I have a pair of Ken's bolt-on grab hooks on bucket of my B3300SU, and had clevis/shackle mount from Ken in the center. In practice, I rarely used the clevis and it has been taken off. Your tractor is lighter than mine. Two hooks is enough, forget a center mount. You do not have enough FEL lift to make center mount "pay".
I would mount two hooks only, approximately in line with the lift arms. Instinctively, people want to mount chain hooks near the corners but this leads to twisting the bucket creating potential for a "sprung" bucket.
I have a third 5/16" grab hook mounted on the cross-drawbar at the rear. I use it to drag out logs into an open area, then lift logs with hanging tree prior to transporting them overland. This hook is still in gray primer.
Ken sells his hooks in 5/16" size. This is a kind of universal size as 5/16" will securely hold 3/8"-5/16"-1/4" chain, and, a little less securely 3/16" chain. I use 5/16", Grade 70 "Transport" chain. The cheapest price on this is from Lowe's or Home Depot which sell a 20' length with four grab hooks, in a plastic bag, for $40. Have the store cut it into unequal lengths of 8' + 12', buy two 5/16" Grande 70 Slip Hooks, and you are set. (Be sure to have
store cut chain. Very tough stuff.) My chain came from China. In some parts of the country it is USA chain, according to T-B-N posts. Chain will last forever unless you wrap it around tree trunks and drags trees along road where concrete can abrade chain.
It is really HOT here in Florida, and chain is HEAVY. If I could find 1/4", Grade 70 chain at a good price I would try that. However, 1/4" Grade 70 is $3.49 per foot at TSC last time I looked, so I default to 5/16". You will loose tire traction long before you will strain 5/16" chain.
Get 6' of 3/16" Proof Chain with one slip hook. When you want to pull saplings, including the roots, 3/16" chain will hold on the trunk where 5/16" will slip up the trunk. Pull saplings when the soil is wet/moist.
Ken's web site is very informative. He is a bucket hook specialty shop and no one equals his quality. I mounted hooks myself. I bought two new/sharp drills bits, mounted the pair in twenty minutes max. Hooks have been 100% tight for two years;
Grade 8 nuts/bolts provided have never loosened.
I keep my 8' + 12' chains in half a "flat" 40mm ammunition box at rear of the tractor, olive drab in Photo #4. Very handy. Ammo boxes are still widely available at Gun Stores and Gun Shows.
I use the 8' chain 80% of the time, 12' chain 19% of the time; link them with together 1%.
(Chain in Photo #3 is not Grade 70. Grade 70 has yellow chromate finish.)
