1450 Loader Hydraulics Plan

[swensond]

Hello all,

I'm in the planning stages for adding a light loader to my 1450. The plans I want to use are for the single-arm CadLoader model 507 (photo attached).

I have my reasons for going with this model over the traditional double-arm design:

• I want the loader to be easily removable so I can still use the OEM snowplow with power-angle
• I'm comfortable with the 400lb capacity of this design
• I think it looks cool
• Finally and most importantly, I THINK it will allow me to avoid having to add an auxiliary hydraulic system (PTO-driven pump, tank, filter, etc.)

That last item is really why I want feedback from this crowd. I've seen in other threads that there is no way to do a loader with the OEM ported pump, but hear me out! This design only has two cylinders. According to the designer, it requires a flow of "0.8-2.0 gal/min" and is designed to operate at a max pressure of 700PSI. My research shows that this should be well within the capabilities of the implement side of the OEM hydro on my 1450. If I'm missing something, please let me know!

Right now I have the OEM dual-spool valve on my 1450 that I use for the snow plow lift and power angle. As I mentioned, I would very much like to preserve that functionality. My plan is to install a 3-way valve on the pressure supply line coming from the pump so that I can select a secondary circuit with a second dual-spool valve to control the loader cylinders. I would run the low-pressure/return lines from both control valves into a "T" fitting and then back to the return on the pump.

I made the attached drawing of my plan and I was hoping some of you could take a look and offer any criticism or suggestions before I start buying parts and tearing things apart.

Many thanks in advance!
