I noticed that my stump grinder loses a fair amount of power as the oil gets hotter. I'm seeing oil temperatures between 130-140 degrees F. I'm using AW 46 and was wondering if went to 68 (or higher?) if that would help. When the oil is cold, say sixty degrees, the pressure gauge will show 50...

The pictures show what I'm try to cut. I was looking at a flail ditch mower but I'm not sure my tractor has the HP at the PTO (23) to power a 48" one. Looked at some brush hogs, but I'm not confident that will do a good enough job on the small trees. Opinions? The biggest diameter brush would...

I thought I'd start a separate thread for modifying the hydraulic cylinder for my wood grapple build. I hope it will help somebody in the future who may want to take on such a thing. Also, this is one of those cylinders where the end cap is held in place by one of those rings that you have to...

Time to get going on some winter projects. One thing that I can use is a small wood grapple to pick up the larger logs. I have been using my brush grapple, but that still requires rolling or lifting the the pieces and placing them in piles so I can access them. What I am going to build is a...

I just don't like storing anything with hydraulic cylinders/moving parts outside in the weather. So I built a rack to hold my grapple and forks. Used the empty space above where I park the snow plow for my truck. The bucket is on there now because I have the forks on the tractor. I took a...

I thought I'd start a new thread because I'm probably boring half of you to death with my stump grinder build. I'm at the point in the build where I have to figure out the hydraulic valves. For the up and down and sideways, I purchased a joystick valve which will take care of the bulk of the...

In the process of building a stump grinder for my L3901. Using this first post as a test for uploading images. If I have it figured out and it works, you will see the drawing for the concept I have come up with. It will have an extending boom with hydraulic cylinders to lock it in place...

With the new fuel injection systems, I'm thinking that keeping water out of the common rail (is this what Kubota uses?) would only help prolong pump and injector life. What aftermarket separators are you using and what is your opinion of them?

Does anybody know what the pilot hole size is on the rear wheel of an L3901? Making some wheel weights for mine and I would prefer not removing the wheel to measure it.
