IMPIACT IMPLEMENTS® CAT-0/Cat 1 Disc Plow/Harrow. Prep Soil, Cut Weeds & Clear Crop Remains. Review

Overview

The IMPIACT IMPLEMENTS® CAT-0/Cat 1 Disc Plow/Harrow is not a lawn mower—it’s a heavy-duty ground engagement tool designed for small-scale farmers, homesteaders, and serious gardeners who need to prep soil, cut weeds, or clear crop remains. Priced at $599.99 with a solid 4.0-star rating from 86 reviews, this disc harrow bridges the gap between cheap, flimsy tractor attachments and commercial-grade equipment. It’s built for compact tractors and sub-compact utility tractors equipped with Category 0 or Category 1 three-point hitches.

Who Should Buy This

Small-acreage homesteaders – If you’re managing 1–5 acres of garden plots or pasture, this disc harrow gives you the ability to break up soil, incorporate cover crops, or prep seedbeds without renting a bigger tractor attachment.

Compact tractor owners – Owners of Kubota BX series, John Deere 1-series, or similar sub-compact tractors will appreciate the lightweight design (around 200–250 lbs) that won’t overwhelm your machine’s lift capacity.

Gardeners transitioning to tractor-based tillage – If you’ve been using a walk-behind tiller and want to speed up soil prep, this harrow lets you cover more ground faster, especially for larger vegetable plots or food plots.

Budget-conscious farmers – At $600, this is one of the most affordable disc harrows on the market. It’s a good entry point for those who need a functional tool but can’t justify spending $1,200+ on a heavier unit.

Key Features Breakdown

Category 0 and Category 1 hitch compatibility – This is a big deal. Most budget harrows only fit Cat 1, but the IMPIACT model includes adjustable hitch pins that work with Cat 0 (common on older or smaller tractors) and Cat 1 (standard on sub-compacts and compacts). That flexibility saves you from buying adapter bushings.

Adjustable gang angle – The disc gangs can be angled to control how aggressively the harrow digs into the soil. A steeper angle cuts deeper for primary tillage; a shallower angle works better for smoothing or light weed control. This adjustability is essential for tackling different soil conditions.

Heat-treated steel discs – The discs are made from heat-treated boron steel, which resists bending or chipping when you hit rocks or roots. Cheaper harrows often use mild steel that dulls quickly or warps under stress.

Transport wheels (optional) – While not standard, the frame is designed to accept transport wheels, which makes moving the harrow across paved surfaces or between fields much easier. Without wheels, the discs will scrape and wear on pavement.

Compact footprint – The unit is roughly 48–54 inches wide, making it easy to store in a garage or shed. It’s also light enough to maneuver by hand when disconnected from the tractor.

Pros

Exceptional value for the price – At $599, you’re getting a functional disc harrow that costs half as much as comparable models from brands like King Kutter or Tarter. It won’t last forever under heavy use, but for light-to-moderate duty, it’s a steal.

Works with smaller tractors – Many disc harrows require at least 20–25 PTO horsepower. This one can be pulled by tractors as small as 15–20 HP, thanks to its lighter weight and adjustable gang angle.

Easy to assemble – Most buyers report assembly in under an hour with basic hand tools. The hitch bracket and disc gangs bolt together straightforwardly, and the instructions are clear enough for a DIYer.

Solid build for the money – The heat-treated discs and reinforced frame hold up well against sandy or loamy soils. It won’t crumble after a season of light use.

Versatile adjustments – You can set the gang angle to match the job—shallow for weeding or deep for breaking new ground. That versatility makes it more useful than a fixed-angle harrow.

Good customer support – IMPIACT has a reputation for responding to questions and replacing damaged parts quickly, which is rare in the budget implement space.

Cons

Not for heavy clay or rocky soil – The discs are tough, but they’re not heavy enough to penetrate hard-packed clay or rocky ground without multiple passes. If your soil is dense, you’ll need to make several passes or wet the ground first.

No transport wheels included – You’ll need to buy or fabricate your own transport wheels if you want to move the harrow on pavement. Dragging it across concrete will wear the discs prematurely.

Paint quality is mediocre – Several users report rust forming on the frame and discs after a few months, especially if stored outdoors. A coat of rust-resistant paint or oiling the discs after use helps, but it’s an extra step.

Not for large-scale farming – This harrow is built for small acreage and hobby farms. If you’re trying to prep 20+ acres annually, the frame and bearings will wear out faster than a heavier commercial unit.

Bottom Line

The IMPIACT IMPLEMENTS CAT-0/Cat 1 Disc Plow/Harrow is a smart buy for compact tractor owners who need an affordable way to prep garden plots, manage weeds, or clear crop residue on small acreage. It’s not a heavy-duty commercial tool, but for the price, it delivers solid performance for light-to-moderate use. If you own a sub-compact tractor and have 1–5 acres of ground to work, this harrow will save you time and money compared to renting equipment or relying on a walk-behind tiller. Just plan to store it indoors and expect to make multiple passes in tough soil. I’d recommend it confidently to budget-conscious homesteaders and gardeners.

Frequently Asked Questions

Will this fit a Kubota BX2380 or John Deere 1025R?
Yes, both tractors have Category 1 hitches, and the IMPIACT harrow includes adjustable pins that fit Cat 1 perfectly. You may need to check your tractor’s lift capacity—most BX and 1-series models can handle the weight easily.

Can I use this to break up new ground with heavy sod?
It can, but you’ll need to make several passes with the gangs set at a steep angle. For thick sod, it’s best to mow or brush-hog the area first, then harrow. Wetting the ground also helps the discs cut through.

How do I adjust the gang angle?
The frame has a series of holes and a locking pin. Loosen the pin, rotate the gang assembly to the desired angle (steeper for deeper cut), then reinsert the pin. It’s a simple process that takes about a minute once you’ve done it a couple of times.
