The Parma Arena Groomer®
The Parma Arena Groomerhas been proven in arenas and on tracks for all events that require good footing. Its ability to prepare your base as well as the top surface in one pass can improve the performance of your horse and save stress on his legs at the same time. The unit uses vibrating "S"-tines that can be set to your desired digging depth to leave a well-prepared base. Following the tines is a leveling bar that will shave off high spots and carry dirt to fill holes as you pass over the arena. To the rear of the machine is a roller that conditions the surface and also gauges the depth of the tines to leave a uniform finish on your arena.
What does the Parma Arena Groomer® Do?
The 'S' Tines loosen compacted soil and prepare the base. Front depth is controlled by the hydraulic lift of the tractors 3-point hitch in combination with the set depth of the rear roller. The tines have reversible points that are also replaceable. The Leveling Bar fills in holes and smoothes humps. It adjusts to different depths to control the amount of surface material carried.The Rear Pipe Roller, which is fully adjustable also, breaks and pulverizes clods. It firms and packs the base, leaving a soft, uniform surface.

How is the Parma Arena Groomer® Different From Other Drags?
The Parma Arena Groomer utilizes the balance of three functions placed in one unit to create a complete ground preparation in one pass. The Arena Groomer uses time proven seedbed preparation techniques, applied in a design exclusively for the Arena. The combination of the S-Tines, leveling bar, and rear pipe roller and their placement create that perfect balance. There is no need to own two or three different tools to accomplish the same task that one Parma Arena Groomer will do.
How Do I Know What Size Is For Me?
There are three standard sizes of the Arena Groomer; the 8-foot 3Bar, which has three rows of S-Tines, and the Mini 6 foot and 5 foot, which each, have two rows of smaller, mini S-Tines. The size determination is mostly dependant on the size of tractor or power unit available to pull it. The 8-foot model will require 30 to 35 horsepower minimum, while the mini models will need only 18 to 25 horsepower min. Remember to also match the width of the Arena Groomer with the tractor tire outside width to insure coverage of the tractor tire tracks. We have been very successful utilizing four wheel ATV's with the 5-foot model.
There is available a pull tongue option for those without a 3-point hitch hook up on their power unit. Other widths are available upon special order.
All of the above mentioned models attach to the tractor utilizing the 3-Point hitch for quick and easy hook-up and go. They are lightweight with the 8-foot unit weighing just 800 lbs while the lighter mini models are just 300 to 350 lbs. With all these features each unit is easily adjusted and maintained by anyone around the arena.

What Do Parma Arena Groomer® Owners Say About Parma?
The Arena Groomer prevented a huge wreck at the Idaho Qualifier after a forgotten hose flooded 1/3 of the arena overnight. With the Arena Groomer we moved the mud around the arena and worked it into the dry ground. We started on time and roped all day with no problems.

What makes the Parma Arena Groomer® a true three-in-one tool?
Most arena maintenance routines demand three separate passes — one to rip the compacted base, one to level the footing, and one to firm and finish the surface. The Parma Arena Groomer® collapses all three jobs into a single pass behind one tractor or ATV. As the unit travels, the curved S-tines loosen the soil, the adjustable leveling bar shaves off high spots and carries that material into the low ones, and the rear pipe roller breaks up clods and leaves a semi-compacted, "fluffed" finish. The result is consistent, cushioned footing without the time and fuel cost of multiple implements.

How does each working component do its job?
The groomer works in three stages, front to back. The S-tines unearth and plow the arena material; their curvature applies minimal top pressure so they break up the surface rather than gouging it, and the reversible, replaceable chisel points let you flip or swap them as they wear. The adjustable smoothing (leveling) bar then knocks down the high spots and fills in the valleys the tines create. Finally the rear pipe roller breaks apart remaining clods, firms the base, and also gauges tine depth so the cut stays uniform across the whole arena.

