If you're building a patio, or a deck, or a fence, or a garden, or doing yard work or planting a tree or moving your firewood into place for the winter, you've got heavy things to move...gravel, dirt, sand...maybe even stone. But most carts available for your riding mower today are built for moving mulch, leaves or sticks...they fall apart like a wet newspaper if you try anything more.  They have little or no control in dumping a load especially if you try to fill the tub more than half way or heavier loads.  They dump like a teeter-totter - when you unlatch the tub, any heavy load will shift, slide, and slam to the ground.  Or, one of the tires is flat.  So, you leave your rider in the shed and move the load yourself...or you try OxCart™.

OxCart™ was designed to do the heavy work. It's the only cart that is dynamically load-tested by a certified independent lab to move up to 750 pounds. Go ahead and fill it all the way with sand, gravel, dirt, stone, pavers or firewood. Now you'll need to move that heavy load across your well-groomed yard and gardens. No worries, the wider turf tires are the same ones found on most riders and designed to move effortlessly without leaving ruts. Costco Bonus: Free Run-Flat Tire Upgrade included - $50 Value!  These tires contain a non-hazardous polymer liquid that only hardens when exposed to air as it self-seals filling most punctures instantly before losing air in the tire!  No more flats that keep you from finishing projects on time!

Ready to dump?  You've got a new challenge - lifting that load in a safe and controlled way. Again, OxCart has you covered. OxCart™ is POWER-ASSISTED! The patent-pending power assisted lift reduces lift effort by up to 90%! Plus, the safer rear pivot design provides you 60% more control in dumping your bigger loads. And, OxCart has a side-dumping feature.  The tub rotates 110 degrees from either side allowing you to place that heavy load exactly where you need it, eliminating backing or the need to reposition the cart.  OxCart’s max strength, exclusive power-assisted lift, dump pivot point moved to the rear, and side dump features provide safer and max control at any angle so loads are dumped precisely where you want.

OxCart is more than just a strong cart; it's smart too! It assembles in minutes and will be a valued partner for years, helping you finish more projects in less time with less effort. Carry More. Lift Less. Get moving on those big projects!
