Will a 54" plow off of a 445 fit a 425?

Yes, anything from one will swap to the other.

Same frame on those tractors. Does the 425 have 2 hydraulic circuits and a bypass valve for the rockshaft cylinder? I know that my x475 did not have the bypass valve and it was added by the dealer. It prevents the rockshaft cylinder from moving which prevents a delay when you are angling the blade. You could always make a mechanical stop to keep it from moving but it wouldn't be as easy as turning the valve.

the 425 does have 2 circuits but not sure on the valve but that is an easy fix. 

 

Looking at possibly upgrading my 318 to the 425.

The 425/45/55 tractors are identical, just the motor is the difference.

 

425 = Carb

445 = Fuel injected

455 = diesel

 

All three had the option of all wheel steering. 1993-1997 models had the brake/neutral/seat/pto safeties, the 98-2001 models added the dreaded RIO switch to the mix. (hold switch up to back up when pto is engaged or engine will die)

 

'93-97 gas models used a plastic camshaft gear that had a high % of failures. By now though, they've either failed if they were going to or they have been replaced with the steel upgrade.

So what was the tire sizes used on the two wheels steer models? I have seen them with both sizes but have never been able to put a handle on them as far as if the larger size was optional or standard.

23x10.5x12's the first year on all models, then the aws models the subsequent years. 26x12x12 on all 2ws models, 1994 on up. I've read the 26's were optional the first year on the 2ws models.

I have seen a lot of 400 series with the smaller tires and here an example of a reportedly 1999 low hour 425 with the small tires so it makes me curious if they did use the smaller tires for some reason on some later tractors.

I'm wondering if the 26's were optional through the whole run on the 425. I've seen more with the 23's than not, come to think of it.

I've always been under the impression that all 425's came with 23's on the rear and 16's on the front. The 445's and 455's came with 26's and 18's.
