OPERATION
A WARNING
■ Do not a llow c hildren or unqualified persons to
operate equipment.
■ Kee p bystanders away from equipment while it
is in operation.
A CAUTION
■ Stop mower and tractor immediately upon
striking an obstruction. Turn off engine, remove key, inspect and repair any damage before resuming operation.
■ Alway wear relatively tight and belted clothing
to avoid entanglement in moving parts. Wear sturdy, rough-soled work shoes and protective equipment for eyes, hands, hearing and head.
MOWING GRASS
Woods model 59, L59, and L306 series mowers are equipped with suction-type blades which make them ideal for finish mowing large areas of lawn. The machine should be run level when mowing, and the uncut area should be kept to the left side (right s ide o n left-handed machine). This prevents a small windrow that might otherwise occur .
Streaking
clear the ground. The side skid s will minimize sc alping by lifting the mower over bumps.
Height Adjustment (With Casters)
Adjustments for 59 and L59 casters are made by p lacing the axle in th e uppe r and low er hol e in the yo ke, or by moving spacers to top o r bottom of the pivot shaft. On L306, adjust by using variou s holes in caster arm. Adjust side skids 1/2" above the ground.
Raise mower off the ground when b acking and tur ning at same time.
Mower Attitude
Position front of mowe r level with or slightly bel ow the rear of mower to provid e a closer cutting . Mowing with the front end high will produ ce rag ged cuts with a s calloped look, exces sive shreddi ng, and will require extr a power.
Attitude Adjustment (Figure 1)
For best mowing results, dimension “A” should not be more than 1/2" higher, and never lower, than dimension “B”.
Dimension “B” is set by adjusting casters, gauge wheels, or lift chains.
Dimension “A” is set by raisin g or lowering pu sh channel arms in idler bracket.
With certain types of grass and under certain sea sonal conditions, the fro nt caster wheels may roll the grass down enough that it will no t come all the way back up and will not be cut as short as the surrounding area. This may appear to be a streak left by the spindle, but it is not. The only solution, under these conditions, is to carry the weight of the machine on the lift chains with the caster wheels adj usted up s o they c arry the we ight when riding a high ridge or high spot.
TRACTOR OPERATING INSTRUCTIONS
Operate the tractor at full governed rpm when doing normal mowing. If the forward speed is too high, a lower gear can be used.
Height Adjustment (Without Casters)
The mower is raised or lowered and the mowing height is maintained by the tractor hydraulic system.
Set the hydraulic control lever stop for the desired mowing level. Adjust the side skids so that they just
NOTICE
■ Any adjustment to either dimension “A” or “B”
will require adjustment to the other.
Check cutting height and attitude by placing a straight edge along the outside edge of the mower frame as shown in Figure 1.
Measure from the bottom edge of the straight edge at the front and rear at least 32" apart. The front measurement should be approximately 1/2" lower than the rear.
To det ermine cutting hei ght, it is necessa ry to subtract the distance the blade is below mower frame from the front measurement. On the L59, the blade is 4-5/8" below the mower frame. On the L306, it is 4-7/8" below.
When checking cutting height, be sure to take measurements on both sides of the mower. Be sure the mower is level from side to side usi ng these m easurements.
When changes are made to cutti ng height or attitude, be sure to check belt alignment and tension.
29936 (Rev. 5/18/2007)
Operation 7
Figure 1. Attitude Adjustment
NOTICE
■ Improper belt alignment or tension can cause
premature belt failure.
LUBRICATION
Grease caster pivot a nd wh eel ever y 8 hours of oper ation. There are grease fittings on each of the three blade spindles. These are accessible without shield removal. Grease every 24 hours of operation with a good grade light to medium grease gun.
NOTICE
■ Do not over grease spindles. Excess grease
could be transferred to the belt and cause slippage or premature failure.
BELT TENSION (SEE FIGURE 2)
Set belt tension using a spring scale or other force measuring d evic e. Remo ve l eft bel t shie ld. At t ach sca le between cutter and left pulley. Apply between three and four pounds of force. Belt deflection should measure 5/16" for normal conditions.
