2. INSTALLATION INSTRUCTIONS CAUTION CAUTION LIFT AND SUPPORT ALL LOADER COMPONENTS SAFELY. EQUIP YOUR TRACTOR WITH A ROPS CAB OR FRAME FOR YOUR PROTECTION. SEE YOUR TRACTOR/ROPS OPERATOR MANUAL FOR CORRECT SEAT BELT USAGE. HOSE KIT HOOKUP: Install hoses to loader hydraulic steel tubing. Install male quick couplers (customer furnished) to 1/2” male pipe ends of hoses. Refer to Figure 1. Read entire instructions before beginning to install the loader.
Quick Draw Latch Attach: Before installing loader to tractor, install quick draw latch attach to loader. Using a hoist, install bucket or attachment to your quick draw latch attach. Refer to Figure 5 and pages 27 & 28 for quick draw latch attach instructions. Following these instructions will add stability to loader package and will allow easier handling of loader with a hoist. NOTE: Some Models of the 3860 Loader have been designed to custom fit specific makes and models of tractors.
Using a hoist to support the loader frame, align the subframe crosstube with the front bracket. Refer to Figure 7 and Figures 2, 3, & 4, page 10. 8 7 9 CAUTION LIFT AND SUPPORT ALL LOADER COMPONENTS SAFELY. 3 1 Figure 9 (1) Hinge nut. (2) Hinge assembly. (3) Snap pin in loader mounted position. (4) Hardened flatwasher. (5) Rear hinge pin. (6) Subframe bushing. (7) Subframe pedestal. (8) Center mounting bracket tubes. (9) Rear hinge pin outer hole. TORQUE IDENTIFICATION 2 (1) Subframe Crosstube.
3. PRE-OPERATION INSTRUCTIONS EXTERNAL LOADER AND/OR TRACTOR VALVE IMPORTANT: Do not extend bucket cylinders without quick draw latch attach installed on loader. Failure to follow these instructions could cause attachment cylinder damage and will void loader warranty. CAUTION WHEN PROPERLY INSTALLED, THE TRACTOR REMOTE VALVE OR EXTERNAL VALVE CONTROL LEVER/LEVERS WILL CONTROL THE LOADER HYDRAULIC CIRCUITS AS SHOWN IN FIGURES 2 AND 3.
LOADER MOUNTED CONTROL VALVE EQUIPPED WITH 2 OR 3 CONTROL HANDLES OR TRACTOR REMOTE VALVE EQUIPPED WITH 2 OR 3 CONTROL HANDLES CAUTION BEFORE LEAVING THE TRACTOR SEAT, LOWER ATTACHMENT OR LOADER BOOM TO GROUND, STOP ENGINE, LOCK BRAKES, RELIEVE HYDRAULIC PRESSURE, AND REMOVE KEY. If your loader utilizes a loader mounted control valve equipped with 2 or 3 control handles or tractor remote valve equipped with 2 or 3 control handles, it will function as described in Figure 3.
REMOTE HOSES SUPPORT THIRD CYLINDER TUBE KIT (OPTIONAL) After installing loader onto tractor, raise the loader to full height, stop engine, lock brakes, and remove key. Then gather remote hoses and install nylon tie through hose support hole located in right hand loader subframe. Secure hoses as shown. This will allow remote hoses to be supported by loader frame instead of loader steel tubing. Refer to Figure 5. Install two steel tubes to inside of right hand loader boom.
4. MAINTENANCE Check all hardware daily before operation. Tighten hardware to torque values as specified in the Torque Chart, page 43 unless otherwise specified. IMPORTANT: Lower the loader boom to the ground and relieve pressure in loader hydraulic lines prior to doing any service or maintenance operations on the tractor or loader. Check the tractor hydraulic fluid level as specified in the tractor Operator Manual. With the engine off and the bucket on the ground, inspect all hoses for cuts or wear.
