Loaders using rear remotes

[mo1]

That is true for some Deeres, certainly not all, and certainly not on anything built after the early 1990's.

If I remember correctly, Deere initially used open center hydraulics, introduced some closed center models in 1960 with the 3010/4010/5010, added more closed center models with the 20, 30 and 40 series, and then by 1980, essentially everything Deere themselves made was closed center. A 2030 is closed center. However, the Yanmar-made compacts were open center. Deere went back to open center in the 5000 utility tractors in 1993 and all 5 series units are open center. The 6000 series has a mix but the 6D and 6E are open center, 4 cylinder 6x30s and 6Ms can be had either way, and pretty much anything 6 cylinder was and is closed center.

Putting a power beyond on an open center Deere involves removing three pipe plugs and plumbing in 3 lines. This is how Deere uses a mid-mount loader valve, it's run off of the power beyond.

Running a loader off of rear remotes was commonly done in the pre-loader-joystick days if the tractor had two rear remotes. You would use the tractor's spool valves to control the loader. If it did not have two remotes, the power beyond was used to feed a set of spool valves mounted to the loader, which was not generally considered removable. Later on the two spool valves became a joystick, and then after that the tractor manufacturers started to use their own tractor-mounted joysticks to control remotes. In the 1990s when tractor mounted joysticks were new, some tractors used the joystick to control the rear remotes which were then connected to the loader, and some used the then-brand-new separate mid-mounted remotes as we would use today.

The concept of a return in the filter cover was limited to pure high pressure closed center systems used from 1960 till about 1990. That style return was not used on any open center or CCLS/PFC systems during that period or after.

Loaders that run off the rear remotes were a cheaper way to connect the loader and use existing controls, prior to the joystick era it made for a much cleaner installation especially on a cab tractor. If the remote levers are comfortable to use then no worries, biggest drawback is it ties up your valves if you want to use the remotes for something else with the loader mounted.
