John Deere SST16 Lawn Tractor with 16HP V-Twin Briggs Engine

[mondo78]

The SST didn't last long about 3 years and it was discontinued. The ZTR mowers pretty much replaced this unit. It was innovative and won awards but didn't sell very well in the long run. Still it is a John Deere and that ain't bad.

mine has a surge and will die if I don't pull the choke out sometimes. I noticed the hoses to the fuel pump are hard as rock. Since these pumps run off vacuum, could the vacuum hose be leaking? it does it when it is warm, runs ok cold.

[donyboy73]

@msta999 i would clean the carb and replace those fuel lines first

[msta999]

@donyboy73 I replaced the pump, hoses and cleaned the carb bowl. It is still surging. I did notice the fuel filter never fills with fuel, looks like none is in it. I removed the fuel pump and put some vacuum to the air port and the filter started filling. Could it be it is just not getting enough pressure from the engine?.. only guessing here. But I am assuming the filter should show gas in it. If you pull the coke out 3/4 way out, the surging stops.

[donyboy73]

@msta999 make sure the impulse line is on tight

[msta999]

@donyboy73 It is on with the clamps. This JD hasn't been used very much. There are no oil/air leaks that I can see......

Am I correct in assuming the fuel filter should look full?

[msta999]

@donyboy73 I did, it has clamps on both ends and is a tight fit. Still surges. I'm wondering why the pump doesn't pump more. I can blow though the fuel filter just fine. I think I'll replace it anyway.............

[msta999]

@msta999 I got it!!!!!!!!!!! It was the same problem you had. This time I pulled out the switch and watched it when I turned the key on and nothing was happening. (I did have it grounded) I worked the switch by hand a bunch of times and then it started working. Put it all together and it runs like a champ! Thanks for you help and your video.

[Sagina1999]

Nice Video! I had a steering acuator go out on mine. I love mine!  It has a surge now at idle, but sitll runs good. If the battery goes down you can't steer either! Be good.

[strassj]

shame they dont product of those anymore.

But I rather to take different kind of zero turn tractor.

[dirtshower250]

dosent have enough deck for that power

[231MasseyFerguson]

Great videos! Do you ever work on zero turn radius mowers? What about V-Twin engines like the Vanguard Big Blocks? What about Kawasaki engines? I have a 31 hp Kawasaki FX850V twin cylinder on my Hustler Super Z ztr mower. Have you ever worked on this engine before?

You Sir, Are THE Man!!!!

[donyboy73]

@231MasseyFerguson i've ner worked on ur engine but i have on kawasaki fh540 and twin briggs

[axesbowledaslove]

Just want to say thank you for the video. I bought a used SST16 this summer and find it perfect for my tight-quarters lawn. Now I will know what to look for if I ever see a fuel starvation/failure to fire problem.

[thumasta666]

so these engines do not have a float on the carborateur ?

[donyboy73]

@thumasta666 still have a float

[1972FordF150]

I was wondering what those things were going in to the carb bowl.

[GarrettJDB]

i love vanguards and wow is that ugly. great video don!

[boat6868]

You've got it running beautifully.

[donyboy73]

@boat6868 thanks

[ringbolt9]

cool .. how does it steer? the rear wheels? since the front wheels just move free with no tie rods or anything

[donyboy73]

@ringbolt9 yes steers with the rear wheels, kinda like an excavator

[ncrdisabled]

Wow you get to work on the neatest toys. How did you find the problem that caused the fuel stopage?

On a different note is it possible to adj the valves on a 1991 18hp briggs non OHC engine I took out the plugs and the starter turns over great with plugs in very slow turnover I learned the trick from one of your vidios but you did not mention

non OHC engines. Mine is the 18hp twin

Thanks

[donyboy73]

@ncrdisabled on non ohv a slow turning engine is usually not due to the valves. check ur battery, starter and cables

[canadaeast]

Is John Deere a good brand when it comes to lawn tractors, I am shopping around for a new one. Any suggestions as what is good and what is not ?

[spitzification14]

how fast is it can it do 100kmh is it modified for racing

[donyboy73]

@spitzification14 probably

[Dodgeboy2003]

I am impressed with that huge tree in your front yard. Could you give us a better shot of that tree? It isgorgeous!

[gpzDave]

that engine is the best lawn tractor engine I have ever used, never uses any oil ATALL

[Mueiwark]

Never seen that type of ZTR tractors before. I just looks like a regular tractor.

[th19940305]

[VE9REJ]

[snaponjohn100]
