Bobcat S740 Attachments Buyer Guide — What to Look For

Bobcat S740 attachments bolt onto one of the most capable mid-frame skid steers on the market — but only if you match five factors before you buy. Those factors are mount interface type, hydraulic flow and pressure ratings, rated operating capacity versus attachment weight, overall machine dimensions for clearance, and the specific task demands of your operation. Get one wrong and you're stuck with an expensive mismatch. This guide gives you the exact specs, price benchmarks, red flags, and questions that eliminate guesswork and put the right attachment on your machine the first time.

What Specifications Should You Verify Before Buying Bobcat S740 Attachments?

Bobcat S740 attachment purchases require verification of 3 critical specification categories: mounting compatibility, hydraulic requirements, and weight limits. These technical parameters determine operational safety and prevent costly compatibility issues across mounting systems, flow rates, and capacity ratings.

What Mounting System Compatibility Must Match?

The Bobcat S740 uses the Bob-Tach mounting interface as its standard coupler. Any attachment with a universal skid steer quick-attach plate (also called the standard ISO 24410 interface) connects directly. Attachments built for a different proprietary mount require an adapter plate, which adds 150 to 300 pounds and reduces breakout force by 5 to 12 percent.

• Mount interface: standard quick-attach (Bob-Tach compatible) — a non-standard mount prevents direct connection and requires a $200–$600 adapter
• Coupler pin spacing: 2-inch pin diameter with centers at approximately 16.5 inches apart — mismatched pin spacing causes the attachment to sit loose and creates a safety hazard under load
• Attachment plate width: verify the plate measures approximately 46 inches wide — an oversized plate contacts the loader arm frame and prevents full curl

What Hydraulic Flow and Pressure Specs Must You Confirm?

The S740 delivers standard hydraulic flow of 23.2 GPM at 3,350 PSI. The optional high-flow package increases output to 30.5 GPM. Attachments requiring more than 23.2 GPM — such as forestry mulchers and high-output augers — do not function at rated speed on a standard-flow S740. Running a high-demand attachment on insufficient flow causes motor stalling, overheating, and premature seal failure.

• Standard-flow attachments: require 10–23 GPM — compatible with all S740 units
• High-flow attachments: require 24–30 GPM — compatible only with S740 units equipped with the high-flow hydraulic option
• Hydraulic pressure rating: attachment motor must be rated for a minimum of 3,000 PSI — motors rated below this threshold wear prematurely under the S740's 3,350 PSI output

What Weight and Capacity Specs Determine Safe Operation?

The S740 carries a rated operating capacity of 2,690 pounds at 50 percent tipping load. Every attachment's total weight — plus the material it holds — must stay below that figure. A 72-inch grapple bucket weighing 850 pounds leaves 1,840 pounds of material capacity. Exceeding rated operating capacity causes rear-axle lift, loss of steering control, and accelerated wear on the loader arm pivot pins.

• Attachment dead weight: verify weight is listed in the spec sheet — subtract from 2,690 lbs to determine remaining material capacity
• Combined load center: keep within 24 inches of the attachment plate face — loads extending beyond 36 inches from the plate reduce effective capacity by 15–25 percent
• Machine tip load: 5,380 lbs total — never operate above 50 percent of tip load on flat ground, 40 percent on slopes exceeding 10 degrees

What Do Different Bobcat S740 Attachment Price Tiers Offer?

Bobcat S740 attachment pricing follows 3 distinct tiers with varying build quality, specification levels, and feature sets. Price differences reflect changes in construction materials, hydraulic capabilities, and operational specifications that determine long-term durability and performance capacity.

What Do You Get at Each Price Level?

Bobcat S740 attachments fall into three price tiers spanning $400 to $12,000+, depending on attachment type. The ranges below represent the most common categories — grapples, pallet forks, buckets, and augers.

• Entry-level ($400–$1,800): 3/16-inch plate steel, imported cylinders, pin-on hoses, limited or no warranty beyond 90 days — suits farm owners and landowners using attachments fewer than 15 hours per month on non-abrasive material
• Mid-range ($1,800–$4,500): 1/4-inch plate steel, domestic-spec cylinders with hardened chrome rods, bolt-on cutting edges, 12-month structural warranty — suits landscapers and contractors running 15–40 hours per month across mixed conditions
• Professional ($4,500–$12,000+): 3/8-inch plate steel on high-stress points, AR400 wear surfaces, Parker or equivalent hydraulic motors, continuous-duty rated cylinders, 24-month structural warranty — suits tree service professionals, demolition contractors, and daily-use commercial operations exceeding 40 hours per month

What Specifications Change at Each Tier?

Steel thickness accounts for the largest performance gap between entry-level and professional attachments. Entry-level grapples use 3/16-inch (0.1875-inch) mild steel; professional grapples use 3/8-inch (0.375-inch) plate with AR400 abrasion-resistant steel on tine tips. Cylinder bore diameter increases from 2 inches at entry level to 3 inches or larger at professional tier, directly raising clamp force from roughly 3,000 lbs to 6,500+ lbs.

When Is Entry-Level Sufficient?

