I saw a video that one of the guys on this forum made. It was on putting chains on an LSXR4100 series tractor (same model I have), and it took him 3 hours to mount them on one side. IIRC, it went a lot faster on the other side when he took the air out of the tire...but then you need to jack up a 5000 lb tractor.
I HATE the things. It took me an hour of hard work to put chains on a Polaris UTV, but they work well once on. Likely the best option.
This will be my first year blowing snow with my new LS and hope I can get by without chains. I have little to no grade to deal with. I currently have an inquiry in at Kold Kutter for studs that screw into tires. I doubt they will be as good as chains but may be good enough for my needs...and much easier to install. My other thought is to put the studs on the rears and use chains on the front tires.
Like you, I see cost as secondary. My issue is wrestling with 100+ lbs of chain on each of those rear tires. Just to old to handle that. Even if the studs only last 3-4 years I will be OK with that. But I do not run my tractor on pavement and put less than 150 hrs a year on it.
I posted several pictures last year about how I install my tire chains, it is a method that removes most of the lifting and tugging.
I can mount a set of chains on 18.4-30 tires in less then half an hour for both.
Also the Euro style many manufactures want them to be installed a bit loose, enough to get a fist under the cross chains with NO tensioners.
Oosik, you wonder whether studded is sufficiently superior to V-bar to justify the price;
most definitely I have run both on hard packed snow, ice, gravel and paved roads.
There is no comparison the studded style Euro type chains will outperform and ride better then any style of traction chain available.
The last V-bar reinforced chains I ran were on two link spacing and the studded Aguiline were twice as effective.
I could stop on my steep driveway with a 2wd tractor and backup, with the v-bar it was iffy to stop without using the blade also and once stopped almost impossible to back up the tires would just spin and chew unless you went into high reverse and used tire speed.
I have switched completly to the studded Euro for my tractors and on the farm we have switched over half the tractors that get chained up over and the others as the ladder chains get beyond repairing. These tractors are used feed cows in outside feed lots all winter with heavy wagon loads with tractors from 60 hp to 125 hp.
To install;
1) lay the chains out traction side up
2) attach a rope to the chains and to the wheel/tire, I just tie the rope to the chain making a V to hang on the tread
3) drive forward pulling the chain up onto the tire
4) stop and arrange the chain evenly on the tire (a second person speeds this up considerably)
5) drive the chain on untill your fasteners are in a convenient location usually have way up the rear of the tire
6) fasten your fasteners and drive a bit if needed refasten
7) keep your fasteners the same distances on both sides, do not have one side tighter then the other
