Sorry Lance, I tend to let experience colour my reading of others thoughts. You are correct. I use a LT for mowing duties on the flat properties in my neighbourhood and a heavy FEL equipped GT for snow duty. While the LT's hydro possibly won't make enough torque to spin ATV treads on grass, I flat guaranty that any GT hydro worth the classification will if the need arises where more torque is necessary.
One of the tasks assigned to my GT has been to back a 4000 lb travel trailer across the lawn to its parking place. That is maybe not as traction intense as dragging a truck backwards, but it still requires substantial torque to turn it 90° to the driveway in a limited space and I'm pretty sure that ATV tread will tear up the lawn without at least loading the tires first. Since my winter tires are loaded and chained and have no problem with this task, and since I just had a C$400 lesson in tire, rim, and fluid replacement for
one of the tires on my SCUT (the same size tire as on my GT), I'm not about to recommend that anyone buy a second set of tires and rims when the turfs that I've been using for 40 years work satisfactory in all of the tasks that I use my tractors for, like lawn mowing, about 25%, and snow duty, about 60%. Since I do not do field work, ags are not required.
I push a 54" blade on a little JD110 with nothing more than 100 pounds of extra weight thru 10-12 inches of snow and rarely spin a tire.... whats differant??? the ATV tires
For starters, the dry snows that we get in Ontario and Alberta with our sustained cold temperatures are not the same as the wetter snows that occur in locations below the border. I can drive 300 miles down to Flint or Grand Rapids Michigan, or Green Bay Wisconsin and see a substantial change in snow consistency. Travel another 200-300 miles south and there is another change.
I've had occasion to punch through the wall of snow left by the street plow after a 24" snowfall with a 54" bucket without spinning the loaded and chained turfs on my GT. For anything less than 20" of fresh snow, I also drop the 5' back blade. I don't set my tractor up for normal conditions. I set it up for
all conditions. Changing tires or adding weights at -20° C in 2' of snow is not an activity that appeals to me.
Why does JD not recommend the HDAP tires? just curious
"IF" looking for ATV tires the replacement size needs to be 1"-2" taller to maintain a level cutting deck, that is because the low PSI and softer rubber allows the tire to flatten out a little more against the ground than a higher PSI turf or ag tire might.
but then that would be a size restriction not a tread type restriction.
The size on the sidewall does not necessarily relate to the actual, in service, diameter. There have been numerous comparison pics of tires with the same nominal size from different companies, or from one company with different treads, which show this that have been posted on MTF over the years. As a general observation, aggressive tread tires seem to be taller than turfs by 1-3". I have just such a mismatched set of the same nominal size of rear 20x8-8 turfs on my LT. One has 14 psi, and the other has 9 psi to make the axle the same height above grade for both, or enough pressure change to close a 1.25" axle height difference to zero. That's a difference in diameter of 2.5", and possibly a bit more, which will eat up wheel opening clearance.
True but it still possibly limits my options.
I have not yet had the time to play with the x534 to see just how much clearance I do or do not have and just what exactly i could realistically get away with.
I have not yet seen a post from anyone with an x534 who put HDAP's or ATV type on theirs and then shared their experience about it so I am currently flying a bit blind here just trying to gather ideas and I have yet to be disappointed in that area.
While there is much reference to ATV and HDAP tires, there are
relatively few GTs so equipped. Most have turfs, many have ags, and a few who have to deal with thorns use R4 industrial tires. There may quite possibly be no one who has equipped their X534 with other than the tires that came from the factory.
I really do appreciate all the information and opinions. I am a lot smarter but not sure I am any closer to an answer LOL.
Seriously, it makes more sense to experiment with AGs and save my money until proven I need more as we just don't have heavy snows here and I think the amount of snow you push annually,, is weighing heavily (pun intended) on what you are promoting.
Thank you all again and I have the Terragrips on speed dial now if I find I need them.
Seriously, it makes even
more sense to use the tires that it came equipped with rather than experiment with tires that others have found to be wanting. (My apologies to Lance. He can make his work with the dry snows that we get in the northern climes.)
If it's experimenting that you want to do, experiment with the various methods of adding weight. It will be more productive and cost a lot less. Your tractor weighs over 750 lb. You may find that it doesn't take all that much extra weight to make it work well for you. Just loading the rear tires with windshield washer fluid will add about 100 lb. Where snow is concerned, weight trumps tread pattern. Loading a pair of turfs is cheaper than buying a pair of ATV tires.
