3.4 Equipment Matching
The Brandt Grain Vac 5000 was designed to be
used with agricultural tractors with the following
specifications:
-A minimum of 70 PTO horsepower
-The tractor PTO stub shaft must be 1000 rpm, 21
spline, 1 3/8” diameter. Do not use on a tractor
with 540 rpm PTO as there will be insufficient fan
speed to convey material.
-The tractor drawbar dimension must be 16 inches
(40 cm) from the end of the PTO stub shaft and the
centre of the drawbar hitch pin hole, see Figure 2.
Consult your tractor manual for the drawbar
adjustment procedure.
-The tractor hydraulic system must have one double
acting remote valve to operate the discharge auger
folding system. It must be capable of 2000 PSI at
an adequate flow to position the auger in a suitable
time. Either open or closed centre hydraulic systems
can be used.
-Never run the tractor RPM at greater than rated
PTO speed. Most tractors will allow speeds in
excess of the rated PTO speed. Overspeeding your
Grain Vac in this manner will reduce the life of the
machine, possibly cause serious damage and may
cause injury to the operator or bystanders.
3.5 Attaching / Unhooking
The Grain Vac should be parked on a level, dry
area that is free of debris and foreign objects. Use
the following procedure when hooking or unhooking
the Grain Vac.
A. To Hook to a Tractor
1. Clear all bystanders, especially children from the
area.
2. Make sure there is enough room to back the
tractor up to the hitch point.
3. Start the tractor and slowly back it up to the
hitch point.
4. Stop the tractor, place the park brake and
remove the ignition key before dismounting.
5. Install a drawbar pin with provisions for a
mechanical retainer. Install the mechanical
retainer.
6. Raise the implement hitch jack and rotate 90°
to place into it’s stowed position.
10. Check and clean the auger of obstructions that
may have hung up on internal hanger bearing
mounts.
11. Visually check the auger drive chain for dryness.
If the chain appears to be dry, it should be
lubricated with either a commercial aerosol chain
lubricant or a light oil.
12. Besure the lower body clean out is closed.
