OPERATION 3.14 Roll Gap The roll gap controls the degree to which crop is conditioned as it passes through the rolls. Roll gap is factory-set at 6 mm (1/4 in.) for steel rolls, and approximately 3 mm (1/8 in.) for polyurethane rolls. Polyurethane rolls are better suited for crushing stems while providing reduced crimping and are recommended for alfalfa, clover, legumes and similar crops.
OPERATION 4. Steel Rolls: The length of thread (A) extending above the jam nut on the adjustment rods can be used as an approximation of roll gap but does NOT provide consistent roll gap measurements. Roll gap factory setting is 6 mm (1/4 in.). Refer to 3.14.3 Adjusting Roll Gap: Steel Rolls, page Figure 3.132: Roll Gap Adjustment...
OPERATION 3.14.3 Adjusting Roll Gap: Steel Rolls The length of thread extending above the jam nut on the adjustment rods can be used as an approximation of roll gap but does NOT provide consistent roll gap measurements. To ensure roll gap is at the factory setting, follow the procedure below.
OPERATION 3.15 Roll Tension Roll tension (the pressure holding the rolls together) is factory-set to maximum and is adjustable. Heavy crops or tough forage can cause the rolls to separate; therefore, maximum roll tension is required to ensure that materials are sufficiently crimped. To prevent over-conditioning of light alfalfa and short grasses, apply less roll tension.
OPERATION 3.16 Roll Timing For proper conditioning, the rolls must be properly timed with the bar on one roll centered between two bars on the other roll. The factory setting should be suitable for most crop conditions. IMPORTANT: Roll timing is critical when the roll gap is decreased because conditioning is affected, and the bars may contact each other.
Page 101
OPERATION NOTE: When setting roll timing, ensure the grease fittings (F) on both drivelines face towards the rear simultaneously. 2. Secure bottom roll (A). 3. Manually rotate the upper roll (B) in a counterclockwise direction until it stops. 4. Make a mark (C) across the yoke (D) and gearbox flange (E).
Page 102
OPERATION 6. Determine the center point (A) between the two marks on the yoke plate, and place a third mark. 7. Rotate the upper roll (B) in the counterclockwise direction until the bolt lines up with the third (center) mark. Figure 3.140: Conditioner Drive 8.
OPERATION 3.17 Roll Conditioner WARNING Keep everyone several hundred feet away from your operation. Ensure bystanders are never in line with the front or rear of the machine. Stones or other foreign objects can be ejected from either end with force. A wider windrow will generally dry faster and more evenly, resulting in less protein loss.
OPERATION 3.17.2 Positioning Forming Shield Rear Baffle: Roll Conditioner DANGER To avoid bodily injury or death from unexpected startup of machine, always stop engine and remove key from ignition before leaving operator's seat for any reason. The rear baffle primarily determines the height of the windrow, but can also affect the width. It is located immediately behind and above the conditioning rolls and can be positioned to do the following: •...
OPERATION 3.18 Haying Tips 3.18.1 Curing Curing crops quickly helps maintain the highest quality of crop material as 5% of protein is lost from hay for each day that it lays on the ground after cutting. Leaving the windrow as wide and fluffy as possible results in the quickest curing. Cured hay should be baled as soon as possible.
OPERATION 3.18.4 Windrow Characteristics Producing windrows with the recommended characteristics will achieve the greatest results. Refer to 3 Operation, page 21 for instructions on adjusting the header. Table 3.2 Recommended Windrow Characteristics Characteristic Advantage Enables airflow through windrow, which is more important to the curing High and fluffy process than direct sunlight Consistent formation (not bunching)
