Hydraulic turntable is controlled with a special hydraulic motor (Fig. 50), which is powered
directly from the tractor's hydraulics. For this purpose:
connect two hydraulic push-in fittings to the tractor's hydraulics,
❑
moving an appropriate control lever for distributor in the tractor, rotate the mowing head and
❑
set it in the desired position,
if the head rotation is performed too fast, throttle the oil flow with throttle valves (3) located
❑
just behind hydraulic push-in fittings.
For heads LAMA 120/140 and LAMA 121/141 head suspension can be fitted. If fitting for
LAMA 121/141 is used, it is necessary to use suspension mounting. Head suspension facilitates the
operator's work as he doesn't need to constantly control the extension arm because of the suspension
which enables the mowing head to follow ground vertically within 260 mm, and also enables driving
speed increase while mowing. The suspension has 2 springs providing the head relief which enables
the head to tackle ground unevenness more smoothly. Head relief is adjustable according to the ground
configuration and the operator's preferences. For transport, suspension is fitted with locking pin which
locks the mechanism against uncontrolled motions.
