### **Pros and Cons of Buying a 2021 Doosan DX35Z-7 Mini Excavator with Hydraulic Thumb and Bobcat E35 144**
#### **Overview of the Machines**
The **Doosan DX35Z-7** is a compact, track-equipped mini excavator designed for versatility in tight spaces, while the **Bobcat E35 144** is a skid-steer loader with a hydraulic thumb attachment. Both are powerful, efficient machines, but they serve different primary roles. Below is a detailed comparison of their strengths and weaknesses.
---
### **Doosan DX35Z-7 (2021) Pros and Cons**
#### **Pros:**1. **Excavation Capabilities** The DX35Z-7 is optimized for digging, trenching, and heavy earthmoving tasks. Its **35-ton breakout force** and **2,100-lb bucket capacity** make it suitable for foundation work, landscaping, and utility digging.
2. **Track-Based Stability** Tracks provide superior traction and stability on uneven or soft terrain compared to skid-steer loaders, reducing slippage and improving control.
3. **Hydraulic Thumb Compatibility** The hydraulic thumb attachment enhances versatility, allowing the excavator to handle materials like wood, debris, or small concrete blocks without additional tools.
4. **Compact Size (7.5 ft width)** Ideal for working in confined spaces such as residential lots, urban construction sites, or tight job sites where maneuverability is critical.
5. **Fuel Efficiency** The **3.3L diesel engine** (with **Doosan s fuel-saving technologies**) offers better fuel economy than many skid-steer loaders, reducing operational costs over time.
6. **Durability and Build Quality** Doosan is known for robust, long-lasting machinery with strong aftermarket support, reducing downtime.
7. **Versatile Attachments** Beyond the thumb, it can accommodate breakers, grapples, and augers, expanding its utility for different tasks.
8. **Lower Ground Pressure** Tracks distribute weight more evenly, minimizing soil compaction compared to wheels or skid-steer tracks.
9. **Ease of Maintenance** Doosan s design simplifies servicing, with accessible components and a reputation for reliability.
10. **Resale Value** Well-maintained Doosan excavators hold value better than some competitors due to brand reputation.
#### **Cons:**1. **Limited Lifting Capacity** Unlike skid-steers, the DX35Z-7 is not designed for heavy lifting (e.g., moving large pallets or heavy materials). Its **max lift capacity is around 2,100 lbs**, which may be insufficient for certain material-handling tasks.
2. **Slower Speed** Tracks are slower than skid-steer wheels, making it less efficient for transporting materials over long distances.
3. **Higher Initial Cost** A new or well-maintained used DX35Z-7 will typically cost more upfront than a comparable skid-steer loader.
4. **Operator Skill Dependency** Excavators require more training to operate efficiently, especially in tight spaces, increasing labor costs if operators are inexperienced.
5. **Attachment Limitations** While versatile, not all attachments are as easily interchangeable as on skid-steers, which often have quick-attach systems.
6. **Less Versatile for Material Handling** If your primary need is moving loose materials (e.g., dirt, gravel, mulch), a skid-steer may be more efficient due to its bucket capacity and speed.

### **Bobcat E35 144 (Skid-Steer Loader with Hydraulic Thumb) Pros and Cons**
#### **Pros:**1. **Material Handling Efficiency** The **E35 144** is built for **fast, efficient material movement**, with a **1,440-lb bucket capacity** and **high lift heights (up to 10 ft)**, making it ideal for loading trucks, moving dirt, or handling mulch/sand.
2. **Speed and Mobility** Wheels allow for **faster travel speeds** (up to 15 mph) compared to tracked excavators, making it more efficient for transporting materials over short to medium distances.
3. **Quick-Attach System** Bobcat s **QuickAttach** allows for **fast, easy attachment changes**, including the hydraulic thumb, which enhances versatility for tasks like moving logs, pallets, or debris.
4. **Lower Operating Costs** Skid-steers generally have **lower fuel consumption** than excavators of similar size, and their wheels reduce wear on soft ground.
5. **Compact Yet Powerful** At **5.5 ft wide**, it fits in tight spaces but still delivers **35 hp** of power, making it suitable for both light and moderate tasks.
6. **Ease of Operation** Skid-steers are **easier to maneuver** in confined areas and require less training than excavators for basic tasks.
7. **Versatility with Attachments** Beyond the thumb, it can use **hydraulic breakers, pallet forks, brush cutters, and more**, making it a multi-tool machine.
8. **Lower Purchase Price** Generally **cheaper upfront** than a comparable excavator, especially in the used market.
9. **Better for Finishing Work** Ideal for **landscaping, snow removal, and utility tasks** where speed and material handling are prioritized over deep digging.
#### **Cons:**1. **Limited Digging Depth** While it can dig, its **bucket depth is shallower** ( 6 ft) compared to the DX35Z-7, making it less suitable for deep trenching or foundation work.
2. **Ground Pressure Issues** Wheels can **compact soft soil**, making them less ideal for delicate ground conditions (e.g., turf, sensitive landscapes).
3. **Less Stability on Slopes** Skid-steers are **prone to tipping** on steep or uneven terrain, whereas tracked excavators are more stable.
4. **Attachment Wear** Frequent attachment changes can lead to **wear on the QuickAttach system** over time.
5. **Higher Fuel Consumption in Idle** Skid-steers often idle while waiting for tasks, increasing fuel costs in some applications.
6. **Less Precision for Fine Work** Excavators offer **better control for delicate tasks** (e.g., utility cuts, precise grading), while skid-steers are more suited for bulk work.
7. **Resale Value** While still strong, Bobcat skid-steers may depreciate slightly faster than Doosan excavators in some markets.
