The Earthquake Walk Behind String Mower, powered by a 160cc 4-Cycle Viper engine with, is the perfect all-terrain tool for making short work of your trimming and brush clearing tasks. In contrast to push mowers or hand-held trimmers, the Earthquake String Mower is designed to help you go where mowers can't while eliminating the back strain associated with carrying heavy equipment all around the yard. Built-tough features like a one-piece steel deck and heavy-duty nylon line ensure continuous results and make the experience of slicing through weeds and dense foliage quick, easy, and satisfying. In addition to being tough, this unit is also convenient, utilizing large diameter, extra wide wheels to keep you coasting around your property over uneven terrain and through thick grass and weeds. An integrated clutch and hand bail system safely keeps the String Mower motor running, but disengages and stops the trimmer head if you need to clear debris, eliminating the need to re-start your motor each time. When the job is complete, you simply wheel the unit back to the garage and fold down the handlebars for easier storage. Backed by a 5-year product warranty, US-based customer service, this product is built to perform. 5-Year Limited Warranty

For additional information on this product, please see the Product Documents section for all downloadable user manuals, installation guides, brochures and warranty statements.

  • POWERFUL - Powered by a strong, 160cc 4-Cycle Viper engine. The Earthquake Walk Behind String Mower chops down your unsightly weeds and stubborn brush with ease. The large 14-inch wheels allow you to float through thick grass, weeds, brush, nettles, and other foliage too difficult for push mowers to overcome.
  • DURABLE - Our one-piece steel deck provides strength and stability while reducing vibration. Super tough nylon line has a cutting swath of 22 to get the job done quickly.
  • CONVENIENT- Never-go-flat wheels ensure that your equipment is ready to go when you are. An integrated clutch and hand bail system safely keeps the String Mower motor running, but disengages and stops the trimmer head if you need to clear debris, eliminating the need to re-start your motor each time.
  • OUT-OF-THE-BOX: The setup is super simple with virtually zero assembly required. Simply unfold and tighten the tool-less handlebar knobs. Also included in the box are starter strings for the mower head and 4 cycle engine oil.
  • WARRANTY AND SERVICE: Earthquake is committed to providing a great product and an even better user experience which is why the Earthquake Walk Behind String Mower is backed by a 5-year limited warranty.

Q: Can you use a blade instead of string for thicker stalks

18 days ago
1 Answer
  • AI-generated, Human-approved
    A: No, this mower relies on a flexible nylon string rather than a metal blade. It is designed to cut through woody-stemmed weeds up to 1/4 inch in diameter using heavy-duty 0.155-inch nylon line, but attempting to use it on thicker, rigid saplings will snap or melt the line.

Most Helpful Favorable Review

Best option short of a bushhog!

3 years ago
This Walk Behind String Trimmer is a beast when it comes to clearing the path around you. Its .155 diameter string holds up really well and the 21.5" replacement line is easy to change when it does run out. It is fantastic on level ground. However, its downfall is that it is a bear to push uphill and a little tough to hold back on the downhill.

Most Helpful Critical Review

Used once, returned next day...

3 years ago
Underpowered, bogged down in 4" to 6" grass and weeds, not for use on uneven ground. Needs multiple line attachments rather than just two, difficult to control cutting depth/length of material. Nose is bulky and will not allow close cropping unless the trimmer line is at maximum length, trim line provided is consumed very quickly. Recoil start requires near horizontal pull, too low, needs throttle control other than bar on handle to engage and disengage trimmer head, Oil dipstick difficult to check; tucked location and threaded. Reviews appear misleading, perhaps the newer model version with throttle control, self propelled, head drive lever, and re-located recoil start will address some of these issues...

Great for North GA under brush

Exceeded expectations!

14 days ago
I bought this to maintain around my pond on the edges that I can’t get my big mower to. It exceeded my expectations. What took me several hours with a weedeater, I finished in just under an hour. It also looks way better than the weedeater. Knee high thick grass and small shrubs were no match. Highly recommended!

Yes, I recommend this product.

Poorly designed trimmer Head

19 days ago
The good: The engine runs well and the wheels are big and wide and it rolls easy. The bad: The little metal loops that the string attaches to break easily. I have had the loops break off my first machine within 30 days. TSC replaced it without issue. The same thing happened to the replacement machine so tractor supply refunded my money and the extra money that I purchased the extended warranty. Previously I purchased a cub cadet walk behind string trimmer that lasted 8 years of heavy use. TSC no longer carries this unit.

No, I do not recommend this product.

Review 1

Works OK but has some design problems.

20 days ago
The good: It clears ground pretty well and has a good amount of power. It's easy to swing around to hit things from multiple angles. It starts easily and runs well. It was comfortable to use. I like being able to let go of the hand bale and keep the engine running. The bad: It was always getting stuff wound around the output shaft inside the cutting head cylinder. If I adjusted it up to try and avoid that, it didn't happen as much but was harder to clear. Also that meant raising the cutting height. The cutting head is attached to the output shaft by two allen bolts. In order to clean out the cutting head you have to remove the spinning disc at the bottom, loosen those two bolt, and then pull the head off. Sometimes you have to smack it pretty hard to get it off. The first time I put it back together I did not tighten the bolts enough, and the spinning disc fell off and the cutting head slipped down. I reassembled and tightened them further, but it is only a matter of time before they strip or break off in there. Also, in order to fully open the air filter cover, you have to remove the left wheel. What genius design engineer thought that was a good idea? The same one who designed a car that you have to remove the engine from the bay to change the spark plugs? I returned it to the store. Now that I have some experience with this type of machine I can select a better one.
