I'm absolutely blown away! I truly long for an antique D9. The sound, strength, and dimensions of those machines are simply unmatched.
It's amazing to see an old machine being restored and given a new lease on life instead of being discarded. The smile on the owner's face says it all! I wish I had a D9 bulldozer!
I used to own some rugged old machines, such as a 19A with a cable blade and a twin disc torque converter that ran on diesel fuel. After using it for about 10 years, I sold it to a friend who still starts it up occasionally. Another machine I had was an 18A with an oil clutch and 6-speed transmission. When it started giving me trouble, I ended up scrapping most of it, but gave the bottom tracks and planetary gears to a friend. - Don

Looking for information on durable old machines with a cable blade and twin disc torque converter running on diesel fuel? I used to own a 19A model for 10 years before passing it on to a friend who still occasionally moves it around. I also had an 18A machine equipped with an oil clutch and 6-speed transmission. When it started causing issues, I decided to scrap most of it, but gifted some parts to a friend. - Don
It's great to see her up and running! I'm impressed that you were able to get that vintage fuel to ignite.
I was surprised to learn that the TC ran on diesel fuel. Initially, I thought it was a mistake. I was puzzled by the presence of a hand clutch since I wasn't familiar with TCs. It was impressive that it could still run on fuel that was 20 years old. However, it developed a fuel leak near the filter housing attached to the injection pump, possibly due to clogged fuel filters. During the incident, fuel sprayed everywhere, leading to a debate between me and another individual over whether it was diesel or antifreeze. Surprisingly, it had no discernible odor, taste, or color. Despite the leak, the TC continued to operate.
The transmission remains essentially unchanged, operating with mechanical gear mechanisms similar to a direct drive system. To shift gears, it is essential to have a method for disengaging the drive.
The standard transmission in the tractor is located behind the torque converter, which features a 3-stage design. The torque converter smoothly transitions into high range until it encounters a load, such as a full blade or a tractor pan being pulled. The 19A model excelled as a tractor pan machine, while the 18A model was ideal for steep ground and ripping tasks. The 19A tractor was impressively fast until the blade was loaded. During a landfill reclamation project, I found it to be quicker and more agile than the 66A tractor, as well as lighter with superior flotation capabilities. Overall, the 19A proved to be a versatile and efficient machine in various working conditions.
The Cat brand incorporated a similar configuration in the 15A D8, essentially a 14A model with a TC. It seems like this setup wasn't very popular, as production only lasted for a few years. It's worth noting that the early 46A models also featured a fuel charging system.
It's such a shame that the farmer near me decided to scrap his D9G, he's really missing out on the value of such a great machine!
In the early 1960s, Allis-Chalmers also experimented with using a torque converter over a manual transmission on the HD 11 bulldozer. It is unclear whether it utilized diesel or oil as its fuel source.
Are you planning to share additional footage of the vintage car moving around the estate? Discover more videos of the classic vehicle in action on the grounds.
powersmoke18 expressed disappointment in a nearby farmer who scrapped his D9G. Despite this, they wonder if the farmer has any other untouched pieces of machinery.
Could you please provide more video content for me to watch? Thank you.
According to DPete, Cat introduced a configuration in the 15A D8, similar to the 14A with a torque converter (TC). This model may not have been popular as it was only produced for a limited time. It is worth noting that the early 46A also featured a fuel-charged TC. Additionally, the 35a model, known as the 8h, also had a fuel-charged converter. This information was shared via Tapatalk from a DROIDX device.
I believe I spotted the smoke cloud here in New Jersey when you all ignited that!
The Komatsu 150 model explains that its transmission is a traditional mechanical gear transmission, like a direct drive machine. To shift gears, a dry clutch between the flywheel and torque is used to decouple the drive. This enables smooth gear and direction changes for optimal performance.
It is truly amazing to witness the revival of items like this.
Roadswitcher mentioned that Allis-Chalmers also experimented with the concept in the early 1960s with the HD 11 model, although it is unclear whether it utilized diesel or oil. Additionally, our vintage HD16 cable blade from the late 1950s operated on diesel for the torque converter.
