- whats the lifting capacity on the sleve hitch/stock hydrulic system ? How much weight can I hang on my plow? (i repaired the bent lift arms last night, gave it all a coat of paint and added some new grade 8 hardware...

- the little plastic fan on the driveshaft... how important is it? it was fine the other day, but while I was plowing today it must have broken from vibration.. maybe it was brittle? idk... I made a pass and came back and there were peices of it in the dirt...


lastly, i spent about 30 mins plowing the garden up today... ive still got a little okra coming, but man i couldnt be happer with this little tractor!! Now I need a turn plow, a box scrape, a set of discs, and a tiller!!! haha!

thanks in advance guys!

The lever on the side of the tunnel cover is used to release the manual hydro valves so that you can push your tractor around if needed. You might want to remove the tunnel and see if you have manual or automatic valves. Each of the manual valves will have a button on top to push down. The auto valves will have nothing.

The limit of the rear lift I want to say is @ 300lbs. but I am not 100% sure about that. Someone here will know for sure. The fan is needed to help cool the hydro pump. The pump is aluminum with cooling fins on top and the fan blows air over the fins to aid in cooling of the hydro fluid. In my opinion I would put a new fan on before doing a lot of plowing or working the 149.

where can I buy that little fan? i wish i know why it broke?? it should be aluminum. plastic sucks!

They used aluminum in the early model cubs but went plastic. It probably broke because of the age and it was brittle. If you think about it, it was over 30 years old before it broke... That's pretty dang good, LOL. You can pick one up at your local dealer or our sponsors up at the top of the page will have one. Also since you will have your drive shaft out, I would go ahead and put in new flex joints too. Then your drive shaft should be good for many more years as long as none of the spiral pin holes look worn. You do have the service manual for the 149? If not it is located in our GT library.

Not familar with your 149, but you might want to look @ the lift arm to see if it is hitting the fan when lifting/dropping, while you have the tunnel cover off.
I've heard of them getting broken because the lift arm hits them.

You don't need to hang ANY weight on the plow...if you do, you have it adjusted wrong.

matt,

im not useing a turning plow... its some sort of cultivator plow.. it weighs maybe 50 pounds? and its short so i dont have leverage on my side.. if you think you can adjust it to dig in hard packed dirt with no weight please come educate me....


if you dont need weight why did you put a huge weight on that turning plow you restored? :bigthink: do you have it out of adjustment?

ill check that in the AM... it just seems strange how it broke just all of a sudden. thanks!

That would be a gauge wheel and not a weight my friend. :bigthink:

Correct.

You said you had a plow, not a cultivator, so how was I supposed to know what you meant? Yeah, a cultivator is probably going to need some weight. The 3-point and sleeve hitch are probably good for ~250# safely, but you won't need that much for a cultivator.

Weight on plow ?
 

" if you don't need weight why did you put a huge weight on that turning plow you restored? "

I'm guessing that what looks like it is a heavy weight in Matt's photo is actually the plow follower, which is a hollow steel wheel, probably around 5 lbs including its arm and bolts:HeadScratch:

I've never weighted a plow, but it is common to weight a disc and/or a harrow.

Your 149 looks like a nice deal. I agree with DX3 that I would replace the fan before too much more fun is enjoyed.
:beerchug:

Allen We need a pic of what your talking about to make sure.

:TTWWP:

nice cultivator .....

I agree! Love to see it in action. :beerchug:

While you have off the tunnel cover, pay close attention to the rear joint of the drive shaft. I am restoring a 149 myself, and the driveshaft in them is one of the few short comings on these tractors. I am replacing mine with a QL shaft, much sturdier and a lot cheaper for replacement parts.

Since you just lost the fan, look at the rear coupler on the driveshaft, there is one flex disk there that could be going out, also there is a small pin on the back of the driveshaft that serves as a locator for the driveshaft, it slides inside a hole on the coupler that is attached to the hydro pump....it is maybe a 1/4" pin, yours might be worn badly, or be even completely gone. In either case, even with a good flex disk, it might allow side to side movement of the rear of the driveshaft which caused the fan to contact the lift rod for the sleeve hitch, there is not a lot of clearance between the two.

I believe the service manual says to you need to unbolt the engine and slide it forward to get the driveshaft out, on mine, I was able to remove the two rear motor mount bolts and loosen the front two, then I was able to rock the engine forward to remove/ install the driveshaft...of course I was using a QL driveshaft, so that might make a difference. You will also need to pull the pin out of the rod for the PTO engagement rod as well to let the motor rock forwards, either way, you will have to remove the driveshaft to replace the hydro fan. You can get them from any of the sponsors as well as you local cub dealer, should be less than $20...Good Luck!!!!

thanks for the pointers. I ordered a new fan and some flex discs. we'll see how it goes !! ill keep you posted.

fan wear
 

The fan on my 149 is worn down to about the size of a golf ball with points on the ends, with the tunnel off it looks like the lift linkage would come real close to it if it were whole. Can't find a pic, i'll get one later.

I checked the fan on my 147 today and it is aluminum. Just FYI.

That was the last series of tractor to have an aluminum fan. All after that were plastic.

So I would assume all narrow frames are aluminum and wides are plastic right?

Yeah, and I think the replacement NF fan is also plastic.

The one for the 125 was.

Also the 147(so assuming all narrows) has a metal collar on the outside of the fan to keep stuff from hitting it I guess and probably help with airflow.

I think I need to replace this
