Hi. I have a SVL 95-2s. 2018. Has 400 hours.
I run a disc mulcher on it.
The disc mulcher demands high flow and runs well on this machine.
The combination is experiencing fluctuations in hydraulic power.
Most of the time I can apply flow to the disc and move around the job without much problem.
Sometimes when applying flow to the disc I experience reduced power to the tracks to the point where it hardly moves. I have to shut off flow to the disc then move into position then turn flow back on to the disc and creep ahead.
In typical operation, I can often continuously cut with little to no stopping for disc speed recovery. If I place a large demand on the disc with heavy vegetation or lots of ground engagement sometimes I have to give it a moment to recover some speed. Overall it is a very effective mulching system.
Sometimes I experience lower power to the disc.
For example, I mulched a project where the first couple hours of the day I had regular power almost cutting continuously. Then at noon, the disc was slow to recover speed and I spent half of my time over the next two hours sitting waiting for it to recover disc speed. It was weak.
Another project had a long gradual slope. I couldn’t cut going uphill it would not climb and spin the disc at the same time. I had to drive up the slope then cut on the way down. Then all of a sudden I had tons of power it was unstoppable. I was able to cut a steep slope going up and spinning the disc with demand on it the whole time. That’s the power I would like to have all the time.
My dealer is good. There are no codes no apparent issues. They have tested the hydraulics and valves etc and changed one valve that was showing a couple hundred psi below factory, it didn’t change anything.
The hardest part concerning diagnoses is the intermittent nature of the problem. I would like to try another machine to compare to but don’t have access to one at the moment. When running the machine without the disc there is not enough demand on the system to notice any reduction in power. And it’s not a full in limp mode, it’s more like I’m only at about 70% sometimes.
It has been doing this since I got set up this spring, I have mentioned it to the shop foreman a couple times and the service manager before I officially brought it in for diagnosis. I said it was temperamental or like a moody teenager that sometimes would work hard and sometimes be a slacker. I do understand that there is shared flow between the tracks and auxiliary system and each will affect the other.
Overall I love the machine and would buy another but I could use some help with this issue. If it helps, I am up on my service on all items, I am extremely fussy when It comes to maintenance and upkeep.
Thanks for reading and for any suggestions.