Which sizes and models can you choose from?
Parma offers over ten sizes and models, grouped into Mini, Standard, and Professional lines. The Mini series — AG513 (5 ft), AG615 (6 ft), AG719 (7 ft), and the AG821M (8 ft mini) — is built for smaller tractors and ATVs/UTVs in the 18–30 HP range. The Standard series — AG821 (8 ft), AG1027 (10 ft), and AG1233 (12 ft) — handles larger arenas and tractors in the 30–60 HP range. The model numbers encode the working width and tine count: the AG513 spans 5 feet with 13 S-tines, the AG821 spans 8 feet with 21 S-tines, and so on up the line.

What about the AG PRO professional groomer?
For commercial barns, training facilities, and competition tracks that demand the deepest, most uniform conditioning, Parma builds the 8 ft AG PRO. It pairs dual rows of working tines — an S-tine row plus a coil-tine row — so the base and the top surface are prepared together in a single pass. This is the unit Parma points serious operators toward when arena footing quality directly affects horse performance and leg health.
What add-ons and options fit the groomer?
Parma offers a range of parts and add-ons so the groomer adapts to your footing and your tow vehicle. Options include a coil-tine conversion for synthetic and fiber-blend arenas, a solid roller in place of the standard pipe roller, a tongue-and-ratchet-jack setup for pulling behind an ATV or UTV, and a swivel hitch for three-point tractor attachment. Reversible, replaceable S-tine points are standard wear items, and during 2026 Parma is offering free shipping on all Arena Groomer parts with code FreeShip2026.

