• The falling danger of the tractor can be reduced by
winching through the lower snatchblock.
Fig. 5.
Fig. 6. Do not winch sideways at angles exceeding
30 degrees. The tractor can tilt.
Fig. 7. Use a snatchblock to avoid winching sideways.
PRE-OPERATION CHECKS
MOUNTING AND USE OF THE LOWER
SNATCHBLOCK
• Usually the logs are winched in through the upper
pulley of the winch. This lifts the logs and they dig
less into the ground. The weight of the load also
pushes the blade into the ground thus anchoring
the winch and the tractor to the ground.
• The winch has a lower snatchblock. The main use
of the lower snatchblock is to lower the pulling
point. This enables larger loads to be skidded out
. For skidding out the load the cable is transferred
to the lower snatchblock.
• Several logs can be hooked up and winched in at
one time by means of keyhole sliders on the cable.
The skidding chain should have a pin on the end,
which makes it easier to pass the chain underne-
ath the tree. See fig. 8.
When using the lower snatch
block make sure that it follows
the direction of the cable. Ot-
herwise the cable will be dama-
ged, when it is pressed between
the snatch block and the lower
snatchblock frame.
When wInching an unloaded
cable, make sure that the finger
guard doesn’t rise up with cable
and doesn’t cause cable to cross-
cut.
Fig. 8. Use a keyhole sliders to winch several logs at one
time.
