No, I've seen a few pictures of you on your website with your 425.
Just brought it up at the wrong time.

Well, THOSE pictures.... yeah.

Well, a PT425 with operator weighs in around 1600 pounds. It has a lift capacity of 800 pounds, or about half its own weight.

A PT1850 weighs 4000 with operator and has a lift capacity of 1200, a tad less than a third of its weight.

So, its probably easier to nose stand the larger tractor.

What?
Explaination time!

What?
Explaination time!

I'm waiting for that one, too.

A PT-425 is rated at 800 lbs. Unlike most ratings of this type, the machine can actually lift more than 800 lbs. It just can't balance it without a counterweight on the rear, especially if the wheel is cranked over.

I've never driven an 1850, but I doubt that it could lift enough to raise the rear wheels off the ground, unless its hydraulics could vastly overpower the loader mechanics, in which case things would break frequently. Hmmmm, wait, Woodland Farms breaks things a lot . . . . . .

SnowRidge you pretty much hit the nail on the head.
If the 425 is lifting half it's weight or over, hit should be easier to tip.
On the 1850 if it's only lifting 1200lbs, thats a third of it's weight.
For one I'm sure the 65hp Deutz Diesel is very heavy. Probably about half the weight of the machine. Therefore, an 1850 could tip forward, but it'd just be harder than a 425.

It doesn't? I heard that if you center the treadle on a TSM machine it stops.

Very rapidly. Acts like someone hit the brakes. If you are going at full speed, and take your feet off, you will lurch to a stop so fast you can bang your head on the ROPS if your seat belt is loose.

That is part of the learning curve; getting used to gradually increasing and decreasing treadle pressure to avoid looking like an idiot as you lurch your tractor into the side of your pickup truck.

The centered treadle will not prevent the tractor from drifting slowly downhill, unlike the (real) brakes..

Of course the larger tractor will lift more actual weight. However, the statement was "you could do that, but it's probably not as easy as say a 425". Proportionally, the 1850 will tip forward before the 425. It only takes 33% of the weight to tip the 1850 while it takes 50% to tip the 425. The PT425 has a better pound of weight to pound of lift ratio than the PT1850.

It's all in how you interpret the words "not as easy".

Our old IH2500b had a system that prevented that. If you let off the pedal rapidly it would stop, but gradually to avoid tossing the operator. However, it had real brakes, too.

I was lifting a large load of metal roofing off of a truck. The only way to do it was to lift with the arms first (which would not lift the pile) and then curl the bucket gaining a few inches. Because of other things on the truck, we had to do this a few times, blocking up the load each time until it was finally high enough to drive the truck out before the arms leaked down. When i turned, the back wheels came up. But rather than tipping over like in a CUT, you just straighten the wheels and the back comes down.

By the way, I have started taking advantage of the needle valves installed before my lifting cylinders. The tilt one can be reached while on the tractor. So when i need to hold the load for a long time (like when i was grinding and painting a fuel storage tank and needed to access the lower part), I lift with the arms, lock them, then do the remainder with the tilt cylinder before locking that one while on the tractor. The lifting boom magnifies the change in height possible via the tilt and works well. I am also going to try throttling back on the flow through the lines with those valves to see if that gets rid of some of the jerkiness of the hydraulics.

Hi Ken.

Have you considered a cushion valve. I believe it does what you want to do.

The shock occurs because fluid flow is stopped suddenly, so the lowering motion is locked instantly. This causes the shock. This shock has been eliminated with the use of a cushion valve on the front loader circuit.

A PT1850 weighs 4000 with operator and has a lift capacity of 1200, a tad less than a third of its weight.

I can only speak to my 1850, but I think one part of the equation is rear length from the weight. the 1850 is much longer, so the fulcrum is further out, so MUCH harder to pucker than a 425...

Again, just my opinion... I could also have poor lifting ability and not know it....
