Comparing Four Dozers: Case, Komatsu, and Two Cats

Overview of the Dozers

• 🚜 The video showcases four dozers currently on the farm: a Case 850M, a Komatsu D39, a Cat D6D, and a Cat D7F, representing a range of sizes and ages.
• ⚖️ The dozers are categorized by weight: the Case and Komatsu are around 25,000 lbs, the D6D is approximately 34,000 lbs, and the D7F is about 50,000-52,000 lbs.

Case 850M LGP

• 💡 This 2025 model is an LGP (Low Ground Pressure) dozer with wider tracks, ideal for floating over mud and wet conditions.
• ⚙️ It features a six-way blade for versatile shaping and comes standard with universal mounts for GPS control systems.
• 🔊 A minor con is that the cab can be a bit loud, with controls being electric over hydraulic, making them more sensitive than pilot controls.
• 💪 The dozer has around 110-120 horsepower, more than the Komatsu.

Komatsu D39

• 🏆 This 2016 model is praised for its exceptional grading capabilities and excellent visibility, with a smaller hood and the radiator located at the rear.
• ⚠️ The primary drawback is significant emissions problems and downtime, leading to a love-hate relationship with the machine.
• 💨 The engine is noted as being quieter than the Case, though it has a distinct rattly sound.
• 🛡️ It is equipped with sweeps and cages for protection, and a root rake mount is available.

1984 Cat D6D

• 🛠️ This older, open-cab dozer is described as a good old raw power machine with no electronic bells and whistles, perfect for clearing and pushing large piles of brush with a rake.
• 💨 The main downside of the open cab is exposure to the elements and dust, which can be significant in dry conditions.
• 🚧 It's not ideal for fine grading due to a worn blade but is robust for rough work like root raking and pushing brush.
• 🌲 The lack of glass makes it less susceptible to damage when working in wooded areas.

1972 Cat D7F

• 🚀 This restored military surplus dozer, despite its age, has very low hours and underwent a major overhaul, including a new engine and transmission.
• 🎯 It excels as a heavy-duty pusher, ideal for hogging dirt, but is not suited for fine grading, requiring smaller dozers for that task.
• 🕹️ Controls are power shift, and steering is managed via handles, not pedals, which can be less comfortable over long periods.
• 🧐 Visibility is limited due to the large hood, requiring operators to work largely by feel, especially when trying to see blade corners.

Dozer Size and Transport Considerations

• 🚚 Transporting larger dozers, like a D8 size, becomes challenging when the blade exceeds 12 ft in width, often requiring a pilot car and incurring significant extra costs.
• ⚙️ The older machines, like the Cats, are praised for their dependability as long as they have batteries and fuel, though they require more skill to operate compared to modern dozers.
