I'm willing to bet that your tractor is filled with the wrong hydraulic fluid. I have the exact problem you are referring to, however, mine only begins to have power issues when it gets fully warme. Latter in the day I need to rev it up to 1500 rpm or more to raise the tiller.Ĭan you advise how or what the problem is?. When first started it will raise the 3ph no problem at a very low idle. I have the exact problem you are referring to, however, mine only begins to have power issues when it gets fully warmed up or otherwise begins to get hot, I think. Guess where it ended up.in and stuck on the 3pt proportioning valve poppets! The first time I decided NOT to, I ended up with a boatload of small white plastic fragments from the five gallon pail in the system. As we change our fluids, use a paint strainer or the like as we pour into the tractor's reservoir for refill. This should be a 'Be mindful' type warning to many.

I'll look into them all and (next time i get to visit my tractor) will run through all the great tips.ĭoes your 3pt lift function at all? Many times if some contamination has passed the filter screen, it will land itself on the proportioning valve poppet and basically reduce the ability to close off when directed to.

If the tractor system relief valve is not functioning properly, you would notice problems with both systems. A lot of set ups have the loader tapped at a front hydraulic block, which means the 3-point is working off the loader valve power beyond port. However, if the loader valve is a single return type the loader exhaust oil will move the 3ph, but the system carries the combined weight.Ĭertainly start with the fluids and filters, but from there you may want to check the tractor's hydraulic pressure relief. I've heard of some pumps with built-in proportioning valves but the 3ph and loader won't operate simultaneously in a typical open centered system. If you aren't sure of the condition of oil, filter and any screens I'd change them. Do you have enough hydro fluid in the resevoir?.
