Loading Material

Confined Space Entrapment/Suffocation Hazard:
Never enter a hopper for loading or unloading.

Once used for hazardous fertilizer or treated seed, dangerous
concentrations of fumes may be present even in an empty
hopper with the lid open.

Even with small amounts of otherwise harmless material
loaded, the atmosphere inside the hopper may have insufficient
oxygen or high levels of choking dust.

1.

Securely hitch cart or drill+cart to a tractor with
adequate weight and power. Park cart on solid, level
ground. See Tractor Requirements, “Specifications
and Capacities
” on page 107.

Note: Static tongue weight of a loaded cart is about

5,500 pounds (2500 kg) on level ground and more
when facing downhill.

Refer to Figure 21
2.

At each hopper to be loaded, if meter box clean-out
door

was completely closed, open it. See “Meter

Doors” on page 24. If the cart has been parked for
more than a day, condensation may have caused
moisture to accumulate.

3.

Wipe seals and meter bottom flanges clean. Close
and latch clean-out doors.

4.

With the cart fan running, check hopper-lid and
meter-box seals carefully for air leaks. Adjust bin
latch or replace seals to prevent leakage.

5.

Shut off all hydraulic power to the cart.

Population Risk:
Before first cart use, and at the beginning of each season,
check the entire bin for leaks. A small air leak can cause large
variations in seeding rates.

Refer to Figure 22
6.

Set the Auger Direction Valve control handle to
center, off position.

Refer to Figure 23
7.

Set the cart diverter valve to the down (Auger)
position. See “Diverter Valve” on page 22.

8.

Climb the steps to the cart walkboard. Unlatch and
open the lid. See “Lid Opening” on page 20.

9.

Check that the strainer basket is in place in the top of
the bin. Remove any foreign material from the
basket.
