YARD TRACTOR | Vintage John Deere 400 & 60 Inch Mower Deck | Initial Repairs & Put To Work

I have 3 JD400’s. That deck fully assembled should be over 200lbs. Nice buy.

I bought my John Deere 400 about three years ago from a guy in Indiana and he told me his nephew tried to drive it up a tree and the only reason it stopped. Was it lost traction because it was almost vertical the only thing wrong with it the nipples were the mainhydraulic fluid line it’s like in square shape tubing underneath or damaged fix those fired up and things been mowing great tractor. I’ve got to tell her for the rear PTO a snowblower never had any problems that I can’t fix on it. Great great tractor.

I love this thing! Hoping to get the blown engine rebuilt sometime this summer. Sadly I suspect that I let the oil run a little too low and one of the piston connecting rods blew. Only one piston moves in/out. Otherwise it’s an AWESOME tractor!

Nice unit, that's a keeper.

I just got a 400. Steering only to right side.. this gives me an idea what is wrong 👍👍

OK, got a question. On the John Deere 400 I just bought. The previous owner had it rebuilt and has been using 15 W 50 oil in it comments? He was told by the builder that he should run that oil in it but I’ve never seen a small engine run that heavy. Looking forward advice on maybe switching back to 30 weight oil Thanks

[@NewMoonRanch]

Hi there! So sorry for the delayed response! I’ll shoot ya straight here: While I have some opinions about oil weights, I’m not the best one to ask this to! I’m sure it’s been discussed extensively on all the tractor forums by guys that have been running these things for years! I, on the other hand, have only managed to blow up my 400’s Kohler engine! And must rebuild this one as well! 🤦🏼‍♂️

any issues with the mower working but then powering out and almost stalling the mower? Mine will work for a bit then almost stall out when I am cutting - I turn the mower off and then it revs back up again and works for couple more minutes but then it happens again - thanks

[@NewMoonRanch]

I haven’t had that issue. What sort of things have you ruled out? Belts/spindles/PTO pulleys? All rotate freely by hand? At the time of the problem occurring?

[@ThatMowerMan]

How many hours does the 400 have?

[@NewMoonRanch]

770 or so.

[@nastynova7632]

What brand of tires are you running on the rear?

[@NewMoonRanch]

The guy I bought it from said all of the ag tires came off of a Kubota. I can look to see what they say on them the next time I see it, if they’re not visible in the videos.

I need a deck shell/cover for a John Deere 400 hydraulic lawn tractor. Can anyone help? Thank you, Wanda Lehman in Maryland

[@NewMoonRanch]

Seems like there’s a lot of stuff like that on EBay.
