Refer to Figure 2-6. Correct Angle 19376 Incorrect Angle 19377 Bucket Digging Angle Figure 2-5 When loading trucks, curling the bucket close to the dipper stick will prevent undue spillage when the bucket is raised so that it can be dumped in the truck bed. To obtain a level bottom, set the bucket teeth at a slight angle. Keep this angle as you drag the bucket with the dipper stick by gradually uncurling the bucket. Intermittently pull the boom lever at the same time to maintain a level bottom. 19371 Level Bottom Figure 2-6 Land Pride Table of Contents Section 3: Maintenance and Lubrication Maintenance Proper servicing and adjustment can increase the life of any implement. With careful and systematic inspection, you can avoid costly maintenance, time and repair. ! CAUTION! For safety reasons, each maintenance operation must be performed with the backhoe lowered completely to the ground or folded with the transport boom lock engaged and the tractor engine shut off with ignition key removed. • After using the backhoe for several hours, check all bolts to be sure they are tight. • Lubricate items as listed under Lubrication, this section, starting on page 22. • Replace any worn, damaged or illegible safety labels by obtaining new labels from your Land Pride Dealer. Information about labels is located under Safety Labels in the “Important Safety Information” section starting on page 1. Storage For short periods coat all exposed cylinder shafts with grease or a corrosion preventive. Install dust caps on the quick couplers, if equipped, to prevent dirt contamination of the hydraulic system. Or, if possible, connect the quick couplers together. At the end of the working season or when the backhoe will not be used for a long period, it is good practice to clean off any dirt or grease that may have accumulated on the backhoe and any of the moving parts. It may be necessary to scrape off compacted dirt from the bucket, then use a garden hose to thoroughly clean the surface. Inspect the backhoe for loose, damaged or worn parts and adjust or replace if needed. Lubricate as noted in the Lubrication portion of this section starting on page 22. Repaint parts where paint is worn or scratched to prevent rust. Aerosol touch-up paint is available from your Land Pride dealer. Order Land Pride part # 821-002C for Black. Store backhoe in a clean, dry place. Bucket Tooth Replacement To remove a tooth: 1. Heat the tooth with a torch at point “A” (this is the compressed area that overlaps “B”). 2. Hammer at the top of the tooth until the tooth comes free from the shank. To replace a tooth: 1. Hammer the tooth onto the shank. 2. Heat at point “A” and hammer the heated section into recess “B”.
