SampleManytext.BX owners get sufficient grip in snow without using tire chains. Ballast can also make a difference (e.g. in front loader or filled tires), and use of the 4WD and differential lock. If this is insufficient, tire chains on the rear wheels can make a big difference, perhaps more so on ice. Caution! Watch out for the reduced clearance between the chains and fixed parts of the tractor, especially hydraulic lines which are easily damaged. Keep the chains tight to prevent slack links flailing against fixed parts of the tractor. Depending on the type of tractor it may be possible to flip each wheel around and get more clearance between tire and the tractor.
Chains on Front Wheels?
Owners and dealers disagree whether chains on the front are a good idea. There may be more clearance problems as the wheels are turned for steering. Try chains on the rears first and see if front chains are necessary.
Chains on Different Tire Types
Chains on turf tires work well. Chain on ag tires or industrials (R1 or R4) should be installed so that chains run across the lugs and don't sink into the grooves between the lugs. (Otherwise they'll be less effective.)
Installation
Some people clain it's easier to install the chains and get the appropriate fit by removing the wheels first. Another tip from one owner is to partially deflate tires before installation and re-inflate afterwards. [TBN] Installing tire chains by removing wheels
