John Deere's 17.8-cm (7-in.) wide diamond-tread design ensures fast bale starts and grips the bale to prevent slippage and reduce chaffing. The treads are self-cleaning to reduce carryover.
The belts are staggered to reduce the loss of fine material and are closely spaced to contain the hay for fast, easy starts.
The belts enclose 91 percent of the bale width to reduce the loss of fine material and retain hay quality.
The staggered belt roll design enables any loose hay under or behind the belts to be returned to the pickup and into the baler.
This design helps to prevent buildup at the front of the baler, which could cause hay loss and belt or splice damage.
The 449 and 459E Balers use three-ply belts. The belts are constructed of three-ply nylon-polyester combination:
- They have the strength to handle heavy-shock loads and help to maintain consistent belt length.
- Polyester is used for increased strength and reduced belt stretch.
Extra-service-life belt splices
The 449 and 459E Balers use extra-service-life, rectangular, wire-belt splices:
- Flat surface reduces wear on the splice as the belt travels around the rolls.
- Strong hook shape increases the splice life as the belt flexes.
The material thickness and bend radius resist the opening of hook points and reduce metal fatigue.