How do I know which size is right for my arena?
Size selection is mostly driven by the tractor or power unit available. The 8-foot model needs 30 to 35 horsepower minimum; the mini models need only 18 to 25 horsepower. Match the width of the Arena Groomer to the tractor's tire outside width to ensure coverage of the tractor tire tracks. The 5-foot model has been used successfully behind four-wheel ATVs.
How much do the units weigh and how do they attach?
The 8-foot unit weighs about 800 lbs, and the lighter mini models weigh just 300 to 350 lbs. All standard models attach to the tractor utilizing the 3-point hitch for quick hook-up. A pull-tongue option is available for power units without a 3-point hitch hookup.
How are the S-tines and roller adjustable?
Front depth is controlled by the hydraulic lift of the tractor's 3-point hitch in combination with the set depth of the rear roller. The tines have reversible points that are also replaceable. The leveling bar adjusts to different depths to control the amount of surface material carried. The rear pipe roller is fully adjustable as well.
Is the Parma Arena Groomer® easy to assemble?
Yes. The Parma Arena Groomer ships easily by truck in a simple bolt-together package that requires only a ¾ wrench for assembly. The mini Arena Groomers need just minimal assembly. The Parma Company has dealers established around the country to help with the buying process.
How do I order a Parma Arena Groomer®?
Call Parma Company's helpful staff at 208-722-5116 or email [email protected]. The company is located at P.O. Box 190 / 107 Main Street, Parma, Idaho 83660 — in the heart of the Treasure Valley of southwest Idaho and eastern Oregon.
What does the Parma Arena Groomer® actually do?
It performs three ground-preparation jobs in one pass behind a tractor or ATV. The S-tines loosen and plow the arena soil, the adjustable leveling bar fills holes and shaves humps, and the rear pipe roller breaks clods and leaves a semi-compacted, fluffed finish. The aim is consistent, cushioned footing that protects horse legs and improves performance.
How does the Arena Groomer work, step by step?
Front to back, the curved S-tines unearth and rip the arena material with minimal top pressure so they break it up rather than dig craters. The adjustable smoothing bar then knocks down the high spots and fills the low ones. The rear pipe roller breaks apart remaining clods, firms the base, and gauges tine depth so the cut stays even across the entire arena.
What do the model numbers like AG513 and AG821 mean?
The model numbers encode the working width and the number of S-tines. The AG513 is 5 feet wide with 13 S-tines, the AG615 is 6 feet with 15 tines, the AG719 is 7 feet with 19 tines, and the AG821 is 8 feet with 21 S-tines. The larger Standard models follow the same pattern up to the 12-foot AG1233.
How much does a Parma Arena Groomer cost?
On the 2026 retail price list, the Mini models start at $2,650.00 for the AG513, $2,850.00 for the AG615, $3,050.00 for the AG719, and $3,250.00 for the AG821M. The Standard models run $4,875.00 (AG821), $5,475.00 (AG1027), and $6,275.00 (AG1233). The professional AG PRO is $8,500.00. Confirm current pricing with Parma, as prices are subject to change.
What tractor or ATV horsepower do I need?
The Mini series is designed for smaller tractors and ATVs/UTVs in roughly the 18–30 HP range, with the AG513 specified for 18–25 HP. The Standard series suits larger machines in the 30–60 HP range. Parma can match a model to your specific tow vehicle and tire width, so it is worth a quick call to 208.722.5116 before ordering.
Can I pull the groomer behind an ATV or UTV instead of a tractor?
Yes. The Mini models are sized for ATV/UTV duty, and Parma offers a tongue-and-ratchet-jack add-on configured for pulling behind an ATV or UTV. For three-point tractor hookup, there is a swivel hitch option. Tell Parma what you will be towing with and they will spec the right hitch setup.
Will it work on synthetic or fiber-blend footing, not just sand and dirt?
Yes. Parma offers a coil-tine conversion designed for synthetic and blended arena surfaces, which work that type of footing more gently than the standard S-tines. The professional AG PRO actually combines an S-tine row and a coil-tine row so it handles a wide range of footing in one pass.
What is the AG PRO and who is it for?
The AG PRO is Parma's 8-foot professional groomer built with dual tine rows — an S-tine row plus a coil-tine row — so it prepares the base and the top surface together. It is aimed at commercial barns, training facilities, and competition tracks where footing quality directly affects horse performance and leg health and where the groomer runs often.
Are the S-tine points replaceable when they wear out?
Yes. The S-tines use reversible, replaceable chisel points, so as the working edge wears you can flip the point to a fresh edge and, when both edges are spent, swap in a new point rather than replacing the whole tine. Replacement points and other wear parts are stocked as Arena Groomer Parts.
Can I adjust how deep the groomer cuts?
Yes. The S-tines have adjustable depth so you can set how aggressively the unit rips the footing, and the rear roller helps gauge that depth to keep the cut uniform. The leveling bar is also adjustable to control how much material it moves. This lets you do a light refresh between rides or a deep reconditioning pass as needed.
Who makes the Parma Arena Groomer?
It is made by the Parma Company, a century-old farm-equipment manufacturer located at 105 E. Main St., Parma, Idaho 83660, in the Treasure Valley of southwest Idaho and eastern Oregon. Parma is a long-established manufacturer of specialized agricultural equipment and developed the Arena Groomer line in 1994.
Why was the Arena Groomer originally developed?
Parma created the Arena Groomer® in 1994 to fill the need for an economical yet effective way to work and groom the footing in horse arenas. Rather than buying several separate implements, owners could maintain safe, consistent footing with a single tool. It has since been proven in arenas and on tracks for all events that require good footing.
How is the Arena Groomer different from a simple drag or harrow?
A basic drag or harrow mostly smooths the top surface. The Parma Arena Groomer prepares the base as well as the top in one pass — the S-tines work down into the compacted base, the leveling bar redistributes material, and the roller firms and finishes. That combination produces more uniform, cushioned footing that can reduce leg stress on horses.
How do I buy one, direct or through a dealer?
You can order direct from Parma or buy through their dealer network. Call 208.722.5116 (fax 208.722.6012) or email [email protected], and use the Arena Groomer Dealers locator at parmacompany.com to find a regional supplier. Operator manuals and the 2026 retail price list are also available on the site.
Is there a current promotion on parts?
Yes. During 2026 Parma is offering free shipping on all Arena Groomer parts when you use the code FreeShip2026 at checkout on parmacompany.com. This covers replacement S-tine points and other Arena Groomer Parts. Check the site for current terms, as promotions can change.
What's the easiest way to pick the right model for my arena?
Match the working width to your arena size and the model series to your tow vehicle: Mini models for smaller arenas and ATVs/UTVs or compact tractors, Standard models for larger arenas and bigger tractors, and the AG PRO for high-use commercial and competition settings. If you are unsure, call Parma at 208.722.5116 with your arena dimensions and tractor or ATV horsepower and they will recommend the right unit.
