472H Potato Harvester Owner Operator’s Manual
3.10 PRIMARY BELTED CHAINS
The primary belted chains (See Fig. # 26) are located in the
digger section of the harvester. The rods come in various
patterns and pitches designed for the soil conditions.
See Section 6.2 for rod and pitch recommendations.
3.11 SECONDARY BELTED CHAINS
Fig. #26 Primary Belted Chain
Figure #27 Secondary Belted Chain
The digger (primary) section of the harvester places the po-
tatoes on the override and secondary belted chains (See
Fig. #27). The potato has a small drop from the digger
section of the harvester to the secondary belted chain. A
rubber cushion on the override and secondary belted chains
prevent the potatoes from bruising.
The secondary belted chain carries potatoes onto the rear
cross conveyor.
If excess dirt exists, have the rollers positioned so that they
are touching the rods, as opposed to underneath the belt.
This shakes the belted chain and allows excess dirt to fall
through the belted chain, without damaging the potatoes.
