    XR4155 Won't Stay Running

    The little blueberry lives! Tech came out again last Friday and was able to get things up and running again. Notes: Tech input information into his software and had to wait for a one time use code from an LS corporate rep. Had to wait about 30 minutes. Tractor did smoke a some and didn't run...

    XR4155 Won't Stay Running

    Well, I was able to pick up the update kit from the dealer and get some time in the shop last night. Overall it was a really easy install with the directions, though the pictures weren't always the best. Attached are pictures of some part numbers (kit and EGR valve) as well as some component...

    XR4155 Won't Stay Running

    Weekend update: Got the EGR cooler re-installed Waiting to re-install the turbo until I get the new crossover pipe so I have the most working room Pulled the intake off, it was pretty slimy... Thinking more and more this was all due to a faulty EGR valve like CloverKnollFarms thought Got...

    XR4155 Won't Stay Running

    I agree. I really thought we were going to find a simpler issue like the metering valve, either in the actuator itself or that the fine screen around it was clogged. Couple other thoughts: I'm still surprised the tractor wasn't smoking, I didn't notice a significant loss of power, and that...

    XR4155 Won't Stay Running

    Well, good news and bad news today... Good news is it was the first time I've heard my tractor run in a while, bad news is there's still more work to do and parts to install. I got everything put back together and ready for the dealer tech to come by today. New turbo is a Borg Warner brand...

    XR4155 Won't Stay Running

    I took some time Friday evening to clean up the DPF and pipe that mates it to the turbo. I watched several YouTube videos and decided I was going to take a 2-step cleaning approach - degrease then acid wash. I decided against using my pressure washer, lots of people doing it but I didn't want to...

    XR4155 Won't Stay Running

    No noticeable smoke or perceived loss of power, crazy I know... Should feel like a completely new tractor when it's all done. I pulled my dipstick just for fun. Oil level looks great, but my records show I changed it in November so not many hours. I change the fuel filter and oil every fall...

    XR4155 Won't Stay Running

    I usually ran a minimum of 2,000 rpm regardless of what I was doing (after letting it warm up) and never let it sit idling for extended periods of time. I got that advice when I bought it due to emissions. I've logged many hours at ~2,500 rpm running a finish mower to hit PTO speed and moving...

    XR4155 Won't Stay Running

    I didn't even ask what a new turbo assembly cost... My guess is ~$1,300-1,700 for the turbo assembly based on my online searching. I didn't find the exact one for my tractor but did find one for the XU/MT series. I pulled the turbo off myself to prep things, only a handful of bolts. I took my...

    XR4155 Won't Stay Running

    Took a while to find the problem but I think we did.🤞 Walked the dealer tech through all my troubleshooting notes and continued to go down the fuel route: - Verified all injectors pulsed with dealer software - Verified inlet metering valve functioned - pulled to cycle and I was happy to see...

    XR4155 Won't Stay Running

    Update: - Voltage at the fuse panel matches voltage directly off the battery so it seems like I'm good there - I haven't drained the tank but fuel looked good - When I blew out the main line I blew it from the filter back to the tank - I tried adding a low pressure fuel pump in with no...

    XR4155 Won't Stay Running

    Update: I had a limited amount of free time this past weekend so I started simple. Cleaned up all the battery connections and the battery-to-frame ground. I found that the connection point to the frame was painted over so I broke out the wire wheel to get some good clean metal. That didn't...

    XR4155 Won't Stay Running

    I have a 2017 XR4155 hydro trans with cab and 517 hours, located in Wisconsin. My Scenario: Tractor ran fine when parked but when I tried to start it up back in early February it would only idle at low rpm for ~30 seconds and eventually died, like it was starving for fuel. No codes or warning...

    Buying Advice LS XR 4100 Series Options

    Well, just rolled over 192 hours and figured I’d type up a little update: - My dealer/salesman came through on his word that he would install the remote 3 pt. raise/lower linkage at no cost. I worked with his schedule, but he picked up the tractor late on a Thursday morning and had it back by...

    Service Manuals?

    So my recent XR4155HC purchase came with the standard loader and tractor operating manuals but I found there isn't much related to service. After looking it up online I see places like RCO want $299 for a physical copy of the service manual. After a little more research trying to find a free...

    Buying Advice  LS XR 4100 Series Options

    So long story short I'm looking at a few different LS XR4100 series tractors and would like some input from the forum members. I started off with a variety of brands and models, and it seems like the LS XR series has a great inclusive offering (rear remotes, cruise, etc.) and I like the dealer...

    Hello from WI

    Hello, New member from Western WI. I started my search a couple months ago for a compact/utility tractor and have been spending a bunch of time reading through the various forums. I've had a great experience with a local LS dealer so far and am getting close to pulling the trigger. I'll be...
