Section 5: Maintenance/Repairs

WARNING Before inspecting, cleaning or servicing the unit, shut off engine, wait for all parts to come to a complete stop, disconnect spark plug wire and move wire away from spark plug. Remove ignition key on electric start models. Failure to follow these instructions can result in serious personal injury or property damage.

ADJUSTING TRIMMER

HEAD ENGAGEMENT

A.To test for correct belt tension, en- gage the control bail while the engine is running. If correct, the trimmer head will rotate when the control bail is pulled back fully against the handlebar.

B.If belt tension is too loose, the trim- mer head will move slowly or not at all and squealing from belt slippage may be heard when the bail is engaged.

C.If belt tension is too tight, the trim- mer head will rotate before the control bail is moved or when there is no free play in the bail.

D.To make an adjustment to belt ten- sion, shut off the engine, let all moving parts stop completely, and adjust the position of the two nuts on the stud shown in Figure 5-2 as described next:

1.To tighten belt tension, close the bail, move the upper nut (A, Figure 5-2) upward, then move the lower nut (B) upward. To loosen belt ten- sion, move the lower nut down and then the upper nut down. Tighten both nuts securely.

2.If adjustments over time move the nuts to the top of the threaded stud, the cable bracket (C) can be moved down the handlebar to the next hole. This permits a new range of adjust- ments.

REMOVING & REPLACING THE TRIMMER HEAD

A.Stop the engine and wait for all moving parts to stop. Disconnect spark plug wire and move it away from the spark plug. Remove the ignition key on electric start models.

B.Two bolts (A, Figure 5-3) secure the trimmer head (B) to the spindle head

(C). Loosen both bolts (not the nuts) sufficiently to open up the trimmer head enough to let it slide down the spindle head and past the two stops. Do not attempt to remove the bolts completely— they are permanently at- tached.

Install the new trimmer head in the same way the old unit was attached. Open it enough to slide it on the spin- dle head. Tighten the hardware se- curely (to 75 in/lbs.).

C.If the wear cup (D, Figure 5-3) is

also worn, replace it. To do so, insert a phillips head screwdriver in the hole at the top-front of the deck while remov- ing nut (E). Discard the old cup, posi- tion the new wear cup, and replace nut

(E) securely.

52051, 52052 specifications

Troy-Bilt has long been recognized for its commitment to quality and innovation in outdoor power equipment, and the Troy-Bilt 52052 and 52051 models are no exception. These garden tillers are designed to tackle a variety of tilling tasks, making them suitable for both novice gardeners and seasoned horticulturists.

The Troy-Bilt 52052 features a robust 4-cycle engine, which provides ample power to tackle tough soil conditions. With a displacement of 196 cc, this model is equipped to till soil up to 10 inches deep, ensuring that nutrients can be effectively mixed into your garden bed. The 52051 shares similar characteristics but is tailored for slightly different gardening needs. Both models feature an adjustable tilling width, allowing users to customize their tilling experience, with widths ranging from 16 to 21 inches. This versatility enables gardeners to efficiently navigate tight spaces or cover larger plots in fewer passes.

One of the standout technologies integrated into these models is the "Rear-Tine" design, which allows for smoother operation and superior maneuverability. This design feature not only enhances ease of use but also reduces strain on the user, making gardening tasks less daunting. The counter-rotating tines of the tillers are specifically designed to break up hard soil, allowing for effective aeration and preparation of planting beds.

Both models excel in terms of convenience, featuring a user-friendly starting system. The push-button electric start on the 52052 is particularly beneficial for those who may have difficulty with traditional pull-start mechanisms. Additionally, the tillers are designed with ergonomic controls, ensuring that users can operate them comfortably for extended periods.

Durability is another hallmark of the Troy-Bilt brand, and these tillers are constructed with high-quality materials to withstand the rigors of regular use. The heavy-duty steel tines are built to last, and the sturdy frame ensures stability while in operation.

In summary, the Troy-Bilt 52052 and 52051 garden tillers combine power, versatility, and user-friendly features, making them excellent choices for anyone looking to enhance their gardening experience. With their advanced technologies and robust construction, these tillers promise to deliver outstanding performance for all your gardening needs.
