This John Deere S690 (fall 2014) is carrying a 16 row corn header and running on our current SharpcoAG Poly/Steel tracks system. In addition to its over-the-road travel capability (no road surface damage) the dozer-tough polyurethane “Poly/Pad” insert track system also provides a dual rate of compaction of the soil in the soft field, similar in theory to laying a 3″ thick by 18″ wide wooden plank down and running over the top with a 30″ wide x 8 foot long steel dozer track. The center portion of the overall track footprint is compacted further and results in very little rear tire tracking inside the original tracks footprint. On this S690 shown, while cutting corn nearby, the rear tire tread “cleats” imprinted on top of the flattened area compacted by the tracks but did not reconfigure the footprint any further. Where the machine traveled through the row middles the field was compacted and flat. Only 7 rows over, the grain cart tires, in many places, were rutting deeply and rolling slower than the pulling tractor ground speed. The Case 9120 and John Deere 9870 (fall 2009) are running on the original steel-only versions. These same SharpcoAG steel tracks were also mounted and field-proven on a pair of John Deere 7760 cotton pickers in 2009. They successfully supported the weight of even those heavy machines as well, picking cotton through the last week of December in that very wet picking season. You might notice water standing in the middles.
These videos demonstrate that our tracks can support the heaviest of harvesting machines, even in late November/December (2009) Louisiana “gumbo” mud:
With the new design addition of the polyurethane, that shields the steel track from the road during travel, loading machines to haul between local fields is unnecessary. Long machine relocation distances can be made on its original tires. Once on location, because of the remounting accommodations built into our system, the tracks can be easily and quickly reinstalled.
The new finished product can be driven on pavement without destroying the pavement.
