I think the 4330 with 853 loader is a good choice. You won't get any significant hydraulic power increase by going to a 5030, though you would get more hp. Of course, you haven't mentioned what pto implements you will need.
Two things.
1. If cost is not an absolute killer, stop being a hard case and get HST. No one in the known universe who has gotten HST has lived to regret it. We have had many members here, including prominent Star Members such as Gordon and MChalkley, who used to disdain HST and argue forcefully here why it was unnecessary. Then they got their first HST tractor. Crack cocaine time: they are now the biggest proponents of HST alive. They will tell you it increases your efficiency for just about all tractor chores. (To clarify my earlier statement, I don't back up hundreds of times because I go around obstacles--that misstates it. I have scores of trees and bushes to go around. If I am using a MMM, I am jockeying back and forth as I try to cut close circles around each one. There might be 4 to 6 back movements to cut around each obstacle. If I have a rear mower on, I back into each obstacle or try to just graze it from several different directions. Again jockeying back and forth in short strokes, looking backwards over my right shoulder, my right hand on the ROPS, my left hand spinning the steering wheel. I have no idea how I could shift while doing this. You will be in a similar posture as you look back at a boxblade.)
2. The boxblade. I am a boxblade atheist, but if I ever got one I would want one as heavy as possible and with hydraulic scarifiers. You can tote a 1200 lb. box with a 4330. (Great counterweight.) I believe the Gearmore box is made by Cammond. We have had bad reports here from Sir Patrick of Oklahoma on the
Cammond 2C2 hydraulic scarifier box that he bought for his
L4610. Or it might even have been the heavier Cammond 4C2. As I recall the scarifier bar bent and broke in normal use and he had a big festouche with his dealer and Cammond. I'm not sure of the resolution, but I think ended up getting a heavier duty heavier model. (HEY, PATRICK, ARE YOU OUT THERE!) The thread may be buried here somewhere. So, the question is, is the Gearmore 2G2 the Cammond 2C2. I bet it is. Gearmore is a low end implement brand out in a few Western states. If I didn't know that boxblades are useless (
for me), I would, if I could afford it, get a Gannon boxblade--the high end. A notch down, I would get a Gill boxblade. Both Gannon and Gill are owned by Woods.
