Remove roll pins from swivel fitting P/N 2172. Turn swivel fitting on brake rod P/N 5100 in, to tighten. Just enough to prevent brake from slipping when engaged. 2. Reinstall roll pin. CAUTION: Over tightening may cause premature wear on brake band P/N 5085. . Page 3 of 13 THE FOLLOWING INSTRUCTIONS REFER TO 42" MOWER DECKS: INSTALLATION: 1. Position mower deck assembly under frame, raise front of mower deck assembly enough to allow cross shaft P/N 1332 to slide through frame guides and mower deck guides. Install (2) washers P/N 3094 and (1) hair pin cotter P/N 3072 on each end of the cross shaft. 2. Attach short L-rod P/N 1355 to lift arm as shown in drawing. 3. Attach long L -rod P/N 1409 to rear lift arms as shown in drawing. Page 4 of 13 4. NOTE: It is possible to install the engine to mower deck drive belt P/N 6111 at this time; however, our engine manufacturers have suggested that this belt be installed after the engine has been fully serviced per manufacturers' suggestions and allowed to o perate at 1 /2 to 3/4 throttle settings for approximately (3) minutes. This will place the initial start up of the engine in a no load situation and allow complete engine lubrication. ADJUSTMENT: 1. Install engine to mower deck drive belt P/N 6111. 2. Check and adjust tire pressures: Front 19 to 21 psi; Rear 8 to 12 psi. Tires may have been over inflated for shipping purposes. 3. Place the mower on a level surface. Using the lift handle, raise the mower deck to a height which will allow measurements to be taken from the surface to the tops of the two outer mower deck cutter blades P/N 8688. 4. Align both outer mower deck cutter blades to obtain a side to side measurement. Starting with the left blade as viewed from operator's position, secure measure ment from level surface to the bottom of the cutter blade tip, rotate blade and check measurement on opposite end of cutter blade. Tip to tip measurement on the same cutter blade should not vary more than 1 /8th of an inch. Maintain measurement taken and v erify against the right outer cutter blade. If adjustment is required, loosen or tighten the nuts on the two rear L-rods. 5. Align both outer mower deck cutter blades front to rear as viewed from operator's position. Measure from surface to the bottom of the cutter blade tip, at the rear of the mower deck. Using the nut on the single front L-rod, loosen or tighten as required to place the mower deck approximately 1 /8th of an inch higher in the rear than the front of the deck. 6. Re-check belt routing and alignment, start engine, burnish in electric blade clutch using at least (5) engagements at 3/4 to full throttle settings. Each engagement should last approximately (5) seconds. NOTE: The completed adjustment places the mower deck in a position which wi ll produce a quality cut. Ground speed, grass conditions, types of grass, tire pressures, dull or bent blades and loose belts are just some of the factors which will cause poor cut quality.
