About this product
📘 Overview
The Star Industries UT31 is a high capacity skid steer bucket built for loose material — the deeper utility profile carries 17 to 24.2 cubic feet heaped, noticeably more than a low-profile dirt bucket of the same width. Seven widths are offered from 60 to 84 inches, and each can be ordered plain, with bolt-on teeth, or with a bolt-on blade. Construction is extra heavy-duty steel with fully welded seams inside and out, a reinforced hat section across the top, steel side blades, and a 3/8 inch plate universal quick-tach sized for current high-flow skid steer loaders.

🔑 Why Buyers Choose the Star Industries UT31 Utility Bucket
- The utility profile carries more than a dirt bucket at the same width — a 72 inch UT31 holds 20.6 cu ft heaped against 18.0 cu ft for the 72 inch low-profile dirt bucket, so the same doorway width moves 14 percent more mulch, grain or snow per pass.
- The bolt-on blade takes the wear instead of the bucket lip — a reversible 5/8 inch x 8 inch blade gives roughly three times the edge life and unbolts when spent, and flipping it once doubles the interval again before replacement.
- Teeth and blade are a choice, not a bundle — order the UT31 plain for snow and grain where a smooth edge scrapes clean, with teeth for frost and compacted soil, or with the bolt-on blade for abrasive material.
- Scuff bars protect the panel that wears first — three to five 1/2 inch x 3 inch bars across the bucket bottom take the abrasion from dragging and back-dragging, which is where an unprotected shell thins and eventually splits.
- 3/8 inch plate quick-tach is sized for current machines — modern skid steers put far more breakout force through the coupler than the machines these buckets were originally designed against, and the heavier plate is what keeps the mount from working loose.

A bolt-on blade adds the suffix BOB and is a reversible 5/8 inch x 8 inch double-bevel blade supplied with fasteners: BOB60, BOB66, BOB72, BOB78 and BOB84 by width. Bolt-on side cutters, part LP-SC, are sold as a pair. Replacement teeth parts are available individually — tooth PBTA8023, shank adapter PBT1001 and flex pin PBTRP.
🚜 Which Skid Steers Fit the UT31 Utility Bucket?
The UT31 mounts with a universal quick-tach plate made from 3/8 inch steel, which is the standard skid steer coupler interface. Star builds the bucket profile to suit your specific make and model, so give them at checkout. It fits skid steer loaders and compact track loaders running a universal quick attach coupler from Bobcat, Caterpillar, John Deere, Case, New Holland, Takeuchi, Kubota, Gehl and other makers using the same standard. No auxiliary hydraulics are needed. Match bucket width to your machine rather than to the widest option: a bucket wider than the tyre or track stance loads the coupler unevenly when working one corner. Confirm your machine carries a universal quick attach coupler rather than a proprietary mount before ordering.

Skid steer utility bucket or low profile dirt bucket — which do I need?
The Star Industries UT31 utility bucket has a deeper, taller profile than the LP22A low-profile dirt bucket, so it holds more loose material at the same width — 20.6 cu ft against 18.0 cu ft at 72 inches. The low-profile design gives better visibility of the leading edge for grading and back-dragging; the utility profile moves more volume per pass. Choose the utility bucket for mulch, grain, snow and light material, and the low-profile for dirt work.
Which UT31 bucket width should I order?
The UT31 comes in 60, 66, 68, 72, 78, 80 and 84 inch widths. Match the width to your machine rather than picking the largest: a bucket significantly wider than the tyre or track stance puts uneven load through the coupler when digging one corner. As a rule the bucket should be at least as wide as the machine so it clears a path for the tracks.
Do I want a skid steer bucket with teeth or a bolt on blade bucket?
Teeth suit frost, compacted soil and material that needs breaking before it will load. A bolt-on blade suits abrasive material and any work where a clean edge matters, and gives roughly three times the edge life. A plain edge is best for snow and grain where teeth would leave material behind. Teeth add the suffix T to the model, and a blade adds BOB.
How many teeth come on a UT31 bucket?
Tooth count is set by bucket width: 7 teeth on the 60 inch, 8 on the 66 and 72 inch, 9 on the 78 inch and 10 on the 84 inch. They are pin-on series 23 teeth measuring 2 1/4 inches across the point, and the individual tooth, shank adapter and flex pin are all available separately as replacements.
Can I add a bolt-on blade to a bucket I already own?
Yes. The bolt-on blade is ordered by bucket width as BOB60, BOB66, BOB72, BOB78 or BOB84, is a 5/8 inch by 8 inch double-bevel blade, and includes the fasteners. It is reversible, so flipping it when one edge wears doubles the interval before replacement.
Does the UT31 bucket need auxiliary hydraulics?
No. The Star Industries UT31 utility bucket is a non-hydraulic attachment. It mounts on the universal quick attach coupler and needs no hydraulic connection, so any skid steer or compact track loader with a standard quick-tach plate can run it.
What protects the bottom of the bucket from wear?
The UT31 carries heavy 1/2 inch by 3 inch scuff bars across the bucket bottom, three to five of them depending on width, plus steel side blades protecting the sides and a reinforced hat section across the top. The leading edge is beveled hard carbon steel punched blade, and optional side cutters, part LP-SC, protect the corners.
Is the UT31 covered by a warranty?
The Star Industries UT31 utility bucket carries a 5-year factory guarantee and is made in the USA. Star Industries has been manufacturing attachments in the United States since 1981.
Can I buy replacement teeth separately?
Yes. The replacement tooth is part PBTA8023, the shank adapter is PBT1001 and the flex pin is PBTRP, all sold individually so a single worn tooth does not mean a new edge.
Are side cutters available for the UT31?
Yes. Bolt-on side cutters, part LP-SC, are sold as a pair and protect the bucket corners, which are the first areas to wear when working against a wall or trench face.
Are Star skid steer buckets universal, or built to my machine?
Both apply. The mount is the standard universal quick attach coupler, so it fits any skid steer or compact track loader using that interface. But Star notes that different loaders need different bucket profiles to work properly, and builds each bucket to match your specific make and model. Enter your machine make and model at checkout and eskidsteer passes them to Star with the order.
