Skid Steer Dual Side Flow Bucket - Top Dog Attachments

📘 Overview

This skid steer side discharge bucket — the Top Dog Dual Side Flow Bucket — mounts on a universal quick attach plate and discharges material out either side through a belt conveyor, turning a skid steer into a placement and feeding tool. The operator rotates and lowers the attachment to scoop, then rotates and raises it to become a spreader — flow direction and belt speed are both adjustable from dual control valves. Two build classes are offered and they are different machines: the heavy material versions (9000144, 9000145) run two belt motors, while the light material versions (9000144-72, 9000145-84) add a third motor driving a beater bar that prevents bridging in silage, feed and other light bulky material. All four run 15–20 GPM at 2,500 PSI.

A side discharge bucket occupies a narrow niche: it is a skid steer feeder bucket, a conveyor bucket attachment and a skid steer spreader bucket in one tool. Where a plain bucket dumps a heap you then have to spread, the belt places a metered ribbon exactly where you want it. As a material spreader attachment the light material models are the ones that handle silage and feed, because the beater bar is what stops bridging — the heavy models have no beater bar and will bridge on light bulky product.

⚙ Key Features of the Top Dog Attachments Dual Side Flow Bucket

• Discharges to either side — dual control valves select which side the belt runs to, so you place material without repositioning the machine.
• Adjustable belt speed — meter the discharge rate to the job — slow for precise placement, fast for spreading.
• Beater bar on light material models — a third orbit motor drives a beater bar that stops silage and feed bridging over the belt — the reason the light material version exists.
• 5/16" thick 2-ply asphalt belt — asphalt-grade belting survives abrasive material; a Chevron belt option is also available.
• Scoop and spread in one tool — rotate down to load, rotate up to discharge — no separate loader and spreader.
• 1" pillow block bearings, manually adjustable tensioners — belt tension is adjustable at four locations, so the belt can be trued rather than replaced when it drifts.
• Reaches where a spreader cannot — places material in barns, alleys and tight sites too small for a dedicated spreader or feeder truck.

🔑 Why Choose the Dual Side Flow Bucket?

• Feeds and places without repositioning — discharging either side means one pass down a feed alley does both sides of the barn.
• Light material models solve bridging — the beater bar keeps silage and feed moving onto the belt — without it, light bulky material arches over the opening and stops flowing.
• Meters the pour instead of dumping it — adjustable belt speed places a controlled ribbon of material rather than a heap you then have to spread.
• One machine covers loading and spreading — the same attachment scoops and discharges, so a skid steer replaces a loader plus a spreader on small operations.

🔗 What Is a Skid Steer Side Discharge Bucket Used For?

• Feeding silage and TMR down a barn alley
• Placing gravel and sand in tight access sites
• Backfilling trenches and along foundations
• Spreading topsoil and compost
• Bedding stalls and placing material where a spreader cannot reach

For barn feeding, measure your alley width against the 82"–97" overall widths before ordering — the bucket is wider than its nominal size.

🚜 Which Machines Fit the Dual Side Flow Bucket?

Compatible with skid steer loaders and compact track loaders equipped with a Universal Quick Attach (SSQA) system and an auxiliary hydraulic circuit, including:

Machine capacity: The side flow bucket weighs 1,000 to 1,350 lbs empty depending on width and material class. The host machine needs the rated operating capacity to carry that plus a full load out front.

The Dual Side Flow Bucket requires 15–20 GPM at 2,500 PSI to drive its belt motors. Most compact tractor loaders cannot supply this, so this attachment is specified for skid steers and compact track loaders. Compatibility is determined by mount type and available hydraulic flow, not by brand — confirm both your quick attach configuration and your machine’s flow and pressure rating before ordering.
