1872 - Kohler 28 EFI repower

Thanks for the pics! I like the bracket. With a few squirts of paint, it would look factory!

Thanks Shrew. It's about time I paint it. I initially didn't just in case I needed to modify it

Time for the spring overhaul and upgrades! Over the winter somehow my brake shaft broke in two, easy enough to make up a new one though.


After checking everything over; greasing, changed the hydro fluid and filter (first change after rebuilding everything), I noticed fluid leaking from inlet to the spool valves. I was looking into fixing it when I came across 782CC's post of putting a 3 spool valve on to make the rear lift independent. I decided that was an awesome upgrade and went to work this weekend.
Got the tractor all torn down Friday.



Dual spool valve. Doing this mod will also let me clean up my rats nest of wiring that I scrambled to get finished last spring.



JD 420 valve body arrived a few days ago



Fits pretty good! I'll actually have more clearance between the tank an the valve body with this one than the original dual.


Got a good start on the control handles before my welding gas ran out (Note the booger weld on the middle ) I'll have to finish welding it up on Monday.



I still need to mock up the rear hydraulic cylinder, order a few fittings, and make up the lines going to the rear. Thanks to everyone who has done this modification before and for posting their builds! I couldn't have done it without using the other posts as reference.

Oh and last but not least. Picked up some Tru Powers. All you guys on here posting pictures of yours sold me on them. Plus my property is a bit hilly and this tractor spins a bit in places, even with the added weight. My last tractor had Ag's and never spun. Looking forward to working with these guys!

You will fall in LOVE with those tires, great upgrade!

Looking good. Chances are you will finish before I do. Work has gotten in my way. For my valve plate I added a standoff to set it out a little. Cleared the lever articulation better since that body is thinner. Word of caution. Where I placed the cylinder interferes with the battery. Going to raise my fender pan to clear.
The levers look good. I would have tapered to clear better except I was trying to look stock. Is the picture decieving? Levers look flat not 90deg.

Oh. Not welded up. Doh!
I want those tires....

Yeah, welding isn't complete yet. I'll mock it up on the tractor to get the right angles I want to prevent clearance issues (haha, "right" angles.) I'll mark them and finish welding on Monday.

I planned on putting a garden in and the weather here is finally going to be nice enough next week so I need to get this baby back into working shape ASAP!

Ran into a bit of a snag when mounting the hydraulic cylinder. I found a deal on a 1811 lift cylinder that I thought I could make work. Turns out since I did the cast rear conversion I have even less room than with the aluminum rear. Also, the xtreme 3 point lift arm connection point is a lot lower than the one on 782CC's machine. This is going to be a little more tricky. Anybody have any idea's on alternative lift cylinders? One with a total diameter around 2" would make it a little easier (but with the same capability as the 1811 cylinder.)
