PRE-OPERATION
GENERAL
Read the entire Owner's Manual before attempting to
operate this manure spreader. Before attempting any
maintenance or repairs; always be sure all rotating
parts have stopped and that the tractor is shut off, dis-
connect the PTO, relieve all hydraulic pressure and
disconnect hydraulic hoses.
WARNING
NEVER OPERATE SPREADER WITH ANY GUARDS
OR SHIELDS REMOVED. FAILURE TO HEED MAY
RESULT IN SERIOUS PERSONAL INJURY OR
DEATH.
1. Completely lubricate the unit as described in the
LUBRICATION Section.
2. Check and tighten the wheel lug nuts if required.
3. Check and maintain the tire pressure according to
the manufacturer’s recommendation.
4. Check the entire unit for loose bolts, damaged or
loose hydraulic fittings and hoses or other damaged
parts.
5. The tractor half of the PTO drive shaft assembly
must be locked securely to the tractor output shaft.
TRACTOR HOOKUP
Tractor Requirements:
1. The spreader is designed to be operated by a 540
rpm PTO tractor output. In addition, 1 set of tractor re-
mote hydraulic ports are required, to operate the apron
drive and a second set of ports will be required for an
optional hydraulic end gate.
2. The PTO drive shaft assembly is designed to oper-
ate with tractors conforming to the industry standard
shown on Figure 1 for 540 RPM PTO output.
Tractor Size
1. The spreader does not have brakes. Towing the
spreader must be done safely. The ASAE (American
Society of Agricultural Engineers) specifies that the
towing vehicle should weigh at least 2/3 as much as the
loaded implement to be reasonably safe towing at
speeds up to 20 mph. This (20 mph) is also the maxi-
mum recommended towing speed for the spreader.
2. The loaded weight of your spreader will naturally
vary with the moisture of the manure and you must
consider that for your conditions. The loaded weight
capacities as specified by the spreader manufacturer
are as follows:

TION.
