![]() Not something that I ever want to do again, but for a $22,000 savings in buying a replacement unit to having it rebuilt, I guess it's kind of a no brainer. Installing it again was ALLOT harder then taking it out. They said they would not warrantee the pump unless they went through the drive motor to make sure it was clean of debris. Cost to rebuild the pump was $2K and the drive motor was another grand. I pulled the pump and drive motor out myself and brought them to the shop to have them rebuilt. I had to back it up from the area I was clearing, to my work shop. That quickly went from very annoying, to totally losing all forward control. I would push forward, then try to go backwards, only to have it sort of turn on my first and do it's own thing. When the pump started to fail, the first thing that I noticed was that it stopped responding to what direction I wanted to go. Hopefully your local Deere dealer will be more helpful then what I experienced. They have allot of power and I'm pleased with it overall, just not excited about Case and their lack of support for this dozer. ![]() I use my dozer on my land, so it's not that big a deal. ![]() On my Case, it either does fine, or you have to give it a little more pressure on one side or the other to keep it going straight. Like already mentioned, one of the biggest complaints about the drive of the pumps is keeping them adjusted so they track evenly. They machined those parts themselves after failing to find them for sale anywhere. Same story, Deere no longer carried those parts and you had to buy an upgrade, replacement pump. Later, when I had it in the shop for a rebuild, the guys at the shop called Deere to see if they had a few parts that they couldn't find. I might be that I have a Case dozer, but they would never confirm that it's the same pump, but never got back to me on the price of a replacement pump. I called Deere and they pretty much said the same thing, but were not as helpful about it. When I lost control of one of my pumps, I was told by Case that they no longer support those pumps and that a retrofit, new, replacement pump would cost $25,000. I don't know what model 850 they were used in, but it is hydrostatic drive. We are excited to launch the 850 X into the market soon after all testing is completed.I have a Case 1550 dozer and it has the same Sundstrand hydraulic pumps in it as the 850 Deere. We've brought many customers into our factory to gather feedback and ideas, tune the performance, and ensure we hit the mark in all areas. Throughout the development process we have held multiple customer advocacy groups. John Deere 750C,850C Crawler Dozer Repair Manual TM1589 Category: John Deere. These preliminary specs may change when the dozer goes to market.Īccording to Goedert, "We are currently accumulating hours and undergoing extensive testing to ensure the machine performs and exceeds customer expectations to provide the most value possible. The 850 X delivers 225 hp (168 kW) has an operating weight of 47,578–51,365 pounds (21,581–23,299 kg) undercarriage configurations include XLT, WLT, and LGP and blade configurations include Power, Angle, Tilt (PAT) and Outside Dozer (OSD). The electric drive puts less parasitic load on the engine and enables the engine to run at a lower rpm, improving fuel economy and reducing noise levels. When operating in applications with light to moderate loads, such as during fine grading or spreading, customers will experience fuel savings compared to a traditional dozer. The machine will keep pushing and will carry material quicker. Goedert adds that customers will feel a significant difference in cut and carry applications where the machine is put under high load. When operators need to move material from point A to point B, they need to do it as efficiently as possible, and the high-torque of John Deere's E-Drive delivers more pushing power to the ground. The two big benefits of hybrid technology are fuel savings and a boost in productivity. ![]() According to Matt Goedert, solutions marketing manager, John Deere has been working with this technology for over a decade since introducing the 644 X wheel loader in 2013 and the 944 X wheel loader in 2015.
