BiG X

• Optimaize is a versatile and unique system
• Gearbox on the chopping drum switches flexibly from short cuts to long cuts
• Switching the drum speed takes a few minutes
• No downtime, no machine conversion, no up-front planning

Forming an integral part of the pulley, KRONE VariLOC is a gearbox that alters the speed of the chopping drum. By simply changing the drum speed from 1250 to 800 rpm using a standard open-end wrench, you can increase the chopping drum’s LOC range by up to 53%. This system allows operators to momentarily change from short to long chops and vice versa and meet different customer needs without a major changeover - this is the concept of OptiMaize. In conjunction with the roller conditioner with 105/123 teeth or with the disc conditioner, this technology turns the BiG X into a real all-round forage harvester that offers its owner and user maximum flexibility.

Great flexibility:
The KRONE VariLOC is available for the MaxFlow drums with 28 and 36 blades. VariLOC is a mechanical gearbox that allows the MaxFlow chopping drum to produce the full range of chop lengths (OptiMaize S-XL) with 28 or 36 blades.

Wide cutting range:
The KRONE VariLOC increases the cutting lengths that are available from the MaxFlow chopping drums with 28 and 36 blades. For the 36-blade drum it increases the range by 50% from 3-17mm to 3-24mm. For the 28-blade drum it increases the range even by 53%, which means from 4-21mm to 4-30mm. This allows operators to adjust the chop length flexibly as the application changes.
