Tailwheel Optional, Stump Jumper Optional

Tailwheel (Optional)

The tailwheel is ideal for mowing on relatively level ground, orchards, etc. It may not be too useful when mowing ditch banks and rough ground.

To install tailwheel, position angle frame with cross pipe of tailwheel frame between two forward lugs on center frame and install long pin provided. Attach spring cup assembly between the two rear lugs provided on center frame.

Height adjustment is accomplished by positioning spring cup attaching bolt into different holes in tailwheel tubular member. This is a spring-mounted tailwheel and will absorb some shock loading very well.

Stump Jumper (Optional)

Remove blade pins and blades from crossbar. Remove straps from pan assembly. Discard 3/16" thick spacer which is under keyhole plate.

Install one strap on stump jumper. Slide over crossbar. Install second strap. Align blade pin holes.

Insert blade pin through blade, stump jumper and crossbar. Secure with keyhole plate, lock plate and 1/2" bolt. Use as many blade pin shims as necessary so all freedom is taken from blade pin. Reassemble straps to pan as shown.

Control Valve Installation (Optional)

The valve provided is a single-spool valve set up for use with open-center hydraulic systems. Refer to page 27 for instructions to convert it for use with closed-center systems. Tractors with closed-center systems include: Ford, John Deere, MF1100-1300, Oliver 1755, 1855, 1955 and MM-1968 and later.

If tractor has an open-center system and pump delivers more than eight gallons per minute continuous flow, larger hoses and fittings in the valve will be required. The valves will handle 25 gallons per minute flow. Con- sult your tractor manual or dealer if necessary for type and capacity of your tractor hydraulic system.

Position valve on top of bracket as shown and secure with 3/8 x 2-1/2 bolts. Then position fender bracket on right hand fender so controls are convenient to the operator. If it is a narrow-type fender, also use inner brace (29), installing it on tire side of fender.

Drill four holes in fender and, using back-up bars (28) provided, bolt bracket to fender. If it is a wide, flat-top fender, discard inner place and attach main bracket directly to fender, again drilling four holes and using back-up bars provided.

Using diagonal brace bar, bending and drilling as required, to stiffen fender and valve bracket if it is not rigid enough without it. The narrow extension plate which extends forward on valve bracket is not used with single-spool valve and may be knocked off if it is in the way.

On the inlet (forward) side of valve, install a 1/2 x 3/8" adapter elbow. Into this, screw the 3/8 x 60" one-wire braid hydraulic hose. This hose must be attached to the tractor pressure system wherever it is appropriate. You may have to consult the tractor manual or your dealer to find out where to attach this.

On the return (outlet) side of valve, install a 3/4 x 1/2" reducing bushing followed by a 1/2 x 3/8" 90° adapter elbow. Position both elbows so hoses lie properly.

Install hose barb (37) into elbow fitting and on this, push self-clamping, low-pressure return hose. This will have to return to tractor hydraulic system reservoir at appropriate spot. Consult your tractor dealer or man- ual. Install other hose barb to tractor system and cut hose to desired length. Install on the barbs.

NOTE: Do not slip hose on until you are ready to leave it as hose cannot be removed from barb without cutting it.

Install control lever on valve. Screw 3/8 x 1/4" 90° adapter elbow into top of valve. To it, attach three foot hose which goes to coupler and cylinder.
