SECTION I INTRODUCTION AND DESCRIPTION blades continue to cut the grass clippings several times before allowing the tiny pieces to fall to the ground. This eliminates a build up of grass residue on top of the lawn. The four caster wheel arrangement, along with the floating lift linkage and the standard front and center rollers, all work together to give an even cut and minimize scalping. 1-1 INTRODUCTION We are pleased to have you as a Bush Hog customer.

Raise and lower cutter to determine position with greatest distance between PTO shaft and gearbox input shaft.
G. Clamp end of driveline in a vice. Cut off shield where marked. (Figure 2-3). Figure 2-5 Figure 2-3 DANGER MAKE CERTAIN DRIVELINE YOKES ARE SECURELY FASTENED.

TIPS ON MOWING WITH A MULCHER The Bush Hog MP 5/6 is a finishing mower with counter rotating blade sets designed to do a superior job of mulching grass clippings. To get the maximum effectiveness from your MP the tips listed below should be followed: ● Mow often - In general, mulching operations require more frequent mowing than would conventional mowing procedures.
SECTION IV MAINTENANCE 8.During operation, listen for abnormal sounds which might indicate loose parts, damaged bearings, or other damage. Correct any deficiency before continuing operation. 4-1 MAINTENANCE CHECK LIST Perform scheduled maintenance as outlined below. Lower implement to ground, turn off tractor, and set parking brake before doing maintenance inspections or work. Some checks may require raising machine off ground and supporting with blocks.
4-3 BELT ADJUSTMENT 4-4 BELT REPLACEMENT Belt tensions should be checked every 40 hours to get maximum life from drive belts and best performance from the cutter. Belt tension is adjusted by increasing or decreasing the length of the spring on the moveable idlers. For proper belt tension on the mower, the spring lengths should be set at 2-7/8”. (Figure 4-2) To adjust the spring length, loosen or tighten the 3/8” hex nuts on the spring adjustment rod until the correct spring length is reached.
E. Remove the 3/8” - 24UNF x 7/8” Gr. 8 bladebolt and nut for each blade. Inspect the blade nut shoulder and the blade bolts for wear. Replace if necessary. F. When installing new blades on the mulching assembly, make sure that two blades are installed on the top side of the assembly 180° from each other and two on the bottom side of the assembly. The blades must mount on the rotation “pads” for proper operation. Assemble the (4) new blades to the blade holder using the blade nuts, bolts, and flatwahsers.
Figure 4-5 Blade And Spindle Assembly 4-6 BLADE SPINDLE SERVICE (Figure 4-5) Nut for Inner Shaft Flat Washer If shaft bearings or other parts require replacement, proceed as follows: Drive Sheave for Inner Shaft NOTE It is recommended that a Bush Hog dealer or other qualified person service the blade spindle. If blade spindles must be disassembled, special Bush Hog spanner wrenches are supplied for this operation. The Sheave Wrench is used on the outer shaft drive sheave.
