HITCH THE ARROW SHAFT TO THE PTO
HITCH
IMPORTANT: Keep the hitch streaks and the
strength axis clean, without paint or dirt.
To hitch the power line, connect the universal joint of
the rear telescopic hitch (A) to the PTO (B), pressing the
pin and then release it.
To hitch the arrow shaft to the arrow drive pulley, slide
the u-joint into to the arrow motor pulley and tight the
cradle with the oppressors.
ATTENTION
: After the mill has been connected
correctly to the PTO and to the arrow motor pulley,
replace the protective covers back, including the main
one, just in case it was removed during the tractor PTO
connection.
HOW TO UNHOOK THE ARROW SHFAT FROM THE PTO
IMPORTANT
: Keep the PTO & front axle hitch scoring
marks clean without paint or dust.
ATTENTION
: Follow the shaft bar unhook
process securely as described below.
1. - Turn off the tractor engine.
2. - Press the bolt and pull back to remove the shaft
arrow from the tractor’s PTO.
ARROW SHAFT OPERATING ANGLE
IMPORTANT: The arrow shaft optimum and normal
operating angle will depend on the tractor type and
the pulling bar height from the ground.
For the arrow shaft to work in a normal operating angle,
it must form an angle (C) less than or equal to 15
o
with
respect to the PTO horizontal.
The gear ratio between the pulleys is 6 to 1, that is, as
the tractor delivers 540 rpm at the PTO output, then
the rotor pulley (small) rotates at 3200 rpm. If you use
a tractor that delivers more than 540 rpm at the PTO
output then the rotor would rotate at more than 3200
rpm, this may cause an accident and serious damage to
the Mill. This restriction also applies to the MMIB20 mill.
ATTENTION
: Never operate the hammer mill
with a tractor that offers more than 540 RPM PTO
output, since the hammer mill is designed to operate
under these conditions.
