SECTION 3 – OPERATION LAND ROLLER OPERATION SAFETY 1. READ AND UNDERSTAND Operator’s Manual before using machine. Review at least annually thereafter. 2. VERIFY that all safety devices and shields are in place before using machine. 3. KEEP hands, feet, hair and clothing away from moving parts. 4. STOP engine, place all controls in neutral, set parking brake, remove ignition key and wait for all moving parts to stop before servicing, adjusting, maintaining or unplugging. 5.
SECTION 3 – OPERATION INITIAL HOOKUP: 1. Make tractor to hitch connection with locking draw pin and safety chain. 2. Retract jack and rotate into storage position. 3. Insure that tips and couplers are CLEAN. Plug Center Tilt Cylinder hoses into desired tractor outlet. Adjust hydraulic flow rate to 35% of maximum. 4. Plug Wing Lift Cylinder hoses into desired tractor outlet. Adjust hydraulic flow rate to 35% of maximum. 5. Connect safety Light Kit wiring harness to 7 pin receptacle. 6.
SECTION 3 – OPERATION STEPS REQUIRED TO UNFOLD FROM TRANSPORT TO FIELD POSITION: 1. WARNING: Land Roller must be attached directly to tractor drawbar and not an intermediate towed vehicle or implement. Loss of control could result causing serious injury or death to you or others. 2. Ability to safely operate the Summers Land Roller is determined by both tractor horsepower and weight. The minimum tractor weight for operating this implement is 16,000 lb. Minimum tractor engine horsepower is 160.
SECTION 3 – OPERATION 6. Operate tractor hydraulics from operator station only. Do not allow anyone to stand near Land Roller when folding or unfolding. Do not raise or lower Land Roller when implement is moving. 7. Fully extend Center Tilt Cylinder, Wings will rotate rearward, maintain hydraulic pressure an additional 5 seconds to insure cylinder and hoses are fully charged with oil. Retract Center Tilt cylinder approximately 1/2”. 8. Lower wings with caution by fully extending Wing Lift cylinders.
SECTION 3 – OPERATION LAND ROLLER FIELD OPERATION: 1. If Land Roller is in Transport Position, follow “Steps Required to Unfold Land Roller from Transport to Field Position”, page 3-3. 2. When in field position, place Center Tilt Cylinder remote into float position. This will allow rollers to self level. 3. Choose an operating speed which achieves desired results. Operating at over 7 MPH will decrease effectiveness and increase chance of immovable rocks denting roller tube.
SECTION 3 – OPERATION PROCEDURE TO ADJUST HYDRAULIC CYLINDER ATTACH EYE BOLTS: Refer to the drawing and photo on next page before adjusting Attachment Eye Bolts. Follow these steps: 1. Adjust Wing Lift Cylinder Eye Bolts FIRST. Adjust Eye Bolts so Wing Stop and Roller rest on Center contact areas when Wing Lift Cylinder is fully retracted. a. If Wing does not contact Center, lower wing, relieve hydraulic pressure and adjust Eye Bolt towards machine center line. b.
SECTION 3 – OPERATION 3-7
SECTION 3 – OPERATION TRANSPORTING LAND ROLLER: 1. If Land Roller is in Field Position, follow “Steps Required to Fold Land Roller from Field to Transport Position”, page 3-5. 2. Ability to safely operate the Summers Superroller is determined by both tractor horsepower and weight. The minimum tractor weight for operating this implement is 16,000 lbs. Minimum tractor engine horsepower is 160. Dual tires or single tires set at maximum width are required for safe operation of Land Roller. 3.
SECTION 3 – OPERATION UNHOOKING LAND ROLLER FROM TRACTOR IN FIELD POSITION (HIGHLY RECOMMENDED): 1. WARNING: It is highly recommended to unhook Land Roller in Field Position ONLY. unhook Land Roller if positioned hydraulically between Field and Transport Position. NEVER 2. Choose a firm level surface with enough open area that will allow unfolding Land Roller without contacting any obstructions.
SECTION 3 – OPERATION C. Block tires to prevent movement after hitch pin is removed. D. Check that hitch pin is not bound with side or front to back pressure. If hitch pin is not free, carefully reposition tractor. E. With hitch pin free, if hitch piece lifts up on tractor drawbar, negative tongue weight exists. DO NOT UNHOOK LAND ROLLER WITH NEGATIVE TONGUE WEIGHT.
SECTION 4 – MAINTENANCE MAINTENANCE SAFETY 1. STOP engine, place all controls in neutral, set parking brake, remove ignition key and wait for all moving parts to stop before servicing, adjusting or maintaining. 2. BE CAREFUL when working around high pressure hydraulic system. 3. ALWAYS make sure that Land Roller is lowered into field position (cylinders extended), it is blocked to prevent movement and pressure is relieved from hydraulic circuits before servicing. 4.
SECTION 4 – MAINTENANCE STORAGE 1. Follow steps outlined in “UNHOOKING LAND ROLLER FROM TRACTOR IN FIELD POSITION”. 2. Clean and remove all excessive dirt and grease from Land Roller. 3. Grease all zerks. 4. To prevent rusting, repaint any areas that have been worn, chipped or scratched. 5. Apply grease* to any exposed part of cylinder shafts. *NOTE: Before returning Land Roller into service, all grease must be removed from cylinder shafts to prevent damage to seals.
SECTION 4 – MAINTENANCE PROPER BOLT USE DO NOT use these values if a different torque value or tightening procedure is given for a specific application. Torque values listed are for general use only. Check tightness of fasteners periodically.

History of Summers Manufacturing Co., Inc. 1965 – Summers Manufacturing is founded by Harley Summers, who purchases patent rights for Goebel truck and pickup hoists from the Goebel Brothers of Lehr, ND. These hoists, produced in Harley Summers’ blacksmith shop the first year, were distributed nationwide by a Cincinnati, Ohio, dealer. With increasing sales, the company soon outgrows the small shop. Summers wins the Herman harrow contract, beginning the company’s Herman culti-harrow line.
