Page 24: Field Cleaning
6.5 Field Cleaning The harvester will collect mud at different rates during operation depending on soil conditions. It is important to clean the machine every two hours, or more often if the conditions demand. IMPORTANT: If left unclean, mud will clog the machine and cause imminent damage. Frequently clean the machine to avoid damage. -
Page 25: Row Finder
6.8 Row Finder Amity harvesters have the option of a hydraulic row finder attachment. The Row finder helps keep the lifter struts di- rectly in line with crop rows. See section 7.1 for adjustments. Figure 6-4: Row Finder 6.9 Digging Depth Digging depth varies with soil and crop conditions. -
Page 26: Scrapers
6.11 Scrapers Scrapers keep the Lifter Wheels clean by removing mud and dirt off the wheels. In turn, the Lifter Wheels are able to turn freely and lift beets. Amity lifting struts are available with two types of scrapers, top or bottom. Bottom scrapers come standard with the Single Plate Strut. -
Page 27: Grabroll Bed
6.14 Grabroll Bed Grabroll beds provide the majority of the cleaning action within the harvester. Grabrolls with scroll- ing provide an aggressive push to beets. Beets are continually turned and flipped over so that the entire beet is cleaned. Scrolled grabrolls will also thoroughly remove mud and break up dirt clods. The smooth grabrolls turn slightly faster than the scrolled and provide a wedging action to remove dirt, tailings, and debris. -
Page 28: Wheel Option
6.16 Wheel Option The wheel option is available for those whose soil is lighter or who do not want chains. The bed consists of the standard jump chain. Figure 6-15: Wheel Harvester 6.17 Scrub Chain The scrub chain lifts beets from the rear grabrolls to the tank. -
Page 29: Steering Axles
6.19 Steering Axles Amity offers the option of steerable rear axles. This allows the harvester to have a shorter turning radius and increased con- trol over the rear of the machine. Figure 6-18: Steering Axle 6.20 Machine Shutdown To ensure maximum life of the machine, follow this procedure when stopping: 1. -
Page 30: Adjustments
7.0 ADJUSTMENTS 7.1 Row Finder When harvesting, the row finder wands should be adjusted like Figure 7-1 such that there is 5 inches (12.7 cm) of contact between the ground and row finder wands. Adjustment spring (B), shown in Figure 7-2, can be adjusted to apply more down pressure to ensure constant contact with the beet row. -
Page 31: Front Hitch
7.2 Front Hitch Using the hydraulic cylinders on the front hitch, raise or lower the front of the machine to achieve proper digging depth. CAUTION: Raise the front of the machine to the highest position when turning or traveling at high speeds. -
Page 32: Pinch Point Position
7.4 Pinch Point Position The pinch point position can be adjusted by a spacer (G), part number 50139. In muddy conditions, roll the pinch point forward by adding spacers. This will pop the beet faster and with less mud. For dry or hard digging condi- tions, roll the pinch point back by removing spacers, giving the wheels a longer time to lift the beet and reduce break- age in the ground. -
Page 33: Pinch Point Width
7.5 Pinch Point Width Matching pinch point to crop size is important to maximize yield and minimize tare. If the pinch point is too wide, smaller roots may be left in the ground, resulting in a larger digging depth. In turn, more dirt will be put in the harvester. -
Page 34: Wheel Fillers
7.6 Wheel Fillers 7.6.1 Adding or Removing Center Mount Wheel Fillers 1. Remove the lock nut, lock washer, and flat washer from bolts (B) as shown in Figure 7-11. 2.
