Stopping the Engineand Tiller

1.Tostop the wheelsandtines, releasethe Forward Clutch Bail (all models) orthe Re-

verse Clutch Control (Model 634A) -- whichever control is in use.

2.Tostop the engine, put the ignition switch and/or the throttle control lever in the "OFF"or "STOP" position.

OPERATINGTHE TILLER

Thefollowing operating instructions pro- vide guidelines to using your tiller effec- tively and safely. Besure to read Tilling Tips & Techniquesin this Section before actually putting the tines into the soil.

NOTE:This is a traditional "Standard-Ro- tating-Tine" (SRT)tiller with forward rotat- ing tines, it operatescompletely differently from "Counter-Rotating-Tine" (CRT)tillers or from front-tine tillers.

1.Followthe Pre-Start Checklistat the be- ginning of this Section. Besure that the wheelsare in the WHEELDRIVEposition.

2.Movethe DepthRegulator Lever all the way down, so that the tines clear the ground. Usethis position when practicing with the tiller and when traveling between tilling sites. Beforeactually tilling, move the lever to the desired depth setting (see Tilling Tips & Techniques).

3.Start engineand allow it to warm up. Then put throttle in "FAST"setting.

4.For forwardmotion of the wheels and tines:

(a) Pull Forward Clutch Bail (Fig. 4-1) up

against handlebar.Releasebail to stop for- ward motion of wheels and tines.

(b) When tilling, relaxand let the wheels

pull the unit while the tines dig. Walk be- hind anda little to oneside of the unit. Use

one hand, yet keepa light--but secure-- grip on the handlebar (while keepingyour arm loose). SeeFig. 4-2. Let the unit move at its own paceand do not push down on the handlebarsto try and forcethe tines to dig deeper-- this takes weight off the wheels, reducestraction, andcauses the tines to try and propel the tiller.

,_ downWARNING:onthe handlebarstoDonotpushtry to makethe tiller till more

deeply.This prevents the

wheelsfrom holding the tiller backand can allow the tines to

rapidly propelthe tiller forward, which could resultin loss of

control, property damage,or personal injury.

5.For reverse motion of the wheelsand tines (Model 634A only):

(a) Look behindand exercisecaution when operating in reverse.Do not till while in reverse.

(b)Stop all forward motion. Lift handlebar with one handuntil tines areoff the ground andthen pull ReverseClutch Control knob

out (seeFig. 4-3). Tostop reversing, let go of ReverseClutch Control knob.

6.To movethe Model 630C in reversefor short distances:

(a)Releaseforward Clutch Bail. Thenlift handlebaruntil tines are off the ground.

(b)Swing the handlebarto the left so the right wheeltakes a "step" backward.Next swing the handlebarto the right so the left wheel"steps" backward. Repeatas needed.

(c)If longer distances needto becovered in reverse,shut off the engine, then place the two wheels in FREEWHEEL.

7. ToTurn the Tiller Around:

(a)Practiceturning the tiller in a level,

openarea. Beverycarefulto keepyour feet and legs away from the tines.

(b)Tobeginaturn, lift the handlebarsuntil the tinesareout ofthe groundandtheengine andtinesarebalancedoverthe wheels(Fig. 4-4).

(c)With tiller balanced,push sideways on handlebarto steer in direction of turn (Fig. 4-5). After turning, slowly lower tines into soil to resumetilling.

tines are out of groundand unit is balanced.
