Wade, your machine is a good machine dont get me wrong Im sure it will do everything you ask of it. Bobcats are the only skid I own. Its just that we work the hydraulics very hard and was hoping that the new one would be better.
WI yes the 300's will shutdown as well, they just dont have as much back pressure on the return side so in turn generate less heat. Its funny the first time we hooked our processor up to the new Mseries and ran it I told my bobcat salesman that it was working harder than the 300's, he said oh no you just have to get used to it. When the bobcat rep came out to my shop and plugged in his computer to the Mseries he says holy cow you shutdown every 5 hours on high Hydraulic oil temp, I said yes that is what I told you on the phone.
Gotta love engineers that are never out in the real world.
It all worked just dandy on their computer screens, you can't be having this problem.
Mine had that issue thankfully when it was still under warranty. We were driving up and down a very steep hill nonstop with the tracks sinking quite a bit. The temp would get very hot. I kept telling the dealer that it was getting hot and I would take it in to them. They would put the auxilary to work and load it heavily with a meter. Then insist that it does not get hot under load! lol. I take it back to site it gets hot. Back to dealer, "We loaded it so hard it would be impossible to replicate that level of stress on a jobsite. Ran it for a long time and no temp change". It turned out the fan was only running on low speed. Supposed to kick into a higher one as req'd.
