This kit will require you to purchase a 500# hydraulic table from your local Harbor Freight.  This kit will require someone with OK mechanical ability and tools.  Please check the video for what will be required. 

This Potted Tree Gadgetry PT Bonsai Cart Kit is one of the only ways to have one of our hydraulic carts shipped that won't cost you an arm and a leg.  The kit includes everything you need to turn a Harbor Freight 500 pound table lift into a perfect bonsai hydraulic push cart.  This kit is built right here in Lancaster County, PA - Made In The USA and the quality shows.

Assembling the kit to the lift table is pretty simple and only a few tools are needed.  There is no need to drill holes, but drilling 2 holes will make the cart stronger and provide additional support.  

  • Big wheel kit bolts onto the current gray colored 500-lbs hydraulic lift table from Harbor Freight ONLY
  • Flat Free 10" wheels never need air and are a smoother ride over rough terrain with minimal bouncing.  These keep their shape and allow you to turn and navigate smoothly unlike air filled tires which flatten under load.
  • Castor style steering operates from the push handle end of the cart where the lifting and lowering controls are.
  • All functions of the original table cart remain.
  • Minimal tools needed for installation.
  • Kit is easily shipped by UPS or USPS
  • Included in the kit:
    •   - Four- Flat free wheels complete with bearings
    •   - Two - Fork and bearing mounts for the castors
    •   - One - Rear mounting bracket for the straight wheels
    •   - All mounting hardware

Please Note:  The video below explains there are 2 different kits.  This has now changed and they are universal. You can see the general instructions to assemble below, but please refer to included instructions for the new kits.

Please check out this video to see what is involved.

Please Note:  This is a flat free tire and bearings kit - the hydraulic table is NOT included.  You can pick up the cart at Harbor Freight.  Be sure to use the Harbor Freight 20% (they seemed to stop providing these in 2021) coupons available online and via mail to save you some $$$$.

Wheels went on as stated on video. Could not be happier! Great product

Zach Lane

I’m pleased with the product itself, but I’m very dissatisfied with the description of the product online. The online description clearly states that the kit ONLY fits the 500 lb harbor freight cart. I did not watch the instructional video until after the kit arrived. While watching the video I was informed that I can specify if I want a kit that fits the 500 lb cart OR the 1000 lb cart. I would have much preferred to have a 1000 lb cart because the table length in longer than the 500 lb cart table length.
After unboxing the kit I learned that you guys updated the kit so that it universally fits either the 500 lb or the 1000 lb. This is not specified anywhere on your website (that I can clearly see) and it is not specified in the video.
Next, the video does not describe how to install the updated universal kit.
Lastly, the video described that all the nuts and bolts for the kit are loosened and tightened with a 9/16 socket. It took a variety of different sized sockets and wrenches to assemble the updated kit.
Again, I’m satisfied with the kit, but I’m very unhappy that I’m now stuck with a 500 lb cart because your website failed to mention that I had an option of getting the 1000 lb cart. I would have much preferred to have the 1000 lb cart.
Hopefully Harbor Freight will accept a refund for an assembled cart.

Thank you for the order. I am glad you like the kit.

While there is a 1000 pound version that can be custom ordered, we don't sell it.
The kit was also updated to be universal as you stated, but that has nothing to do with the 500 or 1000 lb cart. The universal kit means it will work on all versions of the Harbor Freight 500 pound table (the rectangle and the triangle brackets).
Thanks again for the order and providing your review. This gives us a chance to make things more clear for future customers.

Great idea, could be better

Love my new cart, and the conversion was easy. The only thing is I sure wish it was a kit that had the wagon handle like the one you sell. But for what the kit does, it does well. Thanks.

worth the $

A bit pricey but well worth it - they make the cart work really well