Entry-level attachments perform acceptably at fewer than 15 operating hours per month in light-duty material. Moving loose brush, handling dry hay bales, or grading topsoil with a standard bucket falls within entry-level capacity. Once monthly hours exceed 15, or the material includes rock, stumps, or wet hardwood, upgrade to mid-range to avoid cracked welds and bent tines within the first season.

What Should You Avoid When Buying Bobcat S740 Attachments?

Bobcat S740 attachment purchases fail due to 3 common buyer mistakes: ignoring product red flags, accepting inflated specifications, and overlooking warranty terms. These oversights result in compatibility problems, performance shortfalls, and inadequate coverage for equipment failures or defects.

What Are the Red Flags in Listings and Products?

Missing steel thickness specs are the single most common red flag in attachment listings. A manufacturer confident in build quality publishes exact material gauges. Listings that omit this data almost always use thinner steel than the buyer expects.

• No steel gauge listed: indicates 3/16-inch or thinner mild steel — ask for exact thickness before purchasing
• Hydraulic hoses included but no fitting size specified: signals generic imported hose assemblies that leak at operating pressures above 2,500 PSI — require #8 JIC or #10 JIC fitting specs
• Weight not published: prevents the buyer from calculating remaining machine capacity — a quality attachment always has a published weight accurate to within 5 percent
• "Universal fit" with no mount dimensions: a vague claim that does not confirm pin diameter, pin center spacing, or plate width — demand a dimensional drawing showing all three

What Specifications Are Frequently Overstated?

Grapple clamp force is the most commonly inflated specification in attachment listings. Sellers calculate theoretical force at the cylinder rod, not at the tine tip. Actual clamp force at the tine tip is 30–45 percent lower than cylinder rod force due to mechanical advantage loss through the linkage. Request tine-tip clamp force specifically, or calculate it by dividing the published cylinder force by the linkage ratio (typically 2.2:1 to 2.8:1).

What Warranty Terms Should You Verify?

Require a minimum 12-month structural warranty on any attachment priced above $1,500. Structural welds and frame integrity carry the highest repair cost. Hydraulic components — cylinders, hoses, and motors — require separate coverage because they fail differently than steel frames.

• Structural welds: minimum coverage 12 months — anything less than 12 months signals low confidence in weld quality
• Hydraulic cylinders and motors: minimum coverage 12 months — seal kits and rod scoring are the most frequent failure points
• Wear parts (cutting edges, tine tips, teeth): typically excluded from warranty — budget $150–$500 annually for replacement

How Do You Match Bobcat S740 Attachments to Your Situation?

Proper Bobcat S740 attachment selection requires systematic evaluation of 3 factors: operational requirements, equipment sizing, and specification verification. This matching process involves capacity analysis, application assessment, and comprehensive checklist completion before finalizing purchase decisions.

How Do You Determine the Right Attachment Size?

Match attachment width to the task footprint and machine capacity, not to the widest option available. A 72-inch grapple on an S740 handles most land-clearing and brush work. A 78-inch or 84-inch grapple exceeds the machine's optimal load center and reduces effective capacity by 10–20 percent at full extension.

• If clearing brush and small timber (under 8-inch diameter): choose a 66–72-inch root grapple with 3-inch tine spacing
• If handling palletized material or baled hay: choose 48-inch skid steer pallet forks rated to 4,000 lbs minimum with a 42-inch fork length
• If performing site grading or backfill: choose a 72-inch low-profile bucket at 0.5–0.75 cubic yard capacity

What Questions Should You Ask Before Purchasing?

Five questions expose attachment quality that product photos and spec sheets do not reveal. Most sellers only volunteer surface-level specs. These questions force disclosure of construction details that separate a two-season attachment from a ten-season one.

• "What is the exact steel thickness on the frame, tines, and mounting plate?" — reveals whether the manufacturer uses consistent gauge throughout or thin plate on hidden surfaces
• "What is the cylinder bore diameter and rod diameter, and are the rods hardened chrome?" — reveals hydraulic component grade; unhardened rods pit and leak within 200 operating hours
• "Is the attachment rated for standard-flow (23 GPM) or high-flow (30+ GPM) hydraulic systems?" — confirms immediate compatibility with the S740's hydraulic output
• "What is the total attachment weight as shipped, including mounting plate and hoses?" — reveals true dead weight for accurate capacity calculation
• "Does the structural warranty cover weld failure, and is there a separate hydraulic component warranty?" — reveals whether the seller stands behind both the steel and the hydraulic system independently

What Is the Complete Pre-Purchase Specification Checklist?

Verify all 10 specifications below before committing to any Bobcat S740 attachment purchase.

• Mount type: standard quick-attach, Bob-Tach compatible, with 2-inch pin diameter
• Attachment plate width: approximately 46 inches — confirm dimensional drawing
• Hydraulic flow requirement: 10–23 GPM for standard; 24–30 GPM requires high-flow option
• Hydraulic pressure rating: minimum 3,000 PSI on all motors and cylinders
• Total attachment weight: subtract from 2,690 lbs rated operating capacity
• Steel thickness: minimum 1/4-inch on frame and mounting plate for mid-range use
• Cylinder bore and rod diameter: minimum 2.5-inch bore for attachments over 66 inches wide
• Hose fitting size and type: #8 JIC or #10 JIC — confirm before ordering
• Structural warranty: minimum 12 months on welds and frame
• Overall attachment dimensions: confirm width, height, and depth do not interfere with loader arm travel at full dump and full curl

What Are the Most Popular Bobcat S740 Attachment Types?

