77 Wide Front?

Is it possible and practical to convert a 77 row crop to wide front? The tractor is in great shape. I've added a 3 point hitch and bucket loader, but that narrow front end makes it unusable on anything but flat ground. Are there any wide fronts available? If so, how hard it is it to convert. Mine has power steering.

Thanks, Jim Murray - Hartsville, IN

I have a 1951 77 with a wide front. If your going to be using the loader a lot I would keep your narror front. They arn't that bad if your in the feild but if your doing a lot of close turning there useless. The wide fronts off of 770's will also fit them.

Jim,

I converted a narrow front end to a wide one on a Super 77. Its not tough to do as long as you have a way to support the tractor while swapping front ends. I got my wide front end from Maibach Tractor at Creston, Ohio. You mentioned that you have power steering. Is this the Char Lynn type unit that is placed in the steering shaft that has a seperate pump ran by belt off the crankshaft pulley with a resevoir under the hood ? The 2 front ends were self contained with each one having a different type of steering gearbox. I used the cultivator pipes through the frame holes as well as wood blocking to support the tractor. After removing the narrow front bolts and disconnecting the universal joint it comes right off. The wide front used the same mounting holes as the narrow front as well as 3 additional holes further back on the underside of the cast "tub" to fasten the axle support and pivot to. Attach the universal to the steering gearbox shaft on the wide front and you are done. It did not affect the performance of my power steering at all. My power sterring was an add on unit and was not factory original. Email me if you want more information or some pictures.

Hope this helps !

On my 88 I can switch from narrow front to the wide in about an hour or so. I jack the front up by putting a 6X6x24 block just in front of the pan cross ways on the frame. Take the bolts out of the steering retainer at the belling housing, then take the bolt out of the U joint on the front end. Then take the bolts that hold the casting to the frame. The other front goes back on by reversing the above directions. I use floor jacks and an engine lift for the lifting. The wide fronts are out there, I can't help you with that.

Jim yes they are convertable to a wide front end, Oliver made wide front ends. I beleive that if you really just wanted a wide front end that one from a 1600 Oliver will bolt up to it and you can probably find one at a salvage yard. As for the ease of changing one you might want to get a repair manual to help you do this or consult somebody that works in a White Oliver Dealership to show you some easy tips on the change over. It really isn't that hard the first thing you have to do is take the cover off of the powersteering cylinder (the rubber thing in the center with the spring around it) you will see a bolt head, take a breaker bar and break the bolt loose. Back that bolt out until you feel it getting tight(the bolt has a washer welded to the head of the bolt and it is now pushing up against a snapring)keep backing the bolt out until you feel it break loose a second time, this will release the gear and bolt assembly from the steering shaft. Now back the bolt out completely until it no longer raises the cylinder, Jack the tractor up take the bolts out of the narrow front end and carefully remove it and install the wide front end in reverse order. P.S. Make sure that both front ends are facing straight foward as you remove and reinstall so that it will remain in time. I hope this helps Good Luck Shadetree.
