I don't have much experience on a sled. I did ride one last year for a couple hours tho. It was a LOT of work. I kept tipping over. I didn't realize how hard it is to ride a sled. However it had endless power!
I've got trax on my 09' Rhino 700. They're tons of fun. I did have a learning curve for them and had to modify my machine. I had a lot of clutch/belt issues but have fixed that now by gearing the clutch lower, adding a clutch blower fan and a temp sensor for the clutch. I also have to replace wheel bearings yearly.
They are geared down about 60% so if my speedometer says I'm going 20mph I'm actually only going 12mph, and if the odometer says I've gone 50 miles I've actually only gone 35 miles.
Therefore it does use a lot more gas. I carry a extra gas in the back but have only used it once.
I've never heard anybody say sleds were great on gas either tho.
I have had it stuck two times where I had to dig it out and 1 time I used my winch. Again, it's learning where not to go like down in ravines. The one time I used my winch was because I was on a groomed trail so I had it in high gear and forgot to lock my front differential when I turned down into deeper snow. Had It been in low with the diff locked I think I wouldn't have gotten stuck.
The total depth of the snow doesn't matter as you can see from my picture. A lot of fresh deep powder might be an issue but it will build up a base under it and you can stay on top.
You won't climb steep hills like a sled due to lack of power. You also won't side hill as well since you can't shift your weight like you can on a sled.
However I have gone through sage brush and rocky areas that the sleds with me wouldn't try.
I have hauled out an entire elk in the back.
I stay warm in the cab and have company.
It's time to upgrade and the Honda Pioneer1000-5 should be the perfect machine with it's transmission and 1000cc engine. I do wish it was lighter.
The tracks are the same. All I have to do is buy the mounting kit for the Honda and I can use my same tracks.
Hope this helps!
