New Holland 404 Crusher

Stem crushing implement, drag type, steel drum on top, rubber covered like swathers-haybines on the bottom. Sickle cut thick stemmed crop then come back with this to crush the stems....integrated into swathers-haybines of later years.

Question is, for road transport, I can't find any way to raise the rollers. 3 adjustments: Side 2 adjust tension between rollers and small one at front changes the drawbar angle for larger or smaller WWs. It does nothing to raise implement.

Thanks for your time,
Mark
 
I own one and there is a height adjustment. Cant say how high it will go as I'm not in a position to take a look at it. There are only 2 adjustments - tightness of the rollers and height from the ground.
 
I agree with Charlie. We have three 404 crushers. Moving the middle crank raises the roller assembly somewhat. You can get the bottom roller at least 3 inches from the ground, maybe a little more. Have never had any problem with road transport this way.

They are old, but good machines. Save at least a day of drying around here.

Mine has a lever with a rope to lift the pickup from the seat. No height adjustment for the rolls.

Thanks guys for the quick responses as I need to go to the field today. I am going to assume that the bottom roller is tough enough that when road transporting, if the curvature of the surface should be such that it contacts the bottom roller, it's tough enough to roll over the road and if necessary, support the weight of the entire machine. With the Ford 3000 the PTO has no lock and the roller is free to roll over the road just as the tires do.

Next question:

How hard is it to change out the bearings on the end of the top roller? The "curb" side seems to be pretty easy. How about the gear side? Any suggestions?

Thanks,
Mark
 
The one in the middle? I ran that lock to lock and it does little for road clearance. Seems to be for minor field variations/crop type/volume.
 
Per your comment I drug it over to a hard surface and tried the 3rd adjustment handle again. This time I could see that it did indeed
provide road clearance in addition to ground level adjustments.

Thanks for that tidbit sir.
 
We have changed a few of those bearings. They have to be cut apart with a oxy/acetylene torch. Cut into the outer race enough to get all of the balls out. Then the outer race will fall off. Cutting the inner race takes some finesse with the cutting head. You have to cut at a tangent to the shaft. Just gently shave it off. If you try to cut parallel to the shaft, it will blow back at you. Pulling the gears/clutch etc on the drive side may take more time than bearing replacement.

Order your bearings from Joe's Machinery in Pennsylvania(717-464-1043). They are odd size self-aligning bearing and I have not been able to find them aftermarket except from Joe. About $60 each. P/N JM86575514.
 
Those bearings are $90-$100 from New Holland.
Cannot find them aftermarket with a big enough outer race for the proper bore size.

Thank you so much sir for taking the time to walk me through that and give me a reasonably priced source.

I don't know if they are what's making the noise but I suspect such on the curb side of the implement. No clunking yet, just rumbling.
Thought about drilling a small hole in the seal and using a pointed grease tip, injecting some grease in it to see if that is making the noise
and shut it up. For what you just told me that just may be my first option.
