Oh right. Are they problematic enough. Do they pull Well with their original perkins engineFrom what I remember of the 1200 it tended to run out of power before traction. I guess to much through and something will break. I snapped the main drive coupling pulling a small earth scraper box. That was relatively easy to replace.
TBH I drove one occasionally on the farm when I was student. It had been the main cultivation tractor from 1975 to 1978 then 2nd after they bought a 1505. It was very usable at about 5 years old when I drove but it seemed quite tired and rattly. I cannot rember the hours but I guessing not particularly high by modern standards. It did grip well and the 6.354 chucked a lot of soot out when working hard.Oh right. Are they problematic enough. Do they pull Well with their original perkins engine
Was the 1200 not known for machanical failures even with the 6354 Perkins let alone with a possible 200hp. It’s only a 590 diff and rear axle
What about the 1505. Would that handle more power from a TM engineThe axles were mostly the ones fitted to the MF 185 or similar. Not the faster running diff ones with the larger final drives found in the 595 and 4wd 590 models. So 110hp is about their safe limit and, personally, I would not want to put more than a 120hp engine and 500Nm torque in front of a MF1200 driveline.
Fairly sure that my tier3 MF5445 would outperform an MF1200 if both were factory standard specifications.
No doubt. As long as you remember that they are as rare as hen's teeth in the UK and were designed and built mainly for fast top work pulling wide shallow-working implements by the drawbar. For prairie farming. Not heavy tillage.What about the 1505. Would that handle more power from a TM engine
Your choice of course but you said in your op you said “I need the power and traction for pulling heavy loads up steep hills”.Nah.i want a vintage articulated tractor that i can swap the engine for a TM 7.5 litre engine into it fir extra power and torque.
Me and my late father fit a 1006t from a bin wagon to an mf 2620 replacing a 6354, fit fairly good just a few mods, fudge me it had some power then around165bhp+ you could go up steep hills on the road with lightish loads in top gear and it did 45kwhy not fit a AT6 354.4 engine or even a 1006t as in mf 8130 ? save alot of work making a back plate, one has been done on you tube
MF officially sold the Opico turbo kit for a while and it was even featured in their pocket catalogue in the late 1970's. This was before TB turbo's with their superior, more suitably small turbochargers were ever thought of.Don’t think either the 1200 or 1250 ever had turbos fitted by MF. But a fair few had Opico or TB turbos added by operators.
