The 18 " is to the tip of the rippers

These were a perfect fit for my Tractor Supply County Line 5-foot box scrape. The size appears to be a general fit for all. I've used these for the past two weeks and have no issues to report with them.

Appears to be good quality, Will find out in a couple days when I put these to task. For the negative, Someone does not know how to pack heavy objects for shipping . This box was no way meant for shipping something of this weight. ANNND here is what irritated me to no end. They used Styrofoam . Just enough to break up and have Styrofoam little balls all over my garage and me when I managed to unpack it. The pack of bolts and pins were busted open and a couple of them laying around in the foam. Lucky they did not make it out of the packing . Yes, Please learn to box heavy items.

Assembly was straightforward. The adjustable handles make it easy to use for different tasks. The plow teeth are also replaceable, which is a big plus.

Perfect for small and medium-sized plowing tasks. It’s easy to adjust, and the steel construction is rugged. It’s a great addition to my tractor toolkit.

The Box Blade is incredibly well-built. The heavy-duty steel construction ensures durability, and the powder coating helps keep it rust-free. Very happy with my purchase.

I’ve used this on some very tough soil, and it works great! The ripper shanks help break through tough ground, and the box blade digs deep.

I love the adjustable handle and plow teeth. The holes make it simple to fine-tune, and the blade works great for a variety of jobs like grass leveling and digging.

Great tool for leveling and tilling soil. The adjustability of the plow teeth is very convenient, and it fits perfectly on my tractor.

Used it for plowing a field and it performed excellently. The height and spacing of the ripper shanks worked great for my needs.
