed.
8. The heads are very heavy and need two persons to carry (with the grip at each
side). However an easy trolley is standard delivered that can be mounted
underneath and which makes it easy to roll the heads under or away from the
greensmower.
9. You can play right after the green has been overseeded.
10. Don’t make tight curves. Straight passes are the best, with a final clean up
pass.
11. Check if the heads are well mounted at your greensmower. If not adjust the
mounting kit. The heads should be floating during work and secured during
transport.
12. If the seed boxes seed at different rates, check & adjust the gearwheel setting
and the gap between the dosing roller and the (rear) seal plates of each individual
head.
13. If your turf is damaged during start-up (as the spikes start spinning), start at
lower engine rpms, outside the green, or drop the heads down with the
greensmower still in transport mode. When at the ground, switch back to the work
mode and engage the drive.
For some Toro model greensmowers, we have an electronic delay relais available
that will help you solving the problem.
14. Be careful when dropping the units on a hard (concrete) floor. PUT SOMETHING
UNDERNEATH TO PROTECT THE SPIKES, PLATES OR ROLLERS. Or just simply use
the trolleys all the time.
15. Check bolts and nuts regularly.

The funnels are mounted against the rear panel of the seed box. You can see from
the top if they are all open. DO THAT REGULARLY. If needed clean the funnels, by
using air. Blow it from the top and from the bottom (by tipping the head).
By changing the two gears behind the R clip, a different dosing is achieved. See the
decal inside the seed box.
Clean the seed box and dosing system, especially when coated seed is used
regularly.

MAINTENANCE.
1) Check nut, bolts and other parts of the machine on a regular base. Check for
damages or loose parts and fix and tighten the eventual errors prior to use.
2) Never use a high pressure water washer to clean the GT424. Using a high
pressure washer will relieve damage the machine and its bearings. Make sure to use
low pressure water or compressed air to clean the machine. Make sure to clean
after every use.
DOSING RATES.
At the decal in the seedbox, you will find the dosing rates of Kentucky and Fescue. If you want
to use another seed or if you want to check the setting, turn the front roller 10.3 rpm and
measure the amount of seed. The weight is the amount of seed per 1 m². If the 3 heads dose
uneven, fine tune via resetting the gap between dosing roller and rear seal plate.
