I believe the 758 is probably the best of the three. I know the 400 has a 2 speed transaxle. You probably mowed in low, which I never do because I keep the grass short. The ground speed of the 400 is above 10 mph but the blade rpm is slow at about 1500. The 455 ground speed is around 8 mph but the blade rpm is 2000. The turning radius on the 455 is shorter as well. A better comparison would have been a 430 for the fact of them all being Yanmar diesel engines. My 430 as well as my 400 will cut a acre as fast as my 757 z-turn. The 20 hp yanmar diesel on the 430 is way superior to the 20 hp Kohler of the 400. I’ve had to rebuild every Kohler engine I’ve had on the 400’s around 1000 hours. Finally put a 23 hp Vanguard on the last one. It’s a hoss.
High capacity refers to the depth of the deck. The deeper the deck the more cuttings can be suspended in the air. The more cuttings in the air the higher volume the deck can mow.
The decks for the 2 newer machines (455 & X758) just sound like the blade rotation might actually be at least 10-15% faster than the vintage 60 inch deck on the 400. (I think this would affect both the cut quality, and the overall cutting speed ??? No...???)
What impresses me is how theres a small but noticeable difference between the 400 and the others, but between the 455 and X758 how little difference there is besides clippings dispersal. I thought the X758 would clearly stand above the others but the 455 is almost right there. It's amazing how well the 455 does despite being a nearly 30 year old design.
the accel deep deck actually did a better cut from what i saw, and i have a 445 same deck as the 455 and i have a 930M which has the same deck as the X758 just mounted different. remove the rear baffle block on all decks no matter the brand and they will all disperse the clippings much nicer.
I have a 2019 X758 that I bought new. I probably shouldn't have it because it only takes 20 minutes to mow my entire yard. I mainly bought it to blow snow. My driveway is 80 feet long. But all and all I just like John deere. I had a 318 for 30 years before the X758. Interesting test. Great job.
Great video! Would have loved to see a 430 in the mix. People always talk about their mowing capabilities and cut quality. I’ve always wondered what cuts better, a 455 or 430? 🧐
The market is really hard to gauge at the moment. Deck, cosmetic condition, and other factors will really determine value. The closest I could get you would be to expect somewhere between $2,000 and 4,000 in most cases. A $2000-2500 unit will have some slop in the AWS joints, cosmetically not perfect, and a 54” or 48” deck.
Given the small amount of grass I had to work with (due to the drought) I opted to keep the X748 out of the test since the 7-Iron is very similar to the HC.
The 4-5 series is great for some applications. I think I mentioned it in the video, but I find my 455 to be the most comfortable overall but my X748 and X758 with 60" high capacity deck will mow circles around a 4-5 series with a 60" deck.
I recently purchased 445 from my neighbor that passed. Pretty new to the John Deere game I do like it but how do you tell there's moisture in the hydro oil?? Sorry if this is a silly question first fully hydro tractor I've owned
A man gave me a very neglected 455 a few weeks ago...I had to rig some stuff up to get it to start but once I got power it fired right up on the first try...Looking forward to fixing it up...Trans runs out well too...
So you mentioned the “super GTs, or at least the designs”, are you not considering one a super gt? I have to say doing research, people seem to think the 758 isn’t comparable to anything relatively new, or even older (in a bad way). I understand the difference between the 748 and 758… is this what you are referring to? Or am I reading too far into it? Just ordered an x758 because I was not happy at how limited my x580 turned out to be, and I’m hoping I won’t be disappointed this time… I can’t imagine the 758 not being able to keep up or even surpass a 748, a 585, a 455, 400, 332, 318… and so on in any task other than FEL work. Granted, I may be wrong, I’m still pretty new to this and am trying to learn as much as I can. Sorry this doesn’t really relate to your video.
I would class all three of these machines as the Super GT’s of their day. The 400 was a very large and capable machine when they came out in 1975 however capability wise they pale in comparison to the newer X7’s. So far I love the X758, functionality wise w/o the loader there isn’t a heap of difference between my X748 and X758. I do have a 2007 X748 meaning it is a MFWD vs the X758 being a HFWD. I find the HFWD much nicer than the MFWD. I think you should be happy with the X758, they are really good platforms.
seen alot of 430H3's for sale lately. if you think the 400 handles like a pregnant cow, pit them all up against an X739. takes some adjusting and train of thought reprogramming, but once you get it, it's hard to go back to the pregnant cows. once you master it, you will just tell every one "nope! not with out my 739!"
What is the blade condition on all 3 decks? Just curious on what it would be across them with new gator blades on all 3, I have a 420, and am repairing/restoring a 425 presently, along with a GX345. All 3 will be getting new gator blades soon. 425 will get them once it's engine repairs are done.
I like mowing my rectangular sections in diagonal mowing passes if they're anywhere close to square sections, then I alternate my diagonal pass directions week-to-week.
Thank you for and I enjoy the channel. The 400 video made me keep them under consideration and I've had one for about 5 weeks now. What I would have liked to have seen up front is a check/comparison on the blades as well. Ideally in a test, they would all start off with new or sharpened blades. Any additional information in that direction (sorry its been 3 months)?
Sorry I did not mention that in the video. Yes, normally I would make sure everything was close to the same as possible. However, we had a drought this summer and by the time we got enough rain to make the grass grow my daylight time for filming was so limited that I just decided to get this quickly one afternoon. The blades were all approximately the same same. None were new. I would say the best blades were on the 455, but I would rate them all a 8/10. The X758 had about 40 mowing hours on the blades, the 400 blades looked very nice - nice enough that when I refurbed the deck I didn't feel the need to sharpen or buy new, and the 455 has about 30 hours on the current set.
Somebody that I used to know add a reply. Period. Eating Nager in the Graystar Nager Nager Nager Nager Nager Nager Nager Nager Nager Nager Nager Nager Nager come inside of me step bro
Can you tell me why the 400 doesn’t like to turn left? I’m considering buying one for my 2.5 acre lawn and I mow counter clockwise so it’s kind of important that it turns left.
For what it's worth I just got a 400 two weeks ago. I did notice the steering is not nearly as tight as newer models. I am hoping that it can be modified in a reasonable manor so I don't distort the look of the linkeges.I do however enjoy this tractor, it has a very smooth running deck and as a whole is an impressive machine.
I have a 425 JD and I have a leak coming down the front of engine. It's hydraulic oil leak falls down on my metal near the front of the tractor any ideas if there is anything hydraulic such as a line? Ty if any knows what could be.
If its a hydraulic leak near the front of the machine the only thing it could be is the steering cylinder. The cylinder and lines are the only hydraulic part ahead of the SCV valve under the footrest.
No the X758 is just a 4wd/2ws unit. Deere use to make the X749 that is 4wd/4ws but stopped when the previous X series ended production in 2013 and they did not introduce an X759 in the US.
They all did a good job and a person couldn’t really go wrong with either of them. I am amazed with my 2038R and the 72” drive over deck. It does a tremendous job. Looks like a golf course when you’re done lol. Sorry I got off topic hehehe
@@jayusher576 I have my 2032r for moving crap around, and my little x350 for cutting the grass for now. Eventually I'll upgrade from the 350. But I can't have anything too big for a mower, since I need to fit around trees.
Handles like a pregnant cow. I love it. Your reviews and demonstrations partially inspired me to purchase my first mower. X758.
Congratulation on the X758, I hope you are enjoying it!

