Cub Cadet Model 1450

istechjr · Jan 11, 2018

I have a Cub Cadet model 1450 that all of a sudden it will not lift the Snow Thower. If I disconnect the linkage it will move but not very well. Can anyone help me try to fix this?

Two things to check first.

(A) Is the Hydro Fluid to the proper level? Remove the Rear End Cover...Plug. If properly filled, it should just start to run out. If not, add HyTran Hydro Fluid.

(B) The Hydro Filter may be partially restricted. IF......that is the case, then it is time not only to change the Filter, but the Hydro Fluid as well.

I just replaced all the fluid as well as the filter.

I worked the valve for about 1/2 hour thinking that there was air in the lines.

thanks for the thought however.

Since you have to remove the Rear Cover Plate to change the Hydro Fluid, did you clean up any residual "gunk" that usually is in there, making the rear end really clean...???

istechjr · Jan 13, 2018

Yes I did and everything looked really clean.

The "implement relief valve" in the hydro transmission could have debris in it, or it's spring could have broken.

If you can "T" into the line from the pump to the valve, pressure there should read around 800 PSI with the cylinder full extended or fully retracted and the control lever held in the "lift" or "lower" position.

Other possibilities...I suppose something could have happened inside the control valve, or possibly the piston seal inside the hydraulic cylinder could have failed.

I've attached a link to the factory service manual for the hydro below.

Does the tractor move forward and reverse "normally"......????

istechjr · Jan 14, 2018

Yes the tractor seems to move forward and reverse like it should.

Then there is some restriction in the "lift circuit", to include piping, control valve, and/or hydraulic cylinder.

I had a more basic problem with my 1450 when it wouldn't life. The roll pin in the rock shaft broke. It was a pain to line everything up and drive the broken pin out.

I have had that happen too. BUT...if that happens, then the tractor won't move forward/reverse normally, and HE said it did.

Check your hydraulic piston mounting to frame, it may have worked itself loose.
