Grillo FD1309 4WD Commercial Collection Ride On Mower

For commercial grass collection applications on large sites
Despite its extremely large grass bin the FD1309 is a compact machine. The hydraulic powered 4WD steering system allows a very tight turning radius of only 31 cm! The small wheelbase gives the machine extraordinary manoeuvrability in narrow spaces.

Cutting on steep slopes or transversally across inclined hillsides is helped by excellent weight distribution as well as by automatically or manually activating the differential locking device in conditions of extreme steepness.  The pivoting rear axle allows drive to all 4 wheels even when cutting on uneven ground.  There are no problems with the FD1309 in mounting kerbs or sidewalks as the out-front cutter deck can be hydraulically lifted to get over obstacles. Hydraulics are also used to achieve a step-less cutting height and to lift the grass bin up to a height of two metres for dumping the grass into a truck, if required. 

Hydraulic parts are sourced from the world’s top manufacturers.  FD1309 is fitted with a Yanmar diesel engine model 3TNV82, with 3 cylinders and rated at 31HP.
The engine is liquid cooled with a self-cleaning radiator and the electric fan is able to reverse its rotation in order to remove grass and debris from the radiator. Engagement of this system is automatic and controlled by a sensor, but can also be activated manually.
 
FD1309’s driving position is ergonomic and designed in such a way that the operator will not feel undue fatigue even after long periods of work. The machine has a wide, comfortable and adjustable driving seat which is dampened and fitted with arm-rests. All hydraulic controls for the grass catcher and cutter deck are operated by means of practical electric push-buttons. Acoustic comfort is achieved by an innovative air flow reduction system and by a noise reduced engine. A driver’s comfort cabin with a large view field with heating is an optional extra. The machine is homologated for road use.
Apart from the standard 132cm (52") collection cutter deck other decks are also available: Cutter deck MP 130 cm with three blades and twin functions:  rear discharge or mulching by simply moving a lever, whilst the cutter deck LMP 160 cm with three blades and triple functions: side discharge, rear discharge and mulch.  There is also available an all purpose 135cm flail deck with a blades scarifier kit and a 150 cm hydraulically operated snow blade.

The Grillo FD1309 has a number of unique technical features one of them being the deck chute charge accelerator.  This is not a fan or turbine and therefore operates with significantly less noise.



The charge accelerator is a system involving rotating flails which rotate at a relatively low speed.  The transfer of cut grass up into the bin is not made by a fan or turbine which is susceptible to blockages and high noise levels.  The Grillo charge accelerator provides a low noise, highly efficient means of transferring the grass which reduces the likelihood of blocking.

The efficiency of the charge accelerator also allows cutting in extreme conditions such as long and humid grass which is typical of first Spring mows.  FD1309 is also extremely capable collecting leaves and other debris off the lawn.  The grass catcher is equipped with an oscillating baffle which allows the cut grass to be evenly distributed throughout the bin and this provides complete filling.  Once the grass catcher bin is full, a sensor stops the blades thereby avoiding any blockage of the collection chute.
