That's a nice looking 825.   My first cab tractor was an 825 Belarus  with 600 hours and a Memo loader.   Had it for 2 months before I found an 8345 with 200 hours and a Koyker loader.   I now have a 1220 MTZ. and the other older models.   they are great tractors at a good price.  If you need any help, the forum will  have what you need.  Parts are available and take about a week to get to me in OKla. 

Welcome to the forum.  BTW once you get used to a cab, you won't want to drive those other tractors

MTZ Tractors - Current Models / MTZ 1220.4 Has plenty of power
« Last post by damengineer on May 17, 2018, 12:33:15 AM »
Put the 15 ft Rhino Bat Wing mower on the 1220.4 a couple of weeks ago.  I had about 100 acres of old prairie bluestem, johnson grass and clover that was 2 years old.  It had fallen and was about 2 ft deep and thick.   The 1220 went through it like it had nothing behind it.  I was traveling about 4mph in order to mulch the grass as best I could.  Ran about 6 hours and cut over 30 acres.   

The only ergonomic objection I have to the tractor is I cannot get the seat back far enough to suit me.   I run with the seat on my New Holland TS110 nearly at the back glass!  I am 6ft 1in tall and weigh 325lbs.  After the 6 hours of running with the close up setting of the seat, my bad knee and ruptured discs gave me fits for the next day.   

I had an air seat suspension bought for another tractor.  It has the air control on the front.  I mounted it as far back as it would go on the bracket from the original seat.  Then installed 2x3in steel tubing between the seat and the suspension to raise the seat farther.  When I get the seat where I like it, when I hit a rough place, it hits the partition in the back of the cab where the batteries used to go on the earlier models.  The 1220 has the batteries under the hood in front.     I can cut out the partition and move the seat back at  least 6 inches.  If I did that, I could remove the tubing under the seat.  I nearly hit my head on the roof now in the case of hitting a really rough spot. 

I cannot find a manufacturer that lists a seat for the MTZ or even the Belarus.  Ian at Higginson sent me a file of a seat that they use to replace the original, but it was a .dat file and I cannot open it.. 

Anyone had any experience with either opening a .dat file or changing seats.   At $500 and up for seats and suspension, I don't want to start throwing money at it without solving the problem.  I have to solve this seat problem, or I cannot sit on the tractor much without damaging my already pinched spinal cord... 

My only objection to this tractor is there is a large difference in the forward and reverse speeds when using the range selector as a shuttle during loader work.  To keep nearly the same speed in forward and reverse,  both gear levers have to be changed.  1st gear reverse is about equal to 4th gear range I in forward.   The range shifter is not synchronized, but the gear selector is.   The dual plate clutch has a lot of momentum built up and without a clutch brake, there is a lot of gear clashing over 1000 rpm...  For most operations it is not a p;roblem, but when using a loader, it is inconvenient.  However, I had a full bucket of dirt and an 8 ft box blade on the rear, and it handled the load with no problem without ballast in the tires.   It is truly a well balanced tractor.  A heavy one too. 
Even with the inconveniences, it is a good buy for a 125hp cab tractor.

You can buy the parts or a kit to rebuild the pump and I've seen nozzles for the injectors.  In the world of diesel fuel injection the parts are pretty low cost  might not be worth it to try and rebuild them.  However if you like as mentioned you can get kits/parts. Just contact MTZ .Contact us: Email: spares@mtzequipment.com     Fax: 647-933-9066     Tel: 1-855 2GO-4MTZ (1-855-246 4689 x222)

Or there is that fellow on ebay that offers and ships over all kinds of kits to rebuild stuff.  https://www.ebay.com/sch/harp2rs/m.html?item=181284965388&ssPageName=STRK%3AMESELX%3AIT&rt=nc&_trksid=p2047675.l2562

Search youtube for 250as injection pump rebuild there is videos.

As for removing the injectors its should be straight forward.  Post a picture if you like of what you got there.

Maintenance - Service & Repair / Re: 420 injector nozzle removal
« Last post by RjMaan on May 04, 2018, 11:39:25 PM »
I think you are right. There are some serious issues in your 420 which was the main problem behind its low power output. I think you should get your desired manual from Repair Loader. I have heard that they have a good reputation when it comes to manuals.
