For the most part I haven't had any regrets on the
L3560 as most of what I do hasn't required a whole lot of hp at the PTO (not baling, & no rototiller as I specifically wanted to go the plow/disk harrow route). The most demand I've put on the PTO has been taking a 6ft finishing mower (using mulching blades) through pasture with grass that's 18-24-ish inches tall that might (occasionally) be a bit wet. In those cases I slow down and use 4-5ft of the 6ft deck as that has made me appreciate the stall-guard feature a time a or two.
However, I have really appreciated is that even with the R4 tires (which are/were same size tire across all the Grand Ls), the total width of my
L3560 (as setup) is under 72" wide which in combination with the HST has made it possible to get into/through some small/tight spaces (i.e. a 72" implement having less than 1/2" clearance to either side). ...and for the curious: yes, I've actually done that example -- multiple times in single day; rubbed the paint on the box blade doing it a few times, but the wheels were always kept clear.
Really other than the PTO power, there also isn't a whole lot of difference in the implement limitations published in the manual between the top and bottom of the Grand L line (where differences exist). For example the 3560 has trailer weight limit of 2000kg (4400lbs) and the top three models have a trailer weight limit of 3000kg (6600lbs) with all models having the same drawbar load/tongue weight of 650kg (1430lbs). Box Blade published limits are 65" & 880lbs for the
L3560 &
L4060, and 72" & 1040lbs for all other Grand L's; sickle bar mower published limits are the same for all models at 84" & 1100lbs.
Though from what I've experienced, I suspect that Kubota is conservative in at least some of those limits as I've had a 72" version one of these:
Category I & II Severe XTreme Duty Tractor Box Blade - Everything Attachments filled with a moderate-to-high clay content loam (in friable soil conditions) and in low range, low setting for range, 4WD engaged the tractor wasn't struggling in the least.
Regarding hay I've looked into that (semi-tempted to try that when/if I get more acreage), and while it might be possible to do hay with the Grand L's I think the issue would start being how well the tractor would handle the weight of the baler with a bale (especially if it's anything other than a light small square baler, or a compact baler for small tractors). While I could be very wrong, I'm not so sure the same issue wouldn't arise with the smaller M-series tractors (i.e. those below the
M6060/
M7060 & M4 ranges). By searching (via google) for the operator's manuals for different models/series you may be able to find Canadian versions in a pdf format that would allow you to see the implement specifications for that model/series.
As for cutting, tedding, and raking I suspect the Grand L's would work for a small operations with relatively short travel distances. In fact, I think the low fuel consumption would make them very tempting to use for those activities (I usually run wide open throttle and average <1 gal/hr).
Just my opinion, but depending on how far you're moving the resell value might be the deciding factor as it's been said by others before: the easiest way to move a tractor and implements cross country is in your wallet (in the form of money).
