McD Ground-Drive Lime Spreader

Originally appeared in Volume 28 Issue 3 of Small Farmer’s Journal and copyrighted in this form thereto

LUBRICATION

All bearings and moving parts should be lubricated as indicated in Illustration 1.

ADJUSTING

This Trailing Lime Spreader is designed to be operated with the fans level when the wagon or truck is empty.

The length of drawbars should be adjusted by using the holes in rear end so that front edge of hopper will just clear the wagon or truck bed.

The holes in hitch clamp, together with the holes in quadrant, provide adjustment for leveling the spreader.

OPERATING

To avoid unnecessary wear on parts, throw spreader out of gear when transporting.

At a speed of five miles per hour, the width of cast is approximately 21 feet, while a slower speed will give a lesser cast.

The amount of material spread per acre is regulated by slides in the bottom of hopper and the speed of travel. Both slides should be opened the same distance to obtain an equal distribution of material.

When feed openings are set at 2 ¼”, this machine will spread approximately two tons of crushed limestone per acre when traveling at a speed of five miles per hour. This quantity will vary, depending upon the weight of the material and its condition, particularly the moisture content.

For maximum service a speed not exceeding five miles per hour is recommended.

INSTRUCTIONS FOR SETTING UP

Lubricate all bearings and moving parts as you proceed, and see that they work freely.

Bolts must be used in the holes in which they are found, or in parts to which they are attached, unless otherwise shown. Leave nuts loose until all parts of any assembly are in place, then tighten.

Shaded portions in illustrations show parts to be assembled; these must be placed on machine in the order numbered.

Wherever the terms “Right” and “Left” are used, it should be understood to mean from a position behind and facing the machine.

We reserve the right to make changes or improvements in the design or construction of any part without incurring the obligation to install such changes on any machine previously delivered.

1.With drawbars straddling the quadrant, bolt rear end of drawbars to pivot strap and quadrant.

2. Remove pins from ends of axle. Put on wheels. (Washer must be in place between cotter in axle and inner end of each wheel hub.) The ratchet caps are right and left and must be so placed. Replace pins through ratchet caps and axle. Secure pins with cotters.

3. Remove set screws, agitator pins, spacer collar and cupped washer from agitator shaft. Put hopper in place and bolt it to bed angle. Put felt washer in cupped washer and place on agitator shaft with felt washer next to hopper bottom. Replace spacer collar, agitator pins and set screws in agitator shaft. See Illustration 3A.

4. Bolt brace to front end of hopper and to quadrant.

5. Assemble hitch clamp on rear cross member of wagon or truck bed.

6. Hitch spreader to hitch clamp.
