My grandaughter let my Kabota la853 run out of diesel. I have read the directions and, I’m going to try to do it. What is the little pump like thing on the left side of the air filter. Right in frount of the tractor? I seem to have lost the manual that came with the tractor?

Nope. You’re missing something. The tractor is in gear, the clutch is not depressed, the mower deck is still engaged, some safety interlock is active. Check your machine over, you’ll find it!

Vic,
I snagged the fuel line and split it and lost the fuel load. Turning the key won’t crank engine. Is this normal for a fuel line failure? Kubota 3400 with 12 hours!

I have a Kubota B2100, Ive heard a lot about this decompression knob and cant seem to find it. I have bled the injectors without success of it starting. It just turns over and coughs like it wants to star here and there. I replaced the fuel filter and still no luck. HELP.

Thanks, Bryan

I have a Kubota V2203 engine that has water at the injectors when I bleed them. I know I have to drain the tank, lines, and replace the filter. What do I need to do to get the water out of the injector pump, lines and injectors?

Vic, I have an older M7030 utility in a remote location with no dealer assistance available. I think it is a 4 cyl V4000 engine but not sure. I acquired the unit over the phone and later discovered that the previous owner could not get it running either. I have bled the air going to the injection pump but the injection pump will not push fuel to the injectors. The strange thing is that the unit tries to start(presumablly on the one injector that I cannot access with the wrench that I have). I have had the top cover off the injection and everthing looks clean and no evidence of water in the top of the pump. There does not appear to be a bleed screw for the pump itself. Pump plate says that it is a Mccuni precision CAV 503 1000 672590/0979AN 73942F533. I am told that one of these numbers is actually a J but pump guy would not say whether it was the 5 or the 7 that I misread. This tractor has teased me on two seperate occasion when I make the long distance trip to get it started. The fuel injection rebuilder says that it is probably low compression causing the (does not start condition) but I contend that that my be but first I must get adequate fuel to the injectors before I start pulling the engine apart. Any ideas. Thanks for the taking the time to read this. kent

I bought a used Kubota 245dt 20 years ago from a local campground. When I use it, I work it hard all day long – moving dirt, grading roads, mowing with 3 point mower deck. However, between uses, the tractor is parked for weeks or sometimes months. I do not know how many hours are on the 3 cylinder diesel motor. This old tractor (1978?) starts easy and does a lot of work.
My problem:
A steady stream of smoke is pumping out of the breather pipe on the side of the engine. It’s really bad at idle or low engine rpms. When the motor is working really hard the smoke is not as bad. I change oil/filter frequently, which helps for about a day. I’ve never touched the injectors. Do you think the rings are shot?
