Backhoe Weight of Tractor vs Woods BH90X BH

[heron]

A dealer is telling me the Woods BH90X weighs 1600lbs and that it would be way too much for a 4100lb tractor(+FEL).
He says I should go with a 7' or at the most an 8' BH.
He said when the dipper is extended out the tractor will be moving everywhere...?
Does anyone have experience with this particular BH and if so what weight tractor do you have it mounted on?
This BH will be mounted with a subframe, not a 3pt...tractor is a Branson 4220.
I'll be using the BH for a house site, digging stumps, some trenching, landscaping etc...maybe down the road, pool dig..?

Wow.. My dealer recomended to me the bh70x for my little Kubota 7610 "1600 lb." with the loader.. It's the perfect size for this tractor so I would think you could go bigger for sure,, What does he mean when he says " The tractor will be moving everywhere" ???

Oversized hoes on tractors is part of how tractors get busted up. When you sell backhoes as attachments to CUT's you either sell 'by the book' or undersize the hoe to the tractor as a safety factor. As a service tech, I like to see moderation on hoe sizing. If you want a 9 foot hoe, I'd like to see a 5000lb tractor strapped to it. Your mileage may vary.

Edit: The weight of the hoe is immaterial. Digging specs and breakout force, etc are the important factors to consider.

Why is the weight of the hoe not important? The 8' hoe supposedly weighs 700lbs less than the 9'. If you are digging, have the dipper extended with a full bucket, the weight of the hoe + aggregate may be well over half the weight of the machine. Therefore stability of the machine would be compromised... ie.. the entire machine gets jerked around quite a bit thereby tearing it up..
I'm sure it all depends on how you use the BH. If you are digging in loose material with no rocks or other obstacles you can get away with a larger application but if you are working on any kind of slope, in bad conditions I would think handling a BH that is a bit oversize could become troublesome.

I have a hard time imagining that an 8ft BH weighs only 60% as much as its sibling 9ft BH. I bought the Woods 90x over the 80x for my 4130lb Kioti DK40se and it seems a very good match. It feels proportionately almost identical to having a six foot BH on my previous 20hp 2100lb tractor. Both had subframes (does anyone really still use 3pt BHs???). I'd also point out that Kubota puts BHs of equal digging depth to what Kioti uses on HP equivalent tractors and the Kubotas are almost all lighter.

I cannot find the shipping weight of the 90x in Woods literature but the equivalent Kioti BH (KB2485) weighs 1200lbs without the bucket (add 150 or so for the bucket). I did find that Woods advertizes the 90x as appropriate for 30-70hp tractors. Even if you nibble at the edges of that range to compensate for marketing exaggeration, the 90x is certainly appropriate for a 4000lb tractor.

Because if you tear up your tractor with a backhoe, it won't be from carrying it around in transport position. The damage will occur from operational forces transmitted from the hoe to the tractor chassis during use. And that is directly related to the hoe's dimensions and operational spec's, not static weight.

RickB, It appears that you are ruling out all New Holland Boomer tractors from using the Woods BH-90X backhoe. I think the 4060 weighs in at about 4300lbs. Stepping up from the Boomer line would put one into the TN line, I assume, to meet your suggested criteria. I that correct?

I have a BH90X on a Kioti DK45s (4300#) with FEL (1200# approx) and ballast (800#). When I purchased it, the dealer said the sub-frame, 18" bucket, and hoe weighed 1800# total and I'm sure that is real close because I had a Woods equipment spec database but I lost it in the last computer crash ....

I have yet to experience any instability when operating the BH.

Ok, I found the spec sheet ......

BH90X for a Kioti DK45s - Base unit 1305#, sub-frame 475#, and 18" bucket 146#
BH80X for a Kioti DK series - Base unit 850#, sub-frame 400#, add bucket
BH70X for a Kioti DK series - Base unit 800#, sub-frame 350#, add bucket
BH6000 for a Kioti CK series - Base unit 600#, sub-frame 200#, add bucket

Better yet from that spec sheet you can get the range of hoes for the OP's tractor.
