IMPORT ANT FEDERAL LA WS AND REGULA TIONS* CONCERNING EMPLOYERS, EMPLOYEES AND OPERA TIONS. *(This section is intended to explain in broad terms the concept and effect of the following federal laws and regulations. It is not intended as a legal interpretation of the laws and should not be considered as such).
SECTION I INTRODUCTION AND DESCRIPTION 1-1 INTRODUCTION We are pleased to have you as a Bush Hog cus- tomer. Your Front End Loader has been carefully designed to give maximum service with minimum down time.
T able 1-1 TECHNICAL SPECIFICA TIONS G E J C B A H F D XX ZZ W X Y Z U V VV 9 SERIES LOADER M246 M146 A. Maximum Lift Height - Measured at Pivot Pin 103 in. 86 in. B. Maximum Lift Height - Under Level Bucket 96 in. 81 in. C. Clearance with Attachment Dumped 45° 77 in.
SECTION II LOADER MOUNTING AND DISMOUNTING TRACTORS THAT HAVE MOVABLE AXLES MUST BE SET FORWARD IN THE LONG WHEEL- BASE POSITION AS SHOWN IN FIGURE 2-1 TO PREVENT EXCESSIVE LEVERAGE BEING EXERTED ON THE TRACTOR FRAME. FAILURE TO DO SO CAN RESULT IN PERSONAL INJURY AND EQUIPMENT DAMAGE.
C. Check that lift cylinders are fully retracted. Figure 2-3. Then drive tractor forward. Use bucket cylinders to position height of outer pedestal top pin. Figure 2-4. Figure 2-4 Outer Pedestal Top Pin Clamp And Pins In Stored Position D. Align outer pedestal top pin with mounting bracket guide post on both sides.
IMPORTANT Each time after mounting the loader, operate loader for a short period of time, then retighten the quick attach nuts. Check nuts for tightness during normal maintenance H. Remove parking stands from the parked posi- tion and return them to their storage positions in the cross tube.
F. Rollback bucket slightly while lowering loader boom down until the parking stands make firm con- tact with ground. Dump bucket until bucket touches the ground. NOTE Driving the tractor forward slowly while position- ing loader will allow parking stands to contact ground firmly.
3-6 LOADER MOUNTED SERIES CON- TROL V AL VE EQUIPPED WITH SINGLE LEVER CONTROL HANDLE If your loader utilizes a loader mounted series con- trol valve equipped with single lever control handle, it will function as shown in Figure 3-2. 3-4 EXTERNAL LOADER AND/OR TRAC- TOR V AL VE.
3-10 LOADER OPERA TION Before operating the loader, fully raise and lower the boom three or four times. Then raise the loader bucket approximately four (4) feet above the ground and cycle the bucket two or three times. Lower the bucket or attachment to the ground.
16 NOTE: Do not be concerned if the bucket is not com- pletely filled during each pass. Maximum productivi- ty is determined by the amount of material loaded in a given period of time. T ime is lost if two or more attempts are made to fill the bucket on each pass.
LIFTING THE LOAD WARNING DO NOT LIFT OR CARRY ANYONE IN THE BUCKET OR ON ANY OTHER POSITION OF THE LOADER OR LOADER ATTACH- MENT. INADVERTENT MOVEMENT OF THE LOADER OR ATTACHMENT COULD RESULT IN SERIOUS INJURY OR DEATH FROM FALLING OR CRUSHING.
OPERA TING WITH FLOA T 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.
PEELING AND SCRAPING BACKFILLING 6” 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. With the bucket level, start a cut at the notch approx- imately 2” deep.
Leave dirt in the bucket because dumping on each pass wastes time. Operate at right angles to the ditch. Take as big a bite as the tractor can handle without lugging down. DITCH SOIL PILE DITCH Leave dirt which drifts over the side of the bucket for final clean-up.
Figure 3-4 Fork Lift Attachment Adjustable Forks 21 3-16 QUICK HITCH OPERA TION (M246 ONLY) The quick hitch (Figure 3-5) is designed to allow easy mounting and dismounting of skid steer attachments from loader. With attachment on flat, level surface, mount as follows: Tilt quick hitch slightly forward at top and slowly drive into attachment.
SECTION IV MAINTENANCE 4-1 MAINTENANCE CHECK LIST Perform scheduled maintenance as outlined below. Lower machine to ground, turn off tractor, and set parking brake before doing maintenance inspections or work. All bolts should be torqued as recommend- ed in torque chart unless otherwise indicated.
4-3 HYDRAULIC SYSTEM PRESSURE REQUIREMENTS A tractor hydraulic system pressure setting of 2500 psi is recommended for maximum efficiency and ser- vice. Do not exceed 3000 psi as this will damage components possibly causing serious injury. The Bush Hog control valve is pre-set at the factory and should not be adjusted.
TROUBLESHOOTING PROCEDURES PROBLEM POSSIBLE CAUSE REMEDY Loader slow and/or will not dump. Hydraulic oil too heavy. Change to proper oil. Oil filter plugged. Clean or replace filter. Hydraulic pump worn. Repair or replace pump. Oil line restricted or leaking.
SECTION V ASSEMBL Y 1. Do not lift heavy parts or assemblies. Use crane, jack, tackle, fork trucks, or other mechanical devices. 2 Select an area for assembly that is clean and free of any debris which might cause persons working on the assembly to trip.
5-2 TRACTOR BALLAST Tractor weight bracket may be left in place on cer- tain tractor models with loader mounted. Front trac- tor weights can only be used when the loader is parked. Weights must be removed before remount- ing loader or serious damage will occur to loader or tractor front axle due to excessive weight.
