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

2 months 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.

PUSH VS HAMD HELD

This is a good push behind weed wacker. Especially for a senior citizen. Not like the hand held one where it get difficult to carry and hold on to.

Yes, I recommend this product.

Avoid like the plauge

I bought the String mower a year ago. They use a cheap nylon idler pulley which chipped and cut the drive belt belt. I have been trying to get a replacement pulley for three months and it is still on backorder. So I am out $80 For the belt and pulley and still waiting for the pulley to arrive from Vietnam. Wish I had bought a DR mower.

No, I do not recommend this product.
