Hey all,
I'm hoping someone may be able to help me out before I throw up my hands with this mower. I bought a 2000 Sabre/JD 1438GS 38" last week. I have two acres and have been using a walk behind so believe me when I say I want this thing going! Engine issues were a known when I bought it but everything else was supposed to be good as of early last season. Good news: I've got the engine running. Bad news: Nothing else is working.
Bear with me... I've always worked on my own cars/motorcycles but lawnmowers are a bit of a new world.
Engine:
It's a Briggs and Stratton 14.5 hp Intek OHV (287707). I'm going straight to the starter / frame to jump it to avoid anything in between. I adjusted the valves; the starter was bad so I replaced; sparkplug; etc. The solenoid is clicking rapidly when trying to start from the ignition so I'll likely replace, but for now the short story is that with fresh gas, a shot of starter fluid, and jumping the starter, the engine now fires up and runs like a top. Problem solved! I went to take a victory lap around the yard and here's where i'm now chasing my tail.
Transmission/Brake issue(?):
With the engine running and 'in gear' when I release the brake (whether slowly or quickly) it stalls out almost immediately. I can rescue it if I depress the brake right away. The reason 'in gear' is in quotes is because no matter what gear is selected and whether or not the brake is on still rolls freely, or spins freely if lifted as if it's in neutral. I can confirm that the linkage appears to be engaging the trans appropriately when shifted. Looking underneath while releasing the brake, the engine IS engaging the belt which seems to be causing the stall. No clue what these things could be symptoms of besides a shot trans, but that's the reason I'm asking you fine folks :wink: I would love to be wrong on this but to my knowledge there is no transmission release. I've looked everywhere.
Deck issue(?):
Attempting to either eliminate an issue or discover a new one, I tried to engage the deck while the engine was running and the brake was depressed. since they're on different spindles/pulleys I figured it should engage regardless of the trans. Same issue... It stalls, but If I disengage right away I can rescue the engine from stalling.
I was trying all of this testing while seated on the mower with all four tires on the ground. Currently, I have it jacked up with one of the rear wheels off for access. I also have a jumper attached to the seat safety switch to eliminate a variable while I test this thing out.
If you all have any thoughts I'm all ears! I can take pictures of anything, if needed, as well.
Thanks!
Ed
