WHEEL ADJUSTMENT

The caster (forward slant of the king pin) and the camber (tilt of the wheels out at the top) require no

adjustment. Automotive steering principles have been used to determine the caster and camber on the trac-

tor. The front wheels should toe-in 1/8 inch.

To adjust the toe-in, follow these steps.

1.Remove the hex nut and lock washer, and drop the end of the tie rod from the axle bracket. See figure 17.

2.Loosen the hex jam nut on tie rod.

3.Adjust the tie rod assembly for correct toe-in.

CUTTING BLADES

A. Removal for Sharpening or Replacement

&WARNING: Be sure to disconnect and ground the spark plug wire and remove

ignition key before working on the cutting blade to prevent accidental engine start- ing. Protect hands by using heavy gloves or a rag to grasp the cutting blades.

1.Remove the large bolt and lock washer which holds the blade and adapter to the blade spindle.

2.Remove the blade and adapter from the spindle.

3.If the blade or blade adapter needs replacing, remove the two small bolts, lock washers and

nuts which hold the blade to the adapter.

B.Sharpening

Remove the cutting blades by following the directions of the preceding section.

When sharpening the blades, follow the original angle of grind as a guide. It is extremely important that each cutting edge receives an equal amount of grinding to prevent an unbalanced blade. An unbalanced blade will cause excessive vibration when rotating at high speeds, may cause damage to the mower and could break, causing personal injury.

The blade can be tested for balance by balancing it on a round shaft screwdriver. Remove metal from the heavy side until it balances evenly.

NOTE: It is recommended that the blade always be removed from the adapter for the best test of balance.

C. Reassembly

Before reassembling the blade and the blade adapter to the unit, lubricate the spindle and the inner surface of the blade adapter with light oil. Lubricating the bolt holes, bolts and inner surface of the nuts with light oil is also recommended. A 4 oz. plastic bottle of light oil lubricant is available. Order part number 737-0170.

Engine oil may also be used.

When replacing blades, be sure to install the blade with the side of the blade marked "Bottom" (or with part number) facing the ground when the mower is in the operating position.

Blade Mounting Torque

3/8" Dia. Bolt 450 in. lb. min., 600 in. lb. max. 5/16" Dia. Bolt 200 in. lb. rain., 350 in. lb. max.

To insure safe operation of your unit, all nuts and bolts must be checked periodically for correct tightness.
