The shoulder seasons are rough on track machines. You work in mud all afternoon, the temperature drops overnight, and by morning whatever is packed into the undercarriage has frozen solid. Undercarriage is one of the most expensive wear systems on any track machine, and a lot of winter wear is preventable with a few minutes a day.
This applies whether you run a Kubota SVL or KX, or any other make.
Clean it out before you park it
Packed mud and snow cause two problems. Once it freezes, it can lock up rollers and idlers, so the first thing the machine does in the morning is drag the track across parts that aren't turning. Even before it freezes, packed material acts like extra track tension. That loads up the idlers, rollers, sprockets and bearings on every turn of the track.
A shovel or a pressure washer at the end of the day is the cheapest maintenance you'll do all winter. Some manuals describe raising one track at a time and running it to throw material out. If yours does, follow that procedure exactly.
Park where it can't freeze in
Park on gravel, a concrete pad or planks, not in mud or standing water, so the tracks can't freeze to the ground overnight. If a machine does freeze down, let it thaw or free it gradually. Forcing it with full travel power is how track and drive parts get damaged.
Check track tension after cleaning, not before
Measure tension with the undercarriage clean, using the sag measurement in your manual. Too tight wears everything faster. Too loose and you risk throwing a track. Conditions change fast in the shoulder seasons, so check it more often than you would in July.
Warm up the hydraulics
Cold hydraulic oil is thick. Give the machine time to warm up, then cycle the functions slowly before you put it to work. Pumps, seals and hoses all last longer when they aren't pushing cold oil at full load. Your manual has the warm-up procedure for that machine.
Go easy on the turns
Rubber tracks get stiffer as the temperature drops. Counter-rotating or spinning on frozen ground, gravel or pavement wears them fast. Take wider turns where the site allows it.
Walk around every morning
Look for cuts in the rubber, exposed cords, loose or missing bolts, oil around the final drives and rollers, and anything that looks different from yesterday. A leaking roller seal caught early costs a lot less than the roller, and the idler it takes out with it.
Every machine has its own specs, so use this as a routine and let your operator's manual set the numbers.
