So I have a X585 that is going to be dedicated FEL machine for me. As mentioned in my sig a few years back we added a CTC FEL to the machine. For the most part this is used around the yard doing various tasks from turning the compost pile (mainly leaves and grass from fall/spring cleanup), spreading dirt and other things. Initially we were disappointed in it. If I had a full bucket of dirt it wouldn't lift it.
After doing some research on other forums we discovered the process of re-shimming the Implement Pressure Relief Valve. Long story short the same K92 Tuff Torq transaxle that is used on the X585 and other JD machines is also used by other tractor manufacturers. Each company sets them up as they choose. JD is on the lower end of the PSI rating for the relief where others are fine with running higher values. From information posted from an engineer at the company they felt setting could be pushed to 1500psi without issue. I re-shimmed the valve and went from an initial reading of about 900PSI to 1175PSI. Now the machine will lift a bucket of dirt. I also found it getting really light on the rear wheels. Needed more weight in the back to run this safely now.
I have a 3pt Hitch, the Harbor Freight Quick Hitch and Heavy Hitch. I normally would take off the 3pt hitch when mowing as it is in the way and I can't have it on when collecting leaves. So this meant I wanted to focus on weight on the rear axle. I looked at wheel weights and fluid. Went the washer fluid route and did about 12 gallons in each rear wheel. I figure that is about 200# total. This has worked pretty well. It is pretty rare that I notice the rear getting light. Doesn't mean it isn't if I am pushing the loader. Now that I am getting a Z950R for a mower and will keep this as a FEL machine for spring/summer/fall, and snow clearing for winter. I will most likely leave the Quick Hitch and Heavy Hitch on all the time unless running the box grader and that will be there in place of the HH. Because of this suitcase weights are a better option for me now. My Z950R will come with 6 of the weights which I only need when the collection system is in use in the fall. I want to make a bracket for the back of the Z950R to mount 2 of the weights to the back when the collection system is off. So I will have 4 weights for most of the year that I might as well just store on the HH on the X585. That is another 168# behind the axle so there is a multiplier there plus the weight of all the 3pt hitch stuff. Would there be any benefit to add an additional weights. I could get another 4 (total of 10) so that at all times I have 4 weights on the X585 and most of the times an additional 4 from the Z950R when not needed on that machine. I don't plan on removing the fluid from the wheels so is this just overkill? 8 of them would be another 336# + the other stuff + the multiplier of being behind the axle. So would it be worth it to spend another $260 for the additional 4 weights or is it overkill on a machine as small as the X585?
