Performance

This is a sturdy motor with plenty of power from a KohlerXTX engine. That power filters down to the high-grip wheels, helping them handle all types of mowing conditions, including on damp to outright wet grass. The all-wheel drive traction means uneven terrain and tough mowing conditions are no big deal. It powers through those goofy-looking tufts of grass in your yard that are longer than the rest of the grass with ease, and it won’t scalp hole- or divot-laden areas that sometimes cause your mower to become lopsided as it moves over uneven terrain.

The cutting height of the mower ranges from a minimum of approximately less than an inch to a maximum of height of just over 4 inches. What that means for you is that you can select from a wide range of heights to suit your yard conditions.

Ease of Use

Sure, it would be nice to have push-button starting, but the Jonsered L4621 reliably starts up on the first pull thanks to an easy-start auto-choke system, and it’s easy to assemble. Get it out of the box, adjust your cutting height, add some oil and gas, and go to work.

But before you do that job, remember that you can adjust the handle to suit your height; you can experiment with the speed of the mower and select what pace you want through variable speed controls; and the quick height adjustment for nine cutting heights allows for mowing in lots of different conditions. You can even adjust the cutting height on the fly with the ease of an ergonomic handle. I should add that the soft-grip handle won’t callous up your hands or tire them out.

If you choose to bag, notice how the bag-through handle fits between the handlebars for super-simple removal. In addition, the collector handle on the bag provides a great grip when you turn it over to empty the clippings. As part of the bag, a “dust blocker bag” will prevent small particles from reaching your nose and making you sneeze every other minute. The nicely balanced bag is easy to empty, by the way, thanks to a wide opening.

When you’re finished for the day, fold over the handles and store this mower in a tight space of your choosing. The convenient handles also make transportation easier if you need to move the mower from A to B in your car or truck. However, if you just need to move the mower somewhere within your premises, the handle in front will allow you to easily lift up the mower and do that.

Cut Quality & Options

The L4621 has an amazing nine cutting-height adjustments to choose from, so you have lots of options during the season as conditions change. No matter what cutting height you select, the L4621 delivers a precise cut every time out, thanks to a high-tunnel cutting-deck design. Whether you’re bagging, mulching, or sending out grass via the mower’s discharge, you’ll appreciate the close-trim ability of this mower. The large rear wheels adeptly charge through the thickest of grass and weeds, and they’re great when you need to tilt the mower back from time to time. The wheels in general provide great maneuverability and seem durable.

The noticeably slim front portion of this mower makes it ideal for cutting along edges while leaving behind no uncut wheel tracks. If you choose to mulch, put on the mulch plug and watch how that, in combination with the blade, will shred grass to fine fertilizer. Rear discharge offers faster and more efficient mowing if that’s your thing.

Maintenance

There is a water-hose connection on the Jonsered L4621, which makes it much easier to clean the cutting deck, thus improving the cutting results and keeping the mower in excellent condition for days on end.

When emptying the bag, make sure to clear the chute of clippings. See the owner’s manual for all maintenance tips.

Note: Like lots of lawn mower owner manuals these days, this one has instructions that are written for numerous models, which some may find confusing. It’s understandable, given that some models with a choke are described, while some without a choke are also included. In addition, the manufacturer says oil changes aren’t needed, whereas it’s recommended in the manual to change it once a year or after every 25 hours of operation. Would be nice to get some clarity here.

Safety Features

The L4621 has a pull lever on the handle that must be engaged to mow. Beyond that, see the owner’s manual for all safety features.

Special Features

You know, when contemplating what makes this mower “special,” no one feature necessarily comes to mind. This is a mower that, frankly, has pretty much the entire package. On the one hand, you could view it as not having a boatload of bells and whistles. On the other hand, it does have many great features that do indeed make it an accessible, easy to use mower for many people. If you like simplicity, durability, and efficiency, you can’t go wrong with the L4621. Other great features include:

  • Ergonomic handle for total comfort during operation
  • Easy starting with no priming or choking necessary
  • Easy handle-height adjustment to fit the best mowing position
  • Rear-wheel drive offers great traction even when bagging
  • Large wheels for great maneuverability around obstacles
  • Water hose connection for cleaning cutting deck easier

Cost Effectiveness

Given its durability, reliability, and overall simplicity, the L4621 could be viewed as a cost-efficient mower that should last a long time. It doesn’t hurt that it’s easier to clean than some mowers thanks to the included water-hose connection that allows for easy cleaning of the deck. Throw in 3-in-1 mowing options that offer fertilization (mulching), rear discharge (efficiency), and bagging (cleanliness), and you’ve got yourself one great mower. At once no frill and highly functionable, the L4621 is worth the cost.
