My new JD 4720 w/R-1s had trouble getting around in the woods through deep snow in Vermont. It was fine keeping my 250' drive cleared and I had no trouble blading some deep stuff, but when I ventured out onto my hilly trail, the wheels started to spin once the snow started to pack up against the axles and under the chasis. Going straight and flat was not a problem, but trying to go uphill or turning was very difficult. I had my loader w/grapple, 650lb rear blade and rears are loaded, so weight was there but tires would just spin. Snow level was 30" average with some deeper drifts. Top was crusty and a little wet under the surface and then some lighter powder at the mid to bottom. Even when I hit ground with the r-1s, I was pulling up soil with no progress...turning had to be done carefully as the smaller fronts just wanted to go sraight and push more snow.
I talked with a few farmers locally who siad they were having trouble getting to their maple trees with their large ag tractors much bigger than mine and a logger told me he was even having trouble his tree skidder with chains on all tires. Anyone have any suggestions on whether chains would help or is it just a fact to live with?
(I also have a Polaris Ranger and it was useless unless I rode in 4720 tracks where the snow had been reduced down...otherwise the bottom skid plate rode up on top and the wheels just spun. It sure was great for snow machines!)
