After some advise as I'm seriously considering going for a ST270 coming up for auction soon.
20 speed, 7,000hr, good tyres and in good condition overall
I'm currently using a 7140 Magnum to pull a 27' 5000 bar on 9" spacing + 1330 Box
Now it does the job ok but it is at its limit traction and power wise for my hilly fields
So i'm looking at putting the 7140 on sprayer duties and upgrade to a bigger seeding tractor
Would I be right in thinking the ST270 will be a reasonable step up in pulling power, tractor and lugging ability?
224 vs 181 drawbar hp at 5mph according to the Nebraska Tests?
Any unforeseen drawbacks beside the hydraulics?
I've seen a few guys on here have successfully modified the hydraulics so this doesn't worry me to much
Check that you can still get transmission parts. Is it a manual transmission?
I am a bit fuzzy on the detail now and what I am about to say might not be 100% correct. A neighbor had an early STX450 manual. A main gearbox shaft was either not available or the repair cost $50,000 over ten years ago.
The ST270 is about 20 or more years older than the STX450 and they share nothing in common.
The old ST series Steigers are prone to problems in the clutch, transmission, universal joints, hub seals, and final drives. I can expand on any of these points if you want.
Good points - the engines if you get one with a 6 cylinder. The V8's, not so much. They pull well because they are built heavy. They have hardly any plastic to go brittle and crack.
Like anything, depends how it has been looked after.
In my mind, the worst thing is the cabin. The slope of the windscreen and rear window make it a house of mirrors from about 4pm to sundown. Perfectly angled to reflect straight into your eyes. At some times, you can be looking at the real sun, plus have the reflection of the sun that comes through the windscreen, reflecting off the rear window and then reflecting off the windscreen. Sometimes, if you are really lucky, you can get reflections from the side windows too, 3 or 4 sun reflections plus the real sun. Such fun.
