    Replacement Headlights B7100

    Be aware that the 7100 alternator only puts out about 130w with the engine up to speed. I would size the lights for 90w or less so you still have juice left (round 3.3A @ 12v) to recharge the battery.

    L4600 vs MX4700

    A friend of mine just went from a 3200 to the 4700 I've driven both on rough ground and the 4700 is so much smoother riding and more stable it's not even a contest. My friend has 40 acres and does quite a bit of mowing in rough areas so the new MX is a real boon. Tim

    B7100 Oil Pressure Issues

    You'll need to pull the hood, radiator, alternator housing, pulleys, drop the front end down then pull the timing cover. I replaced the front crank seal and repacked the alternator bearings (they were getting dry) while I was at it. Tim

    I love this B1700, but man is it ever rough!!

    You might want to install a catch tank at the bottom of the vent tube and recycle some of that oil :)

    B7100 Upgrades / Mods

    125A alternator is around 2.3 hp to run when fully loaded, so that's a big hit unless you really need the juice.

    B7100 Dynamo Wiring

    I have an older (1979) B7100 and it has the 2 wire alternator they work find. It puts out 9A @ 14v through the regulator when the battery is down and drops off to around 2A when the battery is charged.

    B8200 cranks, but won't start

    I'd pull the injectors hook the lines up to them and see if they are firing. If not then it's a fuel delivery issue or pump problem if they are and you have good compression and glow plugs then look at the cam and see what it's doing.

    My 2nd Tractor: B5100 4wd or Used Lawn Tractor?

    Yes I got the 7100 because I can now mow my field with the belly mower up @ 5" and it has 4wd + AG tires so I'll never get stuck. It's also small enough to mow around my house and trees so seems like the perfect combination for my needs.

    My 2nd Tractor: B5100 4wd or Used Lawn Tractor?

    My mowing situation requires a belly mower a rear mount is good if you are just mowing open areas but if you have to go around stuff then a belly mower is much easier to use. Nothing wrong with a lawn tractor for just mowing if you can fine a diesel all the better, gas lawn tractors are thirsty.
