Congrats! Nice tractor!
Where are you going to put the bucket?

Congrats! Nice tractor!
Where are you going to put the bucket?
For FEL I have 3 implements. Original forks & bucket
But snow blade is different story. Because it looks way better than YM original, that one I have ordered that one from Finland - Compact Tractor Snow Plow | HillTip SnowStriker™ Tractor snow plow
Finns will make it fit to YM unique FEL design. They were quite pissed, as YM didnt provide any drawings of FEL attaching points.
Frankly speaking I really dont understand, why FM is doing so. First - why to make unique FEL interface. And, ok, maybe for some reasons, just maybe, but why then make obstacles to those which are going to make attachments, for your system ??!!
Anyhow - dealer was very helpful with this. And they are going to make 3-rd function for FEL as well


At the end of the day - I will have 3 implements, all with YM "interface"

Wanted to have broom as well, but hydraulic oil flow is not enough to turn it, so brush is going to rear PTO

Frankly - FEL capacity is a bit of disappointment.

That chunk is only 2,4 m long. Aspen, which is light wood. OK, directly from stump, could be full with juices, but it is "winter cut" = should be pretty dry already

Maybe some weight on rear 3p will help. Guys - do you have any idea, how much would be optimal to put on the tail ?


Turf tires in that snow / ice are working very well, indeed

Didnt like joistick, little jerky to my taste. Please get me right - it is a kind of proportional, but I would like to have it more graduate (if that is the word).


Other things are super

Seats safety trigger is overly sensitive. Boy cant ride it alone. For him that is massive disappointment.

But I mean, I will not bridge that. At least for while.

From the photo, it looks like the FEL capacity is still unknown. There is a problem with a lack of weight on the rear of the tractor. That's common to any tractor.
Actually hydraulics started to struggle either. Both lifting and tilting. Only noise changed when joystick was pulled. 😬

The backhoe makes a great counterweight, and I think the FEL is pretty capable for a machine of this size.

Are you operating with the engine speed at above 3000 RPM? Increased engine speed = increased hydraulic flow.

I dont have BH. Just dont need it. I have BH on bigger tractor, but already few years it stays put.

now I am planning counterweight. I mean around 200 kg should do the job. BH is ~ 300 kg

Nope. As tractor is new, I don't turn motor above 2000 rpm
Maybe that's wrong, but I mean: rpm = flow = speed of hydraulics
At the end pressure should be the same, not so much relevant on rpm ?

That is how the theory works, but without flow you do not create pressure. I fully understand the flow=speed and resistance to flow=pressure. Without flow, it will minimize resistance. When doing a pressure test the engine is to be set at rated engine speed, anything below that will have drastic differences.

There is no break in period for the engine, just a initial 50 hour service.

NICE tractor!
If you don't run the rpm's like 2500 up
don't expect the functions on the tractor
to work very good! example: your trying
to use your tractor like a little boy and he
can't do the job until he grows up! You
need more RPM"S that's what the tractor
is made for you are not going to hurt the
diesel engine with high RPM"S so you will
not be using very much fuel with the high
RPM"S but you will be able to work better
also without weight in the ass end filling the
bucket with put you up in the air, you get
a free lift in life not good!

Those are original lights

New LEDbar in action.

Maybe should be a bit higher. Will see.

Good thing is, that light is very focused.

And working lights for backside

I am super happy with result.

What lights did you upgrade to? They are definitely effective!

There are some break-in suggestions in the "Operation Manual" on page 8-2. Some of them make sense, but others are not really practical, like operating at low speeds for the first 50 hours, and avoiding heavy operations. I didn't have 50 hours of light work to do. Then the manual states that you should use the break-in procedures for all tractors regardless of age "to prevent premature tractor breakages and accidents." Thanks a lot. Not why I bought the tractor.

Enjoy your new SA424!

I didn't bother with the breakin thing as you need
to run your tractor rpm's high its what it was made
for and the way they make engines now IMHO you
don't need a break in period as I have the regen system
and if I run low rpm's I would be regen'ing a LOT!
Tractors are made to work hard with high rpm's
AM I WRONG???????
