Lot of Universals run here, allmost as much as Zetors.
I don't know what models are present there, but some of popular models here are:
- 445, 3 cyl (piston dia 95mm), 45hp, mainly 2wd, and 4wd with old DT axle (left side mounted front diff, and left side fwd shaft). A friends tractor clocked over 15000h during 30 years of use. Engine was overhauled at 10-11000hrs (must be original Fiat)
- 550. 4 cyl (piston dia 95mm), 55hp, 2wd, DT and DTC axle. Some of them were blue (Long?) and were known as better quality, but blue are rare. These 550 are known as best models here.
- 530, 3 cyl (piston dia 102mm), 53hp, 2wd and DTC
- 640, 4 cyl (piston dia 102mm), 65hp, mainly DTC, less 2wd
Newer models, with sloped hood are 453, 533 and 643. They have longer wheelbase, 540/1000 PTO and some modiff. done. People usually replace cerrametallic clutch with ordinary organic one at 2-3000 hrs.
All engines have 110mm stroke, 2400 rpm nominal speed, max torque at 1500 rpm.
DTC axles have front diff central located, and fwd shaft under engine and tranny. Final drives are planetary.
Main problem is variation in built quality: you can get troublefree tractor or lemon. Older models, built up to 1990, are known as better quality.
I'm not common with Universal, as I have different tranny on mine, but engine and hyd lift are equal. Engine is harder to start, especially at cold weather, because of low starting fuel quantity (common problem on DPA injection pumps), but they are very cheap on fuel. Engine usually smoke blue, even when new (as on my tractor), as light white damp at crankcase breather.
Hydraulic system is very simple, it has position and draft control- no mixed, draft control sensing is via top link, and is one of best mechanical draft system I used for plowing (even finer than on my new SAME).
I will not hesitate to buy it used, as I know it, and can usually do everything at home.
If you look for Universal, try to find one with 4 gears tranny, with independent pto clutch (lever on left side of tranny). Look for 550 DTC. 445 usually have 3 speed tranny and 2 stage clutch.
I hope that I cleared you something /forums/images/graemlins/smile.gif or confused you totally /forums/images/graemlins/crazy.gif /forums/images/graemlins/confused.gif
Ask Woodbeef for opinion too, but decision is yours /forums/images/graemlins/wink.gif
