<font color="blue"> I think a grapple would make your job a whole lot easier </font>
Agree 100-110%
<font color="blue"> my experience with grapples on a FEL is not that great </font> I take this as referring to buckets with "thumb" grapples attached to them. Better than just a bucket, but not the real thing baby, uh-uh.
<font color="blue"> lots of stuff I try to pick up just doesn't work with the FEL bucket/grapple combo, and I waste a lot of time grappling air </font> See above.
<font color="blue"> would forks work better with a grapple for most things, especially long ungainly stuff? </font> A lot of the tree guys around here use, or used to use, forks. They do a lot, and have the advantage of being lighter and therefore giving you more net lifting power, but to me, using them on logs is like eating hot dogs with chopsticks. Ditto using them on brush, substitute "lobster" for "hot dogs". A (true) grapple is MUCH more productive for most tasks.
<font color="blue"> brush grapple [vs. bucket/grapple combo] .... If you are dealing with a lot of brush on a regular basis this is a must have </font> Absotively posilutely.
Other thoughts; Partsman, NICE setup. GREAT machine there! (for a JD). /forums/images/graemlins/laugh.gif /forums/images/graemlins/laugh.gif The backhoe is an ideal counterbalance. I went with a deeper lower "jaw" since I wanted as much volume as I could get for carrying more logs at a time, and scooping up brush.. I can see where the shorter jaw would give you more leverage (curling/lifting/breakout force turned into root-ripping force) if that's one of your main tasks. My tractor is set up for residential tree removal and light logging, not land clearing, so I went another way. The Bradco is a darn good all-around grapple though, I recommend it highly. 800 lbs., rugged, strong cylinders.
I still like "dedicated" electric solenoids over diverter valves, just plain easier to use, fewer steps involved in operating the grapple. Productivity up, hassle down.
Lastly, a true brush grapple will have jaws that open very wide compared to a bucket/grapple combo. You can scoop things up, or open the jaws wide and come straight down on something, like a T-Rex grabbing some hapless victim by the head and having its way with him. Very satisfying.
Truly lastly - Partsman, the other machine I was seriously considering was a JD 5320. Nice, nice machine, and I hope you know I was just kidding earlier. /forums/images/graemlins/smile.gif