CAUTION DO NOT STAND, WALK OR WORK UNDER A RAISED LOADER OR ATTACHMENT UNLESS IT IS SECURELY BLOCKED OR HELD IN POSITION. ACCIDENTAL MOVEMENT OR A CONTROL LEVER/LEVERS OR LEAKS IN THE HYDRAULIC SYSTEM COULD CAUSE THE LOADER TO DROP, OR ATTACHMENT TO DUMP, CAUSING SEVERE INJURY. 1 QUICK DRAW LATCH ATTACH LUBRICATION Figure 4 (1) Spring cover plate, one each side. Your quick draw latch attach handle springs and pin areas have been pre-lubricated and sealed at the factory.
FILLING THE BUCKET Approach and enter the pile with a level bucket. ...a level bucket throughout the lifting cycle resists bucket lift and increases breakaway effort. NOTE; Do not be concerned if the bucket is not completely filled during each pass. Maximum productivity is determined by the amount of material loaded in a given period of time. Time is lost if two or more attempts are made to fill the bucket on each pass.
CARRYING THE LOAD DUMPING THE BUCKET Position the bucket as low as possible below the level of the tractor hood for maximum stability and visibility, whether the bucket is loaded or empty. Lift the bucket high enough to clear the side of the vehicle. Move the tractor in as close to the side of the vehicle as possible, then dump the bucket. Use extreme caution when operating the loader on a slope and keep the bucket as low as possible.
OPERATING WITH FLOAT CONTROL During hard surface operation, keep the bucket level and put the lift control in the float position to permit the bucket to float on the working surface. If hydraulic down pressure is exerted on the bucket, it will wear faster than normal. FLOAT Sidecutting is a good technique for cutting down a big pile. The float will also prevent the mixing of surface material with stockpile material.
PEELING AND SCRAPING BACKFILLING 6” Backgrade occasionally with a loaded bucket to keep the working surface free of ruts and holes. Hold the lift control forward in float position so the full weight of the bucket is scraping the ground. Use only the heel of the bucket while backgrading. Use a slight bucket angle, travel forward, and hold the lift control forward to start the cut. Make a short, angle cut approximately 6” deep and break-out cleanly.
HANDLING LARGE HEAVY OBJECTS WARNING DO NOT USE FRONT END LOADERS FOR HANDLING LARGE HEAVY OBJECTS SUCH AS LOGS OR OIL DRUMS. HANDLE LARGE ROUND HAY BALES ONLY WHEN LOADER IS EQUIPPED WITH BUSH HOG BALE SPEAR ATTACHMENT OR BUCKET WITH 4 TINE GRAPPLE. Leave dirt in the bucket because dumping on each pass wastes time. HANDLING LARGE HEAVY OBJECTS CAN BE EXTREMELY DANGEROUS DUE TO: ★ Possibility of rolling the tractor over. ★ Possibility of upending the tractor.
TROUBLESHOOTING PROCEDURES PROBLEM POSSIBLE CAUSE Loader slow and/or will not dump. Hydraulic oil to heavy. Oil filter plugged. Hydraulic pump worn. Oil line restricted or leaking. REMEDY Change to proper oil. Clean or replace filter. Repair or replace pump. Check all hoses and tubes for leaks, damage or restrictions. Replace damaged or restricted hoses or tube lines. Quick couplers not properly connected. Check connection - Replace if necessary. Control valve does not shift properly.
6. DISMOUNTING THE LOADER Remove the two clevis pins holding the two parking stands in the storage position. Refer to Figure 2. CAUTION ALWAYS PARK LOADER WITH MATERIAL BUCKET OR AUTHORIZED BUSH HOG ATTACHMENT ATTACHED TO THE LOADER. BEFORE LEAVING THE TRACTOR SEAT, LOWER ATTACHMENT OR LOADER BOOM TO GROUND, STOP ENGINE, LOCK BRAKES, RELIEVE HYDRAULIC PRESSURE AND REMOVE KEY. 1 DO NOT STAND, WALK, OR WORK UNDER A RAISED LOADER OR ATTACHMENT UNLESS IT IS SECURELY BLOCKED OR HELD IN POSITION.
Raise the loader boom and retract the bucket cylinders. Lower the loader boom until the parking stands make contact with the ground. Dump the bucket until the bucket touches the ground. Refer to Figure 4. 7 8 9 3 Figure 6 Start the tractor and position the valve control lever in the float position.
