Need help?Do you have a question about the DR ROTO-HOG Premier Power Tiller and is the answer not in the manual?
The DR® ROTO-HOG™ Premier Power Tiller is a robust and versatile piece of equipment designed for various tilling and gardening tasks, offering professional power and ease of use for homeowners. This manual outlines its functions, technical specifications, usage, and maintenance requirements.
The DR® ROTO-HOG™ Premier Power Tiller is primarily used for breaking up soil, preparing garden beds, and cultivating land. It features a powerful engine and a tine system designed for efficient soil penetration and mixing. The tiller is capable of both deep tilling for initial ground breaking and shallow cultivation for maintaining garden beds. Its design emphasizes user safety and operational convenience, making it suitable for a range of tasks from light cultivation to heavy-duty soil preparation. The machine is equipped with controls for engine operation, tine engagement, and depth adjustment, allowing users to tailor its performance to specific soil conditions and task requirements. It can also be connected to a Tow Vehicle for transport and for certain tilling operations, enhancing its versatility.
The DR® ROTO-HOG™ Premier Power Tiller is powered by a Briggs & Stratton 9.50 FPT, 208 CC, Single Cylinder engine. It has an approximate run time on a tank of fuel of 90 minutes. The towing type is a Pin Hitch. The ground clearance in transport mode is 1.5 inches, and the height adjustment is manual. The tine size is 12 inches, with a tine type of 12 inches and a number of tines of 12. The wheels are 15" x 6.00"-6 NHS (14" x 5.5"). The machine size is 39"W x 66"L (Transport), 35"H x 77"L (Lowest Position). The machine weight is 169 lbs, and the tongue weight is 50 lbs (Transport) or 112 lbs (Lowest Position). The shipping weight is 110 lbs. The gauge of steel on the shroud is 13, and the gauge of steel on the frame is 12 Gauge, 1.5" Tubular Steel. For engine oil, it requires 20 oz. (.60L) SAE 30 High Detergent Oil. The gasoline tank capacity is 3.2 Qts. (3.0 L) of unleaded gas (85 Octane minimum). The transmission oil level should be checked after the first 5 hours of operation, and SAE 30 non-detergent motor oil is recommended. The oil capacity is 22 oz.
The tiller is designed for ease of operation with clearly labeled controls for the choke, fuel shut-off, tine clutch lever, and lift handle. The depth stake allows for adjustable tilling depth, and a floating hitch is available for certain towing configurations. For starting, the choke control lever should be moved to the CHOKE position, the throttle control lever to RUN, and the recoil starter handle pulled with a smooth accelerating motion. Once the engine starts, the choke control lever should be moved to the RUN position. Breaking in the tiller involves engaging the tines in the air without contacting the soil, then engaging them in the soil at a slow speed.
When operating, it's crucial to maintain a safe distance from the rotating tines and wear appropriate safety gear. The tiller should be operated on slopes less than 5 degrees to avoid serious injury. For towing, the machine can be lifted by two people and attached to a Tow Vehicle using the SMOOTH-TRAK™ Hitch. The maximum safe towing speed is 10 mph. The depth stake can be adjusted to achieve the desired tilling depth, with a maximum adjustment of 5 inches.
The manual provides detailed instructions for various tilling operations, including initial ground breaking, cultivating existing gardens, and preparing seedbeds. It emphasizes the importance of adjusting tilling depth based on soil conditions and the specific task. For example, deep tilling is recommended for initial ground breaking, while shallower passes are suitable for subsequent cultivation. The manual also illustrates different tilling patterns, such as overlapping passes, to ensure thorough soil preparation.
Regular maintenance is crucial for the longevity and optimal performance of the DR® ROTO-HOG™ Premier Power Tiller. A maintenance checklist is provided, outlining tasks and their frequencies. Key maintenance items include:
The manual provides detailed instructions for adding engine oil, connecting the tiller to a tow vehicle, and adjusting the depth stake. It also covers removing and replacing the engine oil, transmission lubrication, and tine operation checks. For lubrication, the Tines Shaft requires grease using a grease gun every 8-10 hours, applying about ten (10) pumps of grease. The transmission oil level should be checked after the first 5 hours of operation, and SAE 30 non-detergent motor oil is recommended. Removing and replacing the V-Belt and checking the tine shear bolts are also covered, with specific instructions to ensure proper fit and safety.
Troubleshooting information is included to help users identify and resolve common issues such as the recoil not pulling out, the engine not starting, engine running but tines not moving, and excessive bounce or difficult handling. This comprehensive guide ensures that users can effectively maintain their tiller and address any operational problems that may arise.
