I got to play a little outside yesterday. First of all was weighing the blade and mounting bracket. The blade weighs in at 115 +/- lbs. Bracket is just over 55 Lbs. 160 lbs hanging from those little 3/8" mower lift rods. Not good. I did get better measurements on the mower lift amount, using the frame as the base point. All the way up, the rods are 3-5/8" down. when I lower the lift, the rods are 7-3/8" down. That's around 3-3/4" lift. But, if I change the pivot point for the blade to the front, the blade will be down when the sleeve hitch is up. Not really what I want.

After some time pondering that, I tackled the issue of getting the front lift working. Part 46 in the following pic is the issue. It is a 1/2" rod that has a tendency to bend/ break. It is a PITA to get out of it's home on the tractor.

Here is the rod after I straightened it. The red mark is where stress cracks formed from it bending.

My fix was to take a length of 1/4" X 1" bar stock just a bit longer than the rod. I drilled 2 1/2" holes in 9/16" from the ends (matching the rod length). 2 pieces of rod were inserted into the holes, but not all the way in. Then I welded the holes shut, capturing the rods/studs. The other ends were cross drilled for cotter pins. this was then reinstalled. Doing all this took about 3 hours to accomplish due to the location it resides in. The only way in to it is from under the tractor and the upper cotter pin could only be gotten to with needle nose pliers.

Now I need to build a lift rod from the pivot the end of this hooks to out to the front of the tractor. This will tell me how much movement/lift action I will have there.I am thinking now of how/what I want to make this rod out of due to the weight it will be lifting. The hole dia. it attaches into is 1/2" and it will be in the neighborhood of 16"-18" long. It rides just above the motor mount attachment bolts at the bottom of the frame.

After looking this over more, I see 3 options. #1 is to leave it set up as it is, but add something at the front to keep it from pushing back and breaking the lugs.

#2 is to move the rear mount forward to the rear mower deck mount.

Both these will involve making a more substantial lift rod (instead of the 3/8").

#3 is to wait until I have the other blade and lift mechanism and see if I can clone something to lift from the front.

Since there are no trip springs and the blade is heavy, I will have to be very careful using it. Something will give somewhere and I would rather it be an easy fix when it does.

Sounds like a good, solid fix for that piece. Thanks for the update Kenny.

Thanks, Alan! I am also contemplating using a pair of these at the bottom of the spindle/axle point to ease the steering issue with that blade on there.

But, to do that I will have to shave the bottom of the axle at least .150"-.240" to have room for them.

I got to play some more today. I went to Lowes and bought a 3' length of 1/2" rod. Made up a front lift rod, just not cut to length as yet. So, now I will have front, mid, and rear lift on this tractor. Here's a couple pics:

Rod sticking out the front:

Rod attachment point to lift mechanism:

Image038.jpg

 

The PO had this apart at some time and changed some of the hood mounting bolts to 5/16". They should be 3/8" Also, the RH hood support was a piece of 1/2" conduit bent sorta like it should have been. I acquired a 'NTM' support when I got the wheels and put that in today.

Conduit verses correct piece:

Image041.jpg

He had left out some shims between the hood and grille, causing the headlights to rub on the grille. I made up some out of 1/8" material, needed 3/16. But it's better than it was.

Image039.jpg

Image040.jpg

The hood used to go back past the dash about a 1/2", now it is adjusted much closer:

Image042.jpg

And that was today's adventure!

Sounds like a great day full of productive hours.
Way to go Kenny.

When does the other plow come?

I forgot to add the 'stroke' of the front lift rod. It's about 2-3/4". I will be able to make the front blade lift using this, but will have to build an assembly similar to the one used for the 54" blade. It will have to be 'heavy duty' due to the weight it will be lifting. So I may have to put this on hold for a bit until I get the 'other' blade here. I'll find something else to do in the mean time.

Good idea with those bearings on the spindles Kenny.

I don't know, how deep you plan on running into the dirt, but

is there any way you can protect them, with a rubber boot.

I suppose lots of grease would work, as long as you're

diligent in brushing it on.

Will, I will do what I can to protect them. I don't know what kind of boot I could find to cover them.

On another note, I played with the rear wheels today. Here's what I started with:

Image003.jpg

A few minutes later, after massaging them with the 4-1/2" angle grinder and cup brush:

Image004.jpg     Image005.jpg

I am going with semi-gloss black insides and Hammered Grey outside:

I'll get the tires mounted in a few days, giving the paint some set up time.

I'm glad I got them from you! They will look very good on there. I plan to swap the tires onto them this weekend.

But Kenny, with the original ones, you could check the condition of the inside of the tire pretty easy. :rolling:

Do you need any pics of an original plow mounted to an FF24?I can go down to the neighbors and snap a few pics of it.
