9.10 Net tension adjustment
The tension on the net is achieved by means of a variable pulley. The net can be
tensioned from 0 to 7% stretch, depending on the quality of net used and the
percentage dry matter of the material being baled. The machines are pre-set at 2%
stretch. McHale recommend using a lower percentage stretch when baling dry matter
material like hay and straw and a higher percentage stretch for material like grass.
These percentages will vary depending on bale density and type of crop being baled.
The following steps show how to adjust the variable pulley.
CAUTION: Bale size should not exceed 1.27 m in diameter
Always ensure that the bale size does not exceed 1.27 m in diameter.
Bales with a bale size in excess of 1.27 m in diameter may result in
damage to the net.
WARNING: Ensure the tractor is shut down before adjusting
Never adjust the net tension while the baler PTO shaft is engaged or
while the tractor is running. Shut down the tractor, remove the ignition
key, apply the parking brake and prevent any machine movement with
wheel chocks.
1. The variable pulley is the inner one
located closest to the net unit side.
Insert the net-unit handle provided,
into the slot on the spring-loaded belt
tensioner and pull the handle forwards,
until the hook can be swung up to latch
the tensioner bolt temporarily, as
shown. The belt should now be slack,
allowing the variable pulley to be
adjusted, as required.
