M6800 HD 68HP Diesel 4WD w/Loader
8F/8R FULLY-SYNCHRONIZED MAIN AND SHUTTLE TRANSMISSION
Shifting between forward and reverse can now be achieved smoothly and
quickly, and without needing to stop the tractor. The synchronized four
speeds of the main shift in combination with Hi/Low range allow 8F/8R
speeds. The four speeds permit convenient, on-the-fly up and down
shifting. The optional creep speed kit makes it 12F/12R. (M4800SU and
M4900SUD have 8F/4R.)
E-TVCS ENGINE
The M-Series from Kubota features the E-TVCS engine, a sophisticated
indirect injection, liquid-cooled diesel engine which meets EPA
regulations concerning emissions. Our multi-valve system on
M6800/8200/9000 provides for more efficient air intake, which leads to
greater power, higher torque rise, faster combustion, cleaner
emissions, and lower noise.
HIGH TORQUE RISE
The governor and fuel injection pumps are integrated into a single,
compact unit to produce an astounding 28% torque rise (26% on
M4900/5700). Response to sudden load fluctuations is quick, reducing
engine rpm drop. This means these tractors will perform smoothly under
virtually any load condition with less need for downshifting and
greater fuel efficiency.
BEVEL GEAR 4WD
Thanks to Kubota's bevel gear 4WD system, the turning radius is
comparable to that of a 2WD. As well as allowing exceptional mobility
in tight areas, the bevel gear system allows smooth power transfer to
the wheels at all angles. All gears are hermetically sealed in oil to
improve durability.
HYDROSTATIC POWER STEERING
Kubota's hydrostatic power steering, while assuming the burden of heavy
work, provides smooth, responsive steering. Power assist is enough even
when the vehicle is stationary.
CLUTCH
Kubota has upgraded the heavy-duty main clutch with a new, well-tested
material of superb abrasion resistance to extend clutch life. The
reliability of the clutch for heavy loader work has been further
improved. The clutch diameter is 10.8 inches (275mm) on
M4900/5700/6800, and 11.8 inches (300mm) on M8200/9000.
ENCLOSED MUFFLER
For added operator visibility and even further noise reduction, the
muffler is contained within the engine compartment. The only protrusion
is an exhaust pipe, which can be detached easily without opening the
hood when the ROPS is folded down temporarily. For a lower profile, an
optional under muffler or a down exhaust pipe (on ROPS models) is
available.
AUXILIARY REMOTE HYDRAULIC VALVES
The M-Series have a double-acting remote hydraulic valve with detents
and self-canceling feature as standard equipment. Additional
self-canceling or float type valves are optional. Thanks to the
optional flow control valve (on specific models), the 3-point hitch and
a remote valve may be operated simultaneously. Simultaneous operation
can be made between two remote valves, as well. (Valves are optional on
M4800 and M4900SUD.)
LIVE-INDEPENDENT, HYDRAULIC PTO
The M-Series offers smooth operation with a live, independent, 540-rpm
PTO with a hydraulically actuated, wet-type PTO clutch. Self-modulating
engagement with a light touch means implements engage smoothly. The
independent-type PTO clutch can be engaged or disengaged without
depressing the clutch pedal, regardless of whether the tractor is
stationary or moving. The clutch lever is located on the right-hand
side to provide easy visibility to implements during operation.
3-POINT HITCH
The Category I & II (M4900/5700/6800) and Category II (M8200/9000)
3-point hitch provides fast attachment of implements. The lift rod and
stabilizers allow easy implement hook-up. The telescopic lower link
ends further facilitate attachment (optional on M4800SU and M4900SUD).
Lift capacity is as much as 3310 lbs. (1500kg) on M4900/5700/6800 and
4630 lbs. (2100kg) on M8200/9000 at 24" behind the lift point.
