You need to set the seat weight about 10kg or so more than you weigh, or just enough so it doesnt bottom out most of the time. Setting it at 130kg or what ever is too stiff. I weigh about 85kg and the seat is set at around 95kg.
Below is a photo of where my deck springs are set. I have about 1.5" more for adjustment. How much do you have? Try adjusting that nut all the way to the end, both sides of the deck. If that doesnt work ask your dealer about shortening them. It will be a pita to do so let the dealer do it if you go down that road. May even need to find a shorter and or weaker spring. I would not take them off altogether!
Get yourself a low pressure tire gauge. Unless your dealer used one, you have no real idea whats in there. Last time I let my dealer level my deck they set one tire up around 24psi and the other 18 or so. I asked for 10psi. Dont even get me started on all that though!
Try holding the levers further down, like around the first bend. That will give you less leverage so therefore probably less chance of jerking. Also, use a lighter touch.
The above should sort your forward/back, up and down but going front on over ruts like your doing in the vid will be rough no matter what machine of similar size, Ferris excluded.
How did those ruts get there? The place has either been mowed in both directions or possible circular. Seriously try a different direction. Think of the union jack with the 4 different angles. Doing angles doesnt add much time and Im sure youd be able to make it up with a faster speed. Next time you go over a speed bump, try hitting it at an angle. Its much less severe then hitting it front on as only one wheel has to absorb the shock at a time.
Id like to see vid of you driving the Dixon over those same ruts. Id also like to see a side by side comparison of speed between the Dix and the SZ. I wonder if your actually going faster than you think.
Below are a few pics of a property I just picked up. I DID NOT do whats in the pics. I got the job because of it. Every one of those lines is a rut from being mowed in the same circular direction for god knows how long. The terracing is insane. Point is, no way I can get any real speed on this place as the deck will bounce badly and is really not good on my back. Point is, I know its rough so adjust my methods accordingly.
In the video with my back not on backrest, this was taken on a much smoother lawn, I didnt actually take a video of that on the same property which I should have! Taking my back of the seat rest is a help for sure, but doesnt fix it maybe 50% better. Also I end up with a sore lower back at times as some lawns are rough for a large percentage of the time, I guess all I can do is think back to my old mower where I never had to do that, and buying this hustler i expected a smoother ride, even tho i may need to accept this is the case it is still upsetting.
I will measure the springs tonight, im going to back them off all the way so no adjustment is left, hiopefully it will improve enough. if not then I will enquire with dealer about shortening springs, or buying some smaller.
Today I went back to the lawn which the videos are in, I honestly tried more than once to go over the same bumps without hands on levers, also with hands low on levers, it didnt help the hydros still seem to do their thing whether my hands are on them or not. I realise in the video I was moving the hydro leavers with my arms during the jerky movements, but this was an extreme case, when im out moving all day im obviously not bucking around to this extent all day, so im not moving levers with my arms, that comes from experience. but i do get the uncomfortable jerkyness even at very slow speeds.
I would definately like to get the old dixon out to the property and do a side by side comparison, I will do when I am able to but its a difficult task so not too sure how soon. In the mean time I am confident in myself that im not goign as fast or atleast no faster over these bumps than I did on the dixon. In fact while the hustler was in the dealers that lawn was due for a cut, so I had to take the old dixon out there and in comparison just didnt have a bad ride at all. I get the up and down bouncing like crazy over those ruts, but never have any jerkyness on the dixon. Anyway taking on board al your suggestions, so will see what I can come up with. I can try going a different angle on that lawn, but as I say I am getting the rough ride on all of my lawns not just this one and changing angles will not help in all situations.
