C. Use two 9/16-inch wrenches to remove the bolts which attach the tines to the holders. (Tines

are not attached to cast iron holders with bolts. In the case of cast iron holders, remove each gang [set of four tines] from a holder by removing only one bolt, and then loosening the other three bolts on the same gang.)

D. Always discard old hardware

and tines. Use only the hardware which came with your new tines.

Bolt Removal Tips

❑ Loosen all four nuts on a holder plate or tine gang before trying to remove any of the nuts and bolts. ❑ If necessary, use penetrating oil to loosen stubborn nuts. ❑ If necessary, place the closed (boxed) end of a wrench on the nut and sharply tap the wrench with the

rubber mallet until the nut is loose.

If You Ordered Custom

Tines...

Custom tines (special, hardfaced tines which last up to 21/2 times longer than standard tines) are perfect for tilling sandy, gritty soil, or for custom tilling or market gardening.

If you received Custom tines, read this General Information and then follow the standard tine installation instructions which apply to your particular model tiller.

If you have any difficulty installing your Custom tines, contact our Service Department (Refer to the back cover of this manual.)

Step 1: Check Your Parts

Remove the tines and hardware package and check that you received all of the parts listed below for your model tiller. If any parts are missing or damaged, contact our Technical Service Department and we will arrange for replacements.

To prevent serious personal injury when removing or installing your bolo tines:

• Stop the engine, and remove the electric start key (if your tiller features electric start).

• Let the engine and muffler area cool.

• Disconnect the spark plug wire, and position the wire away from the plug to prevent accidental starting.

WARNING

Tine edges can be sharp and can have slivers that could cause personal injury. Use care at all times when handling tines. The tine hood edges may also be sharp. To prevent personal injury, wear thick gloves when touching the edges of the hood.

CAUTION

Step 2: Tine Removal

A. Carefully tilt the tiller forward until the engine is resting on the ground. (On some models it may be necessary to prop up the rear of the tiller or to add additional weight to the engine to stabilize the tiller in this position.)

B. Raise the tiller hood flap and secure it out of the way with a rubber band, string or, in the case of the PONY tiller, with the depth regulator adjustment bar knob.

PRE-INSTALLATION STEPS

Page 3

Step 3: Tine Identification

Separate the sixteen new tines

into two groups: eight left-

curved tines and eight rightcurved tines. Tines can be

identified as either left-curved or right-curved tines in two ways:

Figure 1: Look for "L" or "R" stamped on the tines.

Figure 4: Insertion of bolts.

Step 4: Bolt Installation

NOTE: Skip this step if you have a HORSE Model tiller with cast iron tine holders.

A. On all other models, place the sixteen bolts through the holes in the tine holders with the threaded ends of the bolts pointing outward toward each side of the tiller as shown below in Figure 4.

(The installation of tines on holders is described later in these instructions.)

Figure 3: Right-curved tine.

Figure 2: Left-curved tine.

B. Or, hold the tine with the

blunt edge toward you. If the tip curves toward the left, the tine is a left-curved tine. If the

tip

curves toward the right, the tine is a right-curved tine. See Figures 2 and 3 which show the two types of tines.

A. The letters and numbers stamped on the side of each tine are factory code marks which contain either an "L" (on leftcurved tines) or an "R" (on rightcurved tines). See Figure 1.

Blunt Edge

B. Sort lock washers and nuts into four groups of four each.

Figure 5: Cutting edges of tines must enter the soil first when the tiller moves forward.

MPORTANT: Tines rotate in the same direction as the

wheels. During the installation steps, place tines on holders so cutting edges (not the blunt, wider edges) will enter the soil first when the tiller moves forward. See Figure 5.

Use this procedure to install tines only if your tine holders are shaped as shown below in Figure 7.

NOTE: Be sure to use the specific tines (left or right curved) called for in each installation step.

HORSE MODEL TINE INSTALLATION

(WELDED STEEL HOLDERS)

Figure 7: Welded steel tine holder.

Step 1: Position Holders Before Starting Tine Installation

On PTO Models, disengage the PTO Lever. On non-PTO Models, place the Forward/ Reverse Lever in Neutral.

Rotate the tine holders and shaft (by hand) until any one of the semi-circles on the

outer

mounting plates of the holders is at the 12 o'clock position in relation to the ground. See Figure 8 on Page 5.

Step 2: Install Tines on Left Inner Holder

Tines used in this step:

Step 5: Check the Installation

This completes the installation of the tines. To ensure that the installation is correct, check for the following:

❑ Make sure that the tips of the four innermost tines (on the left and right sides) are directly opposite each

other and pointing toward each other. See Figure 20.

❑ Make sure that the cutting edges of all tines will enter the soil first when the tiller is moving forward.

❑ Also read and follow the instructions provided in the Bolo Tines Maintenance Section on Page 16.

Figure 20: Tines installed on cast iron holders.

Installation Tips

If you encounter difficulty in aligning the two holes when

inserting the fourth bolt, check the following:

❑ Make sure that the bolts in the other three sets of holes are as

loose as possible.

❑ Use a screwdriver inserted through the two empty holes to pry

the tines together.

❑ Use a mallet to lightly tap the tines into the proper position.

❑ If the holes still cannot be aligned, remove the tine gangs from

the holder, remove the holder from the tine shaft and examine the holder for rough spots in the groove between the lugs. Smooth any rough spots with a metal file and repeat Steps A through C. Refer to your Owner/Operator Manual for holder removal and replacement instructions.

Step 2: Install Tines on Right Outer Holder

Tines used in this step:

two left-curved tines

followed by

two right-curved tines.

Check the Installation

This completes the tine installation of tines on the ECONO HORSE Model. To ensure that the installation is correct, check for the following:

❑ Make sure that the tips of the

four innermost tines on the outer holders are pointing toward each other and inward (toward the transmission housing). See Figure 25.

❑ Make sure that the cutting

edges of all tines will enter

the soil first when the tiller is moving forward.

Also read and follow the instructions provided in the Bolo Tines Maintenance Section on Page 16.

Figure 25: ECONO HORSE tines installed.

Innermost Tines

Page 16

BOLO TINES MAINTENANCE

Check Bolts and Nuts

Check all tine attachment bolts

and nuts for tightness every 10 hours of tiller operation.

Inspect Tines for Wear

Inspect tines after the first 10

to 15 hours of tiller operation

and then after every 10 hours. See Figure 26.

Compare your tines to those shown in Figure 26 to decide whether your tines need replacement. Your tines should be replaced when the following conditions occur:

❑ Tines are worn beyond the

line shown in Figure 26.

❑ Tines do not dig more than 3

to 5 inches and do not perform well for burying crop residue and for sod busting.

❑ Tines leave a wide, untilled

gap in the middle of a tilled row, so that overlapping becomes very timeconsuming.

Rotate HORSE and ECONO HORSE Tines for Longer Tine Life

HORSE and ECONO HORSE bolo tines can be rotated to obtain a longer life. PONY tines are subject to equal wear because the tine pattern is the same for all tines on a holder. Therefore, rotating tines is not effective for that model.

❑ Rotate tines once during their life cycle to increase tine life up to

40%.

❑ Rotate tines to equalize wear among the tines.

❑ Rotate tines before they wear beyond the line shown in Figure 26.

Figure 26: New and worn tines.
