I think you need to look at a L or M series. You can buy pin on grapple that just replace your bucket but it's probably 15 minutes each time to switch. If you get your loader converted to the skid steer quick attach you can switch from bucket to grapple in 2-3 minutes. The other problem is lift capacity if you put a grapple on a B series you will only be able to lift 1000LBS worth of logs -depending on Capacity of your loader. With the bigger tracors you get more capacity. You could put a Grapple on the front look at Markham Welding's light duty grapple and a grapple or winch for the rear. Here's a website I found. https://www.oescoinc.com/W3-woodlot.pdf
