GENERAL INFORMATION

ENGINE

Three types of air-cooled engines are avail­able:

1) I H. P. Clinton 2) 2 H.P. Briggs & stratton or

Clinton 3) 3 H.P. Clinton

with speed ranges of 2000 to 3600 RPM, re­duced by the 50 to 1 speed reduction provid­ing a tractor walking speed of 1-3/4 to 2 -2/3 miles per hour. The engines use a regular unleaded gasoline gravity-fed from the eng­ine mounted gas tank (2 qt.). The engine crankcase capacity is one pint of oil; no oil dilution of the gasoline is necessary. An en­gine operation and service manual is prOvid­ed with each Choremaster. Read carefully the instructions governing operation, main­tenance, and adjustment.

DRIVE A V-Belt drive is used from the engine to a totally enclosed, precision machined, worm and worm wheel drive transmission. The 50 to 1 speed reduction provides two power take­offs: One from the high-speed sheave on the engine (2000 - 3600 RPM), the other from the axle shaft obtained by removing the axle cap and attaching a left hand stud and sprocket or pulley (40 - 64 rpm). The tractor driving clutch is totally enclosed by the hub, which is adapted to a 14" O.D. tirewitha demountable rim.

CENTRIFUGAL CLUTCH The engine take-off is through a V -Belt runn­ing on a 2-3/4" diameter plain double engine pulley or on the 2-3/4" diameter integral Centrifugal Clutch sheave. The Centrifugal Clutch is an automatic clutch which permits the starting and operation of the engine at less than 1900 RPM while the attachment will re­main idle. This feature permits stopping such attachments as the Sickle Bar, Power Lawn Mower, Seeder and others without stopping the engine.

The mercury filled Clutch is actuated by the centrifugal force of a column of mercury op­erating against friction plates which in turn bear against the housing frame. It engages at 1900 RPM when accelerated and disengages at 1600 RPM when decelerated No Oiling is required; the mercury clutch should give trouble-free performance. DO NOT AT­TEMPT TO SERVICE THE MERCURY CLUTCH. n trouble develops return n to your dealer for replacement.

FINGER TIP CONTROL

The Clutch control lever and latch, pinned to the left hand handle, is connected by a rod to the clutch control finger on the left hand housing.

This provides the Unkage operating the three jaw, hardened, spring loaded-type driving clutch.

The speed of the engine is controlled by means of a throttle lever located on the right hand handle. This lever is connected to the carb­uretor by means of a flexible steel tube with a section of piano wire threaded through it.

In this way, the operator can increase or de­crease the speed of the engine at will by ad­justing the throttle lever with the fingers of his right hand without taking his hand off the handle grip.

ATTACHMENTS

All attachments are mounted either from the engine mount (front), or from the rear cross member. Grass cutting attachments, such as sickle bar, rotary mower, reel-type mower, and snow plow, attach to the front (Engine Mount). All cultivating tools, such as duck feet, sweeps, spring tines, hoes, etc., attach to the rear main bracket and adjustable rear side mounting brackets by clips which take 3/4" standards.

MISCE LLANEOUS

The handles are removed by loosening the Allen screws located in the Left Hand and Right Hand housings and disconnecting the gas control wire and clutch rod. (Allen wrench is supplied with unit.)

The stand for the unit is located under the motor mount, being in this location for the purpose of adjusting tools when on level floor­ing or ground, and also for storage. The resting stand can be effectively tightened by striking the curved horizontal section between the two ground contact points with a hammer.

The tire rim is of the demountable type, two piece steel rim, bolted together with three 3/8" bolts and attached to the hub with three 3/8" studs and nuts. Proper inflation of the tire depends on the use of the tractor. Prop­er minimum is 15 -lbs., maximum 35 lbs. When considerable traction is required, such as plOwing, use 15 lbs. For average oper­ation use 25 lbs.

STAND

At rest the stand is in a vertical plane rest­ing against the shoulder on the rIght side of the engine mount. When ready to move for­ward, raise the handles and pull the Chore­master backward sliding the stand on the ground. Continue raising the handles until the stand snaps over the stop screw on the left side of the engine mount. The unit is now ready to move.