Bobcat S740 operators most frequently purchase 5 attachment categories with varying hydraulic requirements and flow specifications. Demand patterns show clear preferences for specific attachment types, with some requiring high-flow hydraulic upgrades while others operate on standard flow systems.

Which Attachments See the Highest Demand for This Machine?

Skid steer grapples — both root grapples and standard grapples — rank as the most purchased attachment category for the S740. The machine's 2,690-lb rated capacity and 74.3-hp engine handle 66–72-inch grapples at full efficiency. Pallet forks rank second, followed by buckets, augers, and brush cutters.

What Hydraulic Attachments Require the High-Flow Option?

Forestry mulchers, high-output augers (above 18-inch bit diameter), and cold planers require the 30.5 GPM high-flow package. Running these attachments on the standard 23.2 GPM system results in 25–40 percent reduced RPM on the attachment motor. Trenchers, standard augers (up to 18-inch bit), and brush cutters rated under 23 GPM operate on the standard hydraulic system without modification.

What Standard-Flow Attachments Work Without Upgrades?

Grapples, pallet forks, buckets, snow pushers, bale spears, dozer blades, and backhoe attachments all operate on the S740's standard 23.2 GPM flow. These attachments use single-acting or dual-acting cylinders with low flow demand. Log splitters and stump grinders vary — verify the exact GPM requirement on the spec sheet. Any attachment listing "standard flow compatible" without a GPM number warrants a direct inquiry to the seller.

Frequently Asked Questions About Buying Bobcat S740 Attachments

Bobcat S740 attachment buyers commonly ask 5 technical and financial questions covering compatibility, purchasing decisions, and ownership costs. These inquiries address mounting systems, used equipment considerations, warranty coverage, total cost analysis, and hydraulic verification procedures.

Will Any Standard Quick-Attach Plate Fit the Bobcat S740?

Yes — any attachment using the industry-standard quick-attach plate with 2-inch pins and approximately 16.5-inch pin centers connects to the S740's Bob-Tach coupler.

Confirm the plate dimensions before purchasing. Some manufacturers build plates 1–2 inches wider or narrower than standard. A plate that is too narrow sits loose and shifts under load. A plate that is too wide contacts the loader arms. Request a dimensional drawing showing pin diameter, pin center distance, and overall plate width. Attachments labeled "universal" without these measurements are not verified compatible until you see the numbers.

Is It Worth Buying Used Bobcat S740 Attachments?

Used attachments save 30–50 percent over new, but only if the structural welds, cylinder rods, and mounting plate are in verified condition.

Inspect three areas before buying used. Check all welds for cracks — especially where tines meet the frame on grapples and where the heel meets the mounting plate on buckets. Examine cylinder rods for scoring or pitting; any visible scoring means the seals are compromised. Measure pin hole diameter on the mounting plate — holes worn more than 1/16-inch beyond spec indicate excessive play and require rebushing at $100–$300 per pin.

What Warranty Coverage Is Standard for New Attachments?

A 12-month structural warranty is the baseline for any new attachment priced above $1,500.

Professional-grade attachments carry 24-month structural coverage. Verify whether hydraulic components — cylinders, hoses, and motors — fall under a separate warranty or are included in the structural coverage. Warranties that exclude "normal wear" without defining the term give the seller broad grounds to deny claims. Request a written definition of covered components and excluded wear items before purchase.

What Is the True Cost of Owning a Bobcat S740 Attachment Over Five Years?

Total five-year cost equals purchase price plus $300–$1,200 in maintenance, plus $150–$500 per year in wear-part replacement.

A $3,000 mid-range grapple costs approximately $4,500–$5,500 over five years. That total includes annual hydraulic hose inspection and replacement ($75–$200 per hose), cylinder seal kits every 500–800 hours ($80–$150 per cylinder), and tine or cutting edge replacement once every 12–18 months ($150–$400 per set). Entry-level attachments cost less upfront but reach the same five-year total due to higher maintenance frequency and earlier frame failure.

How Do You Verify Hydraulic Compatibility Before Purchasing?

Cross-reference the attachment's GPM and PSI requirements against the S740's spec sheet — 23.2 GPM standard, 30.5 GPM high-flow, 3,350 PSI.

Request the attachment hydraulic spec sheet directly from the seller. The document lists required flow rate (GPM), operating pressure (PSI), and fitting size. Match the fitting size to your machine's auxiliary hydraulic couplers — the S740 uses flat-face couplers. Attachments shipped with ISO 16028 flat-face fittings connect directly. Attachments shipped with AG-style pioneer fittings require $30–$80 adapter couplers. Browse the full range of skid steer attachments to compare hydraulic specs across categories.
