i saw that listing and it is a nice one - unfortunately i've decided to stay with my 3813 - actually just bought a spare complete one to use for parts -
i would love to compare a 4514 and 3813/4213 side by side - when i studied the photos on your 4514 it confirmed a lot of what i suspected. From the photos, It appears they're the same frame/chassis with minor differences. Obviously the shift gate, but that's a changeable component on both our tractors. I noticed the carb intake's been changed with a cast aluminum breather as opposed to mine with a rubber hose going down (way down) under the exhaust manifold - i only notice that as i'm getting ready to replace mine (with all the rubber being 20 years+ old, figure it's better to replace it before it puts the mower out of service. The engine appears to be the same block & cyl at 359cc, so they probably used a higher profile cam for that extra pony.
you've got a nice looking machine for sale - really clean condition - i'll be watching to see what it goes for but i wouldn't be surprised if it goes north of $1000. good luck with the sale
NY Rob - honda built these things like they do the Accord, extremely well engineered and they'll take more abuse than you might think. Not a lot breaks but when something does, it can be terribly expensive - go to Inchman's ebay listing and view the service tickets he posted there, for an example. If you're willing to maintain it yourself, you'll be way ahead of the game. If you plan on using the dealer for maintenance, it is going to be an expensive tractor. That said, that price you stated, if its for the one you pictured, is a great deal, especially if it includes that leaf/grass cart which will be especially useful in the fall. I've been watching them pretty close on ebay for about six weeks now. The 3813s, in extremely clean condition seem to approach $800+, good condition about $600. Seen a couple of real clean 4514s iirc, that sold $950 and $1200, and some nice 4518s, in the $1250 - 1500 range.
You will not believe how nice they perform, run etc, compared to most other lawn tractors. I can't speak for the 4514's deck, but doubt it's any different than my 3813- it will pickup gravel it has so much lift with the standard blades, and that's basically the reason it fills the grass hoppers so well, it moves a lot of air, a lot.
i've had my 3813 since 1990, and have performed all my own maintenance, which still wasn't that much beyond oil & filter changes.
you'd do well to get your hands on a svc manual for it, they can be hand from plano power, or even honda itself and will answer a lot of questions that will crop up. You might also ask the owner for the svc history on that tractor, especially ask if the timing belt has been changed recently or ever. If not, you might want to plan on doing it - they need replacement on cars every 60,000 but on these tractors, i'd think 10 -12 years would be the recommended replacement mark. If a belt breaks while the engine is running, that can ruin the engine as pistons will be going up trying to occupy the same space occurpied by exh and intake valves at the same time. That can ruin a day
good luck with your tractor, which ever you buy
