Does anyone have any advice on bedknife thickness? I assume the lower profile ones are for putting green heights. I have a Jacobsen eclipse 122f with 15 blade reel and groomer and was thinking that thicker bedknife would prove more resilient against mulch, acorns etc.

Yes, you are correct and plus you should get longer life out of a thicker bed knife too. A thicker one will also reduced you minimum HOC too so keep that in mind if you plan to go reel low.

I agree with MQ.

Here is a spec sheet on the Jacobsen bed knives. Most people here would be fine with the range of the High Profile knife:

Bedknife Recommended Height of Cut Range:
High Profile: 0.156" - 0.438" (4.0mm - 11.1mm)
Low Profile: 0.125" - 0.219" (3.2mm - 5.6mm)
Tournament: 0.094" - 0.156" (2.4mm - 4.0mm)
Super Tournament: 0.082" to 0.109" (2.1mm to 2.8mm)
Championship: 0.063" - 0.110" (1.6mm - 2.8mm)​

What? No one is mowing at 2mm hoc? (FYI, this is around the thickness of a nickle).

I will if you fund my water, chem & fert budget, and go to work for me while I manage the turf every day! :roll: :lol:

Mow every day? Most likely it needs every two hours to avoid the 1/3 rule. Mow when it grows to 2.5mm?
I've mowed golf greens (Bentgrass, rather than Bermuda) and depending on conditions (wet or dry) you get green powder or slime in the baskets. I never got so fancy, but mowing 2-3x throughout the day is not unheard of to maintain peak tournament conditions. Sustaining that frequency however would almost certainly result in issues.
