Help! Branson Tractor only IDLES - no Power

[Mike1955]

Looking for advice and help on a Branson Tractor Model 4720H..

Long Story short... My fathernlaw borrowed a neighbors tractor right before he was diagnosis with Stage 4 Brain Cancer and apparently it messed up on him while he was using it... He has since passed and now i have inherited the problem to fix.

Before he passed he had ordered a new fuel pump and said that is all that was needed as it wasnt getting fuel

.. I installed it and noticed that the fuel filter assembly needed replaced as well which i also installed.

The problem still is the same... New fuel line, new diesel fuel, blown air back into tank to check if any clogs, new air filter have all been installed. It seems like the tractor is getting fuel but did notice.....

the dpf lamp would flash quick 10 times when keyswitch is turned on.... so i took the DPF filter out, cleaned it, and reinstalled... Still no power, just idles.

Any advice is greatly appreciated!.

Make sur the exhaust is open.

Lets see:
Make sure air filter is clean
getting plenty of fuel
throttle lever on pump is working
no birds or rat nest in exhaust
fuel pump supplying plenty of fuel
engine idles smoothly
If every thing above is ok then I tend to believe the trottle is manfunctiong
Let us know what is the culprit

Maybe loosen up the banjo fitting at the pump while the key is on to see if fluid comes out?

So sorry about your Father in law.
Cancer is life changing for everyone.

My Wife was diagnosed a year ago with stage IV edinocarcinoma.
I’m waiting for her to get done at Chimo as we speak.
Toughest lady I know…..she’s kicking ass and making the most of it.

My 2005 Branson 4220 is doing the exact same thing, getting plenty of fuel to injector pump, move throttle lever by hand still only idles, this started up after sitting for awhile so I may have to take injector pump off as it may be stuck
Reason I posted this I wonder what the original poster found out last year I did not notice anything saying he fixed problem

By the way I changed fuel filter, took off air cleaner, cracked open fuel line at injector seems to have plenty of pressure, took off fuel return line, pump that feeds injector pump provides plenty of pressure, etc just won't rev up still have not taken off injector pump even put in new diesel in tank

Make sure the throttle is moving the arm on the injector pump. Have someone move the throttle lever at the operator station while watching the arm on the pump (with the engine off). They are connected by a cable. It might have broken or become detached.

I thought that's how they were supposed to run,

Seems the tractor idle only problem fixed itself I went out the next day and it started up and ran fine, must have been a vapor lock or something as we tried everything else to get it running
