BEAVER: Need Help! Just will not start

[Arkie Jim]

Have you checked for dirty injectors....you can have plenty of pressure, but if they don't spray it is very tough to start....I had similar issues, with the white smoke etc....the tractor had sat for some time and the cleaner did the trick...worth a try anyway. Good luck.

Sorry you still having problems starting the Beaver. Question??--Have you used any ether to start this tractor. How long are you heating the glow plug. The manual suggest 20-30 seconds---My Satoh--I have noticed it takes a while to crank when I rush the glow plug heating, so I now allow it to heat pretty good before I start it. Diesel has to get hot before it will burn so it may take a few cranks to get it started. The hotter the fuel gets--the better my Satoh runs. Mine runs great after a couple of hours--These little tractor will work great--need to watch your water in the radiator--mine uses about a gallon after 3-4 hours of work.
I am not an expert on diesel fuel but some is for hiway use and some is off road---Sulpher is in the off road fuel but I ran it in mine--no problem.
I can suggest one thing---Fix it and keep it---Mine I love it and it is a great size for my landscaping and garden work. Keep the chin up--I will do some checking and see if I can relay some advise.:thumbsup:

If I read your comments correctly, you are getting compression pressure in your crankcase or "blowby". This is probably due to a cracked piston and would certainly cause the no start problem. First, get an accurate measure of compression in each cylinder. Use a diesel compression guage and a 10mm adapter in each glow plug hole. Factory spec is 455 lbs. Anything less than 350 indicates a problem. If you have a cracked piston there will be a significant difference between the cylinders.

If you want to discuss your results, call us weekdays 1-800-609-5110. We can furnish parts. Bill - satohparts.com

Take the glow plugs out and check compression. The compression should be 425-455 Ibs. If it is under 400 take it apart and put rings in it and check the valves.If you need parts we can help

ok your problem is not clearly stated.all you said is you changed the tractor head gasket and the tractor would not start.then you asked if there should be pressure in the valve cover hose.no there should not be any hi pressure there.
1. was the timing set correctly?
2. what is the temperature where the tractor is?
3. did you put a block heater on the tractor?
4. did you check your compression?

check the electric fuel shut off it will be on injection pump its simple to check have somebody turn the key on and off if its good you should be able to hear it click if not theres 2 ways to fix it.either replace it or take it apart take out plunger and seal then adjust thottle linkage where when you thottle down it shuts the motor off . and it will never do it agian after you remove the plunger you will have to put the hollowed out switch back on so it wont leak i got ahead of myself. charlie

Beavers don't have electric shutoff.

Beavers don't have electric shutoff.

Beaver is a Mitsubishi, or the later models are, and for sure and the MT160/180 have electric shut off as well as a manual shut off capability.

It might be possible that the greys don't have that feature but my MT180D sure does.
Now it is possible that the electric shut off is a USA compliance that is not on the greys.

As an added safety feature I enabled my manual shut off using a simple choke cable.

My parts manual also shows a whole lot of minor complience items for various markets.

After my Beaver got over heated (loaned out) it would not start. What happened is he overheated it and scored a piston causing low compression on one cylinder. It would try to start on one cylinder that had good compression but would not.

The original poster stated that his tractor was a S-370. That makes it a Satoh. The Satoh 370 was made from 1976-1981 at which time the S-372 and MT-372 started. I still don't think the 370 had the electric shutoff. If I had to guess, I would say that began with the updated 160's and 180's.

The S370 is manual shutoff only. My S370 was sold in the USA and is equipped this way. I can take the key out and put it in my pocket once the tractor is started.
