valmet 8450

[cosworth]

Any one got one of these?seen one for sale with japwilson looks a good machine 8500 hours thou?what are they like any feedback would be great

Is a pritty big tractor but it will be a rock solid platform. What will be you using it for? I've not driven the 8450 but i have driven the 8050 and the 8400 which are both fantastic. Loads of room in the cab which is a godsend for forwarding (unlike my A92). There nice and big so you can roofmount a crane. Its not got a lot of hours on it in the grand scheme of things and Wilsons are a good dealer.

I will be using it with a botex 11ton trailer and 560tl crane trailer mounted it will doing 13miles one way to the woodland i got should be good with a 50k box was thinking fastrac but iv heard there quite low and abit fragile for what i want it for

My only real criticisms of Valmet/Valtra Valmet/Valtra is they don’t have a perticuly good turning circle, they are quite light on the front end and they are not as heavy as their size may suggest or for their power.

I've never had a problem with the turning circle of the Valmets. I know what you mean about the light front end as i found out when i picked up a big side arm flail once.

 

40kph is pritty bumpy in the Valtra and god help you if you hit a bump and your not wearing a hard hat. Wouldn't want to be at 50kph. The Botex 560TL is a fantastic crane. Got a 10 tonne Botex which is a little old now and will be replaced with another 10 tonne botex with a 560 or 570TL.

 

I would seriously suggest getting it forest guarded its an extra couple of grand but it worth it. I've come very close to putting a log through the side window and its good to know the guard it there just in case. Especially when stacking close to the tractor. The belly plate saves a lot of damage too and the brush bars save many wing mirrors.

 

Never played with a Fast track but i can see the appeal especially with the new 4 wheel steer one.

front weights !!!!!! isnt that what ther for ? keeping the front end down when carrying implarments

err yes front weights are for keeping the front end down when carrying implements, BUT the Valmet/Valtra Valmet/Valtra have the front axel set back further than most to get back some turning circle by shortening the wheel base, this means the front wafer weights dig in on transitions from slopes to flat ground or in undulating terrain sooner than most others, they also restrict turning between vertical objects due to the way the front end is quite forward of the front axel, if you go for front lift arms and a weight block turning between vertical objects is even worse.

 

Front weights, front lift arms and weight blocks &/or long front overhangs are fine in fields the native home of tractors but woodland, forest and undulating axel crossing ground is a little different.

when i had my valmet i had a roof mount 560 tl crane and i had to have front weights put on, even with water filled tyres and forestry guarding it still bounced like a hooker on my lap.

A good solution to this would be to ballast the front tyres, or look at having the front axle weighted

True, front wheel ballasting with water would add ~190kg per tyre or ~380kg total which would be as affective as ~250kg of wafer weights on the front, the trouble with wheel, axel or belly ballasting is there is no weight transfer between axels as a result of the extra weight added, weight that is forward of the front axel effectively removes some weight from the rear axel and transfers it to the front axel in addition to what the weight imposes anyway.

 

The above said any weight added to the tractor a percentage will be converted into traction in 4wd dependent on the percent adhesion the ground offers just as percent adhesion vs. mass will denote the tractive effort and the speed at which maximum HP can be used, but haling a trailer by road vs. haling the same trailer around woodland/terrain means there has to be a compromise I.e. for the road you need higher power and less weight in your tractor, for woodland/terrain you need more weight in your tractor and optionally less power.
