1450 Loader Questions
3 Attachment(s)
Hi All, New to the forum, I just picked up a new to me 1450 with a homemade loader.
The loader is ran off the rear end and seems to lack power it’ll lift max about 200 lbs very slowly. I am assuming this should be able to lift more and is probably due to the fact it doesn’t have its own hydro pump. Moves snow great as is but come summer I have some gravel I want to move and I don’t think it’ll be up for the task. Upon research on the forum I’ve decided I need a separate pump, hoping to run this pump off the electric pto up front to be able to disengage for winter starting. https://www.northerntool.com/shop/to...1998_200641998. Three questions: 1)Does this pump look right? from the research I have done seems like I need about a 4gpm pump. 2)I couldn’t find much information about reservoir size, are there any recommendations? I know a lot of people use the loader arm. 3)How do I bleed the current system, it seems like my left lifting cylinder has some air in it, seems to lag the right one by about a half inch, making my bucket un even. Hopefully I’ll figure out how to get a couple photos loaded |
I believe one I got 4-8 gpm pump. At 1800 RPM it's 4 gpm and 8 gpm 3600 RPM, but I have to check. at lease gal. I making tanks so I can have a 4-5 gal. capacity. But, I'm building back hoe.

You say "ran off the rear", I assume you mean off the hydrostat??
The internal pump is small, but is large enough to operate a loader. If the system seems weak, check the charge pump output pressure and correct as necessary. It's in the chassis service manual. If you add a pump, you will have to add a reservoir. Plus all that work. I'd just fix the charge pump pressure and see how it works. If you think one cylinder has air in it, all you do to remove it is do a couple complete cycles of the cylinder. Full up to full down. Air can make it "lag" behind, but I doubt that is the issue. A "T" hydraulic system will split the load equally between the two cylinders. If one is behind the other, it's likely that the builder didn't get the frame made the same on both sides. But, if you want to make a mount, and reservoir, do all that plumbing.... be my guest. You may find you have the same issues still.... |
I also have a 1450 with a Johnson loader on it. When I got it, it was also run off the ported pump. I added a separate hydraulic pump, ( and power steering) the ported pump just does not have enough power for the loader for what you want to do. After changing mine to a dedicated pump it made a world of difference. Here is the pump I used https://www.northerntool.com/shop/to...9708_200329708
If you are going to run it off a pulley, make sure the pump is rated for a side load. I ran mine off the front PTO. Hope this helps |
First of all thank you all for the responses and input!

I bought the tractor from a guy who bought it at an auction non-running. He fixed the spark issues and decided he wanted more lift capacity and sold it to me. |

It shouldn't matter but then again I try to plumb the supply into the branch of the tee with the load out of the run. Then run equal length and diameter hoses to the cylinders.
If a 3pt hitch can lift 1000 lbs off the charge pump, you have something wrong only able to lift 200 lbs. But it might be doing your tractor a favor since THOSE FRONT ENDS ARE NOT BUILT to load the piss out of them. Could be the builder derated the charge pump to protect his tractor. Are cycle times the same when it's loaded and empty? |

When loaded it slows significantly. |

If you don't know the pressure, you are wasting your time with anything else. |