When stopping, reach forward with the left foot and kick the stand moving it off the stop screw. The unit is then moved forward ro­tating the stand to its position underneath the engine.

MOVEMENT

To move forward press the clutch latch and release the clutch hand lever. To stop the unit squeeze the clutch hand lever toward the handle grip, until it engages with the latch.

The new owner is advlsed to practice start­ing and stopping the Choremaster and to be­come familiar with its balance before using it for any particular job.

Consult the engine· manu~l regarding power and idling adjustments for the engine.

OPERATIONAL MAINTENANCE

1) Check the engine crankcase oil level and add the specified grade of Mobiloil if nec­essary before each use.

2) After the first 10 hours of use drain the engine cranckase and fill with clean oil. Thereafter, change the crankcase oil after each 25 hours of use.

3) After each 10 hours grease the clutch, when it is engaged, by giving the alemite fitting at the left end of the axle a few shots of Mobilgrease No. 5 or equivalent.

4) Check the transmission oil level after each 10 hours. Bring to proper level with Mobilube GX-140.

5) Occasionally, use Mobilgrease No.2 on the clutch finger mechanism.

6) Use a few drops of motor oil on the throt­tle cable and wire as::;embly to keep it in smooth working order.

7) Frequently check connections to make certain they remain tight. Dripping gas­oline is· not only dangerous, but is also wasted expense.

8) Check the Ure pressure and keep inflated.

9) If the stand becomes loose a sharp blow on the horizontal portion will tighten it.

10) The V -belt will eventually become slack. Adjust it by loosening the engine mounting bolts and moving the engine to the left; re­tighten the bolts.

Caution: Too much adjustment will cause tension in the belt and impose a greater load on the engine bear­ings.

11) Consult the engine manual for operational maintenance requirements for the engine.

ATTACHMENTS AND THEm USE

CU LTIV A TING

No one set of instructions is sufficient for all the various conditions that may occur in cul­tivating garden plants, however, a few gener­al instructions may be helpful.

Cultivation is used:

1. To kill the weeds that grow among the plants.

2. To conserve the moisture in the soil.

3. To prepare the surface soil to absorb more moisture.

The size of the plants to be cultivated and the soil conditions determine which tools to use. For instance, to weed the rows between young plants the best tools to use would be the hoes. By having the hoe wings extend toward the center the soil can be worked close to the plant. The hoes will not cover up the small plants.

When the plants are higher, however, the duck feet, sweeps, or cultivator steels would be the tools to use.

Page 10

SADDLE WEIGHT (40Ibs.) - A-0070

Weight used over wheel for added traction when cultivating. Also used on rear member as sickle bar counterbalance. Turn end for end and attach to rear member with hook. Rear member inserted from top of draw bar and may be raised or lowered for clearance.

SWIVEL HITCH & STABILIZER (A6025 & A6026)

The stabilizer and swivel hitch are used to­gether to give directional stability to the culti­vating group. This prevents wandering, spar­ing the operator the constant corrective move­ments necessary to keep a straight line.

BREAKING PLOW & STAKE (A6021)

Used to break ground before planting. A fine seed bed is prepared by following the use of the breaking plow with several duck feet, working perpendicular to the plowing oper­ation.

8" FURROWER & STAKE (A6024)

The furrowing tool aids in "laying off" straight garden rows in preparation for hand planting. Readily· adjustable to open ground for any size seed

CULTIVATOR STEEL & STAKE (A6046)

Eight inch. Preferred by many gardeners for thorough deep cultivation. For best results use 3 to 5 steels.

TURNING PLOW (and clip) (A6045-6 inch)

For the first operation in starting a garden. Turning and 'breaking light soil to a given depth; preparing small garden plots for re­planting.

SPRING TOOTH CULTIVATOR (A6016)

This 5-tooth cultivator is ideal for loosening the ground, and cultivating and removing weeds between rows. For most effective results use the spring tooth cultivator with the swivel hitch (less stabilizer).

STORAGE OF GROUND ENGAGING TOOLS

When tools are put away for the season, it is recommended that Mobilgrease No. 2 be used as a rust preventive coating
