As I had previously stated, the Massey website needs some improvement, and with todays internet based society, they could probably help their sales with more information about products and pricing. Let me see if I can address your 3 specific items from above.
1. MF recently switched loader/backhoe manufacturers. See this
thread. The change happened sometime recently, so there is mixed stock out there. A reputable dealer can help you find one version or the other if you really want. Just know that the DL100 has been discontinued and stock will be dwindling to nothing.
2. If you head over the the implements page, and click on
snowblowers, you'll see the 2360 front mount snowblower listed as compatible with the GC1700 series tractors.
3. Not sure where you are getting your pricing. The 2360 blower should be ~$3500 INCLUDING the subframe and mid--> front PTO adapter. The Kubota 50" front mount blower complete lists ~$3200, slight cheaper, but not the $1000 you stated. Hydraulic or electric shoot rotation/deflection are options for additional cost on both. Not sure wha you mean by "and adapts to other implements as well." The sub-frame on both is the basis for front blades also, and maybe the broom.
You also mentioned you could not find the brooms. Once again, go to the implements page here:
2330 Broom
I think the reason why you don't see SSQA mounts on the SCUT class tractors, is that they add weight to already low capacity loaders. In general skid steers have huge power and hydraulic flow in comparision to SCUT and even CUT sized tractors, and that huge power allows big, heavy, and strong implements to be used. A small skid steer bucket might weight 500 lbs, taking up most or all of the lower capacity of these little tractors. So, in general, having an SSQA loser on a SCUT sized tractor does not allow one to take advantage of the skid steer attachment market.
Wow, this post got long, so let me summarize. My impression is that you are disappointed with the Massey website, and therefor have a hard time considering their products. Kubota is the market leader in SCUT/CUT sized tractors. They were in the market earlier, sell more units, and have a larger availability of aftermarket attachments and such. BUT, Massey still sells a good product, and hopefully they will be able to improve their online presence. Remember, at one point in time, no company has a website...and many still made and sold quality products..
