Operation
The Model 854 Trac-Vac is designed to operate at a 540 RPM PTO speed. Poor performance will
result if ran much below recommended speed.
The Model 856 is designed to operate at 856 PTO speed. The variable pitch pulley will permit
operation at 750 PTO speed. To change the ratio, loosen the bolts under the gearbox. Loosen the
set screw on the side of the small pulley. Turn outer half of pulley clockwise and close
completely, then turn counterclockwise no more than 5 turns. The pulley should be 13/16" at top
of the V. Move the gearbox forward to tighten the belt and secure the bolts. The turbine shaft
should turn at 3600 RPM.
1. Inspect area to be vacuumed and pick up all harmful objects and litter. Rocks and other
harmful debris can do serious damage to vacuum assembly and cause bodily injury.
2. For best vacuuming results operate tractor at manufacturers’ recommended speed for best
cutting. If grass is high, reduce ground speed to prevent overloading mower and vacuum.
If grass is wet, wait until dry for best results.
3. When mowing, keep discharge chute to the outside of the cutting area for better cut of
grass and efficient pickup of grass clippings and leaves.
4. Do not overload cart. When it is filled shut off vacuum, disconnect hose at snap
disconnect, remove tailgate and dump.
5. When operating tractor on slope or grade, exercise much caution. Do not cut across grade
or slope. Mow directly up or down hill.
6. Periodically tighten all bolts.
7. Listen for unusual vibration of air turbine. If excessive vibration is present, STOP
vacuum and check for damaged blade.
8. Always shut off tractor engine before servicing vacuum.
9. Replace deflector shield when discharge chute is removed.
10. When removing clogs, SHUT OFF ALL engines.
Maintenance
Your 854/856 Trac-Vac has been serviced at the factory for initial operation.
Bearings should be greased and gearbox oil checked. Gearbox oil level should be to the bottom of
the cross shaft bearing. Overfilling will cause oil to be forced out though the vent. Fill with 90
weight gear lube.
Check belt tension after the first hour of operation and every ten hours thereafter.
On Model 856, adjust belt by moving gearbox forward.
On Model 854, adjust inboard belt first by moving jack shaft bearing to the rear, then adjust
outboard belt by moving gearbox forward.
