​Mantis 7940 Tiller Cultivator Review

My Rating:​​​​​

Cultivators and tillers are excellent tools for any gardening enthusiast to have in their shed. This is particularly true for homeowners with medium to large gardens or for those who are starting from scratch. Compacted sod and dirt make it difficult for plants and grass to thrive.

Although cultivators and tillers look quite similar, they are actually intended to perform different functions; however, the advent of modern technology had led to the development of tools that are capable of doing both jobs – just like the Mantis Tiller Cultivator 7940.. 

Read on to find out more about what this unique model has to offer!

If you are looking for a heavy duty tiller that is capable of handling the most difficult jobs you can throw at it, look no further than the Mantis Tiller Cultivator 7940. This unique garden tool can be used to cultivate, power-weed, till, or dig. It weighs in at only 24 pounds – making it easily maneuverable for most people.

Built to last and exceptionally durable, Mantis backs this model with a 5 year consumer warranty. The length of the warranty is a standout in this industry. A lifetime warranty against breakage is also offered on the steel tines.

Mantis also sells additional tools that enable this tiller cultivator also to be used as an aerator, dethatcher, plow, and border edger. Reviewers state that the attachments are inexpensive and simple to attach.

A Honda 4 cycle engine powers the Mantis 7940 The engine’s unique placement directly over the tines ensures that it delivers the maximum amount of digging power. This commercial grade 25cc engine makes the tines spin twice as fast as other comparable models, and the tines can rotate up to 240 rotations per minute. Because the engine is gas only (4-stroke), there is no need to mix any fuel.

The wide grip handles of the Mantis 7940 are ergonomically designed and well-cushioned. This design reduces the amount of strain and fatigue placed on a user’s shoulders and back. The throttle controls are within reach of a user’s fingertips, which makes it easy to control this unit while it is in use. It has a maximum soil penetration depth of 10 inches; however, if the tiller needs to be used for cultivation, the tines can simply be turned around to penetrate only the top 2-3 inches of soil.

When not in use, the handles of this tiller cultivator fold down to make it readily transportable and reduce the amount of storage space it needs. The design also includes a convenient kickstand to make the fueling process easier and to hold it upright while in storage.
