The Mantis 4-Cycle Tiller Cultivator 7940
The Mantis 7940 is basically a 4-cycle version of the 2-cycle Mantis 7920, which means that you won’t be mixing oil and gas together. There is a fuel tank and an oil reservoir on this model.
And, what about the Mantis’ engine? Well, this sparkler is using a 25cc Honda motor! And, along with Troy-Bilt machines, Honda is just about the most reliable outdoor machinery on the market!
This heavy-duty 7940 comes with most of the same perks as its younger sibling, the 7920.
Advantages Of The Mantis 7940
Lightweight – It tips the scales at less than 25 pounds…making it almost a pleasure to carry around anywhere.
Honda 25cc Engine – You don’t get a much better power equipment engine than this!
Easy To Start – After turning on the switch, located on the handle; 1) prime the bulb 6 to 8 times, 2) put the choke lever on FULL CHOKE…in the “up” position, 3) gently pull the cord out until it offers resistance, 4) then pull the cord sharply, and…BANG-A-DA-BOOM…you’ve got an engine running smoothly. Let it warm up for a few minutes, push the choke lever to the “down” position, and off you go. Starting a warm engine is even simpler…just turn on the switch and use steps 3) and 4)…that’s all!
Tilling Width – A respectable 9 inches…and, if the tines are flipped around, this little baby becomes a master weeder, navigating through rows and around plants and clipping off weeds just a few inches below the soil line…with no trouble at all.
Tilling Depth – It will dig down up to an amazing 10 inches into the dirt…which is plenty sufficient to create a loose, loamy soil bed for your plants.
Soft, Sure-Grip Handles – These are ergonomically flared handles that are specifically aimed at minimizing fatigue for your body. The handles also fold down for compact storage.
Finger Controlled Throttle – Equates to wide-ranging speed control and effortless operation.
Tine Speed – The tines rotate at an acceptable 240 rpm…which is more than enough for even the toughest ground-breaking task.
Warranty – There is a 5 year warranty on the tiller…which includes the Honda engine. And, the special curved tines are so indestructible that Mantis gives a lifetime warranty for any tines that break…which isn’t very likely!
Kickstand – The kickstand is included to facilitate solid support when the engine is shut off and you’re taking a lemonade break from garden work…or gassing-up the tank.
Optional Attachments – There are some great extras that can be had that turn this tiller into a furrower, an aerator, a dethatcher, and edger, or a crevice cleaner. You can even purchase wheels for it. Although the kickstand works well, sometimes it is a little less stressful to wheel the tiller from place to place.
Disadvantages Of The Mantis 7940
About 30 Minutes For Assembly – Out of the box, there are a number of steps needed to put this tiller together. They are simple but, involve a bit more time than some other tiller – cultivators. This video gives a detailed description to make this an uncomplicated and straightforward experience:
Nuts Vibrating Loose – The nuts, especially the acorn nuts on the screw-on knobs, will eventually start to loosen up due to the machine’s vibration. TIP: Put a little Loctite on the bolts and…no problem anymore!
Tine Retaining Pin Issue – These pins get worn out over time, loosen up, and pop off. Mantis needs to replace these with a locking-type spring-loaded pin that will not jump off and get lost in the dirt. TIP: In the meantime, keep a few replacement retaining pins on hand because, eventually, you will need one or two.
Not Many Negatives…But A Whole Lot Of Positives!
You will not believe how easy this tiller gets into tight spaces and BOY, does it ever pulverize the dirt! There is nothing…NOTHING…that this super powerful workhorse won’t do!
If you want the best of both worlds…no mixing gas and oil…a tiller that can gobble a monster load of dirt and spit it out in a fine, loose texture…then, you want a Mantis 4-Cycle Tiller Cultivator 7940!
