It's a good small/mid- size dozer, hi-track and diff steer, that can do a variety of tasks on the job. Now for the type of development work I do, if I only could have one dozer it would be the D6NXL. Which makes the D5G a better value and a good little machine for grading, stripping and re-spreading curbs, slopes,etc. The D3 is too small for our operations - my T250 MTL can pretty much do what it can, D4 - like mentioned above, not much difference from a D3 and way more money. Hydrostatic, easy to operate (it's our trainer) and it has pretty good balance and enough power to tote its blade. If you will be working around buildings and such, then a D6R would be overkill and probably to big to do the job- IMO. From the pictures it looks like you are doing some sort of backfilling/grading around a concrete structure. It depends on what you want to do with the dozer. There is of course a pretty good difference between the D5G and D6R. I have 3 of the dozers mentioned: D5GXL, D6NXL and D6RXW. Both types of drive are very expensive to repair, but your chances of saving money at this time are better with the standard drive than the hydrostatic. Hydrostatic machines are very suseptable to contamination so maintenance is particularly important. The jury is still out on how long the hydrostatic drives last while good maintenance and operation can make a standard drive last more than 10,000 hours. The newer hydrostatic machines are for the most part controlled by computers and take very specialized knowledge of which for the most part is only available from new machine dealers. There a lots of mechanics around that are good at troubleshooting and repairing torque converters and transmissions. I believe the high drive machines will work any slope that the low drive machines will. The high drive finals are no better at survival than the low drive finals. I think Deere went hydrostatic with the 450H which is a very nice machine to operate. The Deere 450G I believe has a transmission, may or may not have a torque converter and is comparable to a D3C Cat which for construction machines always has a torque converter with the transmission. The D4G is current production, a low drive and fully hydrostatic. I still haven't figured what went wrong.From your post it sounds like you could use a little information about the machines you are looking for.Ī D4H machine is a high drive but they never made them with hydrostatic drives and I'm not sure but I don't think they make a high drive D4 anymore. Now whenever I jump or connect batteries I try to appropriately shield my eyes and face, just in case. I've left batteries on charge for years and never had such a thing happen. The shop circuit breaker was not tripped. I had it on the hood of my truck, whose paint had been removed by the escaped battery acid the charger had burned up, and where the charger connected into the heavy duty extension cord, its plug had burned off! Its "zip cord" supply wire was not damaged, nor the extension cord. Note: I inadvertently left a car battery charging at about 3-5 amps for several days and found it had EXPLODED (as in parts all over the place) when I returned. Its easy to get in a hurry and use the 20 or 200 amp setting on your battery charger, but batteries seem to recover well and last longer, even (or especially) if fully discharged, when slow charged on the 2 amp setting and left for about 24 hours. If it won't hold this voltage, its probably has plates shorted internally and draining itself. This is a quick alternator test.Ī fully charged battery seems to measure about 12.7 volts when disconnected. If your alternator is working you will measure about 14 volts at the battery with the engine running at operating speed, if not at idle, as well. I've gotten good service with Napa commercial truck and bus duty batteries in my tractors.
