A couple 5400 questions

[EhM8]

The 5400 series stacks up well against the competition on most fronts, but I was surprised to notice that it's turning quoted turning circle for the 5455 is 8.4 metres. Funny thing is, I have heard the CNH TLA and JXUs criticised for having a turnings circle of 4040mm, but never heard the 5400s criticised in this department, even though the turning circle seems twice the size. Am wondering why this would be - longer wheel base maybe? Have you notice the turning circle being a problem at all? Probably wouldn't matter for general field and loader work, might be a bit annoying with a 3 pl boomspray.

The 5435 is great! Had it just about 2 years, Mostly just a baling tractor, but I did do some brush mowing and we spread manure with it this past winter. It was a little more than needed at the time, but got a great deal as it was a leftover, demo tractor. Bought it to use for a few years then trade for a bigger one with a cab, but now I think i'll hold off and keep this one and just buy another one. The weight on it is awsome. For a 60 PTO hp tractor it has the heart of a 100 hp tractor. The dyno says it's a little more than 60 too. I used a MF 481 to bale with and it was great, untill I drove this 5435. Maybe a little overkill for the need but the absolute best tractor ever to run the fields of this farm.

I'm not sure where you found that number. The owners manual for the 5455 lists the turning radius at 4.33 with 14.9R28 and 4.52 with 16.9R28 tires. Max steering angle is 55 degrees

MF 5400 - 5455 brochure.

Sounded strange, that is why I asked. Seen it printed in a magazine too. Maybe it is a different way of measuring turning circle :S Or an error, wouldn't be the first anomaly I've seen in manufacturer brochures.

Turning radius is not even listed in the North American brochure and is buried in the owners manual. The numbers quoted though are for the outer tire radius without brake.

I think it's just that one is looking at turning radius and another is looking at the turning circle or diameter which should be exactly twice the radius by definition.

Gah, that is so simple, it didn't occur to me! Comparing tractors is tricky!
