Bobcat Equipment FAQ: E35 Excavator, Concrete Pump, Denali Truck, & Engine Hoist – Insights from an Admin Buyer

Searching for a paper crane tutorial? You’re definitely in the wrong place. But if you’re trying to figure out whether the Bobcat E35 excavator is right for your fleet, how a Bobcat concrete pump attachment performs, whether your Denali truck can haul it, or what engine hoist you’ll need for service work—you’ve landed where you need to be.

I’m the office administrator who handles equipment purchasing for our mid-size contracting company. I manage roughly $200k in annual orders across 8 vendors. Over the past 5 years I’ve learned that the “right” answer depends on context, budget, and a few hard lessons. Below are the questions I hear most often from our sales team and sub-contractors. (And yes, I’ve made mistakes so you don’t have to.)

Frequently Asked Questions

1. What are the real-world specs of the Bobcat E35 excavator?

The E35 is a 3.5‑ton mini excavator with an operating weight around 7,700 lbs and a digging depth just shy of 10 feet. Those are the numbers you’ll find on Bobcat’s site (accurate as of January 2025). But the spec I care about more as a buyer is auxiliary flow—11.2 GPM standard, up to 14.5 with high‑flow option. That determines what attachments (like a concrete pump) it can run. After 5 years of managing our fleet, I’ve come to believe that attachment compatibility matters as much as weight and depth. Three things I always verify: hydraulic flow, coupler system, and pin-on pattern. In that order.

2. Can you really run a Bobcat concrete pump on an E35?

Yes – Bobcat offers a hydraulic concrete pump attachment designed for compact excavators. The key is matching the pump’s flow requirement (usually 10–15 GPM) to the machine’s auxiliary flow. We started using one in 2023 for footings and small slabs. I didn’t fully understand the importance of cleanliness until a $3,000 repair after hardened concrete jammed the check valves. Now we flush the system immediately after each pour. The upside was saving two hours per pour versus a separate concrete pump truck. The risk was downtime if we got lazy with cleaning. All worth it if you’re disciplined.

3. Will my Denali truck (GMC Sierra 2500HD) handle towing a Bobcat E35 + trailer?

It depends on the configuration. A properly equipped Denali 2500HD has a max towing capacity around 18,000 lbs. The E35 weighs ~7,700 lbs; a typical trailer adds 2,000–3,000 lbs. So you’re at roughly 10,000 lbs – well within capability. But (and this is critical) your payload capacity gets eaten up fast by passengers, tools, and the hitch weight. In our 2024 vendor consolidation project, we discovered one of our subcontractors was overloaded on the rear axle by 500 lbs using a ¾‑ton Denali. The fix was a weight‑distributing hitch. This worked for us, but if you’re towing across mountains, your mileage may vary. Always check your specific VIN’s payload rating.

4. What size engine hoist do I need for Bobcat engine service?

For the E35’s Kubota D1703 engine, a 2‑ton (4,000 lb) rated engine hoist is plenty. The engine itself weighs about 400 lbs – even the whole power unit with radiator and exhaust is under 700 lbs. The real lesson I learned (after a near‑tip incident in 2022) is to always use a load leveler. An engine hoist’s rated capacity assumes the load is centered. Tilt the engine and the leverage multiplies the load. Three things: capacity, boom length, and tire condition. Check all three before you lift. (Ugh, that near‑miss still makes me cringe.)

5. How has Bobcat equipment changed in the last few years?

The fundamentals – hydraulics, engine, undercarriage – haven’t changed radically. But what’s evolved is precision and telematics. Five years ago, “machine health” meant checking fluids yourself. Now Bobcat’s cloud platform sends me alerts for service intervals and even operator abuse (like high idle time). What was best practice in 2020 – buying a used machine from an auction – may not apply in 2025 because the electronics tie into dealer support networks that only work with a full service history. I learned this when a second‑hand loader we bought in 2021 couldn’t be updated to the latest firmware without a $1,200 dealer unlock fee. Tech changes how we think about asset lifecycle.

6. What’s one thing every administrative buyer should check before ordering attachments?

Beyond specs – lead time availability. In Q3 2024, we ordered a concrete pump attachment that the dealer said was “in stock.” It arrived three weeks late because the hydraulic hoses were on backorder. The delay cost us a job (and made me look bad to my VP). Now I verify not just the part availability but the component availability. Ask your dealer: “Do you have the couplers, hoses, and fittings locally, or do they ship separately?” This simple question would have saved us $2,400 in lost revenue. (Thankfully, we switched to a dealer who maintains a local parts warehouse.)

As of early 2025, these insights reflect my experience. Prices and specs change – always verify current data at Bobcat.com or your local dealer before making a purchase decision.