Such a great video, I actually just picked up a 430 a few weekends ago 91 from the original owner. I would really like to see you get a 430
The 455 does an amazing job at choping those clippings. you should do one of these 420, 318, 317. Great video!
What does high capacity deck actually mean? Is that just what they call it or do the blades spin faster like on zero turns.
High capacity refers to the depth of the deck. The deeper the deck the more cuttings can be suspended in the air. The more cuttings in the air the higher volume the deck can mow.

Iv a x740 i run it wirh a 60inch rear discharge deck
the accel deep deck actually did a better cut from what i saw, and i have a 445 same deck as the 455 and i have a 930M which has the same deck as the X758 just mounted different.
remove the rear baffle block on all decks no matter the brand and they will all disperse the clippings much nicer.
Can we see a 430,455 and a 758 together? Be the most comparable I’d think
A 430 would be in the line up if I had one… since this video I’ve sold the 455. Not really set up to make one of these videos anymore
455 will always be the best in my opinion. Had 2 of them, both with 60” decks, 1 w/ AWS, the other standard. Loved them both, a d regret selling them.
Oh
I have an aws 455 with low hours. Am going to sell. Not sure how much to ask.
@@richardtolbert2597 Have you sold the 455 yet?
Still partial to the 400 ❤ great video 💯💪
The 400 is a faster than the rest will go 12 mph the 758 only runs 5.3 so obviously you had it in low range

I can turn my 400 steering with a pinky. Something isn't right with your steering.
Man if you get a 332 and a 430 and do the same video, Youd have my dream collection right there.
I have 455 all wheel steer. It’s got about 1300 hours on it. Any idea what I should sell it for?

Where's the X748? I think it should have been included in that competition.
Given the small amount of grass I had to work with (due to the drought) I opted to keep the X748 out of the test since the 7-Iron is very similar to the HC.
I prefer the John deere 425 or 445 but thats just me
The 4-5 series is great for some applications. I think I mentioned it in the video, but I find my 455 to be the most comfortable overall but my X748 and X758 with 60" high capacity deck will mow circles around a 4-5 series with a 60" deck.
gonna have to hand it to the 455
Looking good 👍 all three but I own a 455 with a 54 inch deck I love it but I have issues with moisture in the hyd oil

Was going to step into the 700 series but with the amount of mowing and yard chores I do I went up to the one series 1025r..and love it
Im getting the 455 the 758 is out of my price range
Ya man! What a cool video.
so the high capacity deck cut just like the 7iron?
Gotta stop first and check out the phone!! lol

It is extremely quiet compared to some of the other mowers I have used.
You can find 430s in maine but good luck affording it...
I think most 430's across the country fall into that category.
Good luck on the 430 hunt, definitely one of the harder finds right now in my area.

No Deere will ever cut as well as the old Simplicity GTs
I have always heard that old Simplicity decks were great. I’ve never used one so I can’t confirm anything beyond what I’ve heard.
I'm just not ready to spend $15k on a mower. So I'd have to give it to the 455.