Te nsion may be in creased if nec essary to prevent belt from slipping in heavy mowing conditions.
When checking tension without a force measuring device, the belt, when properly set, should feel very tight.
Cycle belt through at least two revolutions after any adjustment before checking tension. These belts are very strong and need to be adjusted very tight. Belts are more likely to b e damaged by excessive slippage then from being overtightened.
Figure 2. Proper Belt Tension
NOTICE
■ Alig nment must b e rechecked if it is necessar y
to move idler pulleys to get proper belt tension.
■ Tension on a new belt should be readjusted
every half hour for the first two hours and then checked every eight hours of operation.
SIDE SHIELD & DISCHARGE CHUTE
Side shield and discharge chute are provided fo r discharge end of mower (left end on white frames and right end on yellow frames ). Use s ide shiel d for n ormal mowing and in areas where other persons may be present. Use discharge chute for very heavy mowing conditions.
NOTICE
■ Always use either side shield or discharge
chute.
OPTIONAL EQUIPMENT
Optional equipment a vailable includes casters for cutting height control, front roller to minimi ze s calpi ng, low and extra suction blades , and a leaf m ulche r. Low suction blades are for sa ndy areas where abras ive action could cause excessive blade wear. Extra suction blades are design ed to lift up fragile downed grass es for better cutting results and are also recommended for use with Woods leaf mulcher attachment.
NOTICE
■ Belt must not rub deck or crosswise support.
Te nsion ad ju stments m ay be mad e b y movi ng the idler pulleys up or down.
8 Operation
MOWER SPINDLE ASSEMBLIES
Mower spindle assemblies are equipped with two tapered roller bearings. Bearing adjustment is held by a roll pin. Adjustment should not be necessary. Repair requires special skills and tools. You may save time and money by using a new spindle assembly.
BLADE SERVICING
Keep blades sharp for a good mowing job. Sharpen both ends of the blade the same amount to maintain balance. Do not sharpen blade to a razor edge, but
29936 (Rev. 5/18/2007)
leave a 1/16" blunt edge . Do not sharpen back si de of blade. When replacing blades, do not substitute any bolt for the special Ny lok blade bo lt. The Nyl ock bolt is self-locking, meeting the non-loosening requirements for this application.
NOTICE
■ O n mowers with white frames, the blade bolts
have left hand threads.
Both 59 and 306 mowers use cup washers under blades. These washers wil l burn and lose their clamping force if excess slippage occurs. Inspect and replace as necessary. The L306 mower incorpo rates a friction clutch disc which is de signed to slip o nly when strikin g a solid object. Should blade slip during mowing, tighten by adding thin shim washers over bushing, between top cup washer and blade, until blades will hold desired load. Blade bolts should be torqued to 170 lbs-ft.
HOW TO SOLVE BELT PROBLEMS
Assemble as shown on mower decal. If not installed correctly, more twist will result than is allowable.
Belt whip is c aus ed by be lt m isa l ig nme nt unl e ss m owe r is driven by a rough-running or 2-cylinder engine.
Proper position of L59 and L306: Adjust mower forward and back to suc h a position tha t the rear take-u p idlers are near the bottom of their slots when the belt lines up with the proper groove in the center pulley and is tight. Never run the id ler s hig h in the s lo ts as thi s will cause misalignment.
Figure 3. Use of Straight Edge (Side View)
How to Align a Twisted Belt
Right: Inside edge of belt are approximately lined up with the sheave.
It is assumed that the mower is adjusted to run approximately level. If the front of the mower is down, the idlers will have to be rais ed. If the bac k of the m ower is down, the idlers will have to be down further. Belts must be in proper alignment with sheave grooves as shown in Figure 4 and Figure 5.
PTO pulleys must be moved in or ou t to c ause the belt to be in alignment with the idlers.
Belt Tension: Run belts very tight. Present belt designs are much strong er tha n we are a ccustom ed to and will stand more tensi on. Slip ping will hea t and rui n a belt but tension i s not h armful. You can minimize the amount of change in belt length as mower is raised and lowered by keeping the rear idlers adjusted to a low position.
