strip road and the working path, so it protects sensitive ground and the remain-
ing stands. Timber can be processed at the stump, significantly raising the pro-
ductivity of timber harvesting.
The machine is equipped with a harvester head. It is a multipurpose device
with a chain saw and three hydraulically operated delimbing knives. The har-
vester head cuts tree up to 560 mm in diameter.
The loglift hydraulic crane is the workhorse of the harvester. Its reach is 10.3
m. The crane is operated with joystick controls helping to reduce operator's
strain. The crane and harvester head do the work of the harvester.
The harvester gets its power from a Perkins turbocharged six cylinder diesel
engine, 206 h.p. The engine can run on biofuels which reduce hazardous emis-
sions, and the engine noise level is low.
The Timberjack 1270 В cab has Orbitrol steering and Total Machine Control
System (TMS). With the help of this system many highly automated machine
functions are possible including automatic sawblade control, pressure adjust-
ment of the delimbing knives and harvester tilt-up. All this features mean less
work for the operator. While the machine optimizes wood usage, operators can
concentrate on their main job-monitoring timber quality.
Information is displayed on a large screen with instructions given in clear graphic
symbols and texts.
The Timberjack cab meets all forest machine safety standards (ROPS, FOPS).
All controls are easy to reach, and visibility over the entire working site is excel-
lent. For work after dark, powerful halogen working lights illuminate a wide
area.
A new bogie, wide tires and hydraulic transmission provide a good stability
and high ground clearance. So the Timberjack 1270 В can work in the toughest
harvesting conditions.
