4.Check for correct tension on the forward drive belt by taking two measurements of the cable spring, as follows:

a. With the Forward Clutch Bail (Y, Fig. 2-

6) in an open (released) position, measure

the length of the cable spring (W) from the

outermost coil to the outermost coil.

b. Squeeze the Forward Clutch Bail against

the handlebar (see Fig. 2-7) and re-mea-

sure the spring length. The belt tension is

correct if this second measurement is be-

tween 1/16" to 3/16" longer than the first

measurement. If so, turn the hex nut (Z,

Fig. 2-7) tightly against the cable adjuster

(X) while preventing the cable adjuster

from turning.

c. If the spring length is incorrect, you

must adjust the cable tension as described

in Checking and Adjusting Forward Drive

STEP 5: INSTALL REVERSE CLUTCH CABLE (MODELS 634F & 634A ONLY)

1.Unwrap the reverse clutch cable (CC, Fig. 2-8 and Fig. 2-9) from its shipping po- sition and route it up to the handlebar. Be sure that the cable is routed beneath the Forward Clutch Bail.

2.Insert the cable (CC, Fig. 2-8) through the slot in the cable bracket and position the flat side of the threaded assembly next to the flat side of the hole. Slide the hex nut (DD) up the cable and tighten it securely.

3.Fasten the reverse clutch cable to the left side handlebar with a cable tie (EE, Fig. 2-9).

4.Test the function of the reverse clutch by pulling out and releasing the cable knob. The knob should return to its neutral posi- tion (resting against bracket). If it doesn’t, contact your local dealer or Troy-Bilt LLC for technical assistance.

630C-Tuffy specifications

The Troy-Bilt 630C-Tuffy stands out as a reliable and robust garden tiller designed for homeowners and gardening enthusiasts looking to cultivate their gardens with ease. This tiller is particularly noted for its performance, durability, and user-friendly features, making it a favored choice among many.

One of the most prominent characteristics of the 630C-Tuffy is its powerful 208cc engine, which provides ample power for breaking up hard soil, turning compacted ground, and mixing in compost or fertilizers. This engine ensures that the tiller can handle a variety of tasks, from light tilling in a small garden to more demanding projects. The tiller features a 16-inch tilling width, allowing users to cover a significant area in a shorter amount of time while the adjustable tilling depth can be set from 1 to 7 inches to suit specific gardening needs.

A standout technology utilized in the Troy-Bilt 630C-Tuffy is its Counter-Rotating Tines (CRT). This innovation allows the tines to turn in the opposite direction of the wheels, creating a more effective and efficient tilling action. This design not only aids in breaking up the soil more thoroughly but also reduces the likelihood of the tiller becoming bogged down in tougher soil conditions.

The tiller is built with a sturdy steel frame and heavy-duty tines that ensure longevity and reliability even with repeated use. Its 6-position adjustable handle offers comfortable operation, enabling users to customize the height according to their preference, which helps reduce fatigue during long tilling sessions. Moreover, the Troy-Bilt 630C-Tuffy is equipped with a bump start feature, making it easy to start and operate.

For added convenience, this tiller features large, durable wheels that enhance maneuverability across various terrains, providing improved stability and traction. The 630C-Tuffy also boasts a folding handle for easier storage, allowing users to save space in their garages or sheds when not in use.

In summary, the Troy-Bilt 630C-Tuffy combines power, technology, and user-friendly features to deliver a top-tier gardening tool. With its ergonomic design, efficient tilling capabilities, and strong build, it is a valuable addition to any garden enthusiast's toolkit, ready to turn soil and nurture thriving gardens.
