I've driven thousands of miles looking at equipment and these two dozers are standing tall above the rest.Ī jd450 is about as small as I want to go. I'm at the mercy of what's available (within inspection distance) I have been looking at equipment for close to two years and for now the prices keep going up, I'm getting closer and closer to needing a dozer to complete projects. Powershift 4 speed transmission, direct drive.Īround here used JD dozers are most common torque, 17,700 approximate operating weight.
approximate operating weight, Powershift 4 speed transmission, direct drive or torque convertor.)Ĩ0 HP net, 260 ft.lb. 4 speed transmission with H-L-R reverser.ħ0 HP net, 228 ft.lb. Do you think the work you want to do is going to tax the capabilities of the 400G ( "excellent condition! with great records")? If you didn't know about that 400G would you be considering a 400 series, or just looking for 550s?Ħ0 HP net, 188 ft.lb. I have to believe the 20 HP more and 2-1/2 ton more weight will make a difference, along with the transmission, in the performance of the 550G compared to the 400G. To me the 550G should do it quicker and with less strain. Either the 400G or 550G will likely do the work you mentioned. The 550 was a step up in size and power from the 450G. The 400G has less power and weight than a 450G.
One of the things I have read is they wore the grousers quickly, most attribute this to the increased power with minimal weight increase from the 350D. The 400 was kind of a replacement/follow up for the 350D, with a bit more power. Just from looking at specs it would seem the first part of your decision is what size crawler do you want? To me you are comparing two different class machines as far as production capacity. I will start by saying I have no experience with either of those models. I assume a new pump and loop system flush is in its future for the 550 Only reason I'm concidering the 400 is it's in excellent condition! with great records.Īll oil samples on the 550 came back "green" except the hydraulic fluid has copper at 201 ppm. I Could get 1k hrs out of currant undercarriage with new track adjuster seals Will need undercarriage & hydraulic pump soon new cutting edges, muffler, seat cover, all fluids & filters, shims removed from trunnion pivot ball.

John deere 550 dozer with 3pt hitch Pc#
Roads, building pads on hillside, cleaning up behind the PC 150 excavator. I'm strongly concidering buying one of these dozersīoth are bare back used in construction/never seen the forest. My biggest concern is the transmissions (which is more reliable/durable/least exspensive to work on)
